“…The transfer ratio (concentration in feathers vs concentration in the diet) was 22. The maximum value measured (17% incorporation) was 0.85 mg mercury/kg feathers, compared to 0.09 mg for the control (soybean) diet (March et al, 1974).…”

“…In chickens, organic mercury is distributed in tissues, crosses the oviduct of the laying hen to the egg and is deposited in the feathers (March et al, 1974 and1983). Female mallards (Anas platyrhynchos) fed diets containing high levels of methylmercury (5 to 20 mg/kg) laid eggs containing 7 to 55 mg total mercury/kg of which 95 to 100% was methylmercury, which is preferentially deposited in the egg albumen rather than the yolk (Heinz and Hoffman, 2004).…”

“…Lassiter and Morton (1968) fed low dietary Mn concentrations to sheep and found reduced concentrations of Mn in the heart and liver of the sheep. Many types of fish meal contain high concentrations of Hg and when fed to animals, Hg accumulates in the animals' tissues (March et al, 1974b). Underwood (1977) reported that bones are tissues of intermediate Cu concentration and, like liver and kidney, are particularly responsive to changes in Cu intake.…”

The genetic and nongenetic factors affecting the elemental composition of animal and human tissues are presented. Genetic factors include: (1) some well-known inherited diseases that affect copper, zinc, iron, magnesium, manganese and selenium metabolism; (2) animal species differences and (3) breed differences within animal species. The nongenetic factors include regional variation, dietary concentration of elements, interactions between elements, dietary concentration of other nutrients, chemical form of elements, age, sex, hormones, pregnancy, disease, temperature and altitude.

The Gulf of Urabá, currently considered a national strategic ecoregion, could be threatened by the presence of heavy metals such as mercury (Hg), lead (Pb), and cadmium (Cd), which directly affect the aquatic ecosystem. In Colombia, investigations on marine species pollution are scarce; however, their products are consumed. The aim of this study was to quantify the contents of Hg, Pb, and Cd in muscle and in waste material (head-gills, viscera, fins-tail), in one of one of the most commercialized resources, the crevalle jack (Caranx hippos), and to determine their presence in some of the body portions that are used in the production of sub-products. The concentrations of Hg, Pb, and Cd were compared between the waste material and muscle of the crevalle jack fish that were caught from each of the following sites the community usually uses to catch them: Bahía Candelaria, Bahía Marirrío, Bocas del Roto, and Bocas del Atrato. They were captured every 1 year in each climatic period. All body portions exceeded the maximum allowed limits for Pb (0.667-23.378 mg kg); the highest Hg concentrations were found in muscle (0.515-7.019 mg kg) and viscera (0.172-1.883 mg kg), and for Cd, the parts with the highest levels were the fins-tail (0.040-0.15 mg kg) and viscera (0.040-0.174 mg kg). Considering the obtained results, it is not recommended to use the waste material for the production of fish meal or fish silage due to the adverse effects it could cause on both animals and humans.
