International Agency for Research on Cancer World Health B Organization PRESS RELEASE 17 October 2013 IARC: Outdoor air pollution a leading environmental cause of cancer deaths Lyon/Geneva, 17 October 2013 -The specialized cancer agency of the World Health Organization, the International Agency for Research on Cancer(IARC), announced today that it has classified outdoor air pollution as carcinogenic to humans( Group 1) After thoroughly reviewing the latest available scientific literature, the world's leading experts convened by the IARC Monographs Programme concluded that there is sufficient evidence that exposure to outdoor air pollution causes lung cancer( Group 1). They also noted a positive association with an increased risk of bladder cancer. Particulate matter, a major component of outdoor air pollution, was evaluated separately and was also classified as carcinogenic to humans(Group 1) The IARC evaluation showed an increasing risk of lung cancer with increasing levels of exposure to particulate matter and air pollution Although the composition of air pollution and levels of exposure can vary dramatically between locations, the conclusions of the Working Group apply to all regions of the world A major environmental health problem Air pollution is already known to increase risks for a wide range of diseases, such as respiratory and heart diseases. Studies indicate that in recent years exposure levels have increased significantly in some parts of the world, particularly in rapidly industrializing countries with large populations. The most recent data indicate that in 2010. 223 000 deaths from lung cancer worldwide resulted from air pollution The most widespread environmental carcinogen "The air we breathe has become polluted with a mixture of cancer-causing substances, says Dr Kurt Straif, Head of the IARC Monographs Section. "We now know that outdoor air pollution is not only a major risk to health in general, but also a leading environmental cause of cancer deaths
厚重的棕色云层覆盖了亚洲南部 达3公里厚、覆盖的区域达美国大陆 大小的棕色云团改变了亚洲地区气候, 北部地区降雨减少,而南部地区洪水 泛滥,从而导致粮食产量锐减。 能在3-4天内横跨大陆,卫星甚至监 测到棕云跨越太平洋影响到了美国的 西海岸。 亚洲、印度及美国产生的污染物生存 力持久,可在全球循环运动长达两周
