许多流行病学和毒理学研究表明大气颗粒物与人群死亡率和发病率明显相关。超细颗粒物是大气颗粒物的重要组成成分,与呼吸系统和心血管系统疾病密切相关。本文综述了超细颗粒物的分布特征及其组成成分,综合大气超细颗粒物与人群健康效应的流行病学及毒理学资料,以获取超细颗粒物健康效应的可能机制,并总结超细颗粒物的研究方向,为大气中超细颗粒物污染的健康危险度评价提供依据。
Many epidemiological and toxicological studies have shown that atmospheric particulate matter is significantly associated with population mortality and morbidity. Ultrafine particles are an important component of atmospheric particles and are closely related to respiratory and cardiovascular diseases. This paper summarizes the distribution and composition of ultrafine particles, synthesizes the epidemiological and toxicological data on the effects of ultrafine particles and population health on the health effects of ultrafine particles, and summarizes the research on ultrafine particles Direction, provide the basis for the evaluation of the health risk of airborne ultrafine particle pollution.
