This
memorandum
supplements
the
statistics
reported
in
the
memorandum
"
Updated
statistical
information
on
air
quality
data
from
epidemiologic
studies"
(
Ross
and
Langstaff,
2005)
with
statistics
for
six
additional
epidemiologic
studies.

In
Fall
2005,
we
made
an
additional
effort
to
contact
investigators
of
PM2.5
studies
for
which
upper
percentile
data
weren't
available.
These
studies
used
PM
air
quality
measurements
that
were
made
independently
by
the
investigators
and
thus
not
available
in
EPA's
air
quality
system.
We
were
able
to
obtain
air
quality
data
that
had
been
used
in
a
number
of
studies;
attached
is
a
compact
disk
containing
the
data
files
provided
(
Attachment
A).
The
following
are
the
mean
and
98th
percentile
PM2.5
concentrations
for
those
studies:
