A new study, led by Julia Taylor, a biologist at the University of Missouri, which used a new and more sensitive test for measuring BPA in mice and monkeys has found that the animals had "biologically active" amounts of the estrogen-like chemical in their blood – which suggests that the chenical is not completely removed by the liver, which is what had previously been thought.
This is the first time that comparisons hvae been made between mice and monkeys and although the method is controversial, extrapolations have been made for humans.
While some scientists maintain that these extraoploations are not valid, the results certainly raise concerns about how much of the chemical may actually be getting into the blood stream.
