    Air quality a serious problem

    Comment on "Guangdong adds more PM2.5 monitoring sites" (China Daily, June 3)

    The news that Guangdong province will set up more than 100 sites in 21 cities to monitor PM2.5 (particulate matter or droplets in the atmosphere that are 2.5 microns or less in width and harmful to human health) by the end of this year is good news. It shows that Guangdong environmental authorities are determined to fight air pollution and protect people's health.
