![]() Hg and P were found to increase their concentrations from zoobenthos to wild fish aggregating around fish cages feeding on macrofauna. The ecological and morphological characteristics of the benthic invertebrates can affect the bioaccumulation of metals and elements in macrobenthos. Tolerant species were found to accumulate higher concentrations of most metals and elements, except for Cd, than equilibrium species. Elemental concentrations of benthic organisms increasedwith increasing sediment metal content, except Cd, andwith % silt, refractory organicmatter and chlorophyll-a of sediment due to the influence of sediment geochemistry on metal bioavailability. ![]() Macroinvertebrates accumulated lower concentrations of most metals and elements than their respective sediment, except As, P, Na, Zn and Cd. ![]() 0.3 0.4 0.5 0.6 0.7 0.8 0.9 ORIGIN Black Magic Design The Complete Smith Chart. Biological and geochemical characteristics play an important role in metal accumulation in benthic invertebrates, and consequently in metal transfer to higher trophic levels. Veja grtis o arquivo Carta de Smith enviado para a disciplina de Ondas. Concentrations of metals and other elements were measured in macrofaunal taxa and in fish tissues (muscle, liver, gills, bone, gonad, stomach, intestine, and stomach content). Benthic macroinvertebrates and wild fish aggregating in the vicinity of four Mediterranean fish farms were sampled.
