印度首都新德里市中心現正實行一個試驗計劃，就是啟動全國首座公共空氣淨化機。支持者表示，有關實驗有助其他新興國家的城市改善其烏煙瘴氣的情況。
有關空氣淨化機的意大利製造商Systemlife聲稱，這部重7噸的機器每小時可淨化1萬立方米空氣，並可過濾二氧化碳和氮氧化物等污染物。
這部淨化機周六放置在新德里市中心的一條繁忙街道，如果試驗成功，市區其他地方未來亦會陸續安裝。世界衛生組織(WHO)現將新德里列為全球第四個污染最嚴重的城市。
新德里市政府衛生局長夏爾馬表示，國家環保機構將會監測這部機器的表現。這部淨化機的價格約為55.1萬美元，運作原理如吸塵機，先將空氣吸入，然後再從頂部通風口送出淨化的空氣。
這部電動淨化機安裝費用全免，利用5個階段的過濾程序來淨化空氣，當中包括用電極來移除威脅健康的固體和氣體污染物。
Systemlife的印度夥伴公司總監莫迪表示：「印度幾乎所有城市，特別是新德里，都需要這部淨化機。」
Systemlife的聲明指出，該公司已在全球多個地點安裝類似的淨化機，其中26個地點在西班牙、6個在瑞士以及7個在意大利。
印度中央污染控制委員會的環境科學家薩哈說，國營的監管機構會留意這部機器最終是否成功。 ■綜合外電消息

India's Smoggy Capital Tries a Whiff of Fresh Air
India has switched on its first public air purifier in the heart of capital New Delhi as part of an experiment that backers say could help other smog-choked cities in emerging countries.
The maker of the 7-ton machine, Italy's Systemlife, claims the box-like structure can purify 10,000 cubic metres of air every hour, scrubbing out pollutants such as carbon dioxide and nitrogen oxide.
The unit, plugged in Saturday on a traffic-clogged street of central Delhi, is a pilot that could lead to more being installed in other areas of the city, ranked the world's 4th most polluted by WHO.
P.K. Sharma, the health chief of the New Delhi Municipal Council, said a state environmental agency will monitor the performance of the machine, which costs about 551,000 U.S Dollars and works like a vacuum cleaner, sucking in air and releasing its purified form from a roof vent.
The electricity-driven unit, installed free of cost, uses a 5-stage filtering process including electrodes to remove health-threatening solid and gaseous pollutants.
"Almost all Indian cities and especially New Delhi needs them," said Ritika Modi, director of the Indian partner company of Systemlife.
Systemlife has installed similar public purifiers at 26 locations in Spain, 6 in Switzerland and 7 in Italian cities, according to a statement issued by the firm.
Environmental scientist D. Saha from the Central Pollution Control Board said the state-run watchdog would also keep a check on the success or failure of the Italian unit. ■AFP
