PM_(2.5)对人群健康影响的流行病学研究进展

Progress on Epidemiological Study of PM_(2.5) Effect to Human Health

随着科技的不断进步,雾霾现象频繁发生,雾霾中主要以PM_(2.5)为主,因此人类长期或短期暴露于高浓度的PM_(2.5)可能对人类的健康有一定的影响,这不仅是工业生产和环境卫生的热点社会问题,更是国内外科学研究的焦点问题。大量研究表明,PM_(2.5)可导致呼吸系统、心血管系统、免疫系统和生殖系统等出现功能障碍,甚至炎症的发生,严重可导致死亡。本文综述了PM_(2.5)的化学组成、来源、研究方法和对人群健康的影响等。

With the continuous progress of science and technology,haze phenomenon occurs frequently,PM_(2.5)was the main component of haze. Long-term or short-term exposure to high concentrations of PM_(2.5)may have a certain impact on human health,which was not only a hot social issue on industrial production and environmental health,but also a focus of research among domestic and foreign scientists. Numerous studies have shown that PM_(2.5)can cause respiratory,cardiovascular,immune and reproductive systems,and even can cause inflammation; severe exposure can lead to death. This article reviewed the chemical composition and sources of PM_(2.5),research methods and its effect on human health.
