One of the U.S.
Environmental
Protection Agency’s
most potent
regulatory weapons
is the 2010 claim that
fine particulate matter
(soot & dust called PM2.5)
in outdoor air
kills people.
EPA has claimed
manmade PM2.5
causes as many
as 500,000 deaths
annually
PM2.5 is very small / fine
soot and dust in the air.
It has natural sources
(e.g., forest fires,
volcanoes, pollen,
molds) and also
manmade sources
(e.g., smokestack/tailpipe
emissions, fires in fireplaces,
campfires, and BBQ grills,
and tobacco smoking).
EPA admitted
in federal court
that its PM2.5
studies, because
of their exclusively
statistical nature,
prove nothing
by themselves.
No laboratory animal
has ever died from PM2.5
in an experimental setting
— even though animals
have been exposed
to levels of PM2.5
as much as 100+ times
greater than
human exposures
to PM2.5 in outdoor air.
EPA has tested
many air pollutants,
including very high
exposures to PM2.5,
on over 6,000 human
volunteers.
Many of the volunteers
were elderly or already
health-compromised
— groups EPA claims
are most susceptible
to dying from
PM2.5 exposures.
EPA admitted there
have been no deaths
or any dangerous
adverse events
clearly caused by
these PM2.5
exposures,
as high as
21 times greater
than allowable
by EPA’s own
air quality rules.
Indoor exposures to PM2.5
can easily exceed outdoor
exposures, by as much as
a factor of 100.
Although EPA claims
that almost 25%
of annual U.S. deaths
are caused by PM2.5,
no death has ever been
medically attributed
to PM2.5.
So EPA’s claim about
PM2.5 causing death
is not supported
by any data.
There is no generally
accepted medical or
biological explanation
for how PM2.5
could possibly
cause death.
EPA's junk science
also claims CO2
is a pollutant, rather
than the staff of life
on our planet.
And the Trump
Administration
has not deleted
any of the EPA
junk science.
