Abstract
The increasing use of heavy metals in industry in the modern world unfavorably affects the aquatic environment. Acute toxicity of nickel to the fresh water fish carassius auratus was determined using Probite analyze, Fish were exposed to selected concentration of nickel and the mortality data were determined after 24, 48, 72 and 96 hours. LC50 values for 24,48,72 and 96 hours were calculated with the 95% fiducially limits. The 24,48,72 and 96 hours LC50 values of nickel to the fish were 161.78 ± 3.05, 130.58 ± 2.32, 110.19 ± 1.57, 100.39 ± 0.54 ppm respectively. White blood cell (WBC) count, hemoglobin (Hb) and hematocrit (Hct) level were significantly reduced at experimental concentrations (p 0.05). In summary, nickel intoxication resulted indicated that hematological and biochemical parameters can be used as an indicator of nickel related stress in fish on exposure to elevated nickel status.
Highlights
One of the most prominent natural resources is water that its regular supply is extremely much essential for the survival of all living animals
This indicates an increase in toxicity with exposure duration
It is apparent from the outcome that the heavy metal concentration has a direct effect on the LC50 values of the respective fish
Summary
One of the most prominent natural resources is water that its regular supply is extremely much essential for the survival of all living animals. In the different industries greatly used heavy metals in some industries of the new world adversely affect the aquatic animals after eject of the waste material into water [1]. The improvement coefficient of this metal in the food chain arrived extreme. The important action of the environmental toxicologist is to assess impartially the endanger obtained from the presence of such materials. These materials may alter the quality of water and desecrate the fisheries management [2,3]
