The biggest problem with most herbicides is that we consider them safe because we see them all around us and do not question them. Homeowners use them on lawns and gardens, and farmers use them to produce crops we consume regularly. Since you cannot see herbicides, it is difficult to know where danger exists. Other problems include run-off into waterways, or animal consumption.
Recently, studies linked Roundup to placental cell sensitivity and Professor Gilles-Eric Seralini of France's University of Caen found that this sensitivity occurs at concentrations lower than agricultural use. Roundup comes in two varieties, the type used by farmers in high volume application on fields, and the other for home use by gardeners. Both are extremely popular, and usually considered harmless to people and animals. Exposure to Roundup can cause a higher number of spontaneous abortions in pregnant women. The same study shows that even weaker concentrations than those affecting the placenta cause endocrinal disturbances in humans.
Herbicides that contain 2, 4-D (Weed B Gone Max, Plant Guard, and others) are also linked to several forms of cancer such as non-Hodgkin's Lymphoma. A study at Orebro Medical Center and Lund University in Sweden found common herbicides used in agriculture increase the risk of these types of cancer as much as 2.7 times. These herbicides are also toxic to aquatic life. Never use a commercial herbicide 2, 4-D where water runoff occurs.
Broad Spectrum Herbicides
This type of chemicals kills weeds in grass or fields. It is common on home lawns and people come in close contact with it regularly. The studies done on the chemicals to determine its impact revolve around consumption. Companies such as ChemLawn claim that their products are safe and a child would need to consume 10 cups of grass to have adverse effects. However, the problem with these types of chemicals is more through absorption in the skin, most often by children playing on the ground.
