Factors controlling the spatial distribution of arsenic in topsoils developed on an iron-rich parent material in Belgian Lorraine

In topsoils, high levels of potentially toxic elements such as arsenic, may pose a problem to human health as they can be transferred through the food chain. High arsenic levels are typically found over large areas in soils developed on iron-rich parent material, such as in the soils developed on the Aubange formation (southern Wallonia, Belgian Lorraine). Anticipating the occurrence of arsenic levels in these areas affected by elevated background concentration is of interest both for improving scientific knowledge of soil geochemistry, and for soil protection management. Here we studied the g... Mehr ...
