Determination of Some Physiochemical Parameters and Selected Heavy Metals from Water Collected from Concrete Fish Ponds in Ozoro Town

Abstract

Four samples of different fish pond were analyzed for physiochemical properties. The pH ranged from 6.8 to 7.4; Temperatures
ranged from 25oC to 27oC; Conductivity ranged from 148.2 to 191.2µs/cm; TDS ranged from 21.3 to 28.6mg/L; TSS ranged from 63.1to 74.7 mg/L; DO ranged from 7.5 to 9.3mg/L; BOD ranged from 2.01-4.01mg/L; Alkalinity ranged from 26.9 to 36.1 while
Total Hardness ranged from 2.4 to 3.6. Five heavy metals, Zinc, Nickel, Lead, Iron and Copper were analyzed for different four
fish ponds. The concentration of zinc ranged from 0.013 to 0.015mg/L; Nickel ranged from 0.01 to 0.03mg/L; Lead ranged from 0.18 to 0.23mg/L; Iron ranged from 0.29 to 0.48mg/L and copper concentration ranged 0.02 to 0.07mg/L. all the parameter analyzed were within the WHO maximum acceptable concentration in ponds are fit for fish production.
