How does bisphenol A get into invertebrates?
« on: 22/05/2015 10:49:31 »

I wonder how bisphenol A enters into invertebrates (earthworms) cell? Is that way of entering different in vertebrates?
Is there any mechanism in vertebrates that can export BPA outside the cell?
Is there any study that has proven xenobitoic interaction with receptors in invertebrates?

Thank you!

It has been found that shop assistants working with BPA-coated receipts show elevated levels of BPA in the blood after a day at work. This suggests that it can be absorbed directly through the skin.

I am guessing that an earthworm's soft, moist skin is less resistant than a human's dry skin, which is covered with a hard layer of dead skin cells?

Although it is not very water-soluble, and it breaks down after a few weeks in the soil, BPA can slowly leach out of plastic bottles. we have been dumping plastics into the environment for many decades, so I guess there could be biologically-significant levels in the soil and in streams?

BPA acts like a hormone, and our bodies have very sensitive receptors for hormones.
