Describes the long-term sampling of PCDDs, PCDFs and PCBs.

This Technical Specification specifies the long-term sampling of PCDDs, PCDFs and PCBs. There are three different sampling methods, which use the three different principles described in EN1948‑1 modified for long-term sampling requirements: filter/condenser method; dilution method; cooled probe method. Each sampling method is illustrated in detail in AnnexD. The sampling methods described in this document are designed for a sampling duration of typically four weeks. Additionally this document specifies a framework of quality control requirements for any long-term sampling method to be applied (see AnnexC and AnnexF). With the methods described experiences were gained for a concentration range from typically 0,003ng I-TEQ/m 3 up to 4,0ng I-TEQ/m 3 and 0,003ng WHO-TEQ/m 3 up to 4,0ng WHO-TEQ/m 3 respectively at different stationary sources (e.g. waste incinerators, sinter plants, cement kilns). For the complete measurement method the use of EN1948‑2 and EN1948‑3 describing extraction and cleanup and identification and quantification, respectively, is necessary in order to determine PCDDs/PCDFs. Also EN1948‑4 is necessary for the analyses of dioxin-like PCBs.
