Daily ozone and carbon monoxide measurements may be included in Shanghai air quality reports to meet new standards proposed by the Chinese Ministry of Environmental Protection. The ministry wants to bring China’s air quality reports into line with international standards.
Local environment authorities will be required to publish air quality daily reports based on these standards and make forecasts for up to 48 hours.
The reports grade air quality as excellent, good, lightly polluted, moderately polluted and heavily polluted.
Ozone is a key indicator of air pollution, according to professor Le Qun of East China Normal University‘s Resources and Environment School. Urban areas with heavy traffic and large industrialized communities are the main areas with ozone problems, he said.
In cities, most carbon monoxide emissions come from motor vehicle exhaust, posing a health risk for those who suffer from cardiovascular disease.
Shanghai’s current air quality daily reports and 24-hour forecasts are available at the Websites of the Shanghai Environmental Protection Bureau, the Shanghai Environmental Monitoring Center and the Shanghai Environment Hotline.
