Description

The occurrence of heavy metals viz., copper, zinc, iron and manganese in surface water samples were measured in 6 fish ponds at Bhadra fish farm of Karnataka. The heavy metals were measured using Atomic Absorption Spectrophotometer (AAS). Average value of iron (Fe) in water samples is exceeding as per KSPCB standards in all the ponds except pond 1. In the present investigation Mn levels in the water samples varied from 5.0 to 99 mg/l respectively. Its concentration was higher than the world average values in Pond 3. Heavy metals in the order of their relative dominal were in the sequence Fe >Mn > Zn > Cu respectively.
