PCB determination in sediment
Polychlorinated biphenyls (PCBs) are a class of organic compounds based on biphenyl substituted with 1-10 chlorine atoms. They are toxic, persistent and bioaccumulate in terrestrial and aquatic biosystems and are ubiquitous in the environment. This Application Note describes the extraction and determination of PCBs in a dried sediment SETOC sample according to EPA 3541. The sample was extracted with the UniversalExtractor E-800 in the Soxhlet warm mode.
