Dietary Sources Dominate Metal Uptake in Marine Fish
نویسندگان
چکیده
The bioaccumulation of 10 metals in five fish species was experimentally evaluated following exposure to dietary or aqueous metal at environmentally realistic metal concentrations. A biokinetic model showed that, with few exceptions, >90% of a fish’s metal body burden was obtained from diet. Regulatory bodies need to consider these findings in setting appropriate water quality criteria. Metal uptake from the aqueous phase was influenced by dissolved organic carbon and salinity, but no consistent patterns were evident for all metals.

Assimilation and bioconcentration of Ag and Cd by the marine black bream after waterborne and dietary metal exposure.
We determined the aqueous uptake and dietary assimilation of Cd and Ag by the marine black bream Acanthopagrus schlegeli following one to four weeks' exposure (or conditioning) to waterborne or dietary Cd or Ag at different concentrations. The concentrations of metals and metallothioneins (MT) in different tissues also were determined. The viscera contained the highest Ag, Cd, and MT concentrat...

We investigated how the subcellular metal distribution in prey affects metal dietary assimilation in a marine fish, the grunt Terapon jarbua. The assimilation efficiency (AE) of metals (Cd, Se, and Zn) in the grunt varied by prey, which included copepods, barnacles, clams, mussels, and fish viscera. The AEs were 3–9% for Cd, 13–36% for Se, and 2–52% for Zn. The AEs of Se and Zn were significant...

The aim of this study was to examine the changes in muscle proteome of the rainbow trout fed dietary β-glucan. The experimental diets contained 0 (control), 0.1% and 0.2% β-1,3/1,6 yeast glucan. First, feeding larvae were fed to apparent satiation nine times per day with their respective diets over two months. The percentage of body weight gain and feed efficiency of fish fed 0.2% diet was sign...

Heavy metal metals are non-biodegradable, have a remarkable ability to transfer through food chains and are potentially toxic for organisms.They are introduced tomarine environment via different anthropogenic sources. In this study, the ability of titanium dioxide nano-particle in transfer of Cr, Cu, Pb and Se metal through an aquatic food chain involving Ceratium tripos as the phytoplankton Da...
متن کاملAssessment of Accumulation and Potential Health Risk of Cr, Mn, Fe, Cu, and Zn in Fish from North-Eastern Mediterranean Sea
Heavy metal accumulation in aquatic organisms has been an important issue due to environmental pollution resulting from anthropogenic activities. In this study, Cr, Mn, Fe, Cu, and Zn in the selected fish species (Mullus barbatus, Solea solea, and Siganus rivulatus) from three consecutive bays (İskenderun, Mersin, and Antalya from North-Eastern Mediterranean Sea) were considered to provide some...
