On the evaluation of living conditions and health status of residents in precast framed houses of the micro-disrtict Usolsky-2 (the city of Berezniki, the Perm region)

There are given results of instrumental studies of the air of 77 living rooms of precast framed houses of the microdistrict Usolsky, the Perm region, Russia. There were used materials emitting formaldehyde, phenol and other chemical impurities into the environment. In 90% of rooms levels offormaldehyde were shown to be systematically registered as by 1.5-10 times exceeding the hygienic average daily standard (0.01 mg/m³). Revealed concentrations create health risks to residents, which can be evaluated as unacceptable: lifelong cancerogenic risk made up about 2.8*10^-4, non-cancerogenic risk for respiratory organs disorders accounted of 8.7HI. Profound studies of residents ’ health showed the increased level of respiratory diseases in adults living for 1.5-3.0 years in observed houses. The group of the exposed people of the micro-district Usolsky was characterized by significantly higher consistent blood level of formaldehyde (3-7 times higher than in the comparison e group), and the presence of negative prenosological changes of several laboratory indices, including some of indices which testify both to general and specific sensitization to formaldehyde and the risk of the development ofproliferative processes. There are given suggestions concerning the guidelines to arrange primary and secondary preventive measures against potential health disorders of the residents of the micro-district.
