There is a pressing issue related to combined oral introduction of heavy metals into a human body with drinking water and food products. It is caused by food products contamination, very high probability that metals migrate into water and plants from soils, ambient air, etc. The research goal was to hygienically assess combined oral introduction of heavy metals with drinking water and food products with subsequent population health risks assessment. The authors analyzed long-term data on structure and volumes of food products consumption and assessed population exposure under combined oral introduction of heavy metals (mercury, cadmium, arsenic, and lead) contained in drinking water and food products. Data were obtained from a regional information social-hygienic monitoring database and a regional office of the Federal Statistics Service. Both regional products and products delivered from other regions (or countries) were analyzed. It was detected that population in the region consumed food products per 1 person a year in a quantity which was by 93 kg higher than on average in the country. Calculated concentrations of the examined substances in food products and drinking water corresponded to hygienic standards. Dairy products had the first rank place as regards a contribution made into the overall exposure to lead, cadmium, and arsenic. The second and the third place belonged to vegetables and melons and grocery respectively. The first rank place as per a contribution made into the overall exposure to mercury belonged to vegetables and melons; the second place, to grocery; the third place, to dairy products. Non-carcinogenic risk assessment revealed that hazard quotients related to heavy metals contents in food products and drinking water were within acceptable risks limits. Total carcinogenic risk (TCR) was unacceptable (1.5Е-03.). A number of additional oncologic diseases in the region could reach 557 cases (during 70 years) under the worst scenario.
The ranking of municipal formations of the Orenburg region on the incidence of malignant neoplasms of the colon, rectosigmoidal junction and rectum, and the level of carcinogens in food and drinking water has been ranked. Based on average concentrations, the total coefficients of carcinogens supplied with drinking water from centralized water supply and food products were calculated. Priority carcinogens have been identified in drinking water and food products that affect the occurrence of colon cancer, rectosigmoidal connective and rectum, as well as the risk area, with an increased incidence of colon cancer, rectosigmoid and rectal cancer caused by a carcinogenic load in drinking water and food Products.
The purpose of the research study was the identification and quantitative assessment of ambient air pollution with risk assessment to public health on the territories of the Orenburg region, bordering the Republic of Kazakhstan. A hygienic assessment of thirteen border municipalities of the Orenburg region was carried out in the paper. We conducted an ambient air analysis for 23 substances, which are under long-term dynamic observation and a non-carcinogenic risk to public health was calculated. It was established that the Western and Central parts of the border territories differing in the qualitative composition of pollutants have the highest level of anthropogenic air pollution. At the same time, the qualitative composition of pollutants in the Western part of the border territory is mainly represented by substances that originate from gas and oil refining facilities. Priority pollutants in the Central part of the border territory are substances that originate from non-ferrous and ferrous metallurgy facilities. Climatic data analysis in the study territory has shown that conditions for the transboundary transfer of atmospheric pollution, both from Kazakhstan and from the Russian Federation can be created with certain meteorological parameters. Non-carcinogenic health risk analysis showed the probability of adverse effects development on organs and systems, as well as the probability of malignant neoplasms occurrence in the population living on the border territories. The study justifies and confirms the need to develop a system for monitoring and to assess the probability for transboundary transport of atmospheric pollution, as well as practical recommendations and preventive measures to reduce anthropogenic load.
