ABSTRACT
Total amount of natural and antropogenous mercury in ambient air of Blagoveshensk city, living area air, industrial spaces air exceeds the background values, but does not influence the level of bronchopulmonary diseases, gastro-intestinal and gall pathways disorders in children, adolescents and adults. Occupational intoxications and occupational diseases were not revealed in specialized chemical laboratory staffers.

Analysis of the 1991-2006 statistical data of the Amur Region has indicated that the prevalence of tuberculosis does not depend on the level of ambient air pollution, the total amount of mercury-containing pesticides introduced into the plough-lands, and the environmental emission of metallic mercury at gold mining. The established set and the level and ratio of major mineral and trace elements in the blood of healthy individuals are suggestive of their adaptation to the specific geochemical environment. The excess and deficiency of major mineral and trace elements in the blood of patients with pulmonary tuberculosis result from the occurring pathomorphological, pathophysiological, metabolic, and other disorders that hamper the excretion of toxicants.

Rats were exposed to a constant magnetic field of 26268A/m. Depending on the exposure time, the thyroid gland showed changes in the follicular epithelium height, content of ribonucleoproteins and PAS-positive substance, activity of adenylate cyclase, whereas blood serum exhibited changes in the concentration of thyroid hormones and no changes in the content of thyrotropic hormone.
