“…The removal of polluted soils can contribute to another form of invisibilization. Thus, soils evacuated to the outskirts of Paris during the remediation of various neighborhoods in the nineteenth century have been reintegrated into the contemporary urban fabric for the implementation of development projects and green spaces [73]. In the Nantes region, waste rock from mining sites has been moved to be used as a fill for development operations (roads, community facilities, and buildings) [74].…”

“…Public actors play a real role in the reporting of soil pollution [73,77], however, NGOs and citizens' associations often constitute the levers of its visibility. The first national policies in Europe were envisaged after the denunciation by militant associations (Green Peace, Robin Hood, Legambiente) of serious industrial incidents (toxic landfill of Lekkerkerk in the Netherlands, Seveso accidents in 1976, Chernobyl and Schweizerhalle in 1986) [78].…”

Natural attenuation is described as a naturally occurring process, mostly in soils and also in groundwater, without human intervention, which transforms, reduces and destroys the organic and inorganic contaminants. As an eco-friendly, cost-effective and relatively simple technology, natural attenuation is widely used for the treatment of contaminated soils. However, the application of this technology must be carefully controlled and monitored not only for its efficiency and durability over time, but also for the migration of contaminants to ensure no risk to human health and ecosystems. Furthermore, the success of this technique requires a good knowledge of the type of contaminants, the physical and chemical characteristics of the soils, as well as the living actors, including plants, fauna, microorganisms and their interactions, that live in the soils to be treated and that will be involved in this process. The purpose of this chapter is to provide the most recent information regarding the principle of this technology, the role of the living actors and the interactions between plant, fauna and microorganisms, the advantages and disadvantages, and finally to discuss the efficiency of this technique in comparison with other techniques such as phytoremediation or bioremediation. In fine, we will discuss its social acceptability.

“…On a donc réimporté les pollutions qu'on avait autrefois rejetées à l'extérieur, sans oublier qu'entre-temps les maraîchers ont beaucoup utilisé de pesticides sur ce type de cultures. Le local n'est donc pas une ressource écologique toujours pertinente si on prend en compte l'historique du sol (péri)-urbain et l'héritage qui le constitue (Gitton et al, 2018).…”

“…In the vicinity of Paris, in the historically industrial region of the Ile-de-France, some agricultural soils were polluted with TM's following the disposal of Parisian sludge, and its use as a soil enrichment, a practice that reached its peak in the 19th century [15] [16]. Some of these soils are still cultivated today, through different forms of urban agriculture.…”

Within the context of a worldwide emergence of various forms of urban agriculture, there is a growing awareness concerning the health risks associated to the presence of different pollutants influencing the urban products safety. Among the most common pollutants found in soils and vegetables grown in the city, Trace Metals (TM's) are of major concern. This paper deals with risks assessment associated with the presence of TM's in soil, via two main exposure path ways: soil and vegetables ingestions. Risks assessments were conducted for various types of real scenarios encountered in three forms of urban farms near Paris (Ile-de-France Region). The farms have soil TM's levels in abnormally high concentrations (Pb (Lead), Cd (Cadmium), Hg (Mercury), Cu (Copper) and Zn (Zinc) contents higher than geochemical backgrounds and threshold values for sludge spreading, often used as reference values in France). The results of the Hazard Quotient (HQ)-based risk assessment approach (HQ defined as the ratio of estimated daily intake/tolerable daily intake) show that the most risky scenarios concern urban farmers (HQ tot = 1.02, because of the on-site working on a daily basis all year round), children gardeners (HQ tot = 1.29) and regular children consumers (HQ tot = 1.6 in maximalist scenario, where the consumer would exclusively consume the vegetables of the farm). Next would be the adult gardener scenario (HQ tot = 0.9), while the least risky are adult consumer scenarios (HQ tot = 0.62) and the farm workers (HQ tot = 0.45). For the highest risk scenarios (urban farmers and children), specific and drastic measures may be considered, such as reducing the site frequentation by sensitive populations (child and
