　　【化工仪器网政策标准】大气中的颗粒物是指大气环境中存在的各种固态和液态颗粒物的总称，常见的灰尘、霾都属于大气颗粒物。大气颗粒物是大气污染的主要污染物，也是雾霾的主要成因，其中可吸入颗粒物即PM2.5和PM10，不仅影响环境，更会对人体健康造成极大的影响。随着近些年我国对环境重视程度的提升，大气颗粒物成为了空气污染治理的主要项目之一，受到了环保部门的“重点关照”。

　　我国大气颗粒物具有两大特点：来源复杂、成分繁多。因此要有针对性的对颗粒物进行监控并采取治理措施，就需要对颗粒物的来源和成分进行解析。为贯彻落实《打赢蓝天保卫战三年行动计划》，规范环境空气颗粒物来源解析工作，进一步提高监测结果的科学性和可比性，生态环境部组织对《环境空气颗粒物来源解析监测技术方法指南(试行)》(环办函〔2014〕1132号)进行了修订。2020年5月14日，生态环境部发布了修订后的《环境空气颗粒物来源解析监测技术方法指南》(以下简称《指南》)。

　　《指南》提供了大气颗粒物来源解析监测工作所涉及的技术方法，主要包括污染源样品采集、环境受体样品采集、样品管理、颗粒物监测项目选择与分析方法，以及贯穿颗粒物样品采集、保存、制备和分析等全过程的质量保证与质量控制措施，适用于环境空气颗粒物来源解析相关的监测工作。

　　《指南》罗列了几种颗粒物元素分析的方法，包括电感耦合等离子体发射光谱法，电感耦合等离子体质谱法、X射线荧光光谱法、原子荧光光谱法；分析颗粒物水溶性离子的方法有离子色谱法、原子吸收分光光度法；分析颗粒物总元素碳和有机碳，则可利用有机碳/元素碳气溶胶分析仪；分析颗粒物中他标识物如多环芳烃，可利用液相色谱法或气相色谱法。

　　《指南》内容详尽，各地看根据所采用的环境空气颗粒物来源解析方法，结合本地区重点污染源排放清单、污染源颗粒物特征组分以及监测技术的可行性，科学合理地选择适合当地的监测技术方法。

　　2020年是打赢“蓝天保卫战”三年行动计划的收官之年。《指南》的发布，有利于我们在此关键时期，方向不变，力度不减地继续加强空气环境监测，全力以赴打好污染防治攻坚战。
