The aim of this work is to study the mobility of polycyclic aromatic hydrocarbons, mainly naphthalene, in an agricultural soil in road environment. The recorded naphthalene concentrations in soil’s surface horizons (19.37 ± 0.32 mg∙g-1), allowed to highlight that the traffic and road’s infrastructures are an important toxic source of naphthalene to the environment. This pollutant can disperse and fall dry or wet on the edges of the pavement, carried by storm water runoff into the ground. This naphthalene accumulation is influenced by the physical and chemical parameters of the soil (pH, cation exchange capacity, clays rate). High levels of naphthalene in soil were observed at low pH (r = -0.25**), in contrast, soil cation exchange capacity (CEC) and the clays rate are positively correlated with these levels (r = 0.20* and r = 0.17**).
