Abstract

The objective of this work was to assess the quality of different categories of water intended for human consumption through monitoring and quantification of metallic trace elements. Chosen study matrix was made up of tap water, bottled Moroccan water, bottled foreign water and finally surface water from Beni Mellal area: Ain Asserdoune and Bouyakoub. Four trace elements were studied namely: As, Cd, Cr and Pb. The assays were carried out using inductively coupled plasma technique equipped with Atomic Emission Spectrometer (ICP-AES). Dissimilarities between waters and correlations between metallic trace elements were carried out by Principal Component Analysis. According to the analytical results, Arsenic (As) would be much more present in foreign waters with an average value of 6.33µg/L followed by Moroccan surface water category with an average value of 6.191 µg/L. Cadmium (Cd) was also more present in Moroccan surface water category. Chromium (Cr) was much more present in Moroccan waters especially in natural water category with an average value of 45.65 µg/L followed by tap water with of 44.875 µg/L value. Lead (Pb) was much more present in Moroccan waters compared to foreign waters. Analysis results allow us to locate the different samples analyzed in relation to Moroccan drinking water standard and that of World Health Organization on the one hand and to classify different types of water according to their concentrations of metallic elements on the other hand.
