Exposure to phenoxy acids and their effect on worker’s 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/m³ and among clearing saw sprayers 0.06 mg/m³. 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 don’t cause sudden changes in health.

Silva Fennica Issue 64 includes presentations held in 1947 in the third professional development courses, arranged for foresters working in the public administration. The presentations focus on practical issues in forest management and administration, especially in regional level. The education was arranged by Forest Service. Two of the presentations were published in other publications than Silva Fennica.

This presentation describes application of labour legislation and occupational safety act in forest work.
