Assessment of influence of air pollution produced by engineering enterprises on human health

Production, operation and service of mechanical and aerospace engineering systems can be the source of dangerous pollutants. This work investigates the improvement of scientific and methodical bases to manage the cancerigenic danger to population health from air pollution caused by stationary and non-stationary emission sources. The analyses of epidemiological data showed that cancer mortality has grown by 30 % concerning total mortality in Krasnoyarsk from 2000 to 2012. The analysis of air pollution showed that concentrations of some cancerigenic substances increased significantly during 12 years according to the data of state network of monitoring posts. The pollutants that give the greatest contribution to mortality of various cancers were revealed. This pollutant emission sources are analysed. It is difficult to blame a single source as being responsible for the high levels of air pollution with cancerigenic effect on human health in Krasnoyarsk city. The cancer latency period has been estimated by statistical methods. The correlation analysis applied to determine the most sensitive organs and systems of the person influenced by cancerigenic pollutants. Benzopyrene has influence on the greatest number of target organs and systems: digestive system (stomach, liver, pharynx), immune system (limphoma), brain and nervous system. The assessment of a time lag for cancer of various organs and systems is executed with using the cross correlation functions. The longest effect with time lag 12 years is observed for digestive and respiratory cancer. The offered approach allows us to carry out an operative assessment of impact of carcinogenic effect on health of the plant's staff and inhabitants of the surrounding.
