Newly published research shows that even very small doses of the Teflon chemical PFOA in drinking water pose a more serious threat to public health than previously thought. EWG’s report on the research, released today, shows that federal guidance on safe levels for PFOA is hundreds, even thousands of times too weak.
You can read the full report here. The report cites, among other things, this paper published this month by Harvard University’s Philippe Grandjean and University of Massachusetts at Lowell’s Richard Clapp, which concludes:
Perfluorinated alkyl substances have been in use for over sixty years. These highly stable substances were at first thought to be virtually inert and of low toxicity. Toxicity information slowly emerged on perfluorooctanoic acid and perfluorooctane sulfonate. More than thirty years ago, early studies reported immunotoxicity and carcinogenicity effects. The substances were discovered in blood samples from exposed workers, then in the general population and in community water supplies near U.S. manufacturing plants. Only recently has research publication on perfluorooctanoic acid and perfluorooctane sulfonate intensified. While the toxicology database is still far from complete, carcinogenicity and immunotoxicity now appear to be relevant risks at prevalent exposure levels. Existing drinking water limits are based on less complete evidence that was available before 2008 and may be more than 100-fold too high. As risk evaluations assume that untested effects do not require regulatory attention, the greatly underestimated health risks from perfluorooctanoic acid and perfluorooctane sulfonate illustrate the public health implications of assuming the safety of incompletely tested industrial chemicals.
Meanwhile, in federal court over in Ohio, there was another in a series of important rulings (see here and here) in advance of the mid-September and late-November start of trial in the first two of the thousands of personal injury cases pending against DuPont. This particular ruling, issued on Wednesday by Chief U.S. District Judge Edmund A. Sargus Jr., denied DuPont’s motion for summary judgment on the issue of punitive damages in the cases brought by Carla Marie Bartlett and John M. Wolf.
