(foodconsumer.org) -- The U.S Environmental Protection Agency
announced on Oct 16, 2008 that it has set a new air quality standard
for lead at 0.15 micrograms per cubic meter of air 9ug/m3 - ten times
lower than the previous standard 1.5 ug/m3 set in 1978.
The EPA came to the decision after its
Clean Air Scientific Advisory Committee reviewed more than 6,000
studies conducted since 1990 and recommended the new standard.
The agency allows certain areas to be
cleaned by taking additional measures to reduce air emissions to meet
the new standard as later as October 2001. An estimated 1,300 tons
of lead are released into the air each year in the US.
Lead inhaled or ingested after settling
out of the air can be easily absorbed into the bloodstream and affect
many organs including children's developing nervous systems. Studies
show exposure to even low levels of lead can damage children's
development including causing loss in IQ.
Lead pollution comes from a variety of
sources including smelters, iron, and steel foundries and general
aviation gasoline, the EPA said in its statement . The new standard
would affect the industry that releases lead most.
Robert N. Steinwurtzel, a lawyer for
the Association of Battery Recyclers presenting six companies that
disassemble and recycle as many as 115 million car batteries each
year was cited by the New York Times as saying the new standard
threatens the viability of the lead recycling industry.

earlier this month lobbied the White House for a less stringent
