Abstract
Air pollution, both indoor and outdoor, has been found to be related to serious adverse health effects. Accurate estimation of air pollution exposure has become very important to suggest proper air pollution control policies and to further assess the effectiveness of these policies. In many instances, personal exposures have been found to be greater than concentrations measured at fixed site monitoring stations. As people spend most of their time indoors particularly during harsh weather conditions, it is necessary to consider indoor air quality in exposure assessment studies. The current paper focuses on the importance of personal exposure assessment based on spatial and temporal activity patters both indoors and outdoors.
Highlights
A primary goal of air pollution control policy is to reduce, or ideally eliminate adverse effects on human health
It is well known that health risk assessment is most effective as a policy tool when it is linked to realistic exposure assessment, rather than to environmental concentrations
This is because exposure is likely to be more closely related to health effects experienced by individuals
Summary
A primary goal of air pollution control policy is to reduce, or ideally eliminate adverse effects on human health. Many study designs used in time series studies of health effects, and in assessing the health benefits of emission reductions, relied on air pollution concentrations measured at fixed measurement stations, usually at urban background sites, to define exposure of the study populations [2]-[4]. It is well established by extensive modeling and measurement studies that.
