Abstract. Polycyclic aromatic hydrocarbons (PAHs) are persistent organic pollutants produced by anthropogenic activities that contaminate all environmental spheres, including soils. This study focused on PAHs measured in 2154 soils in France, covering the entire territory based on a regular sampling grid. The quantified concentrations in the Σ15PAHs ranged from 5.1 to 31200 µg · kg−1, with a median value of 32.6 µg · kg−1, and PAHs were detected in 70 % of the soil samples. The map of Σ15PAHs concentrations revealed strong spatial variations in soil contamination throughout France, with larger concentrations in soils of industrial regions and near major cities. PAHs molecular diagnostic ratios supports the historical origin of PAHs in the northern part of France being linked to the significant emissions of PAHs in Europe during the industrial period of 1850–1950 with in particular the contribution of coal/biomass combustion and iron-steel production. A health risk assessment conducted for the residential population resulted in a median value of 1.07 × 10−8 in total lifetime cancer risk, with only 20 sites above the limit of 10−6 and one above the limit of 10−5 adopted by the French government. These results reveal the need to conduct large-scale studies on soil contamination to determine the fate of PAHs and evaluate the risks induced by soil pollution at a country-level scale.

Short summary
Pollution of French soils by polycyclic aromatic hydrocarbons (PAHs) known as carcinogenic pollutants was quantified in this work using an extended dataset of 2154 soils sampled across France. The map of PAHs concentrations in French soils revealed strong trends in regions with heavy industries and around cities. The PAHs signatures indicated the influence of PAHs emissions in Europe during the industrial revolution. Health risks posed by PAHs in soils were low but need to be considered.
