Document Summary
Ddt and other chlorinated hydrocarbons are so stable, have high solubility, and high toxicity, it makes them effective pesticides, as well as environmental nightmares. Often bio-accumulate in animal fat, leading to bio- magnification in predators like falcons. Grasshopper effect: substances evaporate from warm regions and precipitate in colder regions, accumulating in great concentrations in top predators up north. Ddt byproduct has been found to be able to enter a woman"s amniotic fluid, which can be dangerous to the developing baby even in small amounts. Pops like atrazine and alochlor are so dangerous and long-lasting, 127 countries agreed to ban them. The 12 most dangerous have been banned -pesticide can either have short term effects on human health or long term effects. Short term effects include poisoning and illness from high exposure doses. 3. 5- 5 million people suffer acute pesticide poisoning each year. Farmers who use pesticides are 8 times more likely to develop non-hodgkin"s lymphoma.
