摘要：The residual fumigant technique involving the use of dichlorvos in the solid dispenser formulation employed in the study reported in this paper appears to offer no hazard to the occupants of houses treated at the rate of one dispenser per 500 cubic feet (14 m3) in so far as dichlorvos vapour toxicity is concerned. Even the maximum dosage rate tested (one dispenser per 60 cubic feet (1.7 m3) or 28 dispensers in a two-room house) did not produce observable effects on the occupants of the houses. This maximum rate far exceeds that necessary for malaria eradication operations, thereby affording an additional safety factor.
