BPA linked to problems in factory workers

Scott Hensley, on NPR’s newly christened “Shots” health blog, points us to a five-year study of men who work in Chinese factories that make bisphenol A or use it to make other products.

The study found that “Men exposed to high levels of BPA on the job had a much greater chance of sexual problems than men who weren’t.” The factory workers are exposed to much higher levels of BPA than the average American, so research into how low a level of exposure might affect the human reproductive system must be done.

There are concerns that BPA is a threat to human health. Some studies have linked it to cancer, diabetes and developmental damage in animals, while other studies have not found such a link. Meanwhile, researchers have charged that studies showing a link were flawed. And, of course, the laboratory research is limited to animals. The controversy has extended to how the chemical has been covered in the media.
