Food chains organomercury compounds

In the global cycle of mercury the accumulation in the aquatic food chain plays a predominant role [6]. Inorganic mercury species are methylated in the water chemically or by microorganisms. The organomercury compounds formed enter the food chain. Caused by bioaccumulation in any of the several steps of the aquatic food chain, the highest levels of mercury can be found in the tissues of large predatory fishes such as marine tuna, swordfish, shark, turbot, or halibut and...
