Determination of physico-chemical parameter and trace metal contents of drinking water samples in akure Nigeria

Abstract

The physico - chemical and trace metal contents of water samples from Akure, Nigeria were assessed using atomic absorption spectrophotometery. Results indicated that low variation existed among some physico -chemical parameter (pH, temperature, conductivity, dissolved oxygen and nitrate). In the water sample oil and grease, taste and odor were not detected .The mean levels (mg L-1) of the metals ranged thus; 4.8(Fe), 0.3 (Cr), 0.1(Cd), 0.2(Pb), 0.2(As), 0.1(Ni). However, Co and Zn were not detected. Comparison of the metal contents in the water sample with WHO limits showed that the mean levels of all the metals were below the maximum permissible levels for drinking water.
