DOI: 10.1002/elps.202200004
Abstract: A fast and environment‐friendly analytical method was implemented to determine multiclass pesticides in river sediments. Twenty‐three pesticides—organochlorine pesticides, organophosphorus pesticides, and triazines—were extracted via matrix solid‐phase dispersion (MSPD) and analyzed by gas chromatography–tandem mass spectrometry… read more here.

DOI: 10.1007/s11368-016-1590-3
Abstract: Purpose Polybrominated diphenyl ethers (PBDEs) are flame retardants and regarded as emerging contaminants and persistent organic pollutants (POPs). Due to high lipophilicity and low biodegradability, they tend to accumulate in sediments. Decabrominated diphenyl ether (BDE-209)… read more here.
