Persistent organic pollutants (POPs) include diverse classes of chemicals including polychlorinated dibenzo‐p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), polychlorinated biphenyls (PCBs), polybrominated diethyl ethers (PBDEs), polyaromatic hydrocarbons (PAHs), chlorinated parafins (CPs), and others. These compounds are produced intentionally or unintentionally as waste during industrial and commercial applications and manufacturing processes. Several of these compounds are listed under the United Nations (UN) Stockholm Convention for elimination or reduced usage globally.
Due to their toxicity and persistence, several countries have taken steps to limit POPs pollution. Still, POPs are widely used, especially in developing economies, and legacy sites with dangerous levels of POPs contamination can be found in many regions of the world. Regulated methods for POPs testing in soil, sediment, and solids include US EPA Methods 1613B and 8290 for PCDD/F determination, and US EPA Method 610 and Chinese HJ 805-2016 Method for PAHs analyses.
Agilent provides a comprehensive suite of products and unique capabilities to assist labs with the development and deployment of robust methods to identify, quantify and profile POPs. For a complete solution, pair your instruments with our wide selection of columns and supplies designed for rapid analysis, and reproducibly high performance for challenging samples.
Determination of highly toxic POPs, dioxins, and furans in environmental samples is complex and requires highly sensitive and selective instrumentation.
Toxic, and ubiquitous across the world, commonly monitored PAHs include multiple sets of structural isomers that are difficult to analyze.
Widespread and persistent in the environment, analysis of low-level PCBs in matrices requires efficient sample preparation and sensitive instrumentation.
Emerging environmental contaminants, PBDEs and NBFRs produce complex chromatographic profiles that benefit from the enhanced selectivity of GQ/TQ methods.
