| Abstract: | Principal haematological tests in peripheral blood, non-specific phosphatases and myeloperoxidase in granulocytes were determined in a group of 89 males occupationally exposed to the elementary mercury during manufacture of chlorine. Examined males were employed for 2-26 years. Blood mercury levels did not exceed 50 micrograms per l-1. The obtained results indicate that low concentrations of the elementary mercury in the environment do not produce significant abnormalities in both quantitative and qualitative picture of peripheral blood but markedly inhibit neutrophil non-specific phosphatases activity. |
