mercury bioaccumulation in some commercially valuable marine organisms from mosa bay, persian gulf
this study was undertaken to determine the concentration of mercury in edible muscle of five commercially valuable marine organisms from mosa bay, persian gulf, iran. the total mercury concentrations were determined by cold vapour atomic absorption spectrophotometry and expressed in μg/g dry weight. certified reference materials were used for each batch of analysis. mercury concentration was 0....
متن کاملFactors influencing cadmium accumulation and its toxicity to marine organisms
The toxicity of dissolved cadmium to a variety of marine animals has been found to be related to salinity, with decreased toxicity observed at higher salinities. Recent data from our laboratory have demonstrated that the toxicity of cadmium to estuarine shrimp and larval fish is a function of free cadmium ion concentration, which in turn is controlled by the chloride concentration of the water....
متن کاملbioaccumulation in marine birds
The aim of this work was the determination of Po, U, U, Pu and Pu concentration in marine birds which permanently or temporally live in the southern Baltic Sea coast. We chose 11 species of seabirds: three species permanently residing at southern Baltic Sea, four species of wintering birds and three species of migrating birds. The results show that analyzed radionuclides are non-uniformly distr...
متن کاملDifferential bioaccumulation of (134)Cs in tropical marine organisms and the relative importance of exposure pathways.
Bioaccumulation of (134)Cs was determined in 5 tropical marine species: three bivalves (the oysters Isognomon isognomum and Malleus regula, and the clam Gafrarium pectinatum), one decapod (shrimp Penaeus stylirostris) and one alga (Lobophora variegata). Marine organisms were exposed to the radionuclides via different pathways: seawater (all of them), food (shrimp and bivalves) and sediment (biv...
متن کاملMetal bioaccumulation in representative organisms from different trophic levels of the Caspian Sea
The bioaccumulations of metals Cu, Cd, Ni, Cr, Co, Mn, Zn and Fe were measured in bivalves, Cerastoderma glucaum, and four species of fishes including Alburnus chalcoides, Liza aurata, Rutilus frisii and Sander lucioperca from various trophic levels of the Caspian food web. The concentrations of Cd, Cr, Co and Ni in most samples of fish were below the detection limits; while the concentrations ...
