Influence of pH and water hardness upon nickel accumulation in edible fish Cirrhinus mrigala.

چکیده
The freshwater fingerlings of Cirrhinus mrigala were exposed to Nickel in acidic medium pH = 6.0 (5.8-6.2), alkaline medium pH = 9.0 (8.8-9.2) and water hardness (40 mg/l) of CaCO3. The study indicates that nickel accumulation was significantly influenced by pH and hardness of water The concentration was found to be significantly higher at pH = 9.0 than at pH = 6.0. Also the presence of hardness in water results in reduced toxicity of nickel.

Aberrations in the Chromosomes of Cirrhinus mrigala (Hamilton) upon Exposure to Butachlor
Background: Cirrhinus mrigala, one of the important fish widely consumed in India, was used for karyological observations and to evaluate the toxic effect of butachlor, an extensively used herbicide in rice fields in terms of chromosomal aberration test. Methods: Fishes were collected from “National Fish Seed Farm” Jyotisar with mean body weight of 20-50g. The experimental fishes were kept i...

Metals are the major pollutants in aquatic environment. A lot of research literature is available globally about accumulation of heavy metals in aquatic ecosystems as well as in different body organs of aquatic animals, especially fish. Heavy metals mainly generate reactive oxygen species (ROS) in aquatic animals that lead to oxidative stress production. ROS cause oxidative damage to different ...
