[Brief review of documents with data on the toxicity and hazards of chemical substances developed in various countries].

Nowadays various information documents on toxicity and danger of chemical substances exist, i. e., toxicologic certificates, data profiles, trade certificates, etc. An attempt has been made to analyze 15 available data lists used in various countries for the description of noxious and hazardous characteristics of chemicals. The indices on toxicity and danger of chemicals enumerated in the lists are grouped by 9 main categories. The degree of detailed description of the data presented is determined by the aim of the document. The results thus obtained can be used in the further work aimed at the improvement and unification of the forms providing the data on toxicity and danger of the chemicals.
