Study: Indoor Cooking Can Lead to Exposure to Dangerous Pollutants
Routine cooking also routinely exposes many Americans to dangerously high levels of pollutants such as carbon monoxide (CO), nitrogen dioxide (NO2) and particulate matter (PM), according to a new study in the journal Environmental Health Perspectives. While the World Health Organization is currently establishing guidelines for indoor air quality, neither the U.S. Environmental Protection Agency (EPA) nor any other U.S. agency regulate indoor air quality in non-industrial buildings. Researchers determined that during the average winter week approximately 1.7 million Californians could be exposed to excessively high CO levels simply because of cooking on gas stoves without range hoods; 12 million could be exposed to excessive NO2 levels. “That’s a lot of people in California, and those results ballpark-apply across the country,” said Brett Singer, study author and a staff scientist at Lawrence Berkeley National Laboratory (LBNL). “The EPA would say we don’t have a carbon monoxide or nitrogen dioxide problem in this country...In reality, we absolutely do have that problem; it’s just happening indoors.” The researchers listed improved ventilation; improved filtration; and improved building codes and standards as ways to combat the public health danger.

Multiple Errors Behind CDC’s Anthrax Exposure Incident
Multiple protocol breaches at a U.S. Centers for Disease Control and Prevention (CDC) laboratory led to 84 workers being exposed to live anthrax, including the fact that CDC researchers allowed only 24 hours to kill the pathogens—half the recommended time—according to Reuters. So far no one has died or become ill from the unprecedented U.S. exposure incident, but they are being treated with a vaccine and antibiotics. The errors at the biosafety level 3 facility raise new concerns over lax laboratory oversight. "If the protocol was already there, then there is really no excuse for it," said Amesh Adalja, MD, an infectious disease expert at the University of Pittsburgh Medical Center. "The question goes down to personnel and why wasn't protocol followed.” Read more on infectious disease.
Study: Autism Risk Higher in Children Whose Mothers Lived Near Commercial Pesticides
Pregnant women who live within a mile of places where commercial pesticides area used—including farms, golf courses and other public places—are more likely to have children with an autism spectrum disorder, according to a new study in the journal Environmental Health Perspectives. In a study of approximately 1,000 families, researchers determined that depending on the kinds of chemicals used, proximity to the treated area and when during the pregnancy the mother was exposed, their children were 60 to 200 percent more likely to develop autism; exposure during the third trimester brought the highest risk. Approximately one in every 68 children has autism, according to the U.S. Centers for Disease Control and Prevention. Read more on maternal and infant health.
