The calculation methods for the emissions of air pollutants and CO2 (HC, NOx, CO, PM, SO2, and CO2) have been extensively outlined in prior studies (You et al., 2022). 2.2. ChinaHighAirPollutants (CHAP) dataset and processing The ChinaHighAirPollutants (CHAP) dataset was used to ...
At the start of the second quarter of 2021, the quality of the air in Jiaozuo was classed as being “Moderate” with a US AQI number of 57. This is in line with the recommendations from the World Health Organisation (WHO). The recorded levels of the 6 main pollutants were as follows:...
The first aerial observations of atmospheric pollutants over mainland China were performed as an international collaborative research effort in March, 2002. Observation flights over Bo Hai were made from Dalian to Dandong, Jinzhou, and Qingdao. High concentrations of gaseous pollutants (O 3, SO 2, ...
the smog in the northern region is still very serious. The analysis of experts from the National Centre for Air Pollution Prevention and Control is that “ fireworks and firecrackers have caused a large increase in pollutants ” and that “ highly polluting steel, coking, glass, refractory materi...
Between 2002 and 2017, China’s gross domestic product grew by 284%, but this surge was accompanied by a similarly prodigious growth in energy consumption, air pollution and air pollution-related deaths. Here we use a combination of index decomposition analysis and chemical transport modelling to ...
PM2.5 is one of the major pollutants of the air pollution in Beijing and it poses the greatest risk to human health. Its concentration reached a record high of 993 on January 12, almost 50 times the World Health Organization'sremended level. PM2.5 levels across most of Beijing have been ...
