Indoor air — Part 13: Determination of total (gas and particle-phase) polychlorinated dioxin-like biphenyls (PCBs) and polychlorinated dibenzo-p-dioxins/dibenzofurans (PCDDs/PCDFs) — Collection on sorbent-backed filters
室内空气第13部分:多氯联苯(PCBs)和多氯联苯对二恶英/二苯并呋喃(PCDDs/PCDFs)总含量(气相和颗粒相)的测定——吸附剂反滤器的收集

ISO 16000-13:2008规定了室内空气中二恶英类多氯联苯(PCBs)、多氯联苯类二恶英(PCDDs)和多氯联苯类二恶英(PCDFs)的采样和采样介质的制备。该方法采用了一种采样程序,通过吸附剂捕集器支撑的细颗粒过滤器从空气中收集多氯联苯和多氯二苯并呋喃/多氯二苯并二恶英。该方法不能用于单独测定气态多氯联苯和多氯二苯并呋喃/多氯二苯并二恶英以及与颗粒有关的物质,因为一些化合物会从过滤器中挥发,并被吸附剂捕集器收集。ISO 16000-13:2008未涉及ISO 16000中包含的多氯联苯、多氯二苯并对二恶英和多氯二苯并呋喃的分析方法-

ISO 16000-13:2008 specifies sampling and preparation of sampling media for dioxin-like polychlorinated biphenyls (PCBs), polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) in indoor air. The method incorporates a sampling procedure that collects PCBs and PCDFs/PCDDs from air on a fine-particle filter backed up by a sorbent trap. The method cannot be used to separately determine gaseous PCBs and PCDFs/PCDDs and those that are particle-associated because some of the compounds will volatilize from the filter and be collected by the sorbent trap. ISO 16000-13:2008 does not address analytical methods for PCBs, PCDDs and PCDFs, which are included in ISO 16000-14.
