Have you ever been driving down the road with the windows open going past a golf course or a field and then you get a strange smell? A chemical type of odor? Or go walking in the country and notice a large area, usually a field, all brown with dead grass. And next to it, alive green grasses and shrubs? Chances are you smell a herbicide being used or you are seeing what it can do to vegetation.
Then you start to wonder. Are those chemicals getting into the water table? Is wildlife eating the “treated” vegetation and insects tainted with the chemicals? Or maybe we are taking in the toxins and not even realizing it. It could possibly be in the foods we eat, the air we are breathing everyday or the water that we are drinking.
DDT is a colorless contact insecticide that is very toxic. It became banned in the early 1970’s. Gaylord Nelson, a great environmentalist while in office in the state of Wisconsin diliengtly worked to get DDT banned in Wisconsin.
DDT even though restricted is still used in Mexico to control malaria. The National Institute of Public Health of Cuernavaca, Morelos, Mexico concluded from a study that the use of DDT has been linked to breast cancer in Mexico. In another study done by the University of Michigan, it was found that chemical factory workers that made DDT also had a high risk of pancreatic cancer from the overexposure of DDT. Unfortunately, DDT is still being manufactured and used in tropical areas for malaria control.
Below are some of the herbicides used today. This is not a complete listing of all of the herbicides on the market. The short term and long term side effects is based that the Maximum Contaminant Level (MCL) goes over a certain marker for parts per billion (ppb) in the water. For example Simazine is 4 ppb or 4 parts per billion in drinking water.
Simazine:
Common Trade names: Herbazine, Herbex, Surflan
General Uses: Corn Crops, Christmas Trees
Amount Used Annually: 4.8 billion pounds estimated in 1985
Short Term health Effects: weight loss, changes in blood
Long Term Health Effects: tremors, damage to testes, kidneys, liver, thyroid, cancer
Ground Water Implications: It may leach to ground water. It can last from a few months to years.

Taking in consideration that municipalities have their water tested on a regular basis, this does not take into account the urban and rural areas with its own private wells. Generally that is where a lot of herbicide is used for crops. Also in the city locations one has to take in account the air you breathe.
