Summary. 1  Fish that contain high levels of mercury include shark, orange roughy, swordfish and ling. 2  Mercury is a naturally occurring element that is found in air, water and food. 3  The unborn baby is most sensitive to the effects of mercury, particularly during the third and fourth months of gestation.
This is biomagnification, and it means that higher-level predators-fish, birds, and marine mammals-build up greater and more dangerous amounts of toxic materials than animals lower on the food chain.In this activity you will explore the biomaginification of toxic chemical, mercury, through a simple marine food chain.ercury is stored within an animal's tissues. Clams have fairly low concentrations of the substance. Clam-eating fish accumulate all the mercury from all the clams they consume, so they have much higher concentrations. Birds, in turn, swallow all the mercury in all the fish and/or clams they eat.
