Division 7.1.3 Separate determination of PCDD/Fs and dioxin-like PCBs

United Kingdom

Original text. Later amendments are not shown.

Extracts may be split into fractions containing PCDD/Fs and dioxin-like PCBs, allowing a separate indication of PCDD/Fs and dioxin-like PCB TEQ levels (in BEQs). A PCB 126 standard calibration curve shall preferentially be used to evaluate results for the fraction containing dioxin-like PCBs.
