“…Results show that the median lethal concentration (LC50) of nickel to Catla catla for 24, 48, 72 and 96 h of exposure are 10.113 mg/l, 9.065 mg/l, 7.386 mg/l and 5.77 mg/l, respectively and to Clarias batrachus for 24, 48, 72 and 96 h of exposure are 11.662 mg/l, 10.572 mg/l, 8.944 mg/l and 7.595mg/l, respectively (Table 1). Abdulla and Javad (2006) reported the 96h LC50 of Nickel for 30 days Catla catla fingerling was 11.83 mg/l. Observations on the upper and lower confidence limits revealed a decreasing trend from 24h to 96h.…”

Industrial effluent is the major sources of heavy metal pollution and it is released into fresh waterbodies. Catla catla and Clarias batrachus were exposed to Nickel and Chromium for 24, 48, 72 and 96 hrs. The median lethal concentration (LC50) of nickel to Catla catla and Clarias batrachus for 96 h of exposure were 5.77 mg/l and 7.595mg/l, respectively. The median lethal concentration (LC50) of chromium to Catla catla and Clarias batrachus for 96 h of exposure were 16.468 mg/l and 34.476 mg/l, respectively. The result also revealed that mortality rate depends upon concentrations of heavy metals and duration of exposure. The acute toxicity levels were derived from LC50 concentrations of the heavy metals. Both the heavy metals produced lethality at smaller doses. Physiological responses like rapid opercular movement and frequent gulping of air was observed during the initial stages of exposure after which it became occasional. All these observations can be considered to monitor the quality of the aquatic ecosystem and the severity of pollution.

“…Environmental conditions like oxygen concentration, pH, hardness, temperature, and presence of other metals might influence metal toxicity to the fish. Hypoxic conditions, temperature, increase and acidifications usually render the fish more susceptible to intoxication, while increases in mineral contents (hardness and salinity) decrease metal toxicity (Abdullah and Javed, 2006; Rathore and Khangarot, 2003). On the other side, as the pH of the near environment can influence mucus secretion or formation, reduction in the pH might alter the mucus, causing reduced metal uptake (Karthikeyan et al, 2007).…”

“…Acute toxic influence happens in two levels, immediate and delayed. First symptoms of overexposure to heavy metals are perplexity and lack of breath; the postponing effects (10–36 h) are bluish discoloration of the skin and finally death (Abdullah and Javed, 2006). Bioassays allow study, under controlled conditions, of some parameters such as mortality, behavior alterations, or damage in tissues or cells and can help predict some effects of mercury (Hg) in natural aquatic ecosystems (Olivera ribeiro et al, 1996).…”

Acute toxicity bioassay of mercury and silver on Capoeta fusca (black fish)

Since toxicity is based on the effect that a toxicant produces at a target site within an organism, establishing the relationship between the concentration of substance at the target site and the subsequent toxic effect can provide a tool for predicting toxicity. The behavior of a single toxicant could not be fully understood without the knowledge of the fact the physical and biochemical properties of substances that can change. To understand this, the acute toxicity of mercury (as HgSO₄) and silver (as AgSO₄) to Capoeta fusca (6 treatments in triplicate) was determined. During September 2009, C. fusca belonging to the family Cyprinidae, weighing 2.95 (±0.55) g, were obtained from qanats in Birjand, East of Iran. The fish were maintained in an aquarium system at a holding temperature of 21 (±0.2) and were allowed to adjust to lab conditions for 1 week before experimentation. The lethal concentration 50 (LC₅₀) values for HgSO₄ at 24, 48, 72, and 96 h of exposure were 0.32, 0.28, 0.26, and 0.24 mg L⁻¹, respectively. Also, the LC₅₀ values for AgSO₄ at 24, 48, 72, and 96 h of exposure were 0.014, 0.013, 0.013, and 0.013 mg L⁻¹, respectively. Results of this study showed that C. fusca was very sensitive to AgSO₄.

“…The effects of toxic substances, particularly heavy metals, on mortality rate and mortality period in aquatic vertebrates vary depending on the species, the metal, the environmental concentration of the metal, and the duration of exposure. In studies conducted on various fish species, it has been determined that the mortality rate increases in parallel with the increase in the toxin concentration in the environment and the duration of exposure (Abdullah et al, 2007;Gül et al, 2009;Alkahemal-Balawi et al, 2011). In the present study conducted on C. gariepinus, no mortality was observed in the fish under the conditions of time and concentration imposed.…”

This study was intended to determine the lead accumulation levels in liver, gill, kidney, brain, and muscle tissues of Clarias gariepinus (African sharp tooth catfish) under the sole effect of lead (1.0 and 2.0 ppm) and combined with EDTA (Ethylene diamine tetraacetic acid) (2.0 and 4.0 ppm) for 7, 15, and 30 days. Inductively coupled plasma mass spectrometry (ICP-MS) was used to determine tissue lead levels, and the SPSS package program was used for statistical evaluation of the experimental data. No mortality was observed in fish over the time periods of the experiments, and concentrations were determined with lead only and with lead together with EDTA. At the end of the experimental periods, the presence of lead increased the metal accumulation in the tissues and organs examined when compared to the control, and, in terms of accumulation, a relationship was determined between the tissues in the order of gill > kidney > liver > brain > muscle. The effect of lead together with EDTA was reduced lead accumulation in tissues and organs when compared to the effect of lead only.
