市PM2.5污染特征及来源分析
摘 要
市作为中原腹地城市，省南部的经济中心城市，位于晋冀鲁豫四省交界腹地，由于其产业结构和城市发展问题，市是全国大气严重污染的城市之一。其中，大气污染最重要的指标PM2.5近年来更是连续严重超标，对居民的正常生活带来了危害，对人体健康造成危害。本文主要是根据国外PM2.5的研究现状对PM2.5阐明概念；利用市的气象数据对市PM2.5指数的现状呈现特征和PM2.5的质量浓度分布进行分析研究和讨论，得出市PM2.5的昼夜 变化特征和季节变化特征；用主成分分析法分析市PM2.5的来源组成；用相关性分析法分析PM2.5与SO2的相关性；说明其对人们生活带来的危害及对人体产生的危害；根据市的产业结构现状和城市发展的当前问题，拟提出针对PM2.5危害的防治对策的可行建议。
关键词：市 PM2.5 质量浓度 防治对策
