Scientists have revealed that air pollution may be responsible for a significant reduction in intelligence. Research conducted for the World Health Organization (WHO) in China showed that air pollution was responsible for notable falls in student test scores for languages and arithmetic. The Chinese study is called, "The impact of exposure to air pollution on cognitive performance". It was published in a journal called, "Proceedings of the National Academy of Sciences". The study took place over a period of four years. Researchers analyzed verbal and arithmetic tests taken by 20,000 people of all ages. They said: "Polluted air may impede cognitive ability as people become older."

科學家透露空氣污染或許導致智力顯著下降。中國世界衛(wèi)生組織（WHO）研究表明空氣污染導致學生語言和算術測試成績顯著降低。這項中國研究名為《空氣污染對認知表現(xiàn)的影響》。被研究發(fā)表于《Proceedings of the National Academy of Sciences》期刊上。該研究為期4年。研究人員對所有年齡段中的兩萬人的語言和算數(shù)測試進行分析。他們表示：“隨著年齡增長，空氣污染會阻礙人們的認知能力。”

Researchers say their study is a warning to the rest of the world, especially to those who live in cities. The WHO says over 91 per cent of the world population live in areas with toxic air. Air pollution is currently the fourth highest cause of deaths worldwide. The researchers discovered that the longer people were exposed to polluted air, the greater was the damage to their intelligence. They equated the impact of air pollution to losing a year's worth of education. For those aged over 60, this could be the equivalent of several years of lost education. Researcher Dr Xi Chen warned: "There is no shortcut to solve this issue. Governments really need to take concrete measures to reduce air pollution."

研究人員表示他們的研究是對世界，尤其是那些生活在城市里的人的一種警告WHO表示超過91%的世界人口，他們所居住的地方空氣都是有毒的。目前空氣污染是全球第四大死因。研究人員發(fā)現(xiàn)人們暴露在污染空氣中的時間越長，他們的智力就會受到越嚴重的傷害。他們將這種空氣污染的影響等同于一年的教育缺失。對那些60歲以上的人而言，這種影響相當于好幾年的教育缺失。研究人員陳西警告稱：“解決這個問題刻不容緩。政府真的需要采取具體措施減少空氣污染。”
