Endocrine Disruptor Safety Thresholds May Require Reassessment, New Study Suggests

Endocrine disruptors have been studied in great detail in recent years, a result of the awareness that these chemicals have a presence in day to day life. Many household products, especially those containing plastics, have been identified as containing endocrine disruptors, but industry groups have maintained that in the small levels these chemicals are present, they are not a threat for human consumption.

Scientists Believe Link Between BPA and Liver Cancer Found

Researchers at the University of Michigan School of Public Health were conducting an experiment to determine the links between bisphenol A exposure and obesity recently, but the results of their study were far more incriminating than they'd imagined, giving them reason to believe that BPA and Liver Cancer are directly linked.

Scientist Finds Plastic Pellets in Gooseneck Barnacles

A scientist working on gooseneck barnacles has discovered plastic pellets in his dissected specimens, a finding which spells bad news for a future study. John Upton of Grist writes:

Bisphenol A Debate Drags on as Endocrine Disruptors are Identified

Bisphenol A has been making headlines with fair regularity lately as a bitter debate over its regulation as a chemical is waged. The number of studies and research projects that have found reasons for concern over the near ubiquitous nature of bisphenol A are growing, but voices from the chemical industry remain adamant that the chemical is safe. According to Lynne Peeples of the Huffington Post, the danger of this ongoing battle could affect more than just bisphenol A and those in contact with it.

Scientists Who Opposed EU Chemical Policy Have Industry Ties

Recent reports indicate that a group of scientists who have been vocal in their opposition of the European Union's provisional chemical policy may not be impartial researchers due to industry ties.

Debate Over Regulation of Endocrine Disruptors Builds

The past few weeks have seen growing intensity in the scientific community as researchers continue to add their voices to the battle over the regulation of endocrine disrupting chemicals. An article in Scientific American this week calls attention to the academic barbs being traded via scientific journals. Daniel Cressey writes that the fighting recently resurfaced over a leaked policy on endocrine disruptors from the European Commission instigated debate. According to Cressey:

Harvard Study Finds BPA May Cause Human Infertility

A study from Harvard University has determined that bisphenol A may be causing higher instances of birth defects and infertility. According to an article published by Stephen Reinberg of US News, researchers from Harvard have concluded from their study that bisphenol A's endocrine disrupting properties may play a role in about 20 percent of documented cases of unexplained infertility. Reinberg writes that the study involved exposing 352 eggs from 121 consenting patients to different levels of bisphenol A.

Study Claiming BPA 'Harmless' May Not Be Scientifically Sound

Recently, a study by scientist Justin Teeguarden has been circulating the news due to its claim that bisphenol A is not a significant threat to the human body. Tom Philpott of Mother Jones writes that Teeguarden gave a presentation at the American Association for the Advancement of Science last month that assured those present that the amount of bisphenol A needed to successfully mimic estrogen in the human body was much higher than the  dosages consumers get from products containing BPA. In other words, Teeguarden asserted, BPA is not a concern to the consumer.

Classify Plastics As Hazardous Waste, Scientists Urge

An article published via Waste & Recycling News yesterday shared the story of a group of scientists who feel they have a solution to the ever-present problem of keeping plastics out of  the ocean: classifying it as toxic waste. According to the article, this group of scientists is calling upon the 1989 Montreal Protocol, which classified chlorofluorocarbons as toxic waste and achieved a successful result in limiting their presence in the environment. 

Study Finds Ants Are Contaminated With Phthalates

The chemical compounds known as phthalates were found to be present in ants during a study conducted by entomologist Dr. Alain Lenoir, according to a new article posted on Inhabitat.com. Contributor Morgana Matus writes that even these tiny organisms were found to be susceptible to the chemical compound, which is released into the atmosphere as plastics degrade. Matus reports:
