Pregnant women should not paint boats or drink water that touched PVC!

Exposing pregnant mice to low doses of the chemical tributyltin -- which is used in marine hull paint and PVC plastic -- can lead to obesity for multiple generations without subsequent exposure, a UC Irvine study has found.

After exposing pregnant mice to TBT in concentrations similar to those found in the environment, researchers saw increased body fat, liver fat and fat-specific gene expression in their "children," "grandchildren" and "great-grandchildren" -- none of which had been exposed to the chemical.

These findings suggest that early-life exposure to endocrine-disrupting compounds such as TBT can have permanent effects of fat accumulation without further exposure.

Human exposure to TBT can occur through PVC plastic particles in dust and via leaching of the chemical and other related organotin compounds from PVC pipes and containers.

Significant levels of TBT have been reported in house dust -- which is particularly relevant for young children who may spend significant time on floors and carpets. Some people are exposed by ingesting seafood contaminated with TBT, which has been used in marine hull paint and is pervasive in the environment. [emphasis mine]

Fetal Exposure to PVC Plastic Chemical Linked to Obesity in Offspring

I wonder if PVC furniture is an obesity hazard.
