S 1361, introduced by Senator John Kerry (D-MA), and HR [...]

(Beyond Pesticides, July 22, 2011) Parallel bills have been introduced in the U.S. Senate and U.S. House of Representatives designed to increase federal research on endocrine disrupting chemicals and ensure public safety by restricting or eliminating chemicals found to present unacceptable risks to public health. S. 1361, introduced by Senator John Kerry (D-MA), and H.R. [...]

(Beyond Pesticides, June 20, 2011) In a study published this week in the journal Pediatrics, researchers report findings that link mothers’ exposure to organochlorine pesticides during pregnancy with infants’ sizes at birth. The trend shows that the more mothers are exposed to the pesticides during pregnancy, the higher the chances are for reduced birth weight [...]

(Beyond Pesticides, May 9, 2011) The Endocrine Disruptor Exchange Inc. (TEDX), founded by Theo Colborn, PhD, has released a list of chemicals with the potential to affect the endocrine system. According to TEDX, every chemical on the TEDX List has one or more verified citations to published, accessible, primary scientific research demonstrating effects on the [...]

(Beyond Pesticides, April 28, 2011) In recognition of the 3rd annual Save the Frogs Day, a “Save the Frogs/Ban Atrazine Rally” will be held tomorrow, Friday, April 29th in Washington, DC. The rally will take place at the steps of the U.S. Environmental Protection Agency (1200 Pennsylvania Ave, NW), and is intended to raise awareness [...]

(Beyond Pesticides, March 10, 2011) The American Public Health Association (APHA) recently adopted 17 new policies at its 138th Annual Meeting in Denver, addressing a broad range of public health concerns, including a new policy calling for greater government action to protect the public from endocrine-disrupting chemicals (EDCs). The policy statement follows official positions released [...]

(Beyond Pesticides, February 16, 2011) Many agricultural pesticides –including some previously untested and commonly found in food– disrupt male hormones, according to new tests conducted by British scientists. Meanwhile, U.S. researchers at the National Institutes of Health have found that people who used two specific varieties of pesticide were 2.5 times as likely to develop [...]

(Beyond Pesticides, December 8, 2010) A new study finds that oral contraceptives are not the main culprit in estrogenic pollution of U.S. rivers and drinking water. Instead, the contribution of contraceptives is quite small compared to other human, industrial and agricultural sources, including pesticides. Recent observed feminization of aquatic animals has raised concerns about estrogenic [...]

(Beyond Pesticides, November 18, 2010) Yesterday, the U.S. Environmental Protection Agency (EPA) announced that it has identified a list of 134 chemicals that will be screened for their potential to disrupt the endocrine system, along with a draft of the policies and procedures that the agency will follow for testing. Endocrine disruptors are chemicals that [...]

(Beyond Pesticides, September 14, 2010) A new study confirms that indoor uses of consumer products, including pesticides, are the primary sources of indoor exposure to endocrine disruptors –chemicals that disrupt hormones and cause adverse developmental, disease, and reproductive problems– and shows that indoor levels are higher than those outdoors. Researchers from Silent Spring Institute, Columbia [...]

(Beyond Pesticides, August 31, 2010) As the Environmental Protection Agency (EPA) continues its review of the popular herbicide atrazine, a new study shows that male rats prenatally exposed to low doses of the gender-bending chemical are more likely to develop prostate inflammation and to go through puberty later than non-exposed animals. The research adds to [...]

(Beyond Pesticides, January 14, 2010) Stating that current water-quality criteria does not reflect the latest scientific knowledge, The Center for Biological Diversity petitioned the U.S. Environmental Protection Agency (EPA) to establish new water-quality criteria for numerous endocrine-disrupting chemicals (EDC) under the Clean Water Act. If adopted, it will be a big step in regulating and [...]

(Beyond Pesticides, December 21, 2009) Earlier this month, Congressman Jim Moran of Northern Virginia and Senator John Kerry of Massachusetts introduced legislation to explore linkages between hormone disrupting chemicals in the environment and everyday products and the dramatic increase of autism, hyperactivity, diabetes, obesity, breast cancer, prostate cancer and other hormone related disorders. After the [...]

(Beyond Pesticides, December 15, 2009) Exposure to the endocrine-disrupting herbicide atrazine triggers the release of stress hormones in rats, according to a new study published in the December 2009 issue of the journal Toxicological Sciences. The researchers believe this may explain how the popular weed killer produces some its harmful reproductive effects. The study, “Characterization [...]

(Beyond Pesticides, November 17, 2009) According to a new study by researchers at the University of Wisconsin-Madison, exposure to low levels of the organophosphate insecticide chorpyrifos during pregnancy can impair learning, change brain function and alter thyroid levels of offspring into adulthood for tested mice, especially females.
