　　【化工仪器网政策标准】生态环境是指影响人类生存与发展的水资源、土地资源、生物资源以及气候资源数量与质量的总称，关系到社会和经济持续发展的复合生态系统。生态环境与人类的活动密切相关，影响着人类的生活和生产。

　　近年来，随着我国经济的发展以及人口的迅速增长和生产力的发展，科学技术的突飞猛进，工业及生活排放的废弃物不断地增多，从而使大气、水质、土壤污染日益严重，自然生态平衡受到了猛烈的冲击和破坏，许多资源日益减少，并面临着耗竭的危险，水土流失，土地沙化也日趋严重，粮食生产和人体健康受到严重威胁，所以，维护生态平衡，保护环境是关系到人类生存、社会发展的根本性问题。

　　环境保护就是运用环境科学的理论和方法，在更好地利用自然资源的同时，深入认识污染和破坏环境的根源及危害，有计划地保护环境，预防环境质量恶化，控制环境污染，促进人类与环境协调发展，提高人类生活质量，保护人类健康，造福子孙后代。

　　近日，中国环境监测总站现启动2021年生态环境监测类标准制修订立项建议征集工作，征集范围包括配套质量标准、排放标准等管理要求和支撑污染排放精细管控两大类，其中包括大气颗粒物组分监测、来源解析、大气光化学监测相关的技术方法；固定污染源和环境空气氨监测相关的技术方法；固定污染源和环境空气VOCs监测相关的技术方法；二噁英自动采样技术；现场、快速、自动监测相关的技术。

　　其中，VOCs是挥发性有机化合物(volatile organic compounds)的英文缩写。根据世界卫生组织(WHO)的定义，VOCs(volatile organic compounds)是在常温下，沸点50℃至260℃的各种有机化合物。在我国，VOCs是指常温下饱和蒸汽压大于70 Pa、常压下沸点在260℃以下的有机化合物，或在20℃条件下，蒸汽压大于或者等于10 Pa且具有挥发性的全部有机化合物。

　　二噁英通常指具有相似结构和理化特性的一组多氯取代的平面芳烃类化合物，属氯代含氧三环芳烃类化合物，包括75种多氯代二苯并一对一二噁英和135种多氯代二苯并呋哺，缩写为PCDD/Fs。研究为充分的有毒二噁英为2位、3位、7位、8位被氯原子取代的17种同系物异构体单体(congenor)，其中，2，3，7，8-四氯二苯并-对-二噁英(2，3，7，8一TCDD)是目前所有已知化合物中毒性强的二噁英单体( 经口LDSO按体重计仅为1pug/kg)，且还有极强的致癌性( 致大鼠肝癌剂量按体重计10μg/g)和极低剂量的环境内分泌干扰作用在内的多种毒性作用。这类物质既非人为生产、又无任何用途，而是燃烧和各种工业生产的副产物。目前，由于木材防腐和防止血吸虫使用氯酚类造成的蒸发、焚烧工业的排放、落叶剂的使用、杀虫剂的制备、纸张的漂白和汽车尾气的排放等是环境中二噁英的主要来源。

　　此次，中国环境监测总站征集2021生态环境监测类标准制修订立项，涉及了VOCs、二噁英等，表示了我国对于环境中有害物质监测的重视，并且进一步推进加强了生态环境监测标准体系建设。

　　为做好2021年生态环境监测标准制修订立项建议，中国环境监测总站受生态环境部生态环境监测司委托，现启动2021年生态环境监测类标准制修订立项建议征集工作，有关事项通知如下：

　　一、征集范围
