Paraquat: a Review of Worker Exposure in Normal Usage**

摘要

The likely worker exposure to paraquat in agricultural practice, using correct procedures, is reviewed with particular reference to the possibilities of oral, dermal and inhalational absorption. The available evidence indicates that at recommended dilution rates systemic effects do not occur. Local effects on skin and mucous membranes may occur as the result of the delayed caustic effects of this herbicide, but experience has shown that paraquat is unlikely to give rise to serious problems when properly used.
