Evaluation de la contamination de plantes potagères cultivées dans un environnement potentiellement pollué : contexte actuel et propositions d'outils opérationnels

Abstract : The massive use of heavy metals and metalloids and their persistence in the environment can lead to contamination of ecosystems and their living organisms, including humans through the food they eat and especially their consumption of vegetables grown in kitchen gardens contaminated by these elements. Several approaches can be used to evaluate the contaminant contents of the edible parts of these vegetables (direct measurement, models of pollutant transfer, etc.). Until now, environmental risk assessors have had few operational tools to guide them through this analysis. The Agence de l'environnement et de la maitrise de l'energie (Ademe) and the Institut national de l'environnement industriel et des risques (Ineris), in collaboration with other research institutes, have analysed current practices and evaluated their deficiencies as part of a programme to develop such tools. This article presents an initial synthesis of this work and in particular of two new tools: A standardised sampling protocol for vegetables, intended to provide a global approach integrating the diversity of environments and measuring the contaminants inedible plant parts; A centralized database of information on the transfer of trace metals into the edible parts of vegetables, collected from recent scientific literature and ongoing diagnostic and experimental work. This database will be updated with new articles and reports
