Toxic and Harmful Gases of Coking Production: Health Risks for the Population Living in the Neighborhood

Various gaseous pollutants generated in coking production have some impact on human health. Owing to BaP has carcinogenicity effect, teratogenicity effect and mutagenic effect, therefore , the assessment of human health risk duo to the coking process of project implementation released into the environment has always been a hot topic in academic research .This study, combined with a coal city in China in the use of coking coal resources and focus on the development status of the industry and planning, in full recognition coking production of waste gas sectors, according to the current conditions of coking production technology ,pollution prevention and control of possible measures, the use of atmospheric dispersion models for different weather conditions, the concentration of BaP spatial and temporal distribution were analyzed by using health risk assessment model, BaP may cause cancer risk probability is studied. The results show that :(1) In the coking furnaces exist in the sphere of influence that lead to the risk of cancer. (2) Relatively close distance of coking furnace area (1000m range), resulting in the probability of carcinogenic health risks from coking furnace than the large-scale regional. (3) In adverse weather conditions, higher than the incidence of cancer in windy weather conditions. (4) Reasonably plan the layout of coking industry to ensure a certain degree of health protection zone can significantly reduce the probability of cancer incidence.
