The seasonal input and distribution of organic contaminants in the Mar Menor lagoon have been recently characterized in seawater and sediments, showing the significant impact of flash flood events. Mar Menor is a hypersaline (42-47 psu) coastal lagoon located in the Cartagena Field area at the South East of Spain subjected mainly to intensive agriculture, seasonal tourism and recreational activities. The bioaccumulation of polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs) and organochlorinated pesticides (OCPs) has been also determined in bivalves, but no information was available about their accumulation in fishes. In this study the concentrations of PAHs, PCBs and OCPs in golden grey mullet (Liza aurata) and red mullet (Mullus barbatus) muscle were determined. Their spatial distribution throughout the Mar Menor lagoon was characterized considering 9 sampling areas and two different sampling periods, spring and autumn in 2010 for golden grey mullet and only one ...
