К вопросу изучения химического загрязнения воздушной среды закрытых помещений детских учреждений городов Иркутской области

The qualitative and quantitative chemical indoor air characteristics in the childrens establishments in the towns of Irkutsk Region are given in this paper. A total quantitative level of chemical pollutions with some compounds in the buildings was found to be higher than the atmospheric air pollution level up to 2 times and more (formaldehyde, suspended substances). The data on formaldehyde content in the children's urine samples of the towns and the rural areas studied of Irkutsk Region are presented too. The formaldehyde excretion in the children living in the industrial centres of Irkutsk Region was noted to be higher than in the children living in the rural areasSo, the average group levels of formaldegyde in the towns with the enterprises of Chemical Industry (t. Angarsk and t. Sayansk) were (124,30 ± 8,12) and (117,20 ± 12,92) nmol/dm3, respectively, which were signifi cantly higher than the levels in the regions such as Zalari (96,40 ± 10,56) nmol/dm3 and Zhigalovo (73,70 ± 17,17 nmol/dm3).
