【 摘 要 】

The residents of modern megacities are exposed to environmental risks arising both directly in the urban environment and their own dwellings. Modern polymeric building materials are the sources of toxic substances release into the air that have a significant impact on the population health. The objective of the work is the ecological and hygienic study of the air in the apartments of Irkutsk after repair work on the roof and walls insulation using the technology of pouring and calculation of the potential environmental risk for the residents. The object of the research was the indoor air in one of the houses in Irkutsk tested for formaldehyde and other toxic substances. After putting the house into operation, some defects were found - the freezing of the walls of the building attic part. During the repair work, the mansard part of the building was heat-insulated by the pouring method using the composite material "Poroplast CF 02". High concentrations of formaldehyde and styrene were detected in the apartments exceeding the MPC in 4-8 times. The hazard ratio for inhalation exposure to harmful substances exceeds the safety level by 10 times. Consequently, there is a high probability of obtaining acute and chronic poisoning and developing cancer.
