Das YT, Taskar PK, Brown HD, Chattopadhyay SK: Exposure of professional pest control operator to dichlorvos (DDVP) and residue on house structures. Toxicol Lett. 1983 Jun;17(1-2):95-9.
Each of the 13 human volunteers carried out a 1-day urban pest control work in 4 homes using 10-14 aerosol cans (230-330 g dichlorvos (DDVP] and 18-22 pints of 0.5% emulsion spray (40-50 g DDVP). Average residue levels of 75.85 micrograms/ft2, 40.9 micrograms/ft2 were found on the applicator's back, chest and respirator filter, respectively. Residue on the house structure was 219.7 micrograms/ft2 on the first day, which fell to 50.9 micrograms/ft2 by the end of 5 days. Blood and urine analyses revealed no changes in various clinical parameters, including serum cholinesterase levels. |
