Heavy metals in Southern Baltic fish: present situation and future trends
Herring (Clupea harengus) and cod (Gadus morhua) from three Southern Baltic areas were studied. Mercury content was determined with CV AAS and assays of the remaining metals were carried out with flame AAS. A correlation between the fishing area and contents of Hg, Cd, Cu, and Zn in fish tissues was...
