This Month in EHP
By Eddy Ball
The June 2009 issue of Environmental Health Perspectives (http://www.ehponline.org/) is now available online, with a feature story on the growing problem of antibiotic resistance and the emergence of new strains of bacteria. The journal also takes a critical look at the aquaculture industry's impact on the environment as increasing demand for fish leads to the proliferation of fish farms.
A new study surveys modern environmental health hazards in Africa, and a team of researchers led by NIEHS scientist Retha Newbold reports on ovarian pathology in offspring of mice exposed to bisphenol A (BPA) during gestation. In a study of rats exposed to low levels of organophosphate insecticides, researchers discover a possible link between diet and neurodevelopment effects of pesticide exposure. Other new studies address semen quality in young Danish men and perfluoroalkyl acids exposure, the effects of wildfire particulate matter on lung function in mice, and the association between specific pesticides with PCBs and childhood leukemia.
