Determination of heavy metal and their distribution in River Nile

The methods used nowdays for the determination of heavy metals in environment samples involve highly sensitive spectroscopic techniques,such as atomic absorption spectroscopy and inductively coupled plasma-mass spectrometry(ICP-MS ).The aim of this work was to evaluate two different techniques (ICP-MS and XRF)for the determination of total concentrationof 13 metals in surface sediments and soils samples collected from Rive Nile and its tributaries around Khartoum City (Sudan).
