“…These studies showed that railways have significant influence on heavy-metal concentrations in surrounding areas [73,74], and the concentrations of several heavy metals decreased with increasing distance from the railroad [75,76]. In coal transportation hubs, the flow of trains through the hubs is resulting in inestimable pollution [77,78]. Because trace Cr and Pb affect human metabolism and may lead to cancer [19,79,80], the government should monitor railway lines [77] for these three heavy metals.…”

“…Except for the amount of transported coal cannot be reduced, many technologies are also lacking to effectively control pollution resulting from coal transportation [77,83] and mining [84], so heavy-metal pollution is inevitable where these activities take place [21,28,85]. In addition, the concentration of heavy metals in coal varies by location due to differences in the geological environment [86].…”

“…The impact of coal transportation hubs on the environment cannot be ignored. The methods that were used in this study are generally applicable to assess any railway’s scope of influence [77,83,93] on heavy metals in street dust at any coal transportation hub. It should be noted, however, that restricting such analyses to the areas immediately around railway lines is insufficient to address the problem of heavy-metal contamination, because contamination is also attributable to other industries and to the population living near the hub [55,56].…”

Coal is a vital basic energy source in China, and rail serving is its major mode of transportation. Heavy metals in street dust surrounding the coal railway do harm to the environment and pose a potential risk to human health. This paper aims to identify the effects of coal transportation hubs on heavy metals in street dust. The geoaccumulation index and ecological risk index were used to assess the contamination levels of the following elements in Yuanping, Shanxi: arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), mercury (Hg), nickel (Ni), lead (Pb), and zinc (Zn). The levels of contamination of these heavy metals in soils were compared to those in street dust, and the difference between the railway’s and mining’s impacts on dust’s heavy-metal concentrations was explored. The results indicated that Cr and Pb in street dust were mainly affected by coal railway transportation, and the interaction effect of coal railway transportation and mining was greater than either of them alone. A potential control and prevention zone for Cr and Pb extending 1 km to both sides of the railway was identified. This work proves that coal railway transportation has certain effect on heavy metals in street dust and provides a scientific approach for future environmental impact assessments of coal transportation via railway.

Identifying Key Sources of City Air Quality: A Hybrid MCDM Model and Improvement Strategies

Improvements for air quality were prioritized according to gaps between criteria. Existing improvement strategies for air quality often focus on a single criterion, without considering associations among criteria. Moreover, solutions are often temporary, failing to provide long-term improvement. Therefore, this study employed a multiple-criteria decision-making model and a substitution method based on causal relationships to analyze potential improvement strategies for air quality in Kaohsiung, Taiwan. Results revealed that coal-fired power plants and factory emissions are the major sources of pollution in Kaohsiung. This study suggests that environmental authorities in Kaohsiung should facilitate plants to improve energy efficiency with anti-pollution facilities.
