“…Emission factors for CO, NO x , NMVOCs, BC, and OC, tend to be dependent on details of the emitting process and therefore have higher uncertainties (Blanco et al, 2014). This is particularly true for carbonaceous aerosol emissions, where emission factors can range over several orders of magnitude depending on the conditions under which combustion occurs.…”

Abstract. We present a new data set of annual historical anthropogenic chemically reactive gases (CO, CH 4 , NH 3 , NO x , SO 2 , NMVOCs), carbonaceous aerosols (black carbon -BC, and organic carbon -OC), and CO 2 developed with the Community Emissions Data System (CEDS). We improve upon existing inventories with a more consistent and reproducible methodology applied to all emission species, updated emission factors, and recent estimates through 2014. The data system relies on existing energy consumption data sets and regional and country-specific inventories to produce trends over recent decades. All emission species are consistently estimated using the same activity data over all time periods. Emissions are provided on an annual basis at the level of country and sector and gridded with monthly seasonality. These estimates are comparable to, but generally slightly higher than, existing global inventories. Emissions over the most recent years are more uncertain, particularly in low-and middle-income regions where country-specific emission inventories are less available. Future work will involve refining and updating these emission estimates, estimating emissions' uncertainty, and publication of the system as open-source software.

“…Power generation using coal provides energy for daily life and industry, but it also produces atmospheric pollution, water pollution, all of which disrupt ecological cycles. FA pollutes the atmosphere and threatens human health if it is discharged directly from power plant chimneys into the atmosphere without treatment [7,8]. This is a significant contributor to China's recent air quality and haze problems [9,10].…”

“…FA particle sizes range from 0.5 µm to 300 µm, and their bead walls have porosities of 50%-80% with high water absorption [14]. In addition, FA contains valuable oxide components, such as SiO2, Al2O3, CaO, MgO, Na2O, TiO2, and essential elements, including P, K, Mg, Zn, Fe, Mn, and others [5,7]. Therefore, FA has attracted the attention of many researchers.…”

Air pollutants such as volatile organic compounds (VOCs), nitrogen oxides (NOx), sulfur dioxide (SO2), as well as water pollutants including heavy metal, are harmful to human and 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, the FA can also be used as a low-cost and high efficient adsorbent with some simple modifications. This paper reviews the effects of FA on treatment of the above air and water pollution based on our research experience over many years, including to the current status of global FA utilization, physicochemical properties, principle of adsorption, and the application direction of FA in the future. It focuses on the use of nanocomposite technology to fabricate functional FA fibrous membranes to adsorb VOCs from air, and treat heavy metal wastewater. This present review first describes the fabrication technology of FA nanocomposites and their mechanism of adsorption VOCs from air. 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 use of pollutant material to control other pollutants.

“…Therefore the high level of independence of the electrical generating companies from fuel providers could be realized. Besides, the CWSP and CWS are more fire safe [6][7][8][9] and more ecological (the air pollution by sulfur and nitrogen oxides at the CWS usage is quite low [10][11][12][13]) relative to traditional coal dust fuels. Taking into account, that list of the possible fuel components is very reachable, the properties of different types of coal wastes could be very different.…”
