Carbonized loofah sponge-based solid-phase extraction of benzo[a]pyrene from fish followed by liquid chromatography-ultraviolet detection

CLS was used for the first time as an SPE adsorbent for the extraction of BaP in fish. An analytical method for BaP in fish was developed and it provides an alternative way for the efficient analysis of BaP in aquatic food and can be used to ensure food safety.
