Nanjing steel mills face output cuts to reduce ozone pollution

SHANGHAI, Jun 5 (SMM) – Steel and petrochemical companies in Nanjing, Jiangsu province will be required to cut at least 50% of production from June to September, as part of the city's efforts to reduce the number of high ozone-pollutant days in the summer. 

The city's cement and foundry industries will take it in turns to be suspended for a certain period of time, SMM learned. 

These measures were part of an action plan to clamp down on the emission of ozone-damaging substances. The period of control is from June 1 to September 30.

Smog in the summer pollutes the air and damages the earth's protective ozone layer. Ozone depletion will damage ecosystems, crops and cause long-lasting health issues.

Chemical reactions between nitrogen oxides and volatile organic compounds (VOCs) in the presence of sunlight producer emissions that damage the ozone layer. Emissions from industrial facilities, motor vehicle exhaust, and gasoline vapours are some of the major sources of nitrogen oxides and VOCs.
