  1. 空氣污染指數總覽An Overview of Air Pollution Index 香港特別行政區政府環境保護署The Government of the Hong Kong Special Administrative RegionEnvironmental Protection Department

  2. 甚麼是空氣污染指數 ?What is the Air Pollution Index (API) ? • 以一個簡單的方法來表達空氣污染的程度。 A simple way of describing air pollution levels • 根據數種污染物在空氣中的濃度而轉化為一個介乎0至500的數值。 Converts air pollution data from several types of pollutants into a value ranging from 0 to 500 • 空氣污染物包括:二氧化氮、二氧化硫、臭氧、一氧化碳和可吸入懸浮粒子 Pollutants are nitrogen dioxide, sulphur dioxide, ozone, carbon monoxide and respirable suspended particulates

  3. 空氣污染指數是如何計算及公佈?How is the API Calculated and Reported? • 每小時會公佈即時的「一般」和「路邊」空氣污染指數。Report the real-time general and roadside APIs hourly • 與空氣污染管制條例下的空氣質素指標互相比較。 Calculated by comparing the measured concentrations of the major air pollutants with Air Quality Objectives (AQOs) established under the Air Pollution Control Ordinance • 先會根據濃度計算出這５種污染物各自的指數，然後選取當中最高的數值作為該小時的空氣污染指數。 An index is calculated for each of the five pollutants and the highest index is reported as the API of that hour

  8. 應該參考哪一個空氣污染指數？Which API should I refer to? • 對於大部份市民來說，因為「一般」空氣污染指數代表了我們大部份時間所接觸的空氣污染情況，所以較有參考價值。 For most of us, the general API is more relevant as it represents the air pollution that we are exposed to for most of the time • 土地用途相仿的地區會有相近的空氣質素水平。因此可以參考附近土地用途相似的地區內的監測站所錄得的空氣污染指數。 Areas of similar land uses will have similar air pollution levels. You may refer to the API measured in an area nearby

  9. 「路邊」空氣污染指數又如何？What about the roadside API? • 對大多數市民來說，他們每天只短暫停留在繁忙的道路旁邊，「路邊」空氣污染指數對他們的意義相對較小。 For most people, the roadside API will be less relevant as they spend only a short period of time each day at such locations • 而對那些需要經常在車輛繁忙的街道上連續停留數小時以上的人士來說，「路邊」空氣污染指數則較為重要。 The roadside API is of more interest to those who spend several hours continuously each day in busy streets

  14. 如何能夠取得空氣污染指數的資料? How Can I Get the API Information? • 環境保護署網址: http://www.epd.gov.hk website: http://www.epd.gov.hk • 空氣污染指數互動語音熱線: 2827 8541 API Interactive Voice Recording Hotline: 2827 8541 • 電台及電視台 Radios and televisions

  15. 學校如何獲取最新的空氣污染指數或指數預報﹖ How can Schools Get Access to the Latest API or its Forecast? • 環境保護署（環保署）網頁：www.epd-asg.gov.hk/cindex.php Environmental Protection Department (EPD)’s website: www.epd-asg.gov.hk/eindex.php • 空氣污染指數熱線（熱線號碼：2827 8541） EPD’s “API Hotline” on 2827 8541. • 當空氣污染指數達到甚高或嚴重水平時，教育局在收到環保署的通知後，會把有關資訊傳遞致學校。 When the API reaches the very high or severe level, EDB will relay the relevant information to schools upon receiving the notification from EPD.

  16. 學校可否知悉未來一天的空氣污染指數預報資料﹖學校可否知悉未來一天的空氣污染指數預報資料﹖ Will API Forecast for the Next Day be Available? • 環保署提供未來24小時(當天下午四時至翌日下午四時)的空氣污染指數預報。 EPD has been providing API forecast for the next 24 hours (normally covering the period of 4pm of the day to 4pm of the next day )daily . • 環保署網頁： www.epd-asg.gov.hk/cindex.php EPD’s website: www.epd-asg.gov.hk/eindex.php

  17. 學校應參考哪個一般空氣質素指數監測站的數據?學校應參考哪個一般空氣質素指數監測站的數據? Which General API Station Should Schools Refer to? • 一般空氣質素除了受本地污染源影響外，亦會受到區域性空氣污染及氣象因素影響。 The general air quality in HK is affected by regional air pollution and weather conditions apart from local emission sources. • 當有個別一般空氣質素監測站的空氣污染指數超過100時，表示本港當時的整體氣象條件不利污染物擴散，或正受到大範圍的區域性空氣污染影響，全港其他地區的空氣污染亦有可能會在當日內達到較高水平。 When the API at any General Station exceeds 100, it indicates that the weather conditions do not favour the dispersion of air pollutants or Hong Kong is being affected by regional pollution. It is possible that the air pollution level in other parts of the territory may also reach higher levels on the same day. • 當有一般空氣質素監測站的空氣污染指數超過100時，全港各區的學校應要留意並須採取適當的預防措施。 When API at any General Station exceeds 100, schools should be alert and take necessary precautionary measures as appropriate.

  18. 學校需否參考路邊空氣污染指數 ? Should Schools Refer to the Roadside API? • 學校應避免安排學生在貼近交通繁忙道路（例如雙線雙程或更多行車線的道路）的地點進行體力消耗活動。因此，在大部份情況下，學校只需參看一般空氣污染指數。 Schools should avoid arranging students to have strenuous physical activities at places close to busy roads (such as roads of dual traffic with two lanes or more on each side of the road). Therefore, under most circumstances, schools should refer to General API. • 若學生進行運動的地點貼近繁忙路旁，而運動場地與道路之間沒有阻隔物防止汽車污染物直接進入場地，便需參考路邊空氣污染指數。 Schools should refer to Roadside API if the playground for physical activities is close to busy roads and is not shielded from direct impact of vehicle emissions by any forms of physical barriers.

  19. 學校需否參考路邊空氣污染指數 ? (續) Should Schools Refer to the Roadside API? (Cont’) • 一般而言，在下列情況下的運動地點，不需參考路邊空氣污染指數： In general, schools do not need to refer to Roadside API if • 運動地點與道路的距離不少於15米；或 the separation between the playground and the busy road is not less than 15m; or • 運動地與道路之間有建築物（如校舍外牆）的阻隔；或 the playground and busy road is separated by buildings (such as the external walls of a school building); or • 運動地與道路之間有不少於2.5米高的阻隔物（如圍牆），而與道路的距離不少於8米。 the playground and busy road is separated by physical barrier of not less than 2.5m in height (such as a fence) and the distance between the playground and the road is not less than 8m.

  20. 若學校需參考路邊空氣污染指數，應參考哪個路邊監測站的數據? For Those Schools that Need to Refer to Roadside API, Which Roadside Station Should they Refer to? • 環保署現時設有三個路邊監測站，分別位於旺角、中環及銅鑼灣，均是設於市區常見的交通繁忙地區的路旁。這些路邊監測站的數據，已能代表繁忙路旁的空氣質素情況。 The EPD has set up three roadside stations at Mong Kok, Central and Causeway Bay, which are all sited at roadside in built-up urban areas. The data collected from these stations are representative of the roadside air quality in areas with heavy traffic. • 當有任何一個路邊監測站的空氣污染指數超過100時，表示本港當時的整體氣象條件不利路邊污染物擴散。其他地區交通繁忙路旁的空氣污染亦可能達到較高的水平。 When the API at any roadside station exceeds 100, it indicates that the weather conditions do not favour the dispersion of air pollutants at the roadsides and that the pollution level at roadsides in different parts of the territory may also reach higher levels. • 當有任何一個路邊監測站的空氣污染指數超過100時，需參考路邊空氣污染指數的學校應要留意並須採取適當的預防措施。 When the API at any roadside station exceeds 100, those schools that need to refer to Roadside API should be alert and take necessary precautionary measures as appropriate.
