Air quality worsening in China’s Yangtze River Delta in 2018, figures show
Region around Shanghai experiences rise in lung-damaging particles PM2.5 in the period from January to April
Air quality in the major Chinese manufacturing hub around the Yangtze River Delta worsened in the first four months of the year, largely because of a 20 per cent surge in emissions in January, environment ministry data showed on Wednesday.
In the region, which includes Shanghai, concentrations of the lung-damaging particles PM2.5 (particulate matter) rose 1.9 per cent from a year earlier to hit an average of 55 micrograms per cubic metre over the period, the Ministry of Ecology and Environment said in a statement.
The particles have a diameter of less than 2.5 micrometers, so small that they can be detected only with an electron microscope.
Environmental groups have said they are worried that the government’s focus on smog in northern China has driven industrial production and pollution further south.
China is currently drawing up a new 2018-2020 action plan to further improve air quality after meeting its 2013-2017 targets.
