Shanghai started releasing hourly readings of PM2.5 from 10 new monitoring spots on June 27, and will conduct stricter environmental-protection measures in six areas: water, air, solid waste, industry, agriculture and ecology. Shanghai has been releasing 24-hour PM2.5 combined measurements from just two spots — one in Putuo District and one in Zhangjiang in the Pudong New Area since March as a trial. The Shanghai Environmental Protection Bureau has installed 24 local spots and 10 new national spots to monitor PM2.5. The PM2.5 information is available in Chinese on www.semc.gov.cn. By the end of this year, Shanghai will officially announce the hourly and daily readings of all six types of pollution — PM10, sulfur dioxide, carbon dioxide, PM2.5, ozone and carbon monoxide — under a national new air quality monitoring standard. More than 20 cities, including Guangzhou, Xiamen and Nanjing, publish daily PM2.5 data. To deal with noise pollution, the Shanghai government has kicked off tighter measures and installed more barriers along the elevated highways, and stepped up management of construction sites.
