Sun, Nov 14, 2010 from The Tampa Tribune: Investigation shows elevated levels of lead in grocery bags Publix officials will revamp their lineup of re-usable grocery bags sold in their stores after a Tampa Tribune investigation found elevated levels of lead in material of some bags.
Tribune tests showed certain bags from Winn-Dixie and Publix stores had levels of lead that concerned health officials. And some bags had enough lead that they could be considered hazardous waste if residents put them in their household trash.
This follows a similar issue that led the Northern grocer Wegmans to voluntarily exchange thousands of their bags.
Publix officials stress that their bags comply with current federal laws regarding lead content. But given the Tribune findings, and lower thresholds due next year, Publix is asking bag suppliers to find ways to make bags with less lead...over time lab experts note the bags wear down and paint can flake off, and eventually re-usable bags would accumulate in landfills, presenting another ecological issue.. ...
Worst of all the lead makes the bags a lot heavier!
Fri, Nov 12, 2010 from Our Amazing Planet: Study: Common Flame Retardant Polluting Globally A widely used flame retardant taints the air and water between Greenland and Antarctica, a new study reveals. The chemical, Dechlorane Plus, joins a list of chemicals that are detected far from the factories where they were originally created. Scientists are unsure how Dechlorane Plus travelled so far, or even how dangerous it is in these environments. But now that they've found it, the next step is to figure out what it will do to marine ecosystems.
"The facts on how bad [Dechlorane Plus] is to the environment has really yet to be worked out," said Ed Sverko of Environment Canada. Sverko also studies Dechlorane Plus, but was not involved with the study. ...
Something tells me Dechlorane Plus will be a minus.
Fri, Nov 12, 2010 from Environmental Health News: Antimicrobials murderous in nature When released into waterways from wastewater treatment plants, the antimicrobial triclosan continues to do what it was designed to do -- kill bacteria -- and starts doing what it was not designed to do -- interfere with photosynthesis in algae.
The results from a study in Spain suggest that triclosan carries a high environmental risk and warrants concern about its presence in waterways. The findings agree with prior studies that find the antimicrobial is toxic to bacteria at levels measured in water.
However, this is one of just a few published studies to report that triclosan can reduce photosynthesis in a type of algae known as diatoms. Through photosynthesis, diatoms produce oxygen and food that other aquatic organisms rely upon. It is estimated that 80 percent of the oxygen in our atmosphere comes from diatoms, making these microscopic organisms essential for life on earth.
Triclosan is an anti-microbial chemical widely used in personal care products, like toothpaste and anti-bacterial hand soap. It is added to cleaning products and is applied to many items, including clothing, toys, shower curtains and kitchenware. ...
Fri, Nov 12, 2010 from Baltimore Sun: Intersex fish found in Delmarva lakes Scientists have found more intersex fish in Maryland, this time on the Eastern Shore, and their research suggests one possible source of the gender-bending condition could be the poultry manure that is widely used there to fertilize croplands.
Six lakes and ponds on the Delmarva Peninsula sampled over the past two years have yielded male largemouth bass carrying eggs, according to University of Maryland scientists. Those are the first intersex fish reported there, though researchers found the condition several years ago in smallmouth bass in the Potomac and its tributaries, and recently found it in smallmouth bass in the Susquehanna.
Intersex fish are a concern, scientists say, because they could be indicators of contaminants in the water, affecting their growth and reproduction. ...
But intersex fish taste ... I dunno, so much more complex.
Mon, Nov 8, 2010 from Environmental Health Perspectives: Chemicals in cosmetics, moisturizers linked to DNA damage in human sperm. One type of paraben preservative -- butyl paraben (BP) -- was linked to DNA damage in men's sperm, according to a study that compared the levels of this compound to several reproductive measures in men. DNA damage in sperm cells can have negative effects on men's reproductive potential.
The findings indicate that the higher the BP levels, the more DNA damage the sperm had. The relationship was even stronger when BP and bisphenol-A (BPA) levels were considered together.
This is the first study to look at the relationship between paraben levels in men and sperm health. A prior study found that the late stages of sperm production were affected in mice fed BP. The results warrant further investigation into effects of parabens on men's sperm health as well as their effects on female reproductive systems and pregnancy and birth measures, given that women typically have higher levels of parabens than men.
Parabens are a group of antimicrobial chemicals often used to preserve cosmetics, pharmaceuticals and sometimes food. They are added to numerous personal care products -- including make-up, shaving gels, lotions and creams -- and some food and drinks. ...
That my shaving gel may make me less manly just flies in the face reason!
