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.
