Evaluation of Activated Carbon for Treating Heavy Metals in Aquaculture

Aquaculture operations over the years have suffered a dramatic change because of the increasing levels of industrial and agricultural contaminants in the aquatic environment. Several methods have been studied to reduce the negative contribution of contaminated effluents in the ecosystem. The method...
