Exposure to phenoxy acids and their effect on workerâs health were studied among 35 exposed forest workers. The control group was 47 non-exposed loggers. The both groups were medically examined before and after their working period including such laboratory analyses as B-differential count, B-thrombocytes. In addition, the exposure to eight ULV sprayers and two clearing saw sprayers were measured in breathing zone. The mean of phenoxy acid concentrations in urine among all the exposed workers after the working period was 6.5 μmol/l being significantly below the hygienic limit value (14 μmol/l). The mean concentrations of ULV sprayer workers was 7.3 μmol/l and of clearing saw sprayer workers 2.7 μmol/l. The mean of air concentrations among ULV sprayers was 0.23 mg/m and among clearing saw sprayers 0.06 mg/m. No statistically significant differences were noticed in the hematologic parameters and in the enzyme activities of the liver, kidney and muscles between the exposed and control groups before or after the working period. So, it seems that these low exposure levels donât cause sudden changes in health.33 |
