Metal concentrations in plants from mining areas in south morocco: health risks assessment of consumption of edible and aromatic plants

Abstract : The metals uptake by plants crops grown on garden soils surrounding three mining areas in South Morocco and the assessment of the potential health risk associated with human consumption of edible crops collected were investigated. Results indicated that high metal concentration of Co, Cr, Cu, Mn, and Ni in aerial parts of the aromatic plants and vegetables from mines A and B exceed the usual values reported in literature. The values of daily intake of metals (DIM) lower than oral reference dose (RfD) and health risk index < 1, indicating that the consumption of edible and aromatic plants grown in garden soils is relatively free of risks. However, consumption of the plants from mine A represents an average of 1% of RfD for Mn. This value is relatively important and remains high as compared to contribution of other food sources. The prevention of environmental risks associated with gardening in urban and industrial areas is necessary and essential to propose recommendations both to gardeners and to decision-makers.
