U.S. EPA says it is OK for humans to take in up to 50 micrograms of BPA per kilogram of body weight each day. The new study, published in the journal Environmental Health Perspectives, suggests that we are exposed to at least eight times that amount every day.

“Our data raise grave concern that regulatory agencies have grossly underestimated current human exposure levels,” states the study.

The study also gives the first experimental support that some BPA is likely cleared at similar rates in mice, monkeys and humans, making it possible to extrapolate health studies in mice to humans.

Despite decades of research, questions about BPA have lingered and recently become politicized. Sen. Dianne Feinstein (D-Calif.) hopes to add an amendment to the “FDA Food Safety Modernization Act,” currently under consideration in the Senate, banning the chemical from children’s food and drink packaging. Republicans and industry representatives have been averse, saying that research has not shown conclusively that the chemical is harmful.

Hormones are essential during development and can determine, among other things, a child’s gender. BPA, since it mimics estrogen, is an “endocrine disrupter,” according to Thomas Zoeller, a biology professor at the University of Massachusetts, Amherst. And amazingly, BPA has the ability to bind to not one, but three receptors — the estrogen, the male hormone and the thyroid hormone receptors, Zoeller said.

India is currently the 11th-largest passenger car market, and in the next five years it will become the seventh-largest, according to Ernst & Young. By 2030, the nation is expected to be the third-biggest after China and the United States. The country adds 1.5 million cars every year to its roads, and experts say sales could explode, a move that could greatly inflate India’s greenhouse gas emissions.

“India is an underpenetrated market,” said Kapil Arora, a partner in the automotive practice at Ernst & Young. “It has nine cars per 1,000 people. In the United States, there are about 800 cars per 1,000 people.”
