随着工业化、城市化的发展，城市大气污染对环境和人体健康的潜在影响正日益引起世界各国的普遍关注。尤其是污染物产生的健康效应评估是当前研究的热点。目前空气质量健康影响评估采用的主要方法是风险评估。完整的环境健康风险评估框架包括危害鉴别．剂量一效应关系评价．暴露评价和风险表征四个环节。作者对城市空气质量数值模拟、人口暴露、大气污染物毒理及其健康效应的研究现状分别阐述．从研究尺度．研究方法和健康效应的量化指标角度剖析了目前研究存在的局限性．提出未来研究的趋向及需重点解决的问题。 |

At present, air pollution draws attention of many researchers and officials from all countries to the latent impacts to human health in the world, along with the development of industrialization and urbanization. Study focus is to assess health effects of exposure to pollutants. Recently health risk assessment of air pollution is being developed at home and abroad. The full risk assessment process includes identification of pollutant concentration,exposure assessment, dose and effect assessment and expression of human health risk. The authors introduce research progress in urban air quality simulation, human exposure, air pollutant toxicology and health effect, and GIS operation in health risk assessment in recent years. Having analysed existing researches, the authors find some research limits, including： 1. Research scale are restricted to small regions, and data from limit inspect stations can＇t assess broad regions, such as megapolis; 2. Applied methods usually are qualitative although some are semi-quantitative assessment on the basis of WHO air quality health effect standard; 3. Indexes of human effect mainly are morbidity and mortality, and seldom research touches on health risk of exposed population; 4. Some researches focus on conventional pollutants health effect in short term, and little involve comparatively sensitive traffic pollutant health effect. In order to serve population, future research should concentrate on simulating microscopic urban air quality, structuring quantitative assessment based on exposure-dose relationship and developing long-term pollutant health effect models according to actually absorbed dose. |
