Determination of the air pollution index of atmospheric air in Aktobe

Abstract

Aim: The purpose of this study is to determine the air pollution index of the micro territories of Aktobe. An aerogenic ingress of the xenobiotics is the foreground among the environmental factors for urban areas. In this regard, monitoring the state of the atmosphere of cities to establish quantitative regularities of risk for the health and development of the managerial decisions on their basis should be classified as priority hygiene problems. Material and Methods: Determination of API was performed based on data obtained by three stationary atmosphere state observation points of hydrometeorological center, located on the industrial area at a distance, respectively: point 1 (VI, VII microterritories) - 18 km; Point 2 (IV, V microterritories) - 12 km; and Point 3 (I, II, III microterritories) - 3 km. Atmospheric pollution index was calculated for the five substances with the highest values. The calculation was based on the content of following elements in the urban-industrial environment: iron, manganese, hexavalent chromium, magnesium, and vanadium which possess the immunotropic action. Results and Discussion: The results obtained by calculation of API show that the highest pollution index is observed at point that is 1.6 times greater than in the first observation point and 1.8 times in the second observation point. This is explained by the fact that the inhabitants of I, II, and III microterritories are the closest to the industrial zone and the most exposed to harmful air substances. Conclusion: This is explained by the fact that the inhabitants of I, II, and III microterritories are the closest to the industrial zone and the most exposed to harmful air substances.
