Résumé<br />

L’objectif <strong>de</strong> ce travail a consisté à une évaluation <strong>de</strong>s atteintes aux sols à vocation<br />

agricole et à végétation naturelle due à l’irrigation par les eaux chargés en métaux lourds, en<br />

provenance du barrage <strong>de</strong> Hammam Boughrara, d’oued Tafna et <strong>de</strong>s eaux usées <strong>de</strong>s égouts et<br />

ainsi <strong>de</strong>s rejets atmosphériques provenant <strong>de</strong>s axes routiers da la ville <strong>de</strong> Hammam Boughrara<br />

situé à 50 km <strong>de</strong> la ville <strong>de</strong> <strong>Tlemcen</strong>. Nous avons effectuée cette étu<strong>de</strong> aux cours <strong>de</strong> la saison<br />

<strong>de</strong> l’année 2006. Les extractions pratiquées sur les sols ont montré <strong>de</strong>s teneurs totaux<br />

supérieurs aux normes limites, générant ainsi une contamination par le zinc.<br />

Quant aux végétaux cultivé, l’étu<strong>de</strong> indique un risque potentiel écologique du blé dur,<br />

du poivron et du Maïs contaminée particulièrement par le Zn, le Pb et le Ni dans le blé dur, le<br />

maïs et par le Pb, le Co et le Cu dans le poivron, provenant ainsi <strong>de</strong>s risques potentiels pour la<br />

santé.<br />

Mots clés : blé dur, poivron, mais, métaux lourds, sol, contamination, extraction séquentielle.<br />

Abstract<br />

The objective of this work involved an assessment of damage to agricultural soils and<br />

natural vegetation due to irrigation water la<strong>de</strong>n with heavy metals, from the dam Boughrara<br />

Hammam, Wadi Tafna and sewage and waste water and air emissions from roads in the town<br />

of Hammam Boughrara located 50 km from the city of <strong>Tlemcen</strong>. We conducted this study to<br />

the season of 2006. Extractions performed on soils showed total concentrations above the<br />

standards limits, thereby generating a zinc contamination.<br />

As for the plants grown, the study indicates a potential ecological durum wheat,<br />

peppers and corn especially contaminated by Zn, Pb and Ni in durum wheat, corn and Pb, Co<br />

and Cu in pepper, and from the potential risks to health.<br />

Keywords: durum wheat, pepper, but, heavy metals, soil contamination, sequential extraction.<br />
