标准范围
ISO 18400-204:2017包含使用以下方法进行土壤气体采样的指南-主动取样（吸附剂、过滤器、空气容器），以及-被动采样应用于土壤中或建筑物（底板）下方的永久或临时监测井或其他设施。它提供了以下方面的指导:-制定抽样计划；-建造监测设施；-运输、包装和储存土壤气体样品；-质量保证。ISO 18400-204:2017还提供了以下基本信息:-土壤气体动力学，以及-土壤气源识别与土壤中或建筑物下的永久或临时钻孔相关（sub？平板）。本文件涵盖的化合物是:挥发性有机化合物(VOCs)；无机挥发性化合物(例如汞、HCN)；永久性气体（即。CO2、N2、O2、CH4）。ISO 18400-204:2017未就以下方面提供指导:-风险评估和表征；-保护措施的选择和设计；-核实保护措施，但可酌情使用所述的现场调查方法；-大气或室内气体的取样；-测量从土壤进入大气的气体；-氡的监测和取样。
ISO 18400-204:2017 contains guidance on soil gas sampling using- active sampling (adsorbents, filters, air containers), and- passive samplingapplied at permanent or temporary monitoring wells or other installations in soils or underneath buildings (sub-slab).It provides guidance on:- development of a sampling plan;- construction of monitoring installations;- transport, packaging and storage soil gas samples;- quality assurance.ISO 18400-204:2017 also gives basic information about- soil gas dynamics, and- identification of soil gas sourcesrelevant to permanent or temporary boreholes in soils or underneath buildings (sub？slab).The compounds covered by this document are:. volatile organic compounds (VOCs);. inorganic volatile compounds (e.g. mercury, HCN);. permanent gases (i.e. CO2, N2, O2, CH4).ISO 18400-204:2017 does not give guidance on:- risk evaluation and characterization;- selection and design of protective measures;- the verification of protective measures, although the site investigation methodologies described can be used when appropriate;- the sampling of atmospheric or indoor gases;- the measurement of gases from the soil entering into the atmosphere;- monitoring and sampling for radon.
