“…As a coke and ironesteel industrial center, Taiyuan is one of the most polluted cities in China (Yang et al, 2011). Moreover, coal and coal products dominate the fuels in commercial and residential sectors in Taiyuan and the surrounding area (Meng et al, 2007). Very high concentrations of atmospheric PAHs in Taiyuan have also been reported recently (Xia et al, 2013).…”

“…The air pollution is strongly affected by emissions from power generation, industry, transportation, commerce, and residences. For example, Taiyuan is a heavily industrialized city with a large number of coal-fired power generators, coke ovens, and steel furnaces (Meng et al, 2007). On the other hand, emissions from transportation and commercial activities contribute a substantial share of air pollution in Beijing (Sun et al, 2004).…”

a b s t r a c tAtmospheric PM 10 were measured for 12 months at 18 sites along a 2500 km profile across northern China. Annual mean PM 10 concentrations in urban, rural village, and rural field sites were 180 AE 171, 182 AE 154, and 128 AE 89 mg/m 3 , respectively. The similarities in PM 10 concentrations between urban and rural village sites suggest that strong localized emissions and severe contamination in rural residential areas are derived from solid fuels combustion in households. High PM 10 concentrations in Wuwei and Taiyuan were caused by either sandstorms or industrial activities. Relatively low PM 10 concentrations were observed in coastal areas of Dalian and Yantai. Particulate air pollution was much higher in winter and spring than in summer and fall. Multiple regression analysis indicates that 35% of the total variance can be attributed to sandstorms, precipitation and residential energy consumption. Over 40% of the measurements in both urban and rural village areas exceeded the national ambient air quality standard.

“…The OC/TSP and EC/TSP ratios in the ambient air of the coking plant were similar to the ratios at the coke-oven top, indicating that the OC and EC in the plant area arose mainly during coking. OC and EC contributions to PM 10 in four cities in Shanxi were in the range of 10.5%-16.9% and 11.7%-21.5%, respectively (Peng et al, 2011). Meng et al (2007 reported that OC and EC accounted for 18.6% and 2.9% of PM 2.5 in winter in Taiyuan, Shanxi.…”

To investigate the characteristics of organic carbon (OC) and elemental carbon (EC) in the ambient air of coking plant, particulate matter samples were collected and analyzed. The OC and EC mass concentrations were in the range of 104.2-223.2 µg/m 3 and 93.7-237.8 µg/m 3 , respectively, which were much higher than those in the ambient air of industry, highway, and urban roadway tunnel. The OC concentrations did not significantly differ at the coke side and the machine side, whereas the EC concentration was significantly higher at the coke side. The OC/EC ratios ranged from 0.74 to 2.35, and coking was the primary source of OC and EC. Carbonaceous aerosol was a large component in the ambient air, and the total carbonaceous aerosol (TCA) accounted for 39.1%-73.0% of the total suspended particulates (TSP). TCA contributions to TSP were consistent at the coke side and the machine side, and both contributions were lower than those at other sampling sites. OC and EC emission control must be strengthened for improving coking plant air quality and reducing health hazards to coke-plant workers. OC-EC correlation was evident, with a correlation coefficient of 0.976 (p < 0.05) at the coke-oven top, coke side, and machine side, whereas no significant correlations were observed at sites downwind of the coke oven (p > 0.05).

“…were mainly produced from heavy polluting industries (Wu et al, 1997). Taiyuan city is not only a cultural center of Shanxi province, but also one of the key industrial bases in China, with a population of approximately 3.6 million (Meng et al, 2007). The polluting heavy industries are mostly situated in the southern, urban area of Taiyuan, which means that there is the potential for residents to be exposed to OCPs.…”

a b s t r a c tAs one of China's great metropolises, Taiyuan is generally recognized to be one of the most polluted cities in the world. It is affected by pollution from heavy industries, and from organochlorine pesticides (OCPs). In this study, we measured the concentrations of OCPs in various environmental media in Taiyuan. We measured the levels of OCPs in 15 soil samples and 34 samples of respirable particulate matter (PM) (17 of PM 2.5 and 17 of PM 10 ) from urban areas of Taiyuan. Analysis of the composition ratios of OCP residues revealed that dichlorodiphenyltrichloroethane (DDT) and hexachlorocyclohexane (HCH) were the predominant compounds in soil, PM 2.5 and PM 10 . The total DDT concentrations were 1.8-1.0 Â 10 2 ng g À1 in soil, 6.5-1.0 Â 10 3 pg m À3 in PM 2.5 , and 8.5-1.5 Â 10 3 pg m À3 in PM 10 . The total HCH concentrations were 1.4-45 ng g À1 in soil, 5.2-8.0 Â 10 2 pg m À3 in PM 2.5 , and 9.6-8.7 Â 10 2 pg m À3 in PM 10 . Furthermore, source analysis indicated that there was new input of OCPs at some sites. Finally, analysis of the individual OCPs revealed that new OCP contamination was the major problem in Taiyuan. This study suggests that measures should be taken to reduce the levels of OCP residues in order to improve the environmental quality in Taiyuan.
