摘要
以往的研究表明 ,细粒子富集了大气气溶胶中的大部分有害物质 ,它可以进入呼吸系统并沉积于肺泡 ,严重影响人类健康 ,并且是导致环境恶化的重要因素 ,因此 ,对细粒子的研究越来越得到人们的重视。文章介绍了纽约市PM2 .5研究的背景、规划 ,以及依规划制定的科学策略和提出的设想 ,详述了观测点的选择、采用的方法 ,并介绍了已有的初步结果 ,为我国同类研究提供参考。
From the previous research result it can be found that fine particle congregates most of the nocuous matter of aerosol. These matters can enter into respiration system of humanbeing, and be deposited in the alveolus. Fine particles seriously affect people's health, and make environment even worse. Experts have attached great importance to the research in this field. The background,project,science policy and problem of the PM 2.5 research in New York City are given. The measurement sites and some already acquired primary results are particularly introduced in order that all these can provide some help to similar research in China.
