Analyses of organochlorine pesticides residues in eels (Anguilla anguilla) from Lake Garda using Gas chromatography coupled with Tandem Mass Spectrometry (GC-MS/MS).
Lake Garda is located in Insubria region, that is known for being the most populated and industrialized area of Italy (Camusso et al., 2001). Therefore, the Lake water, and also the fish species present, could be affected by environmental contamination. European eel (Anguilla anguilla) are consider...
