[Data on establishing the MPEL for the dust of a polymineralic potassium ore in the air of a work area].
The article contains data on the norming principles for and the biologic action of polymineralic potassium dusts. The analysis and comparison of experimental and clinical data presented potassium ore as a substance characterized by low toxicity and weak fibrogenic action. In animal studies, the general toxic action of potassium aerosols exceeded the fibrogenic effects. MAC was suggested for working zone areas at 5 mg/m3 (3rd class of hazards).
