Chemical Pollutants Lead to Fewer Female Births

High exposure to certain now-banned industrial chemicals may lead to fewer female births, a new study suggests.

The findings, reported in the journal Environmental Health, add to evidence that the two groups of related chemicals -- polybrominated biphenyls (PBBs) and polychlorinated biphenyls (PCBs) -- may affect human reproduction.

PBBs were once widely used as flame retardants in plastics, electronic and textiles, while PCBs were used in everything from appliances and fluorescent lighting to insulation and insecticides.

While the chemicals were banned in the 1970s as potential health hazards, they remain a public-health concern because they linger in the environment and accumulate in the fat of fish, mammals and birds.
