B)  1,3-Dichloropropene (Telone); PC Codes 029001 and 029004

Metam-Sodium; PC Code 039003

Metam-Potassium; PC Code 039002 

Dazomet; PC Codes 035602 and 035607

Chloropicrin; PC Codes 081501 and 081502. 

			

The reader will find a lettered section of this report dedicated to each
compound. For each chemical, the following databases have been consulted
to find the poisoning incident data on each active ingredient.

1)  Poison Control Centers - as the result of a data purchase by EPA,
OPP received Poison Control Center data covering the years 1993 through
2005 for all pesticides.  Most of the national Poison Control Centers
(PCCs) participate in a national data collection system, the Toxic
Exposure Surveillance System (TESS) which obtains data from about 65-70
centers at hospital and universities.  PCCs provide telephone
consultation for individuals and health care providers on suspected
poisonings, involving drugs, household products, pesticides, etc.

2)  OPP Incident Data System (IDS) - reports of incidents from various
sources, including registrants, other federal and state health and
environmental agencies and individual consumers, submitted to OPP since
1992.  Reports submitted to the Incident Data System represent anecdotal
reports or allegations only, unless otherwise stated.  Typically, no
conclusions can be drawn implicating the pesticide as a cause of any of
the reported health effects.  Nevertheless, sometimes with enough cases
and/or documentation risk mitigation measures may be suggested

3)  California Department of Pesticide Regulation - California has
collected uniform data on suspected pesticide poisonings since 1982. 
Physicians are required, by statute, to report to their local health
officer all occurrences of illness suspected of being related to
exposure to pesticides.  The majority of the incidents involve workers. 
Information on exposure (worker activity), type of illness (systemic,
eye, skin, eye/skin and respiratory), likelihood of a causal
relationship, and number of days off work and in the hospital are
provided.

4) National Institute of Occupational Safety and Health’s Sentinel
Event Notification System for Occupational Risks (NIOSH SENSOR) performs
standardized surveillance in nine states from 1998 through 2003.  States
included in this reporting system are Arizona, California, Florida,
Louisiana, Michigan, New York, Oregon, Texas, and Washington.  Reporting
is very uneven from state to state because of the varying cooperation
from different sources of reporting (e.g., workers compensation, Poison
Control Centers, emergency departments and hospitals, enforcement
investigations, private physicians, etc.).  Therefore, these reports
should not be characterized as estimating the total magnitude of
poisoning.  The focus is on occupationally-related cases not residential
or other non-occupational exposures.   However, the information
collected on each case is standardized and categorized according to the
certainty of the information collected and the severity of the case.

This review offers a collection of incidents for each fumigant; for each
particular fumigant the report is divided in 4 sections: 

1- Cases reported in the Poison Control Center Database from 1993 to
2005.

2 - Cases reported in the Incident Data System (Attachment 1) from 2001
to the present;

3 - Cases reported in the California Department of Pesticide Regulation
from 1982 to 2004 or by specified period. 

4 - Cases reported in the NIOSH system from 1998 to 2003.

A) Methyl Bromide PC Codes 053201 and 053203

1.A	  SEQ CHAPTER \h \r 1 Poison Control Center Data - 1993 through 2005
for Methyl Bromide, PC Code 053201 and 053203

This section discusses results from the Poison Control Center’s Toxic
Exposure Surveillance System (TESS) from the years 1993 through 2005 and
reflects data collected for occupational, non-occupational, and children
class. The children class is five years of age or less (this definition
includes children about to become six years old, or up to 72 month old).
Cases involving exposures to multiple products and cases with unrelated
medical outcome are excluded.  Also excluded are intentional exposures.
The tables included in this section transmit acute pesticide poisoning
incidence resulting from exposure to Methyl Bromide.

The following tables evaluate the frequency of poisoning incidents for
Methyl Bromide with the composite of all pesticides for which the PCC
received a non-excluded incident report.  The frequency of events is
reported by health effect severity category (all symptoms, moderate, and
major) and by level of health care received.  A comparative ratio
provides a simple measure of the relative frequency of reported health
effects by severity category.  Knowledge of the ratios of symptoms for a
single chemical (or a group of chemicals) provides a relative measure of
the public health impact of the acute pesticide events.  In addition, a
Likelihood Ratio test shows whether the compound under study is
significantly different from the average of all other pesticides.  An
(s) indicates the proportions are significantly different.   

For a detailed explanation of the tables, see Attachment 2.

Analysis of Results

For the occupational class, all percentages of Methyl Bromide are higher
than the percentages for the composite. Methyl Bromide produces a
significant higher number of moderate cases and sends a significant
higher number of cases to a Health Care Facility (HCF). These results
may indicate the need to stress measurements for worker protection or
more training of workers on how to handle Methyl Bromide safely. For the
non-occupational class, Methyl Bromide sends a significant higher number
of cases to the HCF. For the children class there is not much exposure,
only 14 cases in 13 years of data collected. Effects of Methyl Bromide
on the entire population are well above the composite average in all
measurements and significantly higher in: symptoms produced moderated
symptoms, and cases seen in a HCF.

An irregular downward trend in total exposure, symptomatic cases, and
cases seen in a HCF is apparent for the 13 year-span of data collected
on Methyl Bromide. Calculations generate an average of 13 exposures per
year, 7 symptomatic cases per year, and 7 cases per year seen in a heath
care facility. The cluster of years 93, 95, 96, 97, and 98 has exposures
rates well above the average and then after 1998 the graphic shows lower
percentage of exposures.

2. A Methyl Bromide Incidents OPP Incident Data System (IDS)  (2001-
present)

A total of 25 cases were reported from 2001 to present dayon Methyl
Bromide. For a detailed description of each case see Attachment 1. A

3. A Methyl Bromide California Pesticide Illness Surveillance Program
Data 2000-2004

Detailed descriptions of 72 cases submitted to the California Pesticide
Illness Surveillance Program (2002-2004) were reviewed.  In 8 of these
cases, methyl bromide was used alone or was judged to be responsible for
the health effects.  Only cases with a definite, probable or possible
relationship were reviewed.  

In the first case, an import company employee unloaded a container of
straw handbags that was fumigated with the product in the Philippines
prior to shipment.  The employee reported dizziness, headache, chest
pain and tightness, skin irritation, blurred vision, and itchy eyes and
was treated by a physician.  The employee was off for 2 days from work
due to these symptoms. Another container was tested and its
contamination levels were high. 

In the second case, an applicator reported itchy feet and painful
blisters on the top of both of his feet on the second day that tree
holes were treated with product.  The man was exposed to the product
while tamping down the soil around the probe hole.  He was off from work
for 2 days due to his symptoms.  

In the third case, a worker fumigated a sea van.  Later, he pulled on
the rubber hose to remove the attached metal tubing from the sea van. 
The metal tube snapped backward and broke his safety glasses left lens. 
The man reported an irritated left eye and blurred vision.  

In the fourth case, a field worker went to the edge of the winery
property and noticed an odor.  He tested the grapes and later reported
dizziness, lightheadedness, headache, nausea, vomiting, fatigue, burning
eyes, blurred vision, and lung irritation.  

In the fifth case, an applicator reported red skin on his left foot on
the first day after performing tree-hole fumigations.  Eight days later,
the man reported itchy skin and on the tenth day a red, burning, and
swollen left foot.  His symptoms continued to get worse until he was
treated by a physician ten days later.   

In the sixth case, an applicator failed to confirm that the valve was
closed while replacing an empty cylinder on a fumigation chamber.  As he
loosened the cap, gas escaped from the valve that touched his arms and
went under his face shield and into his face.  The man reported a
headache and nausea and was treated by a physician.  The physician noted
a light chemical injury on the arm and face during the examination.  The
man was off for 2 days from work.  

In the seventh case, a shipping lines employee opened a methyl bromide
placarded container.  He entered the container to replace 2 boxes that
had fallen.  The man smelled an odor and felt faint.  

In the eighth case, an applicator performed tree-hole fumigations with
poorly maintained equipment.  The hose broke twice in 2 days and the
product got into his face and eyes.  The man reported skin and eye
irritation, nausea, vomiting, severe abdominal cramps, severe dizziness,
headache, body aches, and loss of balance that were still present 3
months after he was exposed.  He was hospitalized for 11 days.     

4. A Methyl Bromide NIOSH SENSOR

Out of 5,899 reported cases from 1998 to 2003, there are thirty-three
cases reported in the SENSOR database involving Methyl Bromide.
Individuals exposed included thirty males and three females. Twenty-five
cases were reported in California, two in Florida, four in Texas and 2
in Washington State. The cases reported produced a variety of symptoms
that are classified as 

Respiratory symptoms, eighteen cases including, cyanosis,
hyperventilation/ tachypnea, pleuritic chest pain, wheezing, etc.

Dermal symptoms, sixteen cases reported including bullae (blisters),
burns, edema, swelling, erythema flushing, rash, skin irritation and
pain

Gastro intestinal, fifteen cases reported, with symptoms described as
abdominal pain, cramping and vomiting.

Ocular symptoms, twelve cases, including pain eye irritation,
inflammation, and conjunctivitis

Cardio vascular symptoms, ten cases counting cardiac arrest,
tachycardia, hypotension, and hypertension.

Renal symptoms, two cases of polyuria (frequent passing of urine) and
proteinuria (protein in the urine)

Nervous-sensory symptoms, two cases including comma, confusion, seizure,
fasciculation (localized contraction of muscles), and

Miscellaneous symptoms, seven cases accounting for acidosis, alkalosis,
hyperthermia/fever.

Symptoms are not mutually exclusive; a patient may have many symptoms.

Analysis of Results

For the occupational class, percentages of 1, 3-Dichloropropene are
roughly the same as the composite average; the exception is on total
exposed cases where for 1, 3-Dichloropropene the exposure is
significantly higher than the percentages for the composite. For the
non-occupational class 1, 3-Dichloropropene produces a significantly
higher number of symptomatic, moderate, major, and total exposure cases;
however the clinical side of the non-occupational table shows that
exposures to 1, 3-Dichloropropene do not produce health effects
requiring hospitalization or ICU admission. For children, there is not
much exposure, only 2 cases in 13 years of data collected.  For the
combination of all classes, this is the entire population, all
measurements of symptoms and exposure are significantly higher than the
composite average while the clinical portion is well below the composite
average. This likely reflect lower usage of the chemical.

There is not a clear trend in total exposure, symptomatic cases, or
cases seen in a HCF for the 13 year-span of data collected on 1,
3-Dichloropropene; however, in the last three years the number of cases
is diminishing. The graph shows little exposure on the years 93, 94, 95,
and 96; and after a peak in 2002 a decline in exposures is noticeable.
Calculations generate a somewhat steady average of about 5 exposures per
year, 2.7 symptomatic cases per year, and 2.5 cases per year seen in a
heath care facility. 

2. B 1,3-Dichloropropene (Telone) OPP Incident Data System (IDS) (2001-
present)

A total of 12 cases were reported from 2001 to present days for 1,3-D.
For a detailed description of each case see Attachment 1. B

3. B 1,3-Dichloropropene (Telone) California Pesticide Illness
Surveillance Program Data 2000-2004

No activity was reported in the California Illness Surveillance Program
for Telone.

4. B 1,3-Dichloropropene (Telone) NIOSH SENSOR

Out of 5,899 reported cases from 1998 to 2003, there are only three
cases reported in the SENSOR database involving 1,3-dichloropropene. The
database shows exposure to males, one case in California, one in
Louisiana, and one in Michigan. The cases reported did not produce
symptoms. 

C) Metam-sodium PC Code 039003

1.C    SEQ CHAPTER \h \r 1 Poison Control Center Data - 1993 through
2005 for Metam-sodium; PC Code 039003.

This section discusses results from the Poison Control Center’s Toxic
Exposure Surveillance System (TESS) from the years 1993 through 2005 and
reflects data collected for occupational, non-occupational, and children
class. The children class is five years of age or less (this definition
includes children about to become six years old, or up to 72 month old).
Cases involving exposures to multiple products and cases with unrelated
medical outcome are excluded.  Also excluded are intentional exposures.
The tables included in this section transmit acute pesticide poisoning
incidence resulting from exposure to Metam-sodium.  Pesticide poisoning
incidents reflected in these tables are likely the result of exposure to
MITC, the environmental break-down product of metam sodium.

The following tables evaluate the frequency of poisoning incidents for
Metam-sodium with the composite of all pesticides for which the PCC
received a non-excluded incident report. 

For a detailed explanation of the tables, see Attachment 2.

Figure 1-C Total exposure, symptomatic cases, and cases sent to HCF by
year

Analysis of Results

For the occupational class, percentages of Metam-sodium are mixed for
different measurements; it produces average as compared to the composite
measure of symptomatic cases, significantly higher cases with moderate
symptoms and a higher proportion of cases with major symptoms. Exposure
is about average and cases where health care was provided are less than
the average. For the non-occupational class, Metam-sodium produces a
significant higher number of exposures than the composite average; but,
all other measurements are under the composite average. For the children
class there is not much exposure, only 27 suspected cases in 13 years of
data collected. The entire population table shows higher proportions in
symptoms, moderate symptoms, major symptoms, and total exposed;
nevertheless, cases that went to a Hospital or ICU are under the
composite measure. 

An irregular diminishing trend in total exposure, symptomatic cases, and
cases seen in a HCF is perceptible for the 13 year-span of data
collected on Metam-sodium. Calculations generate an average of about 33
exposures per year, 13 symptomatic cases per year, and 14.5 cases per
year seen in a heath care facility. Although irregular, the yearly trend
indicates a reduction on the three measurements (HCF, symptomatic, and
total exposure) with 2005 results (6, 5, and 13) well below the yearly
average.

2. C  Metam Sodium OPP Incident Data System (IDS)  (2001- present)

A total of 9 cases were reported from 2001 to present days on Metam
Sodium. For a detailed description of each case, see Attachment 1. C

3. C Metam-sodium California Pesticide Illness Surveillance Program Data

Analysis of Results

Dazomet is characterized by a low rate of exposure across the different
classes. On the occupational class, percentages of Dazomet are below the
average, except for symptoms which are not significant. For the
non-occupational class, Dazomet does not produce any significant result.
For the children class there is not much exposure, only 3 suspected
cases in 13 years of data collected. The entire population table shows
higher proportions in symptoms, moderate symptoms, and total exposed
with “symptoms” as the only measurement that is significant;
nevertheless, there are no cases that went to a Hospital or ICU. 

There is not an appreciable trend in total exposure, symptomatic cases,
and cases seen in a HCF for the 13 year-span of data collected on
Dazomet. Calculations generate an average of about 1.6 exposures per
year, 0.76 symptomatic cases per year, and 0.38 cases per year seen in a
health care facility.

Figure 1-F Total exposure, symptomatic cases, and cases sent to HCF by
year

Analysis of Results

With 22 cases in 13 years, Chloropicrin presents a low rate of exposure
across the different classes. In the occupational class, only four cases
were reported and followed, and only one case was treated in the
hospital. For the non-occupational class, Chloropicrin produced symptoms
in all followed cases. For the children class no cases were reported in
13 years of data collected. The entire population table shows higher
significant proportions only in symptoms produced. It seems that once an
individual is exposed to Chloropicrin he or she will present symptoms
(100% of cases followed).

Despite that Chloropicrin has been used for more than 75 years, there
are no cases reported from 1993 to 2000. There is a cluster of cases in
2001-2002. No appreciable trend in total exposure, symptomatic cases,
and cases seen in a HCF occurred from 2001 to 2005. From 2001 to 2005,
there is an average of 4.4 exposures per year, 2.4 symptomatic cases per
year, and 0.80 cases per year seen in a health care facility. 

2. F Chloropicrin OPP Incident Data System (IDS) (2003- present)

Only four cases were reported from 2001 to present days on Chloropicrin.
For a detailed description of the case see Attachment 1. F

3. F Chloropicrin California Pesticide Illness Surveillance Program Data
2003-2004

Detailed descriptions of 193 cases submitted to the California Pesticide
Illness Surveillance Program (2003-2004) were reviewed.  In 180 of these
cases, chloropicrin was used alone or was judged to be responsible for
the health effects.  Only cases with a definite, probable or possible
relationship were reviewed.  Table 1 presents the types of illnesses
reported by year.

According to the above activity categories, routine indoor activity was
associated with more exposures than any other category.  These illnesses
included symptoms of watery and burning eyes, headache, nausea,
difficulty breathing, scratchy throat, coughing, vomiting, stomach ache,
diarrhea, chest pain, and dizziness.

4. F Chloropicrin NIOSH SENSOR

Out of 5,899 reported cases from 1998 to 2003, there are only five cases
reported in the SENSOR database involving Chloropicrin. Four cases were
in California and one in Oregon, and all cases reported produced mild
respiratory symptoms including, upper respiratory pain/irritation and
shortness f breath. 

Summary

The table 1-G compiles results from PCC data affecting the entire
population from all Fumigants in relation to total exposed, cases
symptomatic, and visits to a health care facility. It also provides the
percentages within each column.

Table 1-G Individual fumigants, by numbers / percentages of cases by
total exposure, symptomatic, and seen in a HCF

Fumigants

	Total Exposed / Percentages	Symptomatic Cases	Cases seen at Health Care
Facility

A) Methyl Bromide	168 / 23.8%	94 / 28.7%	79 / 25.6%

B) 1,3-Dichloropropen	66/9.4%	36 / 11.0%	33 / 10.7%

C) Metam Sodium	428 / 60.7% 	171 / 52.3%	188 / 60.8%

D) Dazomet	21 / 3.0%	14 / 4.3%	5 / 1.6%

F) Chloropicrin	22 / 3.1%	12 / 3.7%	4 / 1.3%

 Total Fumigants	705 / 100%	327 / 100%	309 / 100%



According to PCC data, table 1-G indicates that Metam Sodium is the most
problematic of the fumigants of this group. Metam Sodium produces more
than 60% of all exposures, more than half of the symptomatic cases and
more than 60% of the visits to a HCF. Metam sodium is also the most
frequently used of the agricultural fumigants.  Methyl Bromide is the
second most frequently cited for pesticide poisonings with about 25 % of
total exposures, symptomatic cases, and seen in a HCF. 

Graph 1-G Cases by individual fumigants 

Recommendations

Given that Metam Sodium presents the most exposure cases of the group,
there should be specific worker training to improve the way it is
handled.  The training should include language addressing buffer zone
and time to reentry after application.

Incident#13565-1

	A pesticide incident occurred in 2001, when a grower applied the
product to three sites.  Ten individuals reported burning eyes and nose,
headache, and nausea.  Three residents that live nearby evacuated their
home for eight days.  The County Agricultural Commissioner’s Office
investigated the incident and determined that the grower did not follow
the approved worksite plan.  Instead, the grower applied the product to
a larger area than what was allowed in the worksite plan that increased
the buffer zone distances and resulted in the buffer zones extending to
adjoining properties and residences.  The grower was issued a notice of
violation for the code violations.  No further information on the
disposition of the case was reported.

Incident#13590-10

	A pesticide incident occurred in 2001, when a total of 30.5 acres was
treated with the product on a strawberry field.  Eight out of nine
residents that live nearby reported headache, migraine, nausea, dry
nose, sore throat, chest pressure, joint pain, asthma, dizziness,
sweating, coughing and runny nose.  A public meeting was held with the
concerned residents and the County Agricultural Commissioner and County
Health Commission.  Nine additional individuals filed written
complaints.  Five out of the additional nine individuals reported that
their symptoms started at least one week after the last block was
treated.  The incident was investigated by the County Agricultural
Commissioner’s Office.  No violations were found during the
investigation.  No further information on the disposition of the case
was reported. 

Incident#13913-1

	A pesticide incident occurred in 2003, when pest control company
employees, who perform port container fumigation on commodities imported
into the United States, were exposed to the product.  The workers do not
like wearing a self-contained breathing apparatus that is required when
methyl bromide concentrations exceed 5 ppm.  Exposure to high
concentrations occurred for a few seconds each time the edge of the tarp
was raised to place the exhaust fan inside the container when the
workers began aeration.  One of the workers was hospitalized for one
week and recuperated for three weeks before returning to work.  The
worker was treated by a physician and was diagnosed with methyl bromide
poisoning.  The worker reported slurred speech and a loss of balance. 
About a week after being hospitalized the worker’s methyl bromide
blood level was 50 ppm and after three weeks of recovery 16 ppm.  No
further information on the disposition of the case was reported.  

Incident#14095-1

	A pesticide incident occurred in 2003, when an imported cargo of glass
was fumigated (98% methyl bromide, 2% chloropicrin) before leaving
China.  The cargo containers were opened in the United States and
several workers were overcome by the odor and transported to the
hospital.  The workers reported teary eyes and respiratory problems.  No
further information on the disposition of the case was reported.

Incident#14264-1

	A pesticide incident occurred in 2003, when a certified methyl bromide
applicator, who works in a nursery, opened a 1.5 pound can of the
product (98% methyl bromide, 2% chloropicrin) and it splashed on his
shirt (shoulder area) and a small amount in his eyes.  He immediately
removed his shirt and flushed his eyes with water for approximately 15
minutes.  The applicator did not experience any symptoms.  No further
information on the disposition of the case was reported.  

Incident#14318-11

	A pesticide incident occurred in 2002, when household goods were
fumigated in Hong Kong and then shipped to the United States.  The goods
were sealed for one and ½ months.  While unloading and unpacking at
home the household goods still had a very strong odor.  One adult went
to the hospital and received a breathing treatment, another adult
reported chronic numbness, tingling hands, shaking, headache, memory
problems, and a sore throat.  Six children were treated by a physician
and reported shaking, severe headaches, dizziness, stomachache, and
nausea.  The residents feel better when they are not at home for an
extended period of time.  No further information on the disposition of
the case was reported.

Table Description

The following is a general brief description of the table components
that compares pesticide X with the composite average of all pesticides

Table 1 General Explanation of Comparison of Pesticide X with the
Composite

	Severity of Outcome

(Outcome determined)	Total

Exposed	Health Care 

Provided

Denominator numbers	25,549	68,005	18,084

Measures	SYM	MOD	MAJ	HCF	HOSP	ICU

Numerator numbers	578	83	9	18,084	302	219

Pesticide “X” percents	2.26%	0.32%	0.03%	26.59%	1.67%	1.21%

All Pesticides percents	21.72%	1.42%	0.12%	15.68%	4.34%	1.75%

Ratio of  Pesticide “X”

/All pesticides	0.10(S)

P =0.00	0.23 (S)

P = 0.00	0.25 (S)

P = 0.01	1.69 (S)

P = 0.00	0.38 (S)

P = 0.00	0.69 

P =0.51



The first row “Denominator numbers” presents all the numbers for
pesticide “X” that will serve as denominators in the calculation of
the percents, and they are:

In the center column, total amount of individuals exposed to pesticide
“X” (n = 68,005) or “Total Exposed”. These are cases collected
by the Poison Control Center regardless of outcome 

In the left, amount of cases followed, (n = 25,546) these cases have an
outcome determined “Outcome determined” and these cases may have
symptoms or may be determined as no symptomatic.

At the right of the table, cases that visited a Health Care Facility (n
= 18084) “Health care Provided” 

B) The row “Measures” describes the outcome of the cases: “SYM”
are those cases that were symptomatic; “MOD” cases are those that
were classified as moderate; “MAJ” cases were cases classified as
major or fatal; “HCF” are cases that went to a Health Care Facility;
“HOSP” are cases that went to a hospital; and “ICU” cases that
went to an Intensive Care Unit.

C) The row “Numerator numbers” is actually the number of cases for
pesticide “X” that presented the outcome describe in the
“Measures” row.

D) The row “Pesticide “X” percents” gives the percentages on
each measure. These percentages are calculated by dividing the numerator
number by the denominator number (from each major section of the Table
1) and multiplying by 100. For example 578, 83, and 9 are divided by
25,549 producing the respective percents 2.26, 0.32, and 0.03, for SYM,
MOD, and MAJ. In a similar fashion 18,084 is divided by 68,005 for the
percentage of cases seen in a HCF of 26.59; and for the last section of
the Table 1, 302 and 219 are divided by 18,084 to find the percentages
of cases that went to a hospital and ICU. 

E) The row “All Pesticides Percents” are percentages that were
calculated using all cases available in the PCC database with the
exception of cases involving exposures to multiple products, cases with
unrelated medical outcome, and cases where the exposure was intentional.
These exclusions make the comparison meaningful. The percentages serve
as the baseline for the comparison with a single pesticide or a group.

 

F) The “Ratio of Pesticide “X”/All pesticides” row is obtained
by dividing the percentages of the “X” compound by the “all
pesticides” percentages, to obtain a dimensionless number or ratio.
This ratio provides an idea of the relative frequency of the compound
“X”. For example, a ratio of 1 (one) indicates that the percentages
are the same for the compound “X” and the composite of all
pesticides; a ratio, say of 2 (two) indicates that the chemical under
study produces twice the effect; and a ratio of 0.5 indicates that the
compound has half of the activity of the “composite.” These ratios
provide a quick overview of the relative toxicity of the chemical.

G) Also, the “p” value that results from a Likelihood ratio test is
entered in the ratio cell and when significant (p < 0.05) then an (S) is
entered next to the ratio to mark statistical significance. A cell
marked with (S) means that the percentages that produce the ratios are
“statistically” significant and not due to chance. The percentage of
pesticide “X” could be higher or lower than the percentage produce
by the composite as indicated by the ratio. However, when mark by an (S)
the difference is significant. For example, a ratio = 1.6 (S) means the
effect produced by the compound is higher that the effect produced by
the composite and statistically different; a ratio = 0.7 (S) signifies
that pesticide “X” has a lower effect than the composite and is
statistically different. On the other hand, a ratio = 1.2, with no (S),
means that the percentage, although higher, is not statistically
different from the composite.
