Determination of OCPs and PCBs in Sediments

Persistent organic pollutants (POPs), such as organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs), pose significant environmental risks due to their toxicity and tendency to bioaccumulate. Monitoring these compounds at ultra-trace levels in sediment is challenging because of the high complexity of the matrix. By combining solid-phase extraction (SPE) with the enhanced separation power of comprehensive two-dimensional gas chromatography (GCxGC) and high-sensitivity time-of-flight mass spectrometry (TOFMS), the Pegasus BTX 4D provides the resolution and detection limits necessary for rigorous environmental assessment and regulatory compliance.
