This research was conducted in Kenitra (northwestern Morocco) to determine the physicochemical parameters and metallic concentrations at three levels: surface water of Sebou and Beht intended for irrigation, agricultural soils and sugarcane. The spectrometric analysis of source plasma emission (ICP) has identified eight trace elements contained in the materials taken from zone 1 (As, Cd, Co, Zn, Ni, Pb, Cu and Cr).The obtained results showed that the interaction between the different physicochemical parameters of agricultural soils decides the transfer of the metal elements to the plants. Indeed, for the soil which is used in this agriculture (for sugar cane), its irrigation water, and the contents of Cr, Cd and As exceeds the accepted standards.The principal component analysis of the levels of trace metal supports in area 1, allowed to distinguish between the items with a high tolerance for bagasse (Zn, Cu, Ni, Cd and Pb), compared to Cr, Co, and As. |
