Determination of lead and cadmium in drinking water at Khartoum state by atomic absorption spectroscopy

Abstract EN

The purpose of this study is to analyze drinking water in Khartoum state different location.

The Importance of the study is to determine the impact of pollution in the environment at Khartoum state.

The samples of water were collected classified for three groups, according location; residential, Agriculture and industrial area in Khartoum, Bahri and Omdurman and were treated, and analyzed using atomic absorption spectroscopy (AAS) and other analytical tools with standard methods for determination of heavy metals; cadmium and lead.

The results of cadmium con- centration are in Omdurman; residential, agriculture and industrial areas are, (0.022 to 0.036 mg 1-1, 0.032 to 0.038 mg 1-1 0.026 to 0.030 mg 1-1).

Respectively.

In Bahri; residential, agriculture and industrial areas are (0.027 to 0.031 mg 1-1;, 0.034 to 0.492 mg 1-1, 0.018 to 0.035 mg 1-1 in industrial areas) Respectively.

In Khartoum; residential, agriculture and industrial areas are (0.

024 to 0.031 mg 1-1, 0.030 to 0.037 mg 1-1, 0.030 to 0.034 mg 1-) Respectively.

The lead was not indicated in all the samples.

The research has revealed that levels of cadmium in Khartoum state are higher than maximum limit levels of World Health organization.

In addition, cadmium levels in water at agriculture areas were highest from residential and industrial areas; This is due to the use of phosphate fertilizers in these areas.
