||Evaluation of coumaphos exposure among tick eradication workers

||The objective of this study was to evaluate both the cholinesterase monitoring programme and newer field methods of determining coumaphos exposure among tick eradication workers. Methods used consisted of measuring blood cholinesterase, evaluating field testing methods, testing urine for chlorferon pre- and post-shift, personal air sampling, patch sampling of clothing and wipe sampling of hands for coumaphos. Fifteen workers had normal plasma cholinesterase and acetyl cholinesterase levels. No significant changes occurred pre- to post-shift. High correlation was found between plasma cholinesterase and acetyl cholinesterase levels. Chlorferon levels rose 4 to 6 hours after use. Airborne coumaphos was detected in only one sample, in a trace amount. The majority of patch and hand wipe samples detected coumaphos. It is concluded that dermal exposure to coumaphos results in significant increases in urinary metabolites of coumaphos.
