Cu accumulation and depuration in various tissues of the crayfish Astacus leptodactylus was investigated. Adult specimens were exposed to 0.5, 2.5 and 5.0 mg Cu/L under static conditions for three weeks. At the end of the 3rd week the specimens were divided into three groups and left in dechlorinated water for either 1, 2 or 3 weeks for depuration. After 7, 14 and 21 days, four crayfish from ea...

background: this study aims to investigate the patterns of bioaccumulation and depuration of copper in the selected kidney and liver of capoeta fusca. methods: the fish were collected between september and november 2010 from a qanat in birjand. they were exposed to two types treatments with copper (0.25 and 0.75 mg/l) for a period of 41 days. the fish under study were exposed to the above-menti...

Vibrio vulnificus is an estuarine bacterium which can cause opportunistic infections in humans consuming raw Gulf Coast oysters, Crassostrea virginica. Although V. vulnificus is known as a ubiquitous organism in the Gulf of Mexico, its ecological relationship with C. virginica has not been adequately defined. The objective of the present study was to test the hypothesis that V. vulnificus is a ...

This study aimed to examine the usefulness of locally found gastropod snail, Nerita lineata as suitable biomonitor for metal pollution. The accumulation and elimination of chromium (Cr) and lead (Pb) was examined by exposing N. Lineata to different concentrations of Pb (1-4ppm) and Cr (12-15 ppm) under controlled laboratory conditions. The experiments were allowed for four days of accumulation ...

The present study investigated the accumulation and depuration of two heavy metals Cd and Pb in the freshwater clam  (Corbicula fluminea) under laboratory conditions. Treated clams were exposed to single and combined treatments of Cd and Pb at the concentration of 5 mg L-1 and 10.5 mg L-1 for 10 days, respectively. The animals were then placed in metal free water for the following 5 days for de...

Eye-pigmented eggs of landlocked salmon were exposed to waterborne [14C]-labeled bisphenol A at four temperatures (2, 6, 8, and 12 degrees C). Both in accumulation and depuration experiments, the eggs were exposed to a bisphenol A concentration of 1 microg/L for 196 h. In the depuration experiment, the exposed eggs were placed into clean water for 96 h. At each sampling time, the eggs were diss...

We determined the respiratory uptake and depuration kinetics of perfluorooctanesulfonate (PFOS) in Perinereis wilsoni, a polychaete sandworm used as a model species to investigate the fate of chemical pollutants in coastal environments. The sandworms were kept in gravel-packed containers, and the water levels were varied cyclically to mimic the tides. We used seawater kept at 17.1°C. A 7-day ex...

A local strain of the dinoflagellate Alexandrium tamarense (ATCI01), which predominantly produces C2 toxin, was fed to the clams (Ruditapes philippinarum) under laboratory conditions. Concentrations of paralytic shellfish toxins (PSTs) in the dosed clams were determined by High Performance Liquid Chromatographic (HPLC) analyses, and the clams were homogenized and then fed to the gastropods (Nas...

Effect of depuration on content geosmin in pikeperch (Sander lucioperca) produced a commercial RAS farm was examined during 15-day period. Concentrations the fish were related to water. For depuration, half water volume 230 m3 production tank replaced daily with geosmin-free After 8 days and absence feeding, reduced from 710 ± 245 ng/kg 165 50 (mean SD, p < .01). Additional for 7 only 135 24 ng...
