In regions where commercial fisheries play a major role in the economy, large scale poisoning of the aquaculture can have a devastating effect. It is important for forensic investigations that the toxic chemicals can be identified and quantitated accurately. Haipeng Jiang and Jing Zou at the Wuhan Institute of Technology have developed an LC-MS/MS method for the simultaneous determination of three commonly used fishpond poisons: pentachlorophenol, niclosamide and fenpropathrin. These compounds are particularly challenging to detect by conventional GC-MS methods. The authors tested their procedure using a real life case study of fish poisoning in Hubei Province, China, where an unknown toxin diminished the production of farmed pearls in the area in 2010.
