A new study has found that many common pesticides block male hormones and may be a contributor to the decline in male reproductive health. This is one of the only recent studies to focus on human exposure to new chemicals. The majority of studies to this point have been about pesticides that are no longer used. The study found that 30 of the 37 pesticides tested were anti-androgenic and may play a significant role in blocking normal hormone activity.
Pesticides are widely used to protect crops from insects, diseases and weeds. The purpose of pesticide use it to keep people safe by preventing crops from being contaminated. Since agriculture is an essential part of maintaining our food supply we have to be careful of the effect that pesticides have on humans.
Human exposure to pesticides often occurs when the chemicals leach into groundwater after a heavy rain. Once a chemical has made it into the water supply it can eventually end up in our public water system. Pesticides in public water are most likely to be found in more agricultural areas. Hopefully as we learn more about the health risk posed by pesticides we will be more responsible about what chemicals we are exposed to. In the meantime it is always a good idea to have your water tested to find out exactly what contaminants are in your local water supply.
