Human Exposure: 52-74ng/kg/day
How does the endocrine system work?
BPA increased the level of hormone receptors produced by a prostate gland cell
Some dosages of BPA were environmentally relevant
An increase in cell receptors fuels growth of the cell Cells can proliferate out of control, resulting in
cancerous tumor cells.
Conclusions BPA is harmful in lower doses BPA can leech into food/beverages at
relevant levels BPA exposure increases risk of cancer
