| Abstract: | Using HPLC, the authors had investigated the three metabolites of deltamethrin (DM) in the urine of spraymen and one suicide, namely: dibromovinyl-dimethylcyclopropane carboxylic acid (Br2A), 3-phenoxybenzyl-hydroxy-ethyl acetate (PHE) and 3-phenoxyl-benzoic acid (BA). Br2A was chosen as the biological monitoring parameter for DM exposed people, and the urine samples of one suicide and 11 farmers sprayed DM or DM plus methamidophos were examined for Br2A quantitatively which was detected in 8 of 11 sprayers and in the suicide case. |
