Abstract EN
The organic contaminants, including polycyclic aromatic hydrocarbons (PAHs), organochlorine pesticides (OCPs), polybrominated diphenyl ethers (PBDEs), and polychlorinated biphenyls (PCBs), are of priority concern because of their persistence, toxicity, and long-distance transportation in global environment.
Their residues in a daily consumed fish (grass carp) pose potential threat to human health and aquatic ecosystems.
The present study optimized an analytical protocol of microwave-assisted extraction (MAE), lip-removal by gel permeation chromatography (GPC), cleanup by solid phase cartridge (SC) or adsorption chromatography column (CC), and gas chromatography-mass spectrometry (GC/MS).
Besides traditional statistical parameters, some indicators were calculated to judge the performances of extraction by various methods.
The optimization experiment showed that n-hexane/acetone was the best MEA extraction solvent; an optimal fraction time of 10–39 min could simultaneously elute all the target chemicals in a single GPC run.
Both CC and SC showed good recoveries.
However, CC performed better than SC (p<0.05) for OCPs, and SC performed better than CC for PBDEs (p<0.05).
We also emphasized the limitations and advantages of SC and CC and finally proposed SC as the promising cleanup method because of its low-cost materials, time-saving steps, being free of manual filling, and operation by automated SPE system.
