Abstract Analyses of pollutants, organochlorine residues and heavy metals (Cu, Zn, Mn, Cd, Pb, Hg) were carried out in deep-sea organisms, Asteridea, Holoturioidea, fishes.Heavy metals conlent was determined in sediments. Organochlorine residues were detected in all deep-sea organisms.However, the concentrations observed are similar to those for marine organisms from coastal areas.For heavy metals, high concentrations of mercury, up to 7.5 ppm/dry weight and 6.5 ppm are observed in echinoderms and sediment respectively.High concentrations of lead, up to 167 ppm, occur in the gills of fishes.For other metals, the values observed are roughly similar to those from the literature.
