PASSAGE-14
Environmental toxins which can affect children are frighteningly
commonplace. Besides lead, there are other heavy metals such as mercury, which
is found frequently in fish, that are spewed into the air from coal-fired power
plants, says Maureen Swanson, MPA, director of the Healthy Children Project at
the Learning Disabilities Association of America. Mercury exposure can impair
children‘s memory, attention, and language abilities and interfere with fine
motor and visual spatial skills. A recent study of school districts in Texas
showed significantly higher levels of autism in areas with elevated levels of
mercury in the environment. ―Researchers are finding harmful effects at lower
and lower levels of exposure, says Swanson. ―They‘re now telling us
that they don‘t know if there‘s a level of mercury that‘s safe.
Unfortunately, some of these chemicals make good flame retardants and have been
widely used in everything from upholstery to televisions to children‘s
clothing. Studies have found them in high levels in household dust, as well as
in breast milk. Two categories of these flame retardants have been banned in
Europe and are starting to be banned by different states in the United States.
The number of toxins in our environment that can affect children may seem
overwhelming at times. On at least some fronts, however, there is progress in
making the world a cleaner place for kids—and just possibly, reducing the
number of learning disabilities and neurological problems.With a number of
efforts to clean up the environment stalled at the federal level, many state
governments are starting to lead the way.And rather than tackle one chemical at
a time, at least eight states are considering plans for comprehensive chemical
reform bills, which would take toxic chemicals off the market.

ejected in the air from power plants using coal.
