Polymer materials have become widespread in the modern construction industry due to their cheapness and variety. With regard to their popularity at the present time there can appear the issues of their toxic and fire danger. The work has studied the samples of two floor synthetic building materials. The results of the determination of the fire hazard indicators of materials (combustibility, flammability, smoke ratio) showed their compliance with the current certificates. The authors have studied the properties of gaseous combustion products of samples by the method of thermal analysis and FTIR analysis. The results of chloride ions analysis according the formula of Maxwell-Mohr in thermolysis products indicate the toxicity of the materials studied.

The aim of study was the establish the influence of anti-freezing structure Ecotreck on organism of mammals. Experiments were made on rats and mice. The anti-freezing structure was diluted with the distilled water, then the received solutions entered intragastrically. Within 14 days were observed a condition of animals, changes were fixed. By results of researches it has been established that «Ekotreck» belong to moderately toxic substances.

The following paper discusses the quiestion of soil toxicity on technogenic zones of Orenburg. The work describes the main characteristics of soil covering of the city, soil biological analysis methods and the results of key zones soil biotesting.
