摘要： Operator exposure was evaluated to find out any possible risk during fenthion application in paddy. Hand exposure during mixing/loading was 0.04-33.06 mg, whereas those for spraying were 20.3-288.3 mg. Highest exposure was observed on legs (54%) followed by hand (28%). Inhalation exposure accounted for only 0.001-0.2% of dermal exposure. High variations of exposure levels were observed between repetitions and operators, indicating that lager number of repetitions are strictly required to establish comprehensive exposure database and predicting models. Margin of safety indicated that application works were safe when extreme cases were not considered.
