Air Quality Health Index

空氣質素健康指數

為向市民提供更適時及有用的空氣污染資料，環境保護署(環保署)於2013年12月30日推出空氣質素健康指數，以取代空氣污染指數。
To provide more timely and useful air pollution information to the public, the Environmental Protection Department (EPD) launches the Air Quality Health Index (AQHI) to replace the Air Pollution Index (API) from 30 December 2013.

空氣質素健康指數告知你由空氣污染引發的短期健康風險，以便你能採取預防措施，保障健康。
The AQHI informs you of the short-term health risk of air pollution and helps you take precautionary measures to protect your health.

空氣質素健康指數以1至10級及10+級通報，並分為以下五個健康風險級別。
The AQHIs are reported on a scale of 1 to 10 and 10+ and are grouped into five health risk categories as shown below.


健康風險級別 Health Risk

低
Low

中
Moderate

High

甚高

EPD - 空氣質素健康指數 Air Quality Health Index (AQHI)
將在2013年12月30日啟用
Coming soon, launching day on 30 December 2013

 

環保署將於十二月三十日推出「空氣質素健康指數」
指數是以四種空氣污染物，包括臭氧、二氧化氮、二氧化硫和粒子（可吸入懸浮粒子及微細懸浮粒子）的三小時移動平均濃度所引起的累積健康風險作為計算基礎。

Air Quality Health Index to be launched on December 30
It is calculated based on the cumulative health risk attributable to the three-hour moving average concentrations of four air pollutants, namely ozone, nitrogen dioxide, sulphur dioxide and particulate matter (PM2.5 and PM10).
