Intérêt des cartes des sols pour l'élaboration d'une stratégie d'échantillonnage en sols contaminés par retombées atmosphériques : application à l'étude de l'effet sol sur le devenir des éléments traces métalliques ; Interest of soil maps to elaborate a sampling strategy in soils contaminated by atmospheric fallouts: application to the study of soil effect on the fate of metallic trace elements

peer reviewed ; As a result of pollution from atmospheric dusts, some sites of Wallonia (Belgium) are contaminated by metallic trace elements (MTE) such as cadmium, lead and zinc. These metalliferous soils are called ‘calaminary sites’. The major aim of this study concerns the multi-scalar characterization of MTE distribution in these contaminated soils and landscapes. The strategy of sampling described in this paper is based on the influence of soil type and its land use on the fate of MTE. After analysis of collected samples, it will be possible to have an idea of the distribution of MTE amo... Mehr ...
