Exposure of Carcinus maenas to waterborne fluoranthene: Accumulation and multibiomarker responses

► Concentration-dependent accumulation of waterborne fluoranthene (FLU) in Carcinus maenas ► Strong relationship between FLU residues (GC-MS) and FLU-type compounds (fixed wavelength fluorescence) ► Increased anti-oxidant defences and neuromuscular toxicity followed FLU bioaccumulation ► FLU-type compounds were the most sensitive measure of FLU exposure and availability
