[Cytoenzymatic examinations of peripheral blood granulocytes in overhaul workers of the chemical plant "Organika-Jaworzno" at Jaworzno].

In order to evaluate the functions of granulocytes, cytochemical reactions to alkaline and acid phosphatases, beta-glucuronidase, myeloperoxidase and catalase were performed in leukocyte concentrate smears for 45 overhaul workers of a chemical plant producing pesticides. As compared to the control group of 24 unexposed healthy individuals living in the plant area, the alkaline phosphatase and catalase reactions were weaker; the leukocyte count was slightly elevated; the differential white blood cell count did not show any significant changes, only the percentage of monocytes was slightly reduced. The results of our studies can testify a slight impairment of leukocyte function in workers exposed to chemical pesticides.
