摘要
以中国西部某典型工业园区为研究对象,通过对不同土地利用类型的人群活动模式暴露参数进行调研,结合工业园区氮氧化物(NO x)排放的空间分布预测,估算不同土地利用类型下的NO x情景暴露量,进而识别园区周边NO x高暴露区。研究结果显示,在引入土地利用类型情景暴露参数后,园区周边NO x高污染区与NO x高暴露区的空间分布存在一定差异。相比占标率而言,基于土地利用类型的NO x情景暴露量可以更加准确地描述由于暴露导致的区域人群健康风险,弥补现有规划环境影响评价对区域健康风险预测的不足,为大气环境管理提供科学依据。
A certain typical industrial park in western China was taken as the research object and the exposure parameters of the crowd activity patterns of different land-use types were studied.Combined with the prediction of the spatial distribution of nitrogen oxides(NO x)emissions in the industrial park,the NO x exposure quantity under different land-use scenario was estimated to indentify high NO x exposure area.The results showed that after dating the exposure parameters of the land-use scenario,there was a certain difference in the spatial distribution of high NO x pollution areas and NO x high exposure areas around the industrial park.Compared with the ratio of NO x concentration to standard,the NO x scenario exposure quantity based on the land-use types could more accurately describe the health risks of the regional population due to exposure.The existing overall planning environmental impact assessment was insufficient to predict regional health risks,and the exposure scenario based identification technique could provide a scientific basis for atmospheric environmental management.
