Amelioration the Toxic Effects of Cadmium-Exposure in Nile Tilapia (Oreochromis Niloticus) by using Lemna gibba L
Cadmium is an extremely toxic metal. It is widely used in mining, metallurgical operations, electroplating industries manufacturing vinyl plastics which used in metallic and plastic pipes. Effluents from such activities are sources of cadmium into aquatic environments. Most aquatic organisms have the capability of concentrating metals by feeding and metabolic processes, which can lead to accumulation of high concentrations of metals in their tissues. Metals interact with legends in proteins particularly, enzymes and may inhibit their biochemical and physiological activities.
The levels of contamination by cadmium in fish are of considerable interest because fish consumption is an important source of intake cadmium for the general population. Most of the cadmium content in fish or other seafood is highly absorbable in humans; the efficiency of gastrointestinal absorption of cadmium has been reported to be approximately 3-8% of the ingested load. Cadmium is particularly accumulated in kidney and to lower extent in muscles.
