Pesticides and Health

Applicator sprays equipmentWhat is pesticide exposure?

Pesticides are substances designed to prevent, destroy, repel or mitigate pests. As of 2012, approximately 899 million pounds of conventional pesticides (e.g. insecticides, rodenticides, fungicides, herbicides, and fumigants) were used in United States agriculture (EPA 2017). 

What are potential adverse health effects of pesticide exposure?

Between 2007 and 2011, the rate of acute illness and injury among agricultural workers (18.6/1000,000) was estimated to be 37 times greater than the rate for nonagricultural workers (0.5/100,000) (Calvert et al. 2016). Skin absorption, inhalation, and ingestion are key routes of exposure to consider for occupational and residential settings. PNASH works to address pesticide exposure for those who are most vulnerable:

  • Pesticide handlers (mixers, loaders, and applicators) 
  • Children who have an enhanced susceptibility to the uptake and toxicity of pesticides

Overall, improved products, application practices, and case reporting have helped, but common illnesses and injuries still occur. Some of these common exposures happen through the off-target movement of pesticides (a.k.a. drift) or splashes to the eye. A growing body of evidence reveals that long-term exposure can lead to more serious health effects including neurological diseases and cancers.
