Doctoral thesis on “The association of hyperaccumulative plants and vegetable plants as a strategy for reducing the translocation of metals to the organs consumed”.

With the development of urban gardening in many cities around the world, the contamination of vegetable plants by metals and metalloids is a cause for concern. The aim of my work is therefore to develop innovative cropping systems adapted to the soils of contaminated vegetable gardens by combining hyperaccumulative plants with market garden crops in order to reduce the transfer of metals to the organs consumed. The aim of the work is to better consider the role of the rhizosphere and inter-species interactions in assessing the bioavailability and uptake of metals by both vegetable and hyperaccumulator plants. To achieve these objectives, work is being carried out at pot scale under controlled conditions and in the field.
