最近发表在美国《环境科学技术》杂志 (N0 .5 )上的一份流行病学调研报告称 ,长期暴露于细颗粒物与肺癌、心血管疾病有统计意义上的关联。该项研究调查人群多达 5 0万人 ,追踪时间长达 1 6年。发现城市大气中细颗粒物每增加 1 0μg/m3,肺癌死亡率增加 8% ,心肺疾病死亡率增加 6 A recent epidemiological study published in the U.S. Environmental Science and Technology magazine (N0.5) reported that there was a statistically significant association between long-term exposure to fine particles and lung cancer and cardiovascular disease. The study investigated as many as 500,000 people and traced as long as 16 years. For each additional 10 μg / m3 of fine particulate matter in the urban atmosphere, the mortality rate for lung cancer increased by 8% and the mortality rate for cardiopulmonary diseases increased by 6%
