TPS 623: Exposures to pesticides, Johan Friso Foyer, Floor 1, August 26, 2019, 3:00 PM - 4:30 PM Background: Children are particularly vulnerable to adverse health effects from pesticide exposures. This research aimed to evaluate children exposed to pesticides, home indoor wipe samples and home soil samples for both conventional and organic farmers. Methods: Twenty-three children hands wipe samples (age 1-6 years) were collected in 2017 and only three children hands wipe samples were collected in 2018. Overall 19 and 35 wipe samples of indoor home surfaces were collected in 2017 and 2018, respectively. Twenty-three and 35 home soil samples were collected in 2017 and 2018. Indoor surface samples were collected with a 10x10cm cotton pad moistened with 70% ethanol from a 100 sq cm grid. Palmar hand wipes of children were collected after parental assent using the same pad as surface wipes, and composite. About 1 kg of soil were collected at a depth of 0-10 cm from several places around the house. All samples were analyzed for 16 organochlorines, 10 organophosphates, 4 pyrethroid, 6 carbamates, fipronyl, paraquat, glyphosate and alachlor pesticides using standard AOAC analytical protocols. Results: For conventional farmers, children hand wipe samples detected cypermethrin, fipronyl in 2017 and cabofuran in 2018. For organic farmers, hand wipe samples detected mainly fipronyl and cypermethrin pesticides in 2017. Home indoor surface wipe samples of conventional farmers detected cypermethrin, fipronyl, amethrin and carbofuran. For organic farmers, home indoor surface wipe samples detected cypermethrin, fipronyl, permethrin and bifentrin. Home soil samples found paraquat dichloride, chlorpyrifos ethyl, carbaryl, AMPA, ametrin, glyphosate, atrazine, metribuzine, metalaxyl, carbofuran, etc.in conventional farmers. For organic farmers, the home soil detected was paraquat dichloride, AMPA and profenophos. Conclusion: Children may expose to pesticides from pesticides using in homes for both conventional and organic farmers. Children may also expose to pesticide in home soil from playing on the ground.
