Abstract
For a simulation of toxic effect of silicon nitride powders (in different dispersion state) on human organism, the rates of conversion and mechanisms of interaction with physiological Ringer-Lock solution, gastric juice, blood serum and inorganic media with the same pH were studied. for the alkali and neutral biochemical media, the mechanism of bioinorganic catalysis was established, the Ca2+— ions play the role of catalyst. The results of study were confirmed by toxic tests using a priming of white rats with Si3N4 powders and the further analysis of their blood indexes as well as morphological state of lungs and liver after 1, 3 and 6 months.
