The state of health of the population living in the zone of influence of chemical production of Kazan is studied. The indicators of health of the population in the zone of influence of the enterprise are analyzed. The assessment of health risk from the effects of pollutant atmospheres-tion of air in accordance with the Manual R 2.1.10.1920–04. The priority polluting substances and priority groups of diseases characteristic for the studied territory are allocated: diseases of blood and hematopoiesis and respiratory organs. The priority list includes 40 substances, including 19 carcinogens. When ranked by the contribution to the total emissions of all pollution-complementary substances are distributed by hazard class. The greatest contribution to the total emissions is made by substances of the 3rd and 4th hazard classes (69.0 %), that is, moderately and low-hazard. For priority pollutants (ethylene, carbon oxide, benzene, ethylene oxide, nitrogen dioxide) contained in the emissions of the studied production of organic synthesis, similar organs and systems are characterized, which suggests its significant contribution to the formation of health indicators under the influence of this list of emissions. On the basis of the obtained values of risks, the necessity of increasing the boundaries of the sanitary protection zone of the plant was confirmed, a program of laboratory control of air pollutants at the stationary station was developed.
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.
