“…1 with an enclosed scope illustrating the changes of LIRs. Although the state-owned coking plant is equipped with advanced facilities and electrostatic precipitators to control pollutants, lead in the coal that is combusted and coked in the plant could still be emitted into the atmosphere (Llorens et al, 2001). A previous study (Liang et al, 2010) estimated that lead pollution in the atmosphere is a consequence of coal combustion (50%), metallurgic dust (35%), vehicle exhaust (15%), and cement and soil (less than 2%).…”

Lead exposure in the environment is a major hazard affecting human health, particularly for children. The blood lead levels in the local children living around the largest coking area in China were measured, and the source of blood lead and the main pathways of lead exposure were investigated based on lead isotopic ratios ( 207 Pb/ 206 Pb and 208 Pb/ 206 Pb) in blood and in a variety of media, including food, airborne particulate matter, soil, dust and drinking water. The children's blood lead level was 5.25 (1.59 to 34.36 as range) μg dL −1 , lower than the threshold in the current criteria of China defined by the US Centers for Disease Control (10 μg dL −1 ). The isotopic ratios in the blood were 2.111 ± 0.018 for 208 Pb/ 206 Pb and 0.864 ± 0.005 for 207 Pb/ 206 Pb, similar to those of vegetables, wheat, drinking water, airborne particulate matter, but different from those of vehicle emission and soil/dust, suggesting that the formers were the main pathway of lead exposure among the children. The exposure pathway analysis based on the isotopic ratios and the human health risk assessment showed that dietary intake of food and drinking water contributed 93.67% of total exposed lead. The study further indicated that the coal used in the coking plant is the dominant pollution source of lead in children's blood.

“…Gaseous arsenic in coal combustion and smelting operations primarily exists as arsenic(III) oxide (As 4 O 6 ) (Cotton et al, 1999), 400; (Jadhav and Fan, 2001), 794; (Shih and Lin, 2003), although AsCl 3 may be prominent from the combustion of chlorine-rich coals at about 530-930 • C (Urban and Wilcox, 2006). As the flue gases cool after leaving the combustion zone, volatile arsenic largely condenses onto any high surface area, fine-grained fly ash particles, especially in coal combustion systems ( (Hower et al, 1999;Mukherjee and Kikuchi, 1999), 64; (Guo, Yang and Liu, 2004;Llorens, Fernández-Turiel and Querol, 2001;Galbreath and Zygarlicke, 2004); Chapters 5 and 7).…”

“…Various inorganic as well as organic contaminants are released by the coal combustion. The most important contaminants are sulphur and nitrogen oxides, carbon dioxide, fi negrained particulate matter (PM 2.5 and PM 10 ), potentially toxic heavy metals (La, Ce, Hg, Te, Th, Cr, Hf, Sc, Zn, Fe, Tl, Co, Sm, Am, As, Se, Be, Cd, Pb, and Mn), PAHs, and other combustion products (Clarke and Sloss, 1992;Querol et al, 1995;Llorens et al, 2001). In addition to endangering ecosystems at local and regional levels, coal-fi red power plants emit large amounts of carbon dioxide, which is responsible for the global problem of climate change (Duić et al, 2005).…”

Human health, the environment, and climate are being profoundly aff ected by complex pollutant interactions in the atmosphere. Almost all human activities cause the emissions of air pollutants. Their understanding and quantifi cation is the fi rst step towards the control and mitigation of air pollution. The general aim of this paper is to summarise the fi ndings of selected Croatian and Indian papers addressing air pollution, particularly those focusing on sulphur and aerosols associated with coal-fi red power plants. The two countries are essentially diff erent regarding their size, geography, history, economy, industrial potential, to name but a few. However, they both have had certain relations to the fossil fuel extraction and its usage in power stations and industry for decades. Various research approaches are presented, together with a brief outline of national air pollution policies.
