生活环境是由外环境和个人在不同地点的微环境组成,每个活动地点(微环境)暴露空气污染物有一定的差异。环境污物暴露健康效应评估的关键问题是对日常活动中不同微环境暴露剂量进行评估。暴露剂量取决于暴露时间、肺通气率以及暴露的水平,因此,对个人暴露环境污染物进行科学评估 Living environment is composed of external environment and individual micro-environment in different locations, each activity site (micro-environment) exposure to air pollutants have some differences. Environmental Contaminants The key issue in assessing the health effects is the assessment of the different microenvironmental exposures to daily activities. The exposure dose depends on exposure time, lung ventilation rate, and exposure level, and therefore, a scientific assessment of the individual exposure to environmental contaminants
