[Hygienic evaluation of the effects of vibration and arsenic in miners engaged in extraction of arsenic-containing ore].

Hygienic evaluation covered work conditions on 4 gold mines including 3 ones for gold and arsenic and one "arsenic-free". The mines demonstrated similar occupational factors, but differed in arsenic content of the ore extracted and therefore in arsenic concentrations in air of the workplaces. Miners engaged into extraction of the arsenic-containing ore, especially those exposed to vibration and arsenic concentrations over the MAC, manifest extensive arsenic accumulation in the hair and excretion with the urine, higher morbidity with transitory disablement, more prevalent vibration disease and mortality with malignancies. Vibration disease in those subject has more severe course, serious vegetative and sensory polyneuropathy, that is believed to result from co-action of vibration and arsenic.
