Impact des infrastructures de transport (rail et route) sur la qualité des sols des jardins familiaux en Ile de France

Abstract : In urban and surroundings environment, kitchen gardens are mainly located in no constructible land with low values and agronomic, on disturbed soil may be contaminated. Frequently found along highways and railway, near the source of road/rail pollution. The study report attempts to examine whether there is a relationship between soil quality in kitchen gardens in Ile de France and proximity to infrastructure (rail and road). To do this, a database composed of studied substances (ETM, PAHs and THCs) and environmental parameters (age gardens, traffic density, speed of prevailing winds, topography and the presence of screens) was performed on 29gardens. This work showed that 6% of the samples exceed the maximum allowable lead in agricultural soils determined by the Ministerial Decree of 8 January 1998. In addition, a concentration gradient of lead and zinc in relation to the distance from the road was highlighted, and impact distance of 30 meters near the road has been found. In contrast, for total hydrocarbons (THCs) and polycyclic aromatic hydrocarbons (PAHs), no influence of road activity has been identified in soils.
