Heavy metals are micro likely to cause nuisance even when they are released in very small quantities (toxicity develops through bioaccumulation). Moreover, small amounts are often offset by a volume effect into account the importance of water flow. The industry is responsible for almost all releases of heavy metals in water. In effect, water rivers, streams, canals, the sea has long been "outlet" that allowed to evacuate waste. This work focuses on the analysis and evaluation of metal contamination of raw sewage drained by three main collectors Oued R'dom (Morocco) through the spatio-temporal monitoring of the levels of some metals (Pb, iron, Zn, Cd, Cu and Cr). Sampling was conducted for one year from January to December 2013. Analysis of Fe, Zn, Cd, Pb, Cr and Cu revealed the presence of metal contamination from the Fe exceeded the threshold of acceptability, other metallic trace element exist in quantity accepted, they could be classified in order of abundance in the following manner: Fe> Zn> Cd> Pb> Cu> Cr. The average concentrations of metals Oued R'dom level in water are 3.11 mg / l for Fe, 2.17 mg / l for Zn, 0.046 mg / l for Pb, 0.01 mg / l for Cr, 0.043 mg / l for Cu and 0.083 mg / l for Cd.

Abstract: (french)
Les métaux lourds sont des micropolluants de nature à entraîner les nuisances, leur toxicité se développe par bioaccumulation même quand ils sont rejetés en quantités très faibles. D'ailleurs, de petites quantités sont souvent compensées par un effet volume compte tenu de l'importance des débits d'eau. L'industrie est responsable du quasi totalité des rejets de métaux lourds dans l'eau. En effet, l'eau des fleuves, des rivières, des canaux, de la mer a longtemps été « l'exutoire » qui permettait d'évacuer ces déchets. Ce travail porte sur l'analyse et l'évaluation de la contamination métallique des eaux usées brutes drainées par les trois principaux collecteurs d'Oued R'dom (Maroc) à travers le suivi spatio-temporel des teneurs de certains éléments métalliques (Pb, Fer, Zn, Cd, Cu et Cr). L'échantillonnage a été effectué pendant une année depuis janvier à décembre 2013. L'analyse en Fe, Zn, Cd, Pb, Cr et Cu révèlent la présence d'une contamination métallique à part le Fe qui a dépassé le seuil d'acceptabilité, les autres éléments trace métalliques existent en quantité admise, ils pourraient être classés par ordre d'abondance de la manière suivante : Fe > Zn > Cd >Pb> Cu > Cr. Les concentrations moyennes de métaux au niveau d'Oued R'dom dans l'eau sont de 3,11 mg/l pour le Fe ; 2,17mg /l pour le Zn ; 0,046mg/l pour le Pb ; 0,01mg/l pour le Cr ; 0,043 mg/l pour le Cu et 0,083 mg/l pour le Cd.
