世衛組織：地球上90%的人呼吸被污染的空氣

Nine out of 10 people on the planet are breathing polluted air, the World Health Organization says, with indoor pollution a major and generally unrecognized problem.

The latest report by the WHO says air pollution kills 7 million people every year with marginalized populations in such places as Africa and Asia, who bear the brunt.

Dirty air, both in and out of doors, leads strokes, heart disease, lung cancer and such chronic respiratory diseases as asthma.

While most people associate air pollution with outdoor sources such as factory emissions and cars, the WHO report says indoor pollution causes close to 4 million deaths a year.

"Three-billion people around the st half of the world global still relying on very polluting fuels for cooking or heating or lighting the house," Dr. Neira says.

They include kerosene, wood, and other solid fuels instead of cleaner sources such as electricity and gas.

Dr. Neira announced WHO will convene the first-ever global conference on air pollution at the end of October in Geneva, looking to come up with interventions and solutions.世界衛生組織說，世界上90%的人呼吸着污染空氣，室內污染是一個通常不爲人所注意的大問題。

世衛組織在新公佈的一份報告中說，空氣污染每年導致700萬人死亡，其中大多數是非洲和亞洲的弱勢羣體。

室內和室外的污染空氣導致中風、心臟病、肺癌和哮喘等慢性呼吸道疾病。

世衛組織的報告說，大多數人認爲空氣污染來自工廠和汽車排放等外部污染源，但是室內污染每年造成將近400萬人死亡。

世衛組織官員尼拉博士說：“全世界有佔世界人口將近一半的30億人仍然依賴造成嚴重污染的燃料來做飯、取暖或室內照明。”

他們使用煤油、木柴和其它固體燃料，而不是更清潔的電力和天然氣。

尼拉博士宣佈，世衛組織將於10月底在日內瓦召開第一屆空氣污染的全球會議，希望能找到改變現狀的解決方案。
