Mercury is a potent neurotoxin that harms people and the environment.
Developing fetuses and children are especially at risk as even low-level
mercury exposure can impede brain development, causing learning disabilities,
impaired memory and motor skills, and decreased IQ.
In early 2004, EPA scientists estimated that one
in six women of childbearing age in the U.S. has sufficiently high mercury
blood levels to put 630,000 of the four million American babies born each year
at risk of neurological damage. A recent study published by the Center for
Children’s Health and the Environment at the Mt. Sinai School of Medicine put a
dollar value on one aspect of this health risk. In the study, “Mental
Retardation and Prenatal Methylmercury Toxicity,” Mount
Sinai’s pediatricians found that in 1566 American children each
year, mercury causes a big enough loss in IQ to result in mental retardation,
with a monetary cost to our economy of approximately $2 billion per year.
Georgia’s
power plants emit 76 percent of the mercury that ends up in our state’s
waterways where it accumulates in the fish that we ultimately eat. This
pollution has resulted in mercury-related fish consumption advisories that
cover every mile of our coast, more than 41,000 acres of our lakes and 2,500
miles of our rivers.
But we can clean it up. Inexpensive, modern
pollution controls can capture 90 percent of a power plant’s mercury.
In the past year Georgia has worked to draft a state
level mercury rule aimed at cleaning up our state’s coal-fired power plants.
Unfortunately one of their original proposals- a 90 percent reduction in
mercury emissions by 2012, has been significantly weakened by the utility lobby.
The current rule will require the installation of
pollution controls over the next nine years but it gives no guarantee that
reductions close to the 90 percent needed will occur and allows polluters to
trade credits inside and outside of the state.
This trading may cause concentrations of mercury pollution that further
threatens public health. To learn more about the current state mercury
rule read our recent testimony to the Department of Natural Resources.
