世界卫生组织下属的国际癌症研究机构10月发布一份报告,将大气污染列为人类致癌因素之一。大气污染中的主要成分——颗粒物也被列为致癌因素。根据致癌程度的不同,专家将致癌性物质分为4类:致癌、可能致癌、未知和可能不致癌。报告说,有足够证据表明,大气污染会导致肺癌,增加膀胱癌发病率。最新数据显示,2010年全球由大气污染导致的肺癌死亡人数高达22.3万。该机构指出,虽然不同地区大气污染组成和人们在空气中暴露程度存在很大区别,但这个
The International Agency for Research on Cancer (IARC), affiliated with the World Health Organization, released a report in October listing air pollution as one of the human carcinogens. The main component of air pollution - particulate matter has also been classified as carcinogenic factors. Depending on the degree of carcinogenicity, experts categorize carcinogenic substances into four categories: carcinogenic, potentially carcinogenic, unknown, and possibly carcinogenic. The report said there is enough evidence that air pollution causes lung cancer and increases the incidence of bladder cancer. The latest data show that in 2010 the global population of lung cancer caused by air pollution as many as 223,000. The agency pointed out that although the composition of air pollution in different regions and people in the air there is a big difference in the level of exposure, but this
