Biological Monitoring of the Exposure Level of Organophosphorus and Pyrethroid Pesticides in Floriculture Workers and Florists

Abstract This study was performed to evaluate the exposure level of organophosphorus and pyrethroidpesticide to floriculture workers and florists. The urinary dialkylphosphates, metabolites of organophosphorusinsecticides, including dimethylphosphate (DMP), diethylphosphate (DEP), dimethylthiophosphate (DMTP),diethylthiophosphate(DETP) and pyrethroids of metabolites, cis/trans DCCA, DBCA, and 3-PBA wereanalysed to evaluate the exposure of organophosphorus and pyrethroid pesticide to floriculture workers andflorists. The concentration of DMP is highest in floriculture workers. but the concentration of DETP ishighest in retail florist. The concentration of 3-PBA is highest in floriculture workers. The amount oforganophosphorus and pyrethroid pesticide expusure is highest in flower workers, wholesale florist and retailflorists are followed. The management for reducing pesticide exposure to floriculture workers and wholesaleflorist is required.Key words dialkylphosphate, GC/MSD, orgnophosphate insecticides, pyrethroids insecticides, urine
