Industrial pollutant emission and the major smog in China

In December 2016 consecutive waves of major smog shrouded China particularly the North China Plain and Sichuan Basin resulting in suspended schools halted industrial production and heavy traffic. Atmospheric levels of fine particulate matter (PM2·5) spiked to more than 500 μg/m3 in Henan and 1000 μg/m3 in Shijiazhuang.1 Beijing even issued a red alert for pollution levels between Dec

ACTNOx Emissions from Iron Steel Mills

2.1 SOURCES OF NO X EMISSIONS Integrated iron and steel mills produce steel by reducing iron ore to iron in a blast furnace and subsequently removing excess carbon and other impurities from the iron in a basic oxygen furnace. Other processes involve beneficiating iron ore (e.g. pelletizing) recycling of iron-bearing materials (e.g.
