[Main results of experimental studies on the toxicology of inhibitors of atmospheric corrosion of metals].

Basing on experimental toxicity research it was established that, out of 50 atmosphere metal corrosion inhibitors, some 14 per cent were found extremely hazardous, 42 per cent--of high level hazardous, 33 percent--of moderate and 11 per cent--of low hazardous. Relationships were identified between the structure of polymethylene amine salts, azole compounds and carbonic acid, and the way they influence human organism. It was also found that inhibitors exercise a polytropic action in man, the toxicity action being concentrated on oxidation processes, and the inhibitors specifically influence protein, carbohydrate and phosphoric metabolisms, as well as the red blood system. This causes functional and structural disorders of CNS and in the parenchymal organs. Inhibitors are characterized by local and skin-resorption actions, their degree and specific features depending on their chemical structures. 22 MACs of working zone inhibitors are proposed, along with early diagnostic tests and preventive measures.
