"No kid should ever play in arsenic. Especially at school. Yet many probably do, according to findings of a study presented today."

"Elevated levels of two plastic-softening chemicals in pregnant women's urine are linked to less-masculine play behavior by their sons several years later, according to a study published last week in the International Journal of Andrology."

NIEHS Director Linda Birnbaum says she is concerned that as U.S. manufacturers shift away from toxic chemicals in consumer goods to alternative chemicals, "we kind of jump from the proverbial fry pan into the fire."

"No one would choose to eat polychlorinated biphenyls, or PCBs -- yet we unwittingly do. And a new study finds that the cost of their pervasive contamination of our food supply can be high blood pressure, a major risk factor for heart disease."

"Children's toys carrying the Barbie and Disney logos have turned up with high levels of lead in them, according to a California-based advocacy group -- a finding that may give consumers pause as they shop for the holiday season."

"The Environment Report's Shawn Allee investigates Dow Chemical and dioxin contamination in mid-Michigan. Central Michigan has lived with toxic dioxin pollution in two major rivers and Saginaw Bay for decades. Shawn looks at who's been affected, why it's taken so long to clean up, how the science behind dioxin has played into this, and what the cleanup means for the rest of the country."

"Smaller than a virus and used in more than 200 consumer products, silver nanoparticles can kill and mutate fish embryos, new research shows."

As U.S. chlorine plants convert to cleaner technology, they are leaving behind large stocks of mercury. There is a danger that mercury will find its way to dangerous and polluting uses on the global market. Efforts to ban mercury export have not been effective.
