Beijing releases data on fine particles

Beijing environmental authorities yesterday began releasing hourly air pollution readings for PM2.5 - health-threatening fine particles with a diameter less than 2.5 microns - fulfilling a promise of publicising them before the Lunar New Year, under intense public pressure.

Challenge leaves us all out of breath

The immensity of the challenge facing environmental officials responsible for cleaning the city's air has been exposed by a study which has matched their latest targets with last year's air quality figures.

The worst discrepancy is for nitrogen dioxide, a pollutant generated mainly by vehicles.

Fine particles nearly 10 times WHO ceiling

Yang Changjiang did not realise how much Beijing's air quality had deteriorated until he tested it himself. Using a hand-held detector, the veteran environmental reporter and his family began a 10-day experiment early last month. They stood at the side of the road in the capital's Zhongguancun district, testing for fine airborne particles up to 2.5 microns in diameter called PM2.5.

Greens put HK air 'shame' on the map

The level of fine particles - specks of pollutants that can penetrate the lungs - in Hong Kong's air is among the worst in more than 500 cities and at least 20 times that of the cleanest metropolis.

New pollution figures on way ... in five years

The mainland's top environmental watchdog has finally unveiled a timetable for long-awaited reform of outdated air pollution standards amid mounting public pressure.

But instead of directly answering calls for immediate public access to official data on smog-related fine particles, the environmental ministry set a distant deadline of 2016 for its mandatory release.

Access to full smog data still out of sight

The heated debate over public access to key smog-monitoring data has taken another turn, with the mainland's top environment official putting a damper on hopes that more complete standards are imminent.
