“…SO 2 and CO pollution in heavy industrial cities, such as iron and steel industrial cities (Anyang, Handan, and Xingtai) and coal industrial and chemical industrial cities (Hebi and Shijiazhuang), is far worse than that in Hangzhou and Beijing ( p < 0.05). In Beijing, SO 2 and CO concentrations rise significantly from summer to winter in 2016, but the average value of 2018 is lower than the other cities ( p < 0.05), which should be linked to the prohibition of coal burning except power plants (Finkelman & Tian, 2018; Y. Zhang, Liu, et al, 2018; Y. Zhang,Ye, et al, 2018; Zhao & Luo, 2018). This suggests that SO 2 and CO pollution in Beijing was mainly caused by urban biomass burning or coal burning.…”

“…Actually, the above four industrial cities implement the critical ultralow emission standards since 2017 in coal fire power plants, steel, and coking factories (Wu et al, 2019), which led to significant decline of the concentrations of SO 2 . However, the SO 2 emission is inevitable and the ratio of the highest to the lowest monthly concentration are still higher than Beijing, indicating the implementation of policies among different cities, as well as industrial conformation, energy structure and meteorological conditions, affect the concentrations of pollutants (Ma et al, 2015; Zhao & Luo, 2018).…”

Air quality in Northern China has become a global hot spot issue due to a series of air pollution events in the recent years. In this study, five representative air pollutants (PM 2.5 , SO 2 , NO 2 , CO, and O 3 ) were employed to reveal the spatial and temporal distribution of air pollution in Northern China. Periodic decline in PM 2.5 , SO 2 , CO, and NO 2 from 2016 to 2018 indicated that air pollution control measures have achieved desired results. In addition, PM2.5 was significantly positively correlated with SO 2 , CO, and NO 2 (p < 0.001), and O 3 had negative correlations with the other four pollutants. Furthermore, the heavy pollution phenomenon in Shijiazhuang, Anyang, Xingtai, and Handan was attributed to their industrial structures (e.g., steel industry) and geographical location based on clustering analysis. Contrary to above four pollutants, the annual average concentrations of O 3 increased in all the nine cities (1.4-35.9%) from 2016 to 2018. It is necessary to plan mitigation strategy for O 3 based on further investigation of source and formation mechanism of O 3 .Plain Language Summary Air pollution in Northern China has attracted many attentions due to continuous air pollution issues in the recent years. However, few studies focused on air pollution in the Beijing-Tianjin-Hebei transmission corridor. In this study, the spatiotemporal variation of air pollutants in nine typical cities was investigated. Pearson correlation analysis and clustering analysis were employed to analyze their relationship and reveal the pollution characteristic and the factors affecting the air pollution. This study provided an insight for the prevention and control of air pollution in Northern China.

“…The optimal rate of thermal transfer k * and the optimal quantity of carbon emission e s * exist. Supposing that dπ s dk = 0 and dπ s de s = 0, from the above, the optimal k * and e s * can be obtained in Equation (2). The above Hessian matrix is negative, and the optimal quantity of thermal power ordered Q m * and the optimal quantity of carbon emission e m * in the electric enterprise exist.…”

For reliving the pressure of air pollution and corresponding the sustainability development policy in China, the companies are urging the creation of a highly productive low-carbon supply chain. This work uses price regulation, the cap-and-trade model, and a green financial policy background to establish a strategy for the coal-electric power supply chain with two-level carbon reduction and operation with financial constraints. A Stackelberg model was built to help investigate the rate of thermal order realization, the carbon reduction strategy in the coal enterprise, and the amount of thermal energy ordered in the electric enterprise. Results show that under a green financial background, a high bank loan discount rate for investing in carbon reduction technology equates to large carbon reduction in coal enterprises, large quantities of thermal energy ordered in electric enterprises, and high profit for coal and electric enterprises. However, the realization rate of thermal power ordered decreased when the price regulation become strict, thereby reducing the profit and carbon emission in electric enterprise. Therefore, the thermal price regulation level increased, the profit on both company and the production did not respond with sensitivity, and the government could encourage a low carbon model by controlling the bank loan rate.Sustainability 2019, 11, 3021 2 of 17 2008, different kinds of toxic gas such as sulfur, arsenic, fluorine, and mercury emissions rose sharply, caused by domestic coal burning. However, oppositely, the quantity of emissions from coal-fired power plants decreased [2]. From the above data, the environment problems due to the domestic coal burning in rural communities have been paid attention to, and the control on air pollution should have been put forward. Due to the harsh environment situation, the scholars attempted to solve environmental pollution, and the future research fields should focus on how to improve the technology of reducing carbon emission while preventing costs from increasing, in practice, environment-friendly ideas that are widely spread and accepted [3].The amount of thermal power was kept at a high level and was enough, and the need for coal products decreased remarkably in the coal trade market. Consequently, the country also introduced clean energy, the resource of electric power mostly originated from "green" or "clean" energy, for example, wind power, nuclear power, and water power. The amount of carbon emission reduction from global electric power, including heat power, accounted for 40% of the total global percentage [4]. In our country, the electric power resource is restrained by the limitations of the Earth's power resource. Most of the electric power is transferred from coal products, the coal-electric power channel being one of the important supply chains in the electric power market, and thermal being the main electric power supplier. The portion accounts for more than 70%, and the consumption of the coal products accounts for half of the total of the entire...

“…With rapid industrial development, large demand for electricity has led to hundreds of millions of tons of FA (around 80% of which is fly ash) being discharged every year worldwide. The annual coal consumption of China in 2015 was about 50% of the global coal consumption [6]. Power generation using coal provides energy for daily life and industry, but it also produces atmospheric and water pollution, which disrupts ecological cycles.…”

Air pollutants such as volatile organic compounds (VOCs), nitrogen oxides (NOx), and sulfur dioxide (SO 2 ), as well as water pollutants (e.g., heavy metals phosphorous, fluoride, boron, phenolic compounds, and dyes), are harmful to humans and the environment. Effective control and reduction of their pollution is therefore an important topic for today's scientists. Fly ash (FA) is a type of industrial waste that can cause multiple environmental problems if discharged into the air. On the other hand, because of its high porosity, large specific surface area, and other unique characteristics, FA can also be used as a low-cost and high efficient adsorbent for treatment of environment pollutants. This paper reviews the effects of FA on treatment of the air and water pollution, including to the current status of global FA utilization, physicochemical properties, principle of adsorption, and the application direction of FA in the future. Since most researchers only studied the adsorption capacity of pure FA or zeolite (synthesized from FA), the research on the fabrication of nanofiber membranes using FA is still lacking, especially the adsorption of VOCs from air and heavy metals from wastewater using FA nanofiber membranes. Therefore, in this paper, we focus on reviewing and summarizing that FA can be spun into a fiber membrane via electrospinning with the ability to adsorb VOCs and heavy metals from air and wastewater. Moreover, we also evaluate the future application value of FA nanofiber membranes in the field of environmental pollution control. Utilization of nanofiber technology to fabricate multi-functional FA emerging composite materials to mitigate air and water pollution has great potential in the future, especially the use of pollutant materials to control other pollutants.
