空气污染一直是世界各国面临的一个问题。世界卫生组织观察到,在全球死亡人数中,每9例中就可能有1例与暴露在室内外空气污染相关。建设智慧城市、改善废弃物管理、使用清洁能源、建立可持续工业实践都可以改善全球空气质量,但我们如何才能测量空气质量呢?澳大利亚标

准协会近期完成了两项解决空气质量标准的修订:

• AS 3580.9.9:2017 环境空气取样和分析方法 9.9: 悬浮颗粒物的测定——低容量PM10取样器——重量分析法

• AS 3580.9.10:2017 环境空气取样和分析方法 9.10:悬浮颗粒物的测定——低容量PM2.5取样器——重量分析法 PM10与PM2.5都是在全球范围内引发显著社会关注的污染物。这两种颗粒物可通过呼吸进入人体,进而引发严重公共健康问题。

AS 3580.9.9和AS 3580.9.10规定了PM10和PM2.5的检测方法,以评估空气质量。对这些澳大利亚标准文件的修订旨在使其与其他现行颗粒物标准文件保持一致。EV-007技术委员会--空气检测方法,负责本项目。针对此次修订,技术委员会主席弗兰克·弗利尔(Frank Fleer)先生认

为:“EV-007技术委员会负责维护准确可靠的测量这些污染物的标准。对世界范围内的许多家庭来说,空气污染既是社会关切,也是重大健康问题。“因此,我们认为的有必要对这些标准进行修订以反映现代的品质。

 

Have you ever wondered how to tell if air is clean

 Air pollution has long been a problem in nations all around the world. The World Health Organization has observed that up to 1 in 9 of total global deaths are linked to exposure to indoor and outdoor air pollution.1 Smart cities, better waste management, clean energy and sustainable industrial practices should all lead to improvements in air quality around the world, but how do we measure the quality of the air? Standards Australia recently completed revisions of two standards addressing air quality:

   • AS 3580.9.9:2017, Methods for sampling and analysis of ambient air, Method 9.9: Determination of suspended particulate matter—PM10 low volume sampler— Gravimetric method

• AS 3580.9.10:2017, Methods for sampling and analysis of ambient air, Method 9.10: Determination of suspended particulate matter—PM2.5 low volume sampler— Gravimetric method Particulate matter PM10 and PM2.5 are pollutants that present a significant community concern worldwide. These forms of particulates are respirable and present major public health issues.

AS 3580.9.9 and AS 3580.9.10 set out methods for detecting PM10 and PM2.5 in order to assess air quality. These Australian documents were revised to make them consistent with other contemporary particulate matter standards. Technical committee EV-007, Methods for Examination of Air, was responsible for this project. Chair of the committee, Mr Frank Fleer, commented on the revisions. “EV-007 takes its responsibility in maintaining accurate and reliable standards for the measurement of these pollutants very seriously. It’s both an environmental concern and a major health issue affecting many communities worldwide. “Consequently we felt it was necessary to update these documents to reflect modern quality
