Abstract |
Over the past several years considerable attention has been paid to the health of farm laborers and other personnel exposed to pesticides. Many attempts have been made to use infrequent or periodic blood cholinesterase activity measurements as a means of estimating adverse exposure to anticholinesteratic materials--attempts that, for a variety of reasons often fail to detect any altered status of pesticide workers' health, However, field studies, despite some pitfalls in experimental design, have shown conclusively that farm laborers do suffer depressed levels of cholinesterase activity incurred during the course of their normal employment. |
