Metal bioaccumulation in Persian sturgeon after sublethal exposure
Tissue metal accumulations (gills, liver, kidney and muscle) in Persian sturgeon (Acipenser persicus) were compared folowing exposure to sublethal levels of waterborne Cd (50, 400 and 1000 μg•L-1) after periods of 1, 2, 4 and 14 days. The obtained results indicate that at the end of 4 and 14 days of exposure, total tissue cadmium concentration followed the pattern: liver > gill > kidney > muscl...
متن کاملMetal Bioaccumulation by Estuarine Food Webs in New England, USA
Evaluating the degree of metal exposure and bioaccumulation in estuarine organisms is important for understanding the fate of metals in estuarine food webs. We investigated the bioaccumulation of Hg, methylmercury (MeHg), Cd, Se, Pb, and As in common intertidal organisms across a watershed urbanization gradient of coastal marsh sites in New England to relate metal exposure and bioaccumulation i...
متن کاملHeavy metal bioaccumulation in commercial Lethrinidae fish species in Mauritius
Concentrations of heavy metals arsenic, cadmium, lead and mercury and trace elements chromium, copper, nickel and zinc were tested in the muscle tissue of four commercial edible lethrinids fish species from different region of Mauritius. Sky emperor (Lethrinus mahsena) was collected from coastal regions as well as offshore regions (banks) for this study. Blackspot emperor (Lethrinus harak) and ...
متن کاملMetal bioaccumulation and metallothionein concentrations in larvae of Crassostrea gigas.
Larval stages of bivalve molluscs are highly sensitive to pollutants. Oysters from a hatchery from Normandy (English Channel) were induced to spawn, and fertilized eggs were exposed to copper or cadmium for 24 h. Metal accumulation (from 0.125 to 5 microg Cu L(-1) and from 25 to 200 microg Cd L(-1)) and MT concentrations were measured in larvae. Compared to controls, larvae accumulated copper a...
متن کاملPotential of Citrobacter freundii for bioaccumulation of heavy metal - copper
The small scale industries located at Mira Road, Mumbai, are engaged in various processes/operations which generate the wastes. The waste generated are collected and disposed of at the dumping ground near the industrial estate. In the present study, the physico-chemical and microbial status of the contaminated sites has been carried out. The heavy metal with special reference to copper was expo...
