The 1369th meeting of the Connecticut Academy of Arts
and Sciences was held on Wednesday, May 10, 2006 at 5.00p.m.
at the New Haven Lawn Club. Some 50 members and their guests
attended the lecture and the dinner following. The members and
their guests enjoyed cocktails before the lecture, which began
at 5.30p.m. Dr. Ernest Kohorn, President of the Academy, welcomed
the audience and introduced the speaker, John Wargo, Professor
of Environmental Risk Analysis and Policy at Yale University.
Professor Wargo's talk was
entitled "Environment, Health and Children: The Origins
of Inequality in the Distribution of Health". He noted that
his talk had been incorrectly advertised by the Academy as the
"Origins of the Inequality in the Distribution of Wealth,"
but the error had given him pause for thought. Although he considered
that there was indeed a connection between the two concepts,
he would continue with his talk on health.
Dr Wargo said that it was important to understand how risks are
distributed and how to craft public policy in order to protect
women and children. Air quality and its effects on health was
one of the biggest threats to children. Environmental quality
does indeed affect the incidence of some illnesses. The Environmental
Protection Authority {EPA} states that air quality has improved,
but, says Professor Wargo, it depends how you measure it and
also where you spend your time. Many pollutant chemicals persist
in the environment and cause late damage. For example, strontium
90 is "rained down, goes into plants and then arrives on
our dinner table. The increased use of coal by the Chinese affects
our air. It affects the West coast first and eventually also
the East coast of the United States. Professor Wargo said there
is a concentration of highway freight transportation in the northeast
of the United States and that together with the prevailing wind
causes the worst smog days in the N.E. Air pollution from industry
is concentrated in the southwest of Connecticut. Ozone and particulate
levels peak at midday but the EPA average the numbers out. The
air quality when driving on I 95 and I 91 is bad but sitting
in traffic in downtown Los Angeles is worse. There are more vehicles
on the road now and they are being used more. In 1950, the EPA
set standards to protect the population's health. States however
were allowed to average the standards over 3 years so the politics
of air quality were the politics of statistical standards. The
N.E. of the U.S. has the highest consumption of heating fuel,
and relies on diesel fuel, which has high sulphur content. The
NE also has the highest incidence of asthma in children. So the
most susceptible population to this form of pollution are at
both ends of the life cycle: those with asthma, cardiac problems,
bronchitis or emphysema The clean air act provided no protection
for this group. If you put meters on children to measure the
polluted air they were breathing, there would be bursts at the
beginning and at the end of the day since that is when they travel
on buses or in cars. (Professor Wargo used his daughter to measure
the air pollution but had to pay for it dearly. She did not want
to travel on a school bus any more so he drove her to school
every day!) When the idling of school busses was found to be
a big pollutant and that the exhaust of one bus was going straight
into the cabin and the driver of the bus behind, the State of
Connecticut reacted well and limited the idling. This was a policy
success story. (The drivers said they idled because they were
afraid that their buses would not restart. This was based on
their experiences with the older buses several years ago!) The
EPA does not measure bursts of pollution since the measures are
averaged over 24 hours and then 3 years, but these bursts are
significant in health risks. Professor Wargo concluded by saying
that the government does not manage environmental issues on a
scale that matters to the individual. There needs to be political
will to apply the available information. Initiatives are however
being taken at the State level of government.
