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.

TEOM
data
from

to
dec
31,
2000
for
each
of
the
11
cities
also,
the

PM2.5
coefficient
(

pollutant
model)
from
the

paper
is

with
