Revealing the relationship between the natural world and the everyday lives of people
The US EPA is reconsidering a decision to let cement plants off the hook when it comes to mercury emissions. Tests at several cement plants showed they were emitting up to ten times the mercury being disclosed. Tracy Samilton reports:
The US EPA is reconsidering a decision to let cement plants off the hook when it comes to mercury emissions. Tests at several cement plants showed they were emitting up to ten times the mercury being disclosed. Tracy Samilton reports:
Cement plants emit mercury from both the coal they burn and from processing limestone, an ingredient of cement. But the EPA has never regulated the mercury emissions. The agency said it would be too costly for the industry. Cement manufacturers say they plan to voluntarily reduce mercury emissions over time.
But Michael Wall of the Natural Resources Defense Council says the EPA needs to exert control over the plants now.
“It would be as if we took a segment of the coal-fired power plant industry and just said ’emit mercury freely, we’re not going to do anything about it.’ That makes really bad policy and it’s really bad for our public health.”
An EPA spokesman says the agency is taking a second look at the issue, in light of stack tests showing some plants may have been grossly underestimating their mercury emissions.

Lawmakers in three states (California, Michigan, North Carolina) are considering measures to block communities from regulating the use of genetically modified seeds. The Great Lakes Radio Consortium’s Sarah Hulett reports:

Hulett reports:
More than a dozen states have already passed laws to prevent local
governments from banning the use of seeds that have been modified to
produce high-yield crops.
Peter Jenkins is with the Center for Food Safety. He says organic
farmers worry that pollen from genetically altered plants could drift into
their fields, and contaminate their crops.
“So, local control’s important to allow towns and counties to stake out
particular areas that should be set aside for organic or for GMO crops. In
some cases, you know, you could have zoning, or bans altogether.”
Supporters of the legislation say there are other ways to protect organic
crops from gene drift – including buffer zones and timed plantings. They
say it should be up to the federal government to regulate the use of
genetically modified seeds.
