Feeding interactions affected by ecosystem structures determine the degree of MMHg biomagnification. We estimate a total of 6.1 metric tons of MMHg potentially digested by the global population per year through marine fish consumption.
Biomagnification is the buildup of concentration of a substance (x) in a food chain. For example the DDT concentration in parts per million increases with trophic level. Concentrations build up in organism's fat and tissue. Predators accumulate higher levels than prey. See more Biomagnification, also known as bioamplification or biological magnification, is the increase in concentration of a substance, e.g a pesticide, in the tissues of organisms at successively higher levels in a See more Although sometimes used interchangeably with "bioaccumulation", an important distinction is drawn between the two, and with bioconcentration. • Bioaccumulation … See more Two common groups that are known to biomagnify are chlorinated hydrocarbons, also known as organochlorines, and inorganic compounds like methylmercury or heavy metals. … See more In a review, a large number of studies, Suedel et al. concluded that although biomagnification is probably more limited in occurrence than previously thought, there is good … See more • Mercury in fish • Methylmercury • Dichlorodiphenyldichloroethylene See more • Fisk AT, Hoekstra PF, Borga K,and DCG Muir, 2003.
