[Toxic effect of volatile products of thermooxidizing decomposition of conveyor belts].
Toxic effects of thermo-oxidizing decomposition products of conveying belts made of PVC and rubber have been tested. The resultant smokes were passed through a protective absorber. During 14-days' post-exposure observation, an increased activity of asparagine, aminotransferase and in some animal alanine aminotransferase was found. Moderately increased pathomorphological changes were found in lungs (emphysema, oedema interstitial and bronchogenic inflammations), along with slight degenerative changes in the liver and kidneys. In the peripheral blood, increased amounts of erythrocytes and leukocytes were found.
