Abstract

Phytoextraction, a plant-based alternative and/or complementary technology used to remedy contaminated soil, has been the focus of attention due to its potential utilization in brownfield areas. The applicability of phytoremediation was evaluated on soil from a brownfield site contaminated by As. Among the technological alternatives, assisted phytoextraction is a strategy for enhancing the bioavailability of contaminants for subsequent plant uptake, by applying chemical additives to the soil. The potential of phosphate fertilizer (biammonium phosphate) for enhancing As availability and uptake by plants (Lupinus albus), was evaluated on the microcosm scale. Lupin was grown on Ascontaminated soil (533 mg kg–1) collected from a manufactured gas plant (MGP site). E
