Air quality improves
April 28, 2011
Overall regional air quality further improved last year.

The Environmental Protection Department and the Guangdong Department of Environmental Protection reported today 77% of the Regional Air Quality Index was within Grade II, as recorded by the Pearl River Delta Regional Air Quality Monitoring Network in 2010. This means pollutant concentrations were within Class 2 National Ambient Air Quality Standards.

The four major air pollutants were sulphur dioxide, nitrogen dioxide, ozone and respirable suspended particulates. The overall concentrations of most pollutants were generally higher in winter while lower concentrations were recorded in summer. A similar pattern was recorded last year.

Air quality was better in the coastal areas, which have better conditions for the dispersion of pollutants. This situation is in line with observations from previous years.

Well that's what the Government thinks.
