Abstract
Inductively coupled plasma mass spectrometry was used for the simultaneous determination of 8 heavy metals in water samples collected from Tinishu Akaki River, Ethiopia, and its tributaries during the period December 2002 to January 200 (first campaign) and November 2003 to January 2004 (second campaign). Accuracy was evaluated by analysis of certified reference materials. The differences between measured and certified values in SLRS-4, BCR 713 and BCR 714 were less than +/- 9% in most cases. The concentrations of 7 or 8 out of the 8 elements determined were statistically indistinguishable from the certified values. The ICP-MS precision was usually better than 5 % RSD. The limits of detection for most elements ranged from 0.001 to 0.01 ug L-1. The elemental concentrations measured, except for Cr and Mn, in Tinishu Akaki River water samples fulfill the surface water quality standard of class 2 4, and thus the water can be used for irrigation.
