It's alarming when people can't see the smog for the pollution

Website aims for less hazy presentation of smog data

Confusion over the government's online pollution statistics and news that roadside pollution hit its worst-ever level last year have inspired a rival website delivering the city's latest air-quality figures.

The site by web developer Steve Holmes lets users generate custom air-pollution graphs by time interval, pollutant and monitoring station.

App shows you how bad the air really is

A father who feared pollution was damaging the health of his two young children and mistrusted the official statistics has built a free iPhone application to monitor air quality.

Tech-savvy entrepreneur Andrew Leyden arrived in Hong Kong two years ago and like many, wondered how bad the pollution actually was.

Delta leads nation on dirty-air data

The Pearl River Delta is a step ahead in releasing up-to-the-hour information on microscopic pollutants across the region, including Hong Kong, as it seeks to clear the air on a pressing environmental threat.

Truth about pollution still shrouded by secrecy

The Year of the Dragon has been greeted with a stubborn shroud of white haze that refuses to lift from the capital.

It resembles the haze of secrecy still blocking access to key environmental information, from the government's clean-up spending to pollution data to related diseases and protests.

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.

Clean-air targets don't measure up, critics say

Hong Kong's clean-air targets will be toughened for the first time in a quarter of a century from 2014, but they will still fall short of World Health Organisation standards.

Roadside pollution is worse than ever

Hong Kong's roadside pollution levels were the worst ever last year, according to the Environmental Protection Department.

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.

Defending cleaner air measures

Lai See has taken the government to task over air quality, most recently in the piece ('Light to be shed on air quality', November 3). These comments require clarification.
