  abstract = {{T}he fate of nanoparticles ({NP}s) in soil under relevant environmental conditions is still poorly understood. {I}n this study, the mobility of two metal-oxide nanoparticles ({C}u{O} and {T}i{O}2) in contrasting agricultural soils was investigated in water-saturated soil columns. {T}he transport of {T}i{O}2 and {C}u{O}-{NP}s were assessed in six soils with three different textures (from sand to clay) and two contrasted organic matter ({OM}) contents for each texture. {T}i{O}2 mobility was very low in all soils, regardless of texture and {OM} content. {M}ass recoveries were always less than 5%, probably in relation with the strong homo-aggregation of {T}i{O}2-{NP}s observed in all soil solutions, with apparent sizes 3-6 times larger than their nominal size. {T}his low mobility suggests that {T}i{O}2-{NP}s present a low risk of direct groundwater contamination in contrasted surface soils. {A}lthough their retention was also generally high (more than 86%), {C}u{O} nanoparticles were found to be mobile in all soils. {T}his is probably related to their smaller apparent size and lowcapacity of homo-aggregation of {C}u{O}-{NP}s in all soil solutions. {N}o clear influence of neither soil texture or soil total organic matter content could be observed on {C}u{O} transport. {H}owever, this study shows that in contrasted agricultural soils, {C}u{O}-{NP}s transport is mainly controlled by the solutes dissolved in soil solution ({DOC} and {PO}4 species), rather than by the properties of the soil solid phase.},
