Volatilisation of pesticides from soil and plant surfaces

摘要

Volatilisation rates of five pesticides (parathion-methyl, endosulfan, lindane, trifluralin) applied in formulations wee determined from soil surfaces and French beans. Tests were performed in a wind tunnel under defined conditions (20 deg.C; air velocity 1 m/s; relative air humidity 40-60 /100). Volatilised substances in the air were trapped by passing a part of the whole air stream of the wind tunnel through polyurethane foam. Toluene extracts of the adsorbent were analyzed by gas chromatography.
