Ecologoepidemiological Connection of Lung Cancer Morbidity With Atmospheric Air Pollution by Carcinogens in Petrochemical Profile Regions

Abstract

Aim. To study the dynamics of lung cancer (LC) morbidity among the population of five cities of the Republic of Bashkortostan over the period from 2010 to 2016 and the structure of industrial emissions for grounding of adequate integral index, connected with LC morbidity and development of preventive measures to decrease malignant neoplasms. Materials and methods. The structure of gross emissions of industrial enterprises and ecologohygienic assessment of atmospheric air was conducted according to the materials of the Department of Rospotrebnadzor in Bashkortostan for 2010-2016. Lung cancer morbidity in the above mentioned territories was studied by the materials of Republican Clinical Oncological Dispensary. To estimate the influence of gross emissions on LC morbidity, modeling technique, adequate to panel analysis of spatially dynamic structural data, was applied. Results. The assessment of carcinogenic risk of atmospheric air emissions, taking into account not separate carcinogens, but their combined effect as substances with similarly directed impact, detected accurate correlation of dependence of high LC morbidity on the resultant carcinogens action. Conclusions. High LC morbidity in the cities of Bashkortostan is connected with high gross emission of carcinogens into the atmospheric air. Information on gross emissions of carcinogens and their structure can serve as an integral criterion of atmospheric pollution impact on lung cancer morbidity.
