But despite the dramatic change in our driving habits lead pollution in the environment remains a health hazard and, according to the latest research from Children of the 90s, one to which children are particularly vulnerable. http://www.physorg.com/news172423298.html Medicine & Health Thu, 17 Sep 2009 17:00:10 EST news172423298 Growing evidence shows that exposure to lead in the environment is associated with cardiovascular disease, including increased risk of hypertension. However, those studies have looked at lead concentrations in blood, not bone lead, a better indicator of cumulative lead exposure over time. In a new study, researchers at the Harvard School of Public Health (HSPH) and the University of Michigan School of Public Health found that bone lead was associated with a higher risk of death from all causes, particularly from cardiovascular disease. It is the first study to analyze the association between bone lead and mortality. http://www.physorg.com/news171724009.html Medicine & Health Wed, 09 Sep 2009 14:40:05 EST news171724009 The good news: After a long, tight-lipped silence, the U.S. Federal Drug Administration tested lipsticks for lead -- a move that eco-nonprofit organizations like Campaign for Safe Cosmetics have been calling for years. After all, Campaign for Safe Cosmetics' 2007 study found lead in 61 percent of the 33 lipsticks tested -- despite the fact that lead wasn't listed as an ingredient in any of them! http://www.physorg.com/news171351650.html Medicine & Health Sat, 05 Sep 2009 06:41:19 EST news171351650 (AP) -- Some childhood lead poisonings in Maine last year came from an unusual source - lead dust tracked into the family car. http://www.physorg.com/news170007497.html Medicine & Health Thu, 20 Aug 2009 17:30:01 EST news170007497 (AP) -- China detained two factory officials after 1,300 children were poisoned by pollution from a manganese processing plant, state media said Thursday, days after emissions from a lead smelter in another province sickened hundreds. http://www.physorg.com/news169988794.html Medicine & Health Thu, 20 Aug 2009 12:07:06 EST news169988794 Although lead content in paint has been restricted in the United States since 1978, University of Cincinnati (UC) environmental health researchers say in major countries from three continents there is still widespread failure to acknowledge its danger and companies continue to sell consumer paints that contain dangerous levels of lead. http://www.physorg.com/news168611086.html Medicine & Health Tue, 04 Aug 2009 13:46:58 EST news168611086 Canada's Health Minister Leona Aglukkaq on Friday proposed banning six commonly-used chemicals in soft vinyl toys and child-care articles, as well as new strict limits for lead in products. http://www.physorg.com/news164642180.html Medicine & Health Fri, 19 Jun 2009 14:56:44 EST news164642180 (PhysOrg.com) -- In 2007, 416 children were reported to have elevated blood lead levels in Los Angeles County, a dramatic improvement from 10 years earlier, when fewer children were tested but 1,184 reports of children with elevated levels were made, researchers said. http://www.physorg.com/news162748118.html Medicine & Health Thu, 28 May 2009 16:49:26 EST news162748118 (PhysOrg.com) -- By sampling clouds -- and making their own -- researchers have shown for the first time a direct relation between lead in the sky and the formation of ice crystals that foster clouds. The results suggest that lead generated by human activities causes clouds to form at warmer temperatures and with less water. This could alter the pattern of both rain and snow in a warmer world. http://www.physorg.com/news159370515.html Space & Earth Sun, 19 Apr 2009 14:35:46 EST news159370515 In its quest to rid consumer products of a potent neurotoxin, an Oakland environmental group on Tuesday warned nearly 20 major retailers and manufacturers that they're selling women's purses, wallets, tote bags and other accessories with lead levels exceeding California state standards. http://www.physorg.com/news158494590.html Medicine & Health Thu, 09 Apr 2009 11:17:53 EST news158494590 Lead concentrations in the blood are associated with an increased risk of death from coronary heart diseases (CHD).
