Determination of the Concentration of Dissolved Oxygen in Water Samples from Pankshin Town to Monitor Water Pollution.

Abstract

Concentration of Dissolved Oxygen in various water sample from three different water sources in Pankshin were determined to index the level of water pollution. The temperature of the water samples ranged between 24-30^oc. The P^H were within the range of 5.33-7.00. The amount of suspended solid (SS) and dissolved solid (DS) ranged from 0.03 x10³-0.15x10³ ppm and 0.05-0.10ppm respectively. Conductivity levels were in the range of 92-80µscm^-1. Dissolved oxygen (Do) had concentration range of 9.2-9.7 ppm. Of all the samples, the dissolved oxygen levels are within the acceptable limits of WHO. Pollution risk is therefore minimal.

Key words: Dissolved Oxygen, Conductivity levels, pollution.
