| Abstract |
The exposure of twenty workers from three work sites to azinphos-methyl over an entire apple-thinning season was studied. Exposure potential was estimated by foliar residue measurements, and individual exposures were estimated by biological monitoring through urinary metabolites. Measurable azinphos-methyl residues were found on apple foliage at all sites throughout the six-week sampling period, indicating continuous exposure potential (median residue level of 0.5µg/cm2). Measurable levels of the urinary dialkylphosphate metabolite, DMTP, were found in virtually all urine samples, with concentrations differing significantly across the three sites (0.53, 0.29 and 0.90µg/ml), and with intraindividual variability much greater than interindividual differences. Group mean DMTP concentrations at each site fluctuated according to foliar residue levels. |
