During
our
look
at
comments
and
the
new
science
assessment
related
to
a
recent
study
by
Burnett
and
colleagues
in
multiple
Canadian
cities
(
2004),
some
questions
came
up
about
the
peak
values
and
the
PM
analysis.
I
spoke
with
Dr.
Burnett
by
phone
on
July
6th
to
see
if
we
could
some
additional
information,
and
he
sent
the
following.

Re:
Canadian
TEOM
data
attached
is
the
distribution
of
the
PM2.5
TEOM
data
from
jan
1,
1998
to
dec
31,
2000
for
each
of
the
11
cities
also,
the
TEOM
PM2.5
coefficient
(
in
a
single
pollutant
model)
from
the
AEH
paper
is
1.13%
with
a
standard
error
of
0.466%
(
this
is
not
included
in
the
paper
­
do
not
know
why
­
just
getting
old
I
guess)
