“…It has been confirmed that CFA conducts as a carrier of hazardous trace elements (HTEs) [133,134]. Although fabric filter or electrostatic precipitator had been widely equipped in smokestacks of power plants, PM with various assemblies of HTEs caused by CFA releasing still resulted in high risk on atmospheric environment and human health [135][136][137][138][139]. Dwivedi et al [140] found that oxidative DNA damage in human cells was attributed to nanoscale CFA.…”

To provide a comprehensive insight into the enrichment mechanism of gallium and indium in No. 9 coals, eighteen samples were collected from Anjialing mine, Ningwu Coalfield, Shanxi Province for coal petrological, mineralogical and geochemical analyses. The results suggested that Ga and In enrichment mainly hosted in the top horizons, with average concentration coefficients of 8.99 and 2.73 respectively, compared with the rest of horizons (2.46 for Ga and 1.69 for In). Source apportionment indicated that Ga and In were mainly derived from bauxite of Benxi Formation in Yinshan Oldland, while In could originate from felsic magmatic rocks in Yinshan Oldland as well. In addition, weak oxidation condition, medium to intensive weathering, transgression and input of terrestrial higher plants had positive effects on Ga and In enrichment. With the rapid expansion of emerging electronics manufacturing, Ga and In, of which potential risks on human health were neglected previously, were recently considered as hazardous elements. Therefore, this paper also discussed the potential pathways that these elements threatened human health. We suggested that potential risks on environment and human health caused by Ga and In enrichment in coals and coal-related products should be taken into account besides their economic value.

“…In a desulfurization system, particles >1 μm can be further removed, and the removal rate of Fe is up to one third. 72 The dissolution of soluble Fe and redox processes involving Fe 2+ /Fe 3+ would contribute to the redistribution of Fe-bearing chemical species. 73 In addition, magnetite has been proved to be a strong adsorbent and oxidative catalyst for heavy metals like Hg 0 , and the adsorption or oxidation process in the desulfurization system may also alter the surface properties and associated elements of MPs.…”

The intensified contradiction of economic growth and environmental protection has gained a lot of attention from multidisciplinary scholars. The relationship between socio-economic factors and deadly concentration of PM2.5 remained poorly understood specifically for the developing countries. The study has selected Next-11 countries for the analysis to gauge the influencing factors of PM2.5 concentrations by collecting data from 1995-2017. The cross-sectional dependence test shows mixed results therefore, the study has employed both the first generation and second generation econometric techniques. The results of the panel unit root test indicate that all the variables are stationary at first difference. In Auto-Regressive Distributive Lag (ARDL) estimation, the longrun co-integration vectors show that renewable as well as non-renewable energy have significant long-run co-integration. Gross domestic product is the main influencing factor of PM2.5 concentrations while its quadratic form has a negative association that verifies the existence of the Environmental Kuznets Curve (EKC) in sampled countries. The Westerlund co-integration test also verifies the long-run integration among variables. The results of Fully Modified Least Square (FMOLS) and Dynamic Least Square (DOLS) indicate significant negative relation of industry value-added, trade openness and urbanization. On the other hand, the results of the Dynamic Common Correlated Effect (DCCE) indicate the positive impact of urbanization on PM2.5 concentration. This is the first study that is showing the key contributing factors of PM2.5 concentrations for N-11 countries. Authors have suggested the rational formulation and careful implementation of policies.
