摘 要:被动扩散技术以其低成本、操作简单、空间覆盖率较高等优点已在西方国家广泛应用于环境空气质量监测与调查,辽宁省环保局通过欧盟项目引进,本技术在葫芦岛市环境空气质量监测应用有4年时间。依据4年环境空气被动扩散管监测基础数据,分析了解葫芦岛市城区大气中NO_2时空分布特征:高浓度值出现在交通区,季节上呈现春季明显低于其它季节。Passive diffusion technique has advantage of low cost, easy to operate and space cover wide was widely used in west countries for environment air monitoring and survey. Huludao municipal environment protection monitoring center introduce the diffuse pipe and the monitoring analysis technique from EEC by Liaoning province EPB to monitor the nitrogen dioxide in air has been four years. The article analyzed Huludao area the nitrogen dioxide space time distributing character in accordance with basic data of monitoring by passive diffuse pipe in last 4 years and came to the conclusion that high concentration nitrogen dioxide appeared in traffic section and springtime lower than others seasons.
