“…This cadmium distribution (concentration decreases in the sequence kidney > liver > muscle) corresponds to the metal distributions detected in rainbow trout exposed to polluted water with a lower cadmium concentration of 5.5 g liter −1 (Brown et al, 1994), in eels exposed to 130 g liter −1 cadmium chloride for 60 days (Gill et al, 1992), and in carp exposed to 1.4 g liter −1 (Kraal et al, 1995). Report on the pattern of cadmium uptake in liver and kidney of fish can be divided into two groups according to the presence or absence of a plateau in the cadmium accumulation kinetic curves.…”

“…The decrease in WBC counts after 96 h may be attributed to immunological suppression of the cells by Cd. Brown et al [2] reported that rainbow trout exposed to Cd (4 mg L À1 after 14 days) showed a total WBC increase compared to control, while after 96 h, there was a decrease in WBC counts. Statistical analysis revealed that only fish exposed to 48 h of 0.054 mg L À1 of Cd showed significant differences (p > 0.05) in WBC counts when compared with the control.…”

“…In humans, Cd tends to accumulate in the liver and kidney, produces irritation of respiratory and gastrointestinal tract, and, if inhaled, produces respiratory diseases [8].The importance of experimental exposure of fish to heavy metal concentrations for predicting potential damage to aquatic ecology has been advocated [2,4,10]. Information obtained from various toxicity tests may be used in the management of water pollution to estimate the environmental adverse effects of heavy metals and for regulation of the amounts discharged into waterways [3].…”

Fish of species Parachanna obscura are exposed to four concentrations of cadmium (Cd) (0.02, 0.06, 0.18, or 0.54 mg L À1 ). Acute toxicity test results after 96 h showed marked hematological, histological, and behavioral changes. Quantitative blood analysis revealed that white blood cell (WBC), packed cell volume (PCV), and platelets counts were linearly correlated with increasing Cd concentrations; however, blood haemoglobin (Hb) showed an inverse relationship, with higher Hb levels at lower Cd concentrations. Histological changes of the liver showed hepatic separation, bloody appearance, and deposition of a brownish-yellow substance, which increased with rising concentrations of metal. Behavioral changes observed included reduced activity, avoidance response, and deposition of a slimy-whitish film on the body of the fish, which increased with concentration and exposure time.

“…The regression of the ELS chronic values, including an ELS test at a water hardness of 44 mg/L [6] and a life-cycle test at a water hardness of 250 mg/L [7], provides a good fit, with a correlation coefficient of 0. Chronic end points of the ELS tests were consistently greater than those in the tests initiated with fry and even exceeded 96-h LC50s (Table 2).…”

Abstract-Toxicity of cadmium to early life stages of brown trout (Salmo trutta) was determined at multiple water hardnesses. Increasing water hardness decreased cadmium toxicity. Postswimup fry were much more sensitive than embryos and larvae. Chronic values from early life stage tests initiated with eyed embryos were 3.52, 6.36, and 13.6 g Cd/L at water hardnesses of 30.6, 71.3, and 149 mg/L, respectively. In tests initiated with 30-d postswimup fry, chronic values were 1.02, 1.83, and 6.54 g Cd/L at water hardnesses of 29.2, 67.6, and 151 mg/L, respectively. Higher chronic values from the early life stage tests compared to tests initiated with swimup fry likely are caused by acclimation during cadmium-tolerant embryo and larval stages. Growth was not affected by cadmium in the early life stage tests but was negatively affected in tests initiated with fry at water hardnesses of 29.2 and 67.6 mg/L. Concentrations of cadmium that reduced growth were higher than those that increased mortality. Median lethal concentrations for swimup fry after 96 h were 1.23, 3.90, and 10.1 g Cd/L at water hardnesses of 29.2, 67.6, and 151 mg/L, respectively. Test results enable prediction of acute mortality of brown trout swimup fry based on cadmium concentration and water hardness.
