Indoor air - Determination of total (gas and particle-phase) polychlorinated dioxin-like biphenyls (PCBs) and polychlorinated dibenzo-p-dioxins/dibenzofurans (PCDDs/PCDFs). Collection on sorbent-backed filters1 Scope This part of ISO 16000 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 (see Table C. 1). 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
