Summary
Experiments on rats were undertaken to determine the toxicity of calcium, barium, zinc, cadmium, and lead stearates. The threshold levels of acute toxicity of studied substances were determined, the toxicity decreased from Cd to Ca (Cd>Ba>Zn>Pbs>Ca). The cumulation coefficients, determined at the threshold level were 0.2–0.3. Intratracheal administration of 50 mg of studied substances caused different toxic effect: Cd>Ba>Ca>Zn>Pb. The pathologic processes were presented mainly in the lungs. Observation revealed the marked skin resorptive effect of all the stearates. Recommendations as to the protection of workers are given. The factual data are presented in 3 tables and 5 figures.
