[ 1 ] - Environmental effects of the cold water fish farms effluents on the water quality of Gamasyab River as their main source of water supply in the west of Iran

Rainbow trout (Oncorhynchus mykiss) is one of the most-widely cultivated cold fresh water fish in the world. Gamasyab River, with a length of about 200 Km, is one of the longest rivers of Iran. The aim of this research is to determine the effects of trout farm effluents on this river water.  From a total of 24 trout farms in the area,  four farms were randomly selected and three sampling statio...

[ 2 ] - Study of the heavy metals (Cd and Pb) content in the tissues of rainbow trouts from Hamedan coldwater fish farms

The aim of this research was to determine the concentration of cadmium (Cd) and lead (Pb) in the muscle and liver tissues of rainbow trout (Oncorhynchus mykiss) in Hamedan Province (west of Iran) cold water fish farms, and compare the results with the FAO/WHO guidelines. Heavy metal concentrations were determined from the three randomly selected fish farms by Inductively Coupled Plasma Optical ...

[ 3 ] - Kinetic study of heavy metal ions removal from aqueous solutions using activated pumice stone

Background: The presence of heavy metals in aquatic and terrestrial ecosystems causes harmful effects to living organisms in the environment. This research aimed to determine the potential of activated pumice stone (APS) as a sorbent for the removal of Cd, Cu, and Zn from wastewater. Methods: This research was conducted during 2013 on a laboratory scale. The study was performed using batch exp...
