“…According to various authors, cadmium concentration in freshwater fish tissues (intestine, muscles, kidney, gill, skin, spleen, brain, liver) usually does not exceed 2 μg/g (Kraal et al 1995; Hollis et al 1999; Panchanathan and Vattapparumbil 2006; Wu et al 2007; Singh et al 2008; Tao et al 2008; Vinodhini and Narayanan 2008; Dang et al 2009; Isani et al 2009). According to Calta and Canpolat (2006), natural level of copper in the tissues of cyprinid fishes ( C. carpio , Acanthobrama marmit , Chondrostoma regium ) were in muscles below 5 μg/g, in gill 5–10 μg/g, in skin near 10 μg/g, in gonads 5–20 μg/g, and in liver 15–30 μg/g.…”

The aim of the present study was to evaluate bioaccumulation of metals in various tissues of the freshwater fish Cyprinus carpio L. exposed to cadmium and copper (a xenobiotic and a microelement). The fish were subjected to short-term (3 h, Cd-S and Cu-S) or long-term (4 weeks, Cd-L and Cu-L) exposures to 100 % 96hLC50 or 10 % 96hLC50, respectively. Blood, gill, liver, head and trunk kidney were isolated weekly from 5 fish of each group for 4 weeks (post-short-term exposure and during long-term exposure). Atomic absorption spectrophotometry technique was applied to measure concentrations of metals (Cd and Cu) in fish tissues. Initial concentrations of copper in fish tissues were higher than levels of cadmium. Cadmium and copper levels increased in all tissues of metal-exposed fish. After short-term exposures (at higher concentration) and during long-term exposures (at lower concentration), similar changes in metal concentrations were observed. The values of accumulation factor (ratio of final to initial metal concentration) were higher for cadmium as compared to copper. Comparison of metal levels and accumulation factors in various tissues revealed that cadmium and copper showed very high affinity to head kidney of common carp (higher than to other tissues), but accumulation factors for cadmium in trunk, head kidney and liver were much higher than for copper. The concentrations of copper in organs of Cu-exposed fish increased only slightly and quickly returned to the control level, which shows that fish organism easily buffered metal level. On the other hand, concentrations of cadmium considerably increased and remained elevated for a long time which suggests that activation of mechanisms of sequestration and elimination of cadmium required more time.

“…In a report, it is shown that gills are the storehouse of Cadmium in an experiment conducted by (Allen, 1995; Giguère et al, 2004; Ramesh & Nagaranjan, 2007; Tao, Liu, Dawson, Long, & Xu, 2000). Wong (2000) in its experimental work shown morphological and biochemical changes in the gills of Tilapia ( Oreochromis mossambicus ) and also reported that chloride cells are the first site of cadmium toxicity, which results in hypocalcemia, while intestines, and gonads of fish are the organs of fish which can be easily affected by cadmium (Kumari & Ramkumar, 1997).…”

The present study aimed to evaluate and compare the toxicity level of dietary and waterborne Cadmium (Cd) source on the Goldfish Carassius auratus (C. auratus) using various biochemical and microscopic shreds of evidence. C. auratus were divided into two groups based on Cadmium supplementation methods subjected to the same concentrations in the diet and water; moreover, control (Ctrl) group was set up for comparison. Dietary supplemented group (DSG) group and (Aqueous supplemented groups) ASG were supplied with 0.5% of the Cadmium. Successful completion of the study resulted in the lucrative outcomes, and we noticed significantly high concentrations of Cadmium in the gills of the ASG fish while considerably low levels in the gills of DSG. Histopathological evidence showed clear and distinct changes in the liver cells, dilated sinusoids and unusual occurrence of Kupffer cells were noticed in the AS group fish. At the same time, there were also noticeable changes in the DS group compared to CTRL. Visible changes can be seen on the outer morphology of gills, lamella of ASG and DSG both were shrunk and broken, similar changes were noticed in the muscles myoepithelium. The stress parameters were differentially expressed in both the groups; waterborne Cadmium caused a pronounced release of AST, ALT, cortisol, and glucose concentrations. Comparative mortality showed the highest death rate in the ASG fish compared to DSG fish. The present study depicts the highest toxicity of Cadmium in the soluble Addendum form moreover, administered route and time length are crucial factors.

“…Owing to direct contact with ambient water, gills are proposed to be the first and most important targets of fish exposed to waterborne metals (Playle 1998;Wong and Wong 2000;Tao et al 2000). Several studies also indicated that the major route of uptake for metals that concentrate in fish is across the gill epithelium (Pelgrom et al 1997;Bury et al 1999).…”

Farming of tilapia Oreochromis mossambicus is an important aquacultural activity in Taiwan. Due to the elevated arsenic (As) concentration in pond water, it is important to assess the bioavailability and toxicity of As to tilapia for protection of aquatic life and human health. In the present study, we developed a biotic ligand model (BLM)-based toxicodynamic approach to dynamically predict both acute and chronic effective concentrations of As to tilapia in two tilapia farms located at Pudai and Chiangchun counties in southwestern Taiwan. Parameters revealed in the mechanistic model were obtained by fitting this model to the toxicokinetic and toxicodynamic data from our previous laboratory experiments. Based on our extended BLM concepts, the site-specific water effect ratios and ambient water quality criteria can be determined with known water chemistry. The proposed methodology was capable of bridging the gap between laboratory toxicity bioassays and field investigations. With respect to risk assessments, our research may also provide an useful means of generating and adjusting the site-specific ambient water quality criteria.
