Obama Administration's Scientists Admit Alarm Over Chemicals (The Guardian (UK))

The Obama administration is facing concern from government scientists about the use of dispersants in the Gulf of Mexico. Leading scientists recently wrote a letter to BP and the Obama administration asking them to release all of the scientific data related to the spill. The National Wildlife Federation explained, "Just as the unprecedented use of dispersants has served to sweep millions of gallons of oil under the rug, we're concerned the public may not get to see critical scientific data."

EPA Develops Software to Secure Nation's Water Supply (EPA)

The EPA and DOE have developed free water quality software to enhance a water system's ability to detect contaminants, such as pesticides, metals, and pathogens, able to distinguish between natural variation in water quality and hazardous contamination. The EPA's Office of Research and Development stated "This cutting-edge technology helps to protect all Americans...and allows water utilities to quickly advise customers when their water is not safe to drink."

BPA Linked to Decreased Sperm Quantity and Quality (Environment News Service)

Researchers have found a connection between urinary concentrations of Bisphenol A, or BPA, and decreased sperm quality and quantity. The results of the study show that the sperm concentrations of men with the highest concentrations of BPA were 23 percent lower on average with a 10 percent increase in sperm DNA damage. According to the study's lead author, "Much of the focus for BPA is on the exposures in utero or in early life...but this suggests exposure may also be a concern for adults."

Chemicals in Rivers Linked to Sexual Changes in Fish (The Canadian Press)

University of Calgary professors have found that hormone-altering chemicals in rivers, such as synthetic estrogens and agricultural by-products, are changing the sexes of a small species of minnow. One of the researchers asserted "I think we need to look at this a little more carefully and ask, what is the message the fish are telling us. If the fish are showing bent genders and people are drinking the same water . . . we need to try to evaluate that risk.”
