READINGS of airborne particles smaller than 2.5 micrometers - known as PM2.5 -in the city of Lanzhou, one of China's most polluted, will be available for public scrutiny next month, according to officials. The capital city of Gansu Province will start PM2.5 monitoring according to new environmental air quality standards on Saturday.
Lanzhou is among the first of 74 Chinese cities required by the Ministry of Environmental Protection to publish daily reports on PM2.5 by the end of the year.
The PM2.5 index is considered stricter than the PM10 standard previously adopted in China. The tiny particles are more hazardous to people's health.
The data will be updated on government websites and via television and radio before the end of the year, the head of Lanzhou Environmental Protection Bureau, Pan En, said.
The move was hailed by local residents who have complained of air pollution in the northwestern city.
"What matters is not the reading itself, but that its publication can at least put pressure on officials to do something to alleviate the pollution," said Pan Jiang, a local citizen.
Shanghai began using the new standard this month.
Experts said terrain and climate factors, and Lanzhou's reliance on petrochemical industries and its winter heating, have worsened pollution. A World Health Organization survey in 2011 named it China's worst for air pollution.
