The dating scene for straight, single women is already fraught with “modelizers” and “freaks,” at least according to the ladies of Sex and the City, but it looks like the pool of eligible bachelors may be about to get smaller, according to a recent study published in Environmental Health that found women exposed to high levels of polychlorinated biphenyls, or PCBs, are significantly less likely to give birth to boys.
Though environmental PCBs levels have decreased since the ban took effect in 1976, their toxic tale of woe isn’t over yet. Because industry can no longer make PCBs, it has since created similar compounds that often show up in flame retardants. The production of these chemicals is rapidly increasing, the study’s lead author Irva Hertz-Picciotto told the New York Times. One especially worrisome compound is polybrominated diphenyl ethers, or PBDEs: They’re structurally very similar to PCBs, extremely persistent in the environment, and can bioaccumulate. Adding these toxic chemicals to items like drapes, carpets, furniture upholstery and the plastic casings of electronics makes them difficult to burn, according to the Michigan Network for Children’s Environmental Health, an environmental group advocating the ban of certain types of PBDEs.
Currently, 10 states regulate use of two of the three types of PDBEs (penta- and octa-BDE). And Dell, Apple, Samsung and many other electronics companies already do or will soon meet fire safety standards without using the third type, deca-BDE. Additionally, mattress companies Sealy, Simmons and Serta do not use deca-BDE in their products, and IKEA sells only PBDE-free office furniture.
Despite these actions, PBDE levels are increasing, according to study co-author Todd Jusko, and widespread PBDE contamination has been reported in human beings, wildlife and foods. While the federal government drags its feet on banning PBDEs, consumers can minimize their exposure. The Environmental Working Group provides a list of PBDE-free manufacturers and products. And The Green Guide’s online shopper’s card offers recommendations like broiling and trimming the fat from meat and fish as well as drinking skim milk, which is PBDE- and dioxin-free, to maintain a more PBDE-free life.
