   為貫徹《環境保護法》和《大氣污染防治法》,促進環境空氣顆粒物來源解析研究工作標準化、規范化和業務化,生態環境部組織制定了《開放源揚塵顆粒物采樣技術規范(試行)》國家環境保護標準。目前,標準編制單位已完成了標準的征求意見稿。

 
  In order to implement the Environmental Protection Law and the Air Pollution Prevention and Control Law and promote the standardization,standardization and professionalization of the research on source apportionment of ambient air particulate matter,the Ministry of Ecology and Environment has organized and formulated the National Environmental Protection Standard of the Technical Specification for Sampling Dust Particulate Matter from Open Sources(Trial Implementation).At present,the standard compilation unit has completed the draft of the standard for consultation.
 
  揚塵源是當前我國城市環境空氣顆粒物的重要來源之一,可分為土壤揚塵、道路揚塵、施工揚塵、堆場揚塵和二次揚塵等。科學、規范地開展揚塵樣品采集,構建揚塵源的成分譜,直接關系到環境空氣顆粒物來源解析結果的精準性以及不同城市之間的可比性。由于缺乏揚塵采樣相關的標準,各地的揚塵采樣方法不統一,影響源解析監測結果的科學性和可比性。因此有必要開展相關研究,建立揚塵采樣的標準方法,供各地在源解析工作中參考使用。
 
  Nowadays,dust source is one of the important sources of air particulate matter in urban environment in China.It can be divided into soil dust,road dust,construction dust,stack dust and secondary dust.To collect dust samples scientifically and normatively and to construct the composition spectrum of dust sources is directly related to the accuracy of the source apportionment results of ambient air particulate matter and the comparability between different cities.Due to the lack of relevant standards for dust sampling,the sampling methods are not uniform,which affects the scientificity and comparability of source analysis monitoring results.Therefore,it is necessary to carry out relevant research and establish a standard method of dust sampling for reference in source analysis.
 
  我國目前已發布源解析技術路線、源解析技術指南、源解析監測技術指南以及一系列相關的顆粒物組分監測標準,已初步建立了顆粒物源解析技術體系。然而我國源解析技術體系還缺少污染源(固定源、移動源和開放源)采樣相關標準規范。
 
  At present,China has published the technical route of source apportionment,the technical guide of source apportionment,the technical guide of source apportionment monitoring and a series of related monitoring standards for particulate matter components,and has initially established the technical system of source apportionment of particulate matter.However,the technical system of source analysis in China still lacks relevant standards and specifications for sampling of pollution sources(fixed source,mobile source and open source).
 
  本標準規定了開放源揚塵顆粒物的采樣布點、現場采樣方法、采樣設備的技術指標、采樣的質量保證等技術要求,適用于環境空氣顆粒物來源解析工作中開放源揚塵顆粒物的采樣。
 
  This standard stipulates the technical requirements of sampling points,field sampling methods,technical specifications of sampling equipment and quality assurance of sampling for open source particulate matter.It is suitable for sampling open source particulate matter in source apportionment of ambient air particulate matter.
 
  標準編制組由中國環境監測總站、南開大學、西安市環境監測站、天津市生態環境監測中心、福州市環境監測中心站相關技術人員組成。
 
  The Standard Compilation Group is composed of relevant technical personnel of China Environmental Monitoring Station,Nankai University,Xi'an Environmental Monitoring Station,Tianjin Ecological Environment Monitoring Center and Fuzhou Environmental Monitoring Center Station.
 
  本標準引用的文件主要有《HJ/T 166土壤環境監測技術規范》、《HJ/T 393防治城市揚塵污染技術規范》、關于印發《環境空氣顆粒物來源解析監測技術方法指南(試行)》的通知(環辦函[2014]1132號)、關于發布《大氣顆粒物來源解析技術指南(試行)》的通知(環發[2013]92號)、《空氣和廢氣監測分析方法》(第四版增補版)。
 
  The main documents cited in this standard are"Technical Specification for Soil Environmental Monitoring of HJ/T 166","Technical Specification for Prevention and Control of Urban Dust Pollution by HJ/T 393","Circular on Issuance of Technical Guidelines for Source Analysis and Monitoring of Environmental Air Particulates(Trial)"(UNEP Letter[2014]1132),and Circular on Issuance of Technical Guidelines for Source Analysis of Atmospheric Particulates(Trial).(Circular[2013]92)."Air and Exhaust Gas Monitoring and Analysis Method"(Fourth Edition Supplementary Edition).
 
  其中,采樣人員根據地區土壤及氣象特點選取具有代表性的裸露地面作為采樣點。一般選擇距城市建成區10~20km的東、南、西、北4個方向的郊區。如城市主導風向與上述4個方向不同,則在主導風向的上風向增加布設至少3個點位。每個方向布設至少3個采樣點,均勻布點,點位之間距離不小于500米。采樣點周圍(500米范圍內)無其他顯著人為污染源(如廠礦、村落、商業和居民聚集區、交通道路、建筑工地等)。
 
  Among them,Samplers select representative bare ground as sampling points according to the soil and meteorological characteristics of the area.Generally,the suburbs in the east,south,West and north directions are selected 10-20 km away from the urban built-up area.If the urban dominant wind direction is different from the four directions mentioned above,at least three points will be added to the upper wind direction of the dominant wind direction.At least three sampling points are arranged in each direction,evenly distributed,and the distance between the points is not less than 500 meters.There are no other significant anthropogenic pollution sources(such as factories,mines,villages,commercial and residential areas,traffic roads,construction sites,etc.)around the sampling sites(within 500 meters).
