title: Trace metal and organochlorine residue levels in red mullet (Mullus barbatus) from the eastern Aegean, Turkey.
abstract: The levels of trace metals and organochlorine residue were determined in red mullet (Mullus barbatus) in the framework of a MED-POL II Project for the Aegean Sea during 1994-1998. Samples were analyzed seasonally from July 1994 to January 1998. The concentrations of trace metals found varied with Hg: 16-200 microg kg(-1), Cd: 0.57-4.5 microg kg(-1) and Pb: 40-207 microg kg(-1) wet weight. The order of trace metal concentrations found in Mullus barbatus was Pb > Hg > Cd. Correlation coefficients were calculated between Hg, Cd, and Pb concentrations and fork lengths to be Hg: 0.5852, Cd: -0.081, Pb: 0.5823, respectively. Cadmium levels are lower than the results in fish tissues reported from Mediterranean regions. The results of organochlorine residues measured varied between Aldrin: 0.10 and 0.61 microg kg(-1), t-DDD: 0.86 and 4.5 microg kg(-1) and t-DDE: 10 and 18 microg kg(-1) wet weight. Correlation coefficients for measured organochlorine residues and fork lengths are Aldrin: 0.6422, t-DDD: 0.2237 and t-DDE: 0.5484. The levels of mercury, lead and organochlorine residues are similar to the results in fish from Mediterranean countries.
