Environmental Estrogens
Environmental Estrogens
Environmental Estrogens can either be natural or due to man-made chemicals. Estrogen Chemicals can be found in: * Pharmaceuticals (hormone therapy drugs, birth control pills) * Pesticides (insecticides, fungicides)

* Plastic linked products (Bisphenol A, phthalates)
* Heavy metals (Mercury, Lead)
* Household Products (detergents)
Environmental Estrogens are manufactured for a purpose such as contraceptives and pesticides. Environmental Estrogens can be found in Rivers, Aquifers, Farms, Orchards, and Sprayed on Gardens and Lawns or in the air as vapor or smoke. Biologists and Toxicologists found out about the feminization of Male fish by looking at eggs of fish and seeing that a certain type had no fertilized eggs. They then went and found that the male fish were producing a protein named vitellogenin which they found is used in the process of making egg yolks. The Fish had changed in the inside most likely due to Bisphenol A. A Canadian Study found that women flush too many birth control and hormone therapy pills down the toilet, and that wastewater runoff containing these products are polluting the waters.
