Daily report on PM 2.5 density soon

SHANGHAI - Pilot monitoring showed the density of PM 2.5 in Shanghai exceeded the national standards of grade II air quality from 2006 to 2010. A daily report on PM 2.5 level in Shanghai will likely be published from next year.

PM 2.5, known as the smallest and most hazardous airborne pollutant, is smaller than 2.5 microns in diameter. Getting these inside one's lungs is harmful. Since autumn, when consecutive smoggy days severely disturbed people's lives in Beijing and other big cities in China, it has become something of a household word associated with health concerns.

Shanghai Environmental Monitoring Center (SEMC) said on Friday that they have been carrying out pilot monitoring of PM 2.5 since 2005, and now had 24 monitoring spots in Shanghai. Monitoring results showed that the level of PM 2.5 failed to reach the national standards for grade II air quality.
