Abstract

Trace Metal composition of the Bottled water that available in Erbil city was assessed during January to April-2010 from different shops of the city. About ten bottled water samples were analyzed using Atomic Absorption Spectrophotometer for their Aluminum, Cadmium, Lead, Iron, Copper and Manganese content and their levels compared with World Health Organization specified maximum contaminant level. According to the WHO, the Maximum Contaminant Level (MCL) for Aluminum, Cadmium, Lead, Iron, Copper and Manganese are 0.2, 0.003, 0.01, 1, 2 and 0.5mg/L respectively. From the results obtained, none of the samples analyzed contained Aluminium in concentrations above the MCL, however, the metal was found to be present in 50% of the samples analyzed. Over 30%of the samples had Cadmium concentrations above the MCL. Almost 75% of the samples had detectable level of Lead while 40% of the sample had Lead concentration above the MCL. The results demonstrated that all of samples Iron, Copper and Manganese concentrations have been shown below MCL according to WHO. The analysis performed by Atomic Absorption Spectrophotometer, indicated that mostly the trace element were below the WHO guideline, except 30% and 40%of the samples had Cadmium and Lead concentrations above the MCL respectively.
