摘要
目的根据区域大气污染源分布研究确定区域大气污染物历史暴露浓度,确定健康调查工作范围。方法用多源扩散数学模型计算健康调查区域内的大气污染物历史暴露浓度。结果根据计算的历史暴露浓度绘制污染物等值浓度图,为环境卫生健康调查工作提供图文并茂的环境状况,并对如何准确利用数学模型进行探讨。结论利用多源扩散数学模型是研究健康调查区域内大气污染物历史暴露浓度的一种可行方法。
Objective To study distribution of air pollution source , determine the historical exposure concentration of air pollution in the region, and assure the work scope of health investigation. Methods The air pollutant exposure concentration in history were calculated with the multi - source proliferation mathematical model. Results According to the computation of historical exposure concentration, pollutants equivalent concentration chart were drawn, which provided the abundant and elegant environmental conditions for the Environmental Health Survey. Conclusion It is an effective method to use multi - source proliferation mathematical model for studying the pollutants exposure concentration in atmosphere of the health survey region in history.
