Impact of the Controlled Dump of Fez City (Morocco): Evaluation of Metallic Trace Elements Contamination in the Sediments

In order to qualify and quantify the impact of sediment contamination in hydric settings by metallic trace elements (MTE) emanating from controlled dump Fez city (northern Morocco), leachate sample analyses were carried out. The leachates collected 24 sites are characterised a pH between 6.91 8, COD varying 430.7 7962 mg/L, an NTK content up 1955 with average 1514 nitrate concentration reaching 46 mg/L some samples, which exceeds standards for discharges into natural environment. chromium mainly household waste varies 1.69 4.90 mg/L. MTE (As, Cd, Co, Cr, Cu, Ni, Pb, Zn Fe) different one basin another. sediments downstream along sampling profile show values 7.34 8.21 (compared 7.96–8.82 reference samples), electrical conductivity fluctuate 1.21 ms/cm 5.37 contaminated 0.8 sediment). analysis ICP-AES shows that their slightly point Furthermore, they do not vary considerably surface (0 cm) depth (20 cm). element concentrations 45.83 ± 2.14 mg/Kg 4.40 0.07 43.76 3.40 72.99 1.85 21.71 6.55 Pb 102.02 7.28 mg/kg Zn. effect, negative environmental dumping site is ostensibly underlined both (i) pollution load index values, indicate strong progressive deterioration thalweg, (ii) statistical (PCA), reveals common origin deduced pollutants through correlation majority analysed elements.
