Description
In order to evaluate the environmental impregnation of toxic metals in the city of Marrakech (Morocco), the concentration of elements (Al, Pb, Cd and Hg) in the soil, water and children's nails was determined by ICPMS. The mean values of Al, Pb, Cd and Hg found in the children's nails were respectively (28.19±22.63; 4.08±2.69; 0.14±0.25 and 0.09±0.11). All these toxic metals concentrations were found to be lower than the optimal value required and lower than the published values. Moreover, the results indicated that the values (maximum and average) of concentrations of toxic elements (Cd, Hg) in the soils of all the sampling stations are lower than the limit values. While higher values of aluminum and lead were found in the soil. In water, among the four toxic elements, lead was the only one to exceed the limit values. Given the deleterious effects of toxic metals on human health, immediate measures must be taken to monitor and control the levels of contaminants including lead and aluminum in the city of Marrakech.
Key words: Aluminum, Lead, Soil, Water, Nails, Marrakech.
