Key words; - heavy metals, water, health and WHO
ABSTRACT: The study was undertaken to assess the status the metals in drinking water in the urban areas (Adigrat town) of the Tigray region, northern Ethiopia. A total of 7 drinking water samples were collected from the town. All the samples were analyzed for the two elements of Cu and Mn, using standard procedures and the results were compared with other international standards and WHO guideline values. Therefore, the results of the present study have shown the concentration all metals values (Mn with range of 0.139 to 0.427 mg/L and Cu with the range of 0 to 0.68 mg/l) were below the WHO (2009) recommended maximum admissible limits. Further works should be carried out in the toxic metal (like Pb, Cd, Cr etc) to check whether concentration is below or above the permissible level set by WHO guideline value.
