I will start off with a general introduction to the meaning of the pesticide, Malathion which is a man –made organophosphate pesticide that is yellow in color and produces a skunk-like odor. This particular pesticide is used to control mosquitos that carry the sometimes deadly central nervous virus called West Nile. This pesticide is also used by farmers and the like to control the population of bugs that eat vegetables, fruits, and can be very destructive to landscaping such as small bushes and plants. This pesticide can also be found in other types of insect chemicals used to control fleas and ants. On humans, this product is an effective chemical used to treat lice.
When spraying occurs, this will be a smoky mist that will be done in the early evening when most are settling down indoors for the night. Even if people were still outside, the risks of exposure are not as great as one would think. Once sprayed, the effects would diminish within 30 minutes. On exposure to water, Malathion does break down rapidly it does not pose a threat to ground water, even if it is in the topsoil.
Hazard identification of Malathion has been used in Human trials to determine levels of toxicity as noted here in Human Studies: Results from human studies are presented for information purposes only. The U.S. EPA presently does not use data from human studies in its risk assessments (EPA has asked the National Academy of Sciences to make “recommendations regarding the particular factors and criteria EPA should consider to determine the potential acceptability ...”) of data from human studies. “... During the Academy's consideration of the issues and until a policy is in place, the Agency will not consider or rely on any such human studies in its regulatory decision making, whether previously or newly submitted. ...” – Quotes from:...
