Investigation of some trace elements in drinking water: Nuba Mountains Section, Sudan

Abstract

This study was conducted to assess the extent of pollution in the drinking water from various sources at the area of the Nuba Mountains, Sudan. 42 samples were collected from hand pump stations, water yard (diesel machine) stations and surface water (lake) stations.These waters were analyzed using atomic absorption spectrophotometer. The concentrations of iron, nickel, copper, manganese, magnesium, zinc and chromium were determined using flame atomic spectroscopy, while the concentrations of cadmium and lead were determined by furnace atomic spectroscopy. The mean concentrations of iron, nickel, lead, copper, manganese, magnesium, zinc and chromium in water samples collected from hand pump stations were 1.901, 0.010, 0.1310, 0.0070, 0.0410, 20.35, 0.558 and 0.0430 mg/L respectively. And in samples collected from water yard stations were found to be 0.871, 0.013, 0.438, 0.209, 0.128, 28.41, 0.103 and 0.032 mg/L for iron, nickel, lead, copper, manganese, magnesium, zinc and chromium respectively. And in samples collected from surface water station were found to be 13.74, 0.023, 0.015, 0.017, 0.118, 7.008, 0.042 and 0.0002 mg/L for iron, nickel, lead, copper, manganese, magnesium, zinc and chromium respectively. The concentrations of cadmium were found below detection of limits. Mean concentrations of elements from different sources were compared using the  More>>

The concentrations of cadmium were found below detection of limits. Mean concentrations of elements from different sources were compared using the Kruskal - wallis method. This study showed that there are significant different between mean concentrations for these elements. The spear man correlation method was identified between elements. Correlation study shows that there is a significant positive correlation between iron and chromium. Comparison between those data and the specific criterion specifies drinking water by the World Health Organization (WHO) showed that the concentrations of Pb are exceeding the maximum permissible levels in eighteen stations. Violations of drinking water limits were observed also for the elements Mn in six stations and Cr in seven stations, there are only one stations showed violation for Cu and again another station showed violation for Zn. Comparison study between our results and that were found in Britain, Norway and Nigeria showed that the mean concentrations of Ni and Cd were found to be lower than what had been found in the above mentioned countries. However the mean concentration of Fe, Cr, Pb, Zn, Cu, Mg and Mn were found to be higher than were found in these countries.(Author)}
