The article presents the results of a hygienic study conducted in the territory of the Primorsky Territory to assess the primary incidence of digestive system organs among the children of the Primorsky Territory. For the study, data on the recorded primary incidence for 18 years were analyzed. Mapping of the primary morbidity was carried out, the attributive risk of digestive diseases was calculated. The territorial distribution of statistically significant average annual levels of primary morbidity showed that children are more likely to suffer from gastritis and duodenitis, gastric ulcer and duodenal ulcer in the northern part of the region, where the highest incidence rates are recorded — these are rural areas. with an unstable economic situation and areas of the eastern coast of Primorye with the most unfavorable climatic conditions. The results of calculating the attributive risk show that children (0–7 years old) living in rural areas of the Primorsky Territory belong to the risk group for diseases of the digestive system. The identified territories are the least economically developed, with the absence of powerful sources of anthropogenic pollution of the population's habitat. The results obtained in this work should be taken into account when choosing and substantiating the indicators of the regional information fund for social and hygienic monitoring, when developing effective primary prevention measures and making managerial decisions at the regional level in the field of health care for children and children. adolescents in the Primorsky Territory.
The article presents the results of a hygienic study to assess the chemical contamination of soils in residential areas of Primorsky Krai based on the results of social and hygienic monitoring from 2018 to 2020. The analysis of the actual concentrations of heavy metals in the soil was carried out for 7 chemical elements: lead, zinc, copper, nickel, cadmium, manganese, mercury in 12 administrative territories of the region. Soil safety control points are certified using a system of geoinformation technologies. It has been established that a feature of the administrative territories of the northern part of the region is a sharp predominance of natural sources of chemical pollution over all others. Contamination with toxic elements of soils in the southern part of the region, especially in places of compact residence of the population, is of a pronounced technogenic character. The leading mechanism for the accumulation of microelements in the soils of the cities of Primorsky Krai is their intake from the atmospheric air, heavily polluted by man-made emissions, the leading sources of which are motor vehicles, railroad and sea transport.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
