The Irkutsk province and the Republic of Buryatia which are a part of the Baikal Region (Siberia) were studied for environmental iodine balance. The water and local foodstuffs were found to show low iodine levels (they being 0.2 to 6.9 micrograms/l). In children, iodine deficiency was detected in 60-87% of the total number examined. There was a relationship between of the severity of neurological symptoms, the onset of thyroid diseases, general morbidity, physical development, iodine levels in the body. It is concluded that iodine deficiency has a great impact on the development of the regional pathology in children.

The contributors used the sensibilization threshold to establish MACs for the dust of the fodder yeast produced as a result of pulp and paper waste products' recycling. The product belongs to the group of substances with low toxicity. It does not produce local irritation and exhibits sensibilization properties in case of both epi- and intracutaneous introduction. The sensibilization threshold in repeated introductions of protein-containing dusts was registered at 4.1 mg/m3. In industrial conditions, the fodder yeast concentrations at the level of about 4 mg/m3 caused increased morbidity with temporary disability.
