Significant Progress on the Development of Covalent Organic Frameworks-Based Solid-Phase Microextraction Probe
Rapid, sensitive, and accurate analysis of trace environmental pollutants is urgently required in the field of environmental analytical chemistry. Per- and polyfluoroalkyl substances (PFASs) are a series of persistent organic pollutants (POPs) widespread in environment and organism, and they have been concerned widely by both health authorities and public due to their hepatotoxicity, reproductive toxicity, and potential carcinogenicity. Perfluorooctanesulfonic acid (PFOS) and perfluorooctanoic acid (PFOA) are the two most widely used PFASs that have been designated as target chemicals for regulation by the Stockholm Convention on POPs. It is necessary to monitor the contents and compositions of PFASs in environmental and biological media for understanding their environmental behaviors and toxic effects.
