年底實施的空氣質素健康指數（AQHI）就粒子濃度，細分成可吸入懸浮粒子（PM10）及微細懸浮粒子（PM2.5），後者為新納入計算的污染物，有醫生指其對身體損害更嚴重，早應納入計算範圍。

微細懸浮粒子終納入計算（2013年2月7日）。蘋果日報，取自 http://hk.apple.nextmedia.com/news/art/20131207/18540575

At roadsides, concentrations of respirable suspended particulates (PM10) dropped by 15 per cent, fine suspended particulates (PM2.5) by 12 per cent, and ¬sulphur dioxide (SO2) by 10 per cent.
