Should I be concerned?


We all should be concerned about air
quality and look for ways to reduce
emissions of chemicals, especially air
toxics
And we should keep the risks in
perspective
“Good surveillance
does not necessarily
ensure the making
of right decision,
but it reduces the
chances of the
wrong ones.”
Alexander Langmuir, MD,
MPH; Director of
Epidemiology for CDC
from 1949-1969

Understanding cancer risk
“one-in-a-million”




Cancer risk is enormous
“Everybody wants to go to heaven, but
nobody wants to die” – Aging is a critical
factor in cancer increase & risk
Environmental risk is incredibly small
1/1,000,000 is an enormous prevention
goal, NOT a useful thing to fear

African-American men’s risk for prostate cancer rises
from 1:8 until age 70 and then to 1:5 ever (lifetime) risk.

Risk to age 70 is 215,000/1,000,000; environmental
protection aims to keep that to 215,001/1,000,000
Data Monitoring in Rubbertown



EPA monitoring identified Jefferson County
as having the highest health risk posed by air
quality, in the Southeastern US.
State funding permitted follow-up air
monitoring studies to be performed in the
Rubbertown area during 2001
Disease risk is also able to be assessed for
asthma and cancer.

“The reason for collecting, analyzing, and
disseminating information on a disease is
to control that disease. Collection and
analysis should not be allowed to consume
resources if action does not follow.”

Epidemiology, 5: 29-37. 1976.
