Abstract. Background. An abnormally high content of heavy metals is an important predictor of the formation of a peculiar territorial elemental background in the components of urban ecosystems, which ultimately affects people’s health. A 25-year monitoring of the ecological state of the territory of the city of Amursk showed a high concentration of mercury in soil, water, liquid and solid biosubstrates of animals and humans. The goal is to study the balance of microelements in the “water –soil – plants – animals – man” ecosystem against the background of the impact of technogenic mercury pollution of the environment, due to the long-term absence of work on dismantling and demercurization of the territory of the Amursk Pulp and Cardboard Mill. Materials and methods. The analysis of impurities contained in the drinking water of centralized water supply (n = 25) was carried out; soil (n = 20); vegetable products of summer cottages (potatoes, carrots, cucumbers); human biosubstrates (hair, blood serum, n = 194); wool of mammals (n = 13). The content of elements: Cd, Hg, Pb, Ca, Fe, Co, Cu, Se, Zn, Mo, To, U, P (n = 12). Results. Analysis of the composition of water impurities from drinking sources of centralized and decentralized water supply in the territory of the cities of Amursk and Khabarovsk showed that, in 100 % of cases, the main factor influencing the sexual development of adolescents is high concentrations of P, Mn and low – Mo and Se. 65 % of boys and 80 % of girls are a low level of sexual development in Amursk. In foodstuffs of the daily ration of teenagers in the city of Amursk, the content of Hg hazardous to health was revealed. 68 % of adolescent boys and 80 % of girls in the city of Amursk have disharmonious physical development, mainly associated with a lack of body weight. Conclusions. In the studied urban ecosystem, contaminated with mercury over the past 25 years, a dysfunctional and maladaptive nature of indicators of somatic and reproductive health of the population, including the younger generation, was revealed.
