Ecological study of gas fields in the northern Adriatic. 9. Heavy metals and macroconstituents in sea water

Abstract

       In March 1986 the content of heavy metals and macroconstituents in sea water was analyzed in the IVANA field, as well as the content of heavy metals in fish and shellfish stretching from the IVANA field to cove Štinjan near Pula. The content of heavy metals in sea water is slightly increased whereas the concentration of heavy metals in organisms is within the limits of an unpol­luted area. The analysis of macroconstituents showed that the sea water can be characterized as clean sea.
