Shocking finding about the association of chemical pollution and the sex of fish. Today's post is shared from latimes.com Pennsylvania's Department of Environmental Protection has begun an extensive sampling of chemical contaminants in response to the discovery of intersex fish in three of the state's rivers, a department spokeswoman said. Male fish carrying eggs were found in the Susquehanna, Delaware and Ohio river basins, a sign that the water may be tainted with chemicals, the U.S. Geological Survey found in research released Monday. Amanda Witman, a DEP spokeswoman, said the agency is testing two tributaries of the Susquehanna River: Juniata River and Swatara Creek. The USGS research said that two fish species, smallmouth bass and white sucker, were exhibiting intersex characteristics due to exposure to endocrine-disrupting chemicals — hormones and hormone-mimicking chemicals that caused the male fish to produce eggs. "The sources of estrogenic chemicals are most likely complex mixtures from both agricultural sources, such as animal wastes, pesticides and herbicides, and human sources from wastewater treatment plant effluent and other sewage discharges," said Vicki Blazer, a fish biologist and lead author of the USGS study. Estrogenic chemicals disrupt the endocrine system, which regulates the release of hormones such as estrogen and testosterone. This interferes with the fish's ability to reproduce. Some of the compounds and contaminants found were new, and researchers had to develop new laboratory test procedures... |

Reducing Worker Exposure to ETS
What better time than during the American Cancer Society’s annual Great American Smokeout, to highlight the benefit of comprehensive smoke-free workplaces on the health of workers. Furnishing a smoke-free work environment has been shown to both reduce exposure to environmental tobacco smoke (ETS) among non-smokers, and also to decrease smoking among employees. In Massachusetts, recent surveillance findings suggest that one approach to reaching that goal – comprehensive state laws mandating smoke-free workplaces – had a measurable positive impact.
The U.S. Surgeon General reports that there is no safe level of exposure to ETS, also known as secondhand smoke (USDHHS 2006). Workers can be exposed to ETS in their workplaces if co-workers or members of the public are permitted to smoke. ETS causes lung cancer and heart disease, and is also linked to respiratory diseases. Not only does ETS worsen asthma but it also increases the likelihood of developing asthma. In 2004, Massachusetts became the third state behind Delaware and New York to pass a comprehensive law, banning smoking in bars, restaurants and non-hospitality workplaces. The Massachusetts Smoke-Free Workplace Law (M.G.L. Ch. 270, § 22) requires all enclosed workplaces with one or more employees to be smoke-free. We recently presented findings from the Behavioral Risk Factor Surveillance System demonstrating that... |

Workers’ Compensation Task Force meets
The Workers’ Compensation Task Force reconvened Friday to kick off a series of monthly meetings designed to further address the state of Delaware’s workers compensation premiums.
Four months earlier, the task force presentation an 18-point plan to reform the state’s increasing workers’ compensation. The plan was translated to legislation and signed into law in June. “We have had some developments since we issued our report,” said Lt. Gov. Matthew Denn, the chairman of the 20-member task force. Since 2007, the state has been working to cut back on high premium rates. Insurance legislation enacted in 2007, Senate Bill 1, included provisions to create a Health Care Advisory Panel (consisting mostly of health care personnel) to reform the payment system and develop practice guidelines for the most common workplace injuries, as well as create a Data Collections Committee. The reforms passed helped the state facilitate nearly a 40 percent decrease in rates, jumping from having the nation’s third most expensive workers compensation premiums in 2006 to the 34th most expensive by 2010, according to the Oregon Workers’ Compensation Premium Rate Ranking Summary. But, the premium rate has skyrocketed since then, rising over 40 percent in two years. The legislation, House Bill 175, addresses the task force’s four major workers compensation concerns. Curbing the high workers compensation medical costs was a priority, so the... |
