Study of the impact of atmospheric pollutants on morbidity in pregnancy in the Belgorod region


Full Text:


The performed study demonstrates a significant influence of pollutants of the air pool on the health of pregnant women in the Belgorod region. In areas with a high morbidity rate in pregnancy emissions of pollutants were found to be 3,25-995 times higher than in areas with low morbidity rate. The range of the variability of exceedances depends on the grouping of emissions, emissions of solid and gaseous pollutants, total emissions of pollutants, as well on substances - carbon monoxide, nitrogen oxide, sulfur dioxide, benzene, ammonia, xylene, acetone, toluene, manganese, fluorine, vanadium pentoxide, calcium oxide, hydrogen chloride, sulfuric acid, carbon black, hydrogen sulfide, chlorine, methane, phenol, butyl acetate, ethyl acetate, formaldehyde, inorganic dust, acrolein, cement dust production. Out of 27 considered atmospheric pollutants with an increase in emissions of 13 substances (48.15%), the morbidity rate in pregnancy increases (with 8 significant correlations (the highest number) were obtained for the overall morbidity rate in pregnancy). The most high relative environmental risk for the occurrence of pathological conditions in pregnant women (six in total) in the Belgorod region in the conditions of elevated anthropogenic (pollutant) load was established to be increased by 16 (59,25%) considered air pollutants. The greatest environmental risk in high anthropogenic load of atmospheric pollutants was established for the thyroid dysfunction (OR = 1,51-2,32), circulatory diseases (RR = 1,29-1,45), edema, proteinuria and hypertensive disorders (RR = 1,17-1,44). Emissions of methane, ammonia, and sulfuric acid to the atmosphere is determined to increase the risk of five pathological conditions in pregnancy: thyroid dysfunction, diseases of the circulatory system, diseases of the urinary organs, edema, proteinuria and hypertensive disorders, anemia.
