Air pollution is shortening your life.空氣污染正在縮短您的生命。

• Air pollution is shortening your life.

Months, and sometimes years, are being shaved off life expectancy, according to a new study.

Outdoor air pollution — fine particulate matter from sources like coal-fired power plants, truck tailpipes, wildfires and dust storms — reduces the worldwide average life expectancy at birth by one year, researchers found. The average Egyptian loses 1.9 years; the average Indian, 1.5 years. Above, a scene in New Delhi last year.

Many of the sources of outdoor air pollution are tightly linked to greenhouse gas emissions, suggesting that moving to cleaner sources of energy might deliver public health dividends.

Indoor air pollution — for example, from cooking with wood, charcoal or animal dung — can also be devastating. In South Asia, the researchers found, it reduced life expectancy by an additional 1.2 years.

•空氣污染正在縮短您的生命。
一項新的研究顯示，幾個月，有時是幾年，正在減少預期壽命。
研究人員發現，室外空氣污染 - 來自燃煤發電廠，卡車尾氣管，野火和沙塵暴等來源的細顆粒物質 - 將全球出生時的平均預期壽命降低了一年。 埃及人平均損失1。9年; 平均印度人，1。5年。 上圖是去年新德里的一個場景。
許多室外空氣污染源與溫室氣體排放密切相關，這表明轉向更清潔的能源可能會帶來公共衛生紅利。
室內空氣污染 - 例如，用木頭，木炭或動物糞便烹飪 - 也可能是毀滅性的。 在南亞，研究人員發現，它將預期壽命再降低了1.2年。Google翻譯
