  1. Accidental Exposure to Pesticides in the Home Benjamin G. MuñizSouthern Adventist University

  2. History • Study in 1993 found that all nine homes in the evaluation were positive for pesticides indoors. Most commonly found were chlordane, chlorpyrifos, dieldrin, heptachlor, and pentachlorophenol (Lewis). • Organochlorinetermiticides used heavily in Hawai’i between mid-1940s-late 1980s on wooden buildings for pest control (Hawai’i) • A study in 1990 showed that normal indoor spraying of chlorpyrifos according to instructions would result in a dose at or above the level required for a toxicological response in infants (Fenske). • Survey from June 1989 to March 1990 showed that 97.8% of families in Missouri used pesticides in their home at least once per year (Davis)

  3. History contd. (Lewis)

  4. Regulation • In the US, the Environmental Protection Agency (EPA) is largely responsible for regulating the use of pesticides. • Chlordane banned by EPA in 1987 (Gandhi). • Chlorpyrifos banned for residential use in 2001 (EPA, 2002). • Dieldrin banned in 1985 except for specific uses (EPA, 2011a). • Heptachlor commercial sales banned in 1988 (EPA, 2014).

  5. Modern Day • Buildings treated with pesticides in the past may pose a present risk when being demolished (Hawai’i). • The Hawai’i State Department of Health released a factsheet regarding organochlorinetermiticides in land and buildings. Hazards posed, testing, preventing exposure, and history of common chemicals (Hawai’i). • In-home use of insect-killing chemicals was associated with a 70% increased risk of Parkinson disease, compared with no use of pesticide (Stephenson).

  6. Modern Day • Use of dangerous and illegal pesticides pose serious risk (EPA, 2011b). • Overuse or incorrect use of pesticides in the home can cause buildup of chemicals and lead to significant health problems (EPA, 2011b).

  7. Prevention • Avoid contact with areas that are known to be contaminated. • Plant grass to avoid soil erosion • Keep pets and small children away • Do not grow any edible plants nearby • Cover soil with a barrier (i.e., gravel, plastic, etc…) • When working near contaminated soil • Wash hands and face thoroughly • Do not track outside soil into home • Wear protective clothing (i.e., gloves, long sleeves, pants, etc…) (Hawai’i)

  8. Prevention contd. • Use of non-chemical pest controls. • Minimize need by preventing entry of pests. • Use pesticides approved for general use. • Strictly follow directions on label. • Buy only as much as you need. • Have sufficient ventilation when using indoors. • If you hire a company make sure they know what they are doing. (EPA, 2011b)

  9. Tying it in: Toxicology Today (Chapter 3) • Increased use of pesticides has led to the establishment of organizations tasked with controlling and regulating the use of chemicals. • These organizations cannot monitor and control everything. • Need for public awareness and education. • Toxic exposures due to lack of awareness of possible dangers. (Frank)
