Worker Exposure and Volatilization Pattern of Cadusafos, Ethoprophos and Probenazole after Applying Granular Type Formulation on Soil in Greenhouse Park, Byung-Jun; Lee, Ji-Ho;
BACKGROUND: This study carried out to fate of pesticide and investigate worker exposure of pesticide in air after applying granular type pesticide formulation on soil in greenhouse for preventing farmer's pesticide intoxication. METHODS AND RESULTS: The recovery of pesticide, cadusafos, ethoprophos and probenazole on absorbent in air were ranged 80.9~121.1% in charcoal and 90.6~99.0% in XAD-4, respectively. Emission rate of in lysimeter was higher 3~5 times than that of pesticides from topsoil not added water at plot after applying a mixture of granular formulation and soil. The ethoprophos concentration in air, 50 cm high from soil surface at greenhouse, was reached the highest 186.4 within 13 hours and were ranged 17.8~186.4 during 46 hours after applying granular formulation at dose rate 150 g a.i./245 . The cadusafos concentration in air at greenhouse was reached the highest 37.3 within 39 hours and were ranged 10.0~37.3 during 46 hours after applying granular formulation at dose rate 180 g a.i./245 . The probenazole concentration in air at greenhouse was reached the highest 1.45 within 37 hours and were ranged 0.23~1.45 during 46 hours after applying granular formulation at dose rate 144 g a.i./245 . CONCLUSION(s): The result of the reentry interval study demonstrated that reentry intervals for ethoprophos and cadusafos are longer than 48 hours.
