| 摘 要： | 本文基于对室外烟雾箱实验,探讨了SO_2的转化机制及影响SO_2转化的因素,由此并借助于烟团模型,建立了SO_2转化和硫酸盐气溶胶细粒子生成的数值模型,用于估算从排放源排入大气的SO_2浓度及其转化成硫酸盐细粒子的浓度以及它们的空间分布,与实测结果相比,两者有较好的一致性.同时指出,由于大气中细粒子(粒径小于1μm)可通过人体呼吸进入并沉积在肺泡中而对健康有不利影响,从而说明研究大气中细粒子污染的迫切性.

| Abstract: | Based on outdoor smog chamber experiments, the transformation mechanism for SO2 and sulfate and the factors which have influence on SO2 transformation are described . A numerical model has been established which incorporates the puff model and the equations for SO2 transformation and sulfate aerosol formed , and it is used to estimate regional distribution of sulfur dioxide and sulfate concentrations. The simulation results have shown consistent with the measurements from field monitoring. Because sulfate aerosol (particles diameters with smaller than 1um) could be deposited in the pulmonary alveoli by man's breath and persent a greater health hazard than SO2, it is urgent to study smaller particles pollution . |
