A recent study indicates expectant mothers who are exposed to
air pollution see damage to the genetic make up of their newborns.
That might increase the babies’ risk of contracting cancer later in
life. The Great Lakes Radio Consortium’s Lester Graham reports:


The expectant mothers were asked to carry air monitors in backpacks to see how much they were exposed to air pollutants. The Columbia University researchers chose 60 mothers in low-income neighborhoods. Dr. Frederica Perera is chief author of the study.


“All of our mothers in the study were non-smokers. So, the primary source of these pollutants in air would be things like motor vehicles, emissions from residential heating units, burning fossil fuel and also from power plants located even fairly far away.”


It’s the fist study to make a connection between air pollutants causing genetic changes in the womb that could increase cancer risk. Earlier studies by the researchers already revealed greater prenatal exposure to air pollution caused lower birth weights and smaller heads in newborns.

Study: Banned Pesticides Affect Child Development

Columbia University professors say they have found the first evidence that two banned pesticides are harmful to humans. They say their study vindicates a decision by the Environmental Protection Agency to phase out the chemicals based only on preliminary research on animals.

Columbia University professors say they have found the first evidence that two banned pesticides
are harmful to humans. They say their study vindicates a decision by the Environmental
Protection Agency to phase out the chemicals based only on preliminary research on animals.
The Great Lakes Radio Consortium’s Tracy Samilton reports:


Chlorpyrifos and diazinon were once found in over-the-counter products for
in-home pest control. The EPA started to phase out the chemicals four
years ago, after preliminary research showed the chemicals could be
harmful. The new study tracked a group of pregnant women in New York
before, during and after the ban. It found that women with the highest
concentration of the pesticides in their blood had smaller and shorter
babies than those with less exposure. Robin Whyatt is with Columbia’s
Mailman School of Public Health. She led the study. She says there’s no
question the research vindicates the EPA’s decision.


“It certainly supports that that was a good regulatory decision and this also shows that regulation
works.”


While Whyatt says the ban was good policy, she says more studies should be
done to confirm her results. Chlorpyrifos and diazinon are still widely
used in agriculture. Some environmental groups say the chemicals should
also be phased out there.

Injection Wells Blamed for Earthquakes

Seismologists are blaming a deep-injection well once used for disposal of liquid waste for recent earthquakes in Northeastern Ohio. They say the area had no history of earthquakes before the well was drilled. The Great Lakes Radio Consortium’s Christina Shockley reports:
