Abstract
Metal contamination of soils, following local atmospheric deposition (industrial and urban) and to different inputs (compost, manure ...) or former explains in particular the presence in surface horizons, current levels ETM such as Cd, Cu, Zn and Pb. However, despite the obvious effect of accumulation, transfer of metal to the depth is also noted, usually deducted from total contents comparisons metals in different soil horizons. Among the cited metallic elements, some are essential trace elements such as zinc (Zn) and copper (Cu), but become toxic at high concentrations. Others such as lead (Pb) and cadmium (Cd) are toxic when trace. Their accumulation and transfer in the soil on the site of Penga Penga-therefore a risk to human health through contamination of the food chain but also for the environment as a whole.

Abstract: (french)
La contamination métallique des sols, suite aux retombées atmosphériques locales (industrielles et urbaines) et à des apports divers (composts, engrais…) anciens ou actuels, explique notamment la présence dans les horizons de surface, les teneurs actuelles en ETM tels que Cd, Cu, Zn et Pb. Cependant, malgré un effet d’accumulation évident, le transfert de métaux vers la profondeur est également noté, le plus souvent déduit à partir de comparaisons des teneurs totales en métaux dans les différents horizons d’un sol. Parmi les éléments métalliques cités, certains sont des oligo-éléments essentiels comme le zinc (Zn) et le cuivre (Cu), mais deviennent toxiques à fortes concentrations. D’autres comme le plomb (Pb) ou le cadmium (Cd) sont toxiques dès l’état de trace. Leur accumulation et leur transfert dans le sol, sur le site de Penga-Penga constituent donc un risque pour la santé humaine via la contamination de la chaîne alimentaire, mais aussi pour le milieu naturel dans son ensemble.
