The solid samples were carefully washed, dried and mineralized with nitric acid and hydrogen peroxide in a Digesdahl device. Metal concentration was determined by atomic emission spectrometry with an Agilent 7500a ICP-MS apparatus. In solid samples the levels of Cd varied from 0.02 to 0.45 μg/g, Cu from 0.15 to 13.53 μg/g, Fe from 0.075 to 1.700mg/g, Mn from 2.59 to 100μg/g, Pb from 0.47 to 5.76μg/g and Zn from 1.79 to 5.76μg/g. In water, mean metal concentrations were of μg/L levels, except Fe.
