| Resumen: | This Technical Specification specifies the long-term sampling of polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofuranes (PCDFs) and polychlorinated dioxin-like Biphenyls (PCBs) at stationary sources. As a result of their similar chemical behaviour PCBs, as shown in a validation campaigns, can be sampled from stationary sources together with the PCDDs/PCDFs. Therefore it is possible to measure PCBs together with PCDDs/PCDFs. There are three different sampling methods, which use the three different principles described in EN 1948-1 modified for long-term sampling requirements: - filter/condenser method; - dilution method; - cooled probe method. Each sampling method is illustrated in detail. The sampling methods described in this document are designed for a sampling duration of typically four weeks. However, it is also possible to sample during a much shorter duration (e. g. 1 day) or even much longer. Additionally this document specifies a framework of quality control requirements for any long-term sampling method to be applied. With the methods described experiences were gained so far for a concentration range from typically 0,003 ng I-TEQ/m3 up to 4,0 ng I-TEQ/m3 and 0,003 ng WHO-TEQ/m3 up to 4,0 ng WHO-TEQ/m3 respectively at different stationary sources (e. g. waste incinerators, sinter plants, cement kilns). The user of the filter/condenser method and the cooled probe method shall take into account patent rights. |
