production in the United States - and less availability of DDT for the .
developing world. The results were disastrous: at least 1-2 million people .
continue to die from malaria each year, 30-60 million or more lives needlessly .
lost since the ban took effect." (Seavey 2003). .
Yet another set of chlorinated hydrocarbons not as widely known as DDT are .
chlorinated naphthalenes. Dieldrin, aldrin, and endrin were once widely used .
chemicals for pest control, but dieldrin and aldrin have been banned because of .
their toxicity being five to forty times more toxic that DDT depending on the .
method of intoxication. However, endrin is still in use today is by far the .
most toxic of all of the chlorinated napthalenes. "The U.S. Environmental .
Protection Agency ranks Endrin in the top 10 percent of the most toxic .
chemicals for human health." (EMS 2003). If not treated in a timely manner, exposure to .
endrin has the ability to kill in 2-12 hours. .
DDT, although considered to be very detrimental to the environment and mammals, because of its longevity has taken the spotlight away from many other more .
dangerous chemicals. DDT has proven time and again that it has the ability to .
save lives, but other chemical such as chlorinated napthalenes have the ability .
to take lives with little benefit to their intended use. .
A second group of pesticides that I would like to discuss are organic .
phosphates. Exposure to organic phosphates has serious risks for any type of .
animal including humans. Organic phosphates destroy enzymes and target the .
central nervous systems in organisms causing spasms, convulsions, and death. .
Organic pesticides are far more dangerous and toxic than DDT and the other .
chlorinated hydrocarbons are still being used to this day.
The first of the organic phosphates is Parathion. Parathion is one of the most .
highly used of the organic phosphates, yet it has a high rate of death when .
