Air quality improved nationwide in April
June 12, 2014 Category Environment, Pollution
Air quality in major parts of China was better in April than in March, with dust and ozone accounting for a larger proportion among the key pollutants, according to statistics released by the Ministry of Environmental Protection (MEP). The statistics show that air quality in 74 Chinese cities met national standards 70.6% of the time in April, an improvement over March’s 62.3%. The number of cities scoring above 80% also rose, from 22 in March to 29 in April. In contrast with the progress made by the 74 major cities as a whole, air quality in the most-polluted area-the Beijing, Tianjin and Hebei province cluster-got slightly worse in April. Nine cities out of the 13 in this region appeared on the list of the top 10 cities with the worst air quality. The number in March was seven. As the seasons changed, PM2.5 was not as dominant among pollutants in April as in March. For the Beijing, Tianjin and Hebei province cluster, PM2.5 was still responsible for most of the days with bad air quality. But the proportion of polluting days caused mainly by PM10, which are larger particles, rose by 10 percentage points in this region from March to April. The region has entered the season when sand dust becomes common, Zhang Mingying, Senior Engineer from the Beijing Meteorological Bureau, said. In the hotter and more humid cities in the Pearl River Delta, ozone became the top pollutant in April, accounting for 73.7% of the bad-air days. In March, more than 85% of high-pollution days were caused by PM2.5. The 10 cities with the worst air quality in April were Xingtai, Tangshan, Shijiazhuang, Handan, Baoding, Qinhuangdao and Langfang, all in Hebei province; Jinan in Shandong province; and Tianjin and Beijing, the China Daily reports.
