“…This result highlights the strong interactions that are widely described between copper and OM in soils and sediments [13]. Different sequential extraction studies have demonstrated the presence of copper mainly in the following compartments: residual fraction > bound to Fe-Mn oxides > bound to organic matter > bound to carbonates [14] [33] [34] [35]. In those studies, there are few amounts of leached copper.…”

Urban sediment generated by stormwater management techniques are highly contaminated with various trace elements. The characterization of trace element speciation and mobility are critical information to improve environmental risk assessment. This study investigates the spatial and temporal variability of major and trace element release from a sedimentary layer in Django Reinhart stormwater infiltration basin (Chassieu, eastern suburbs of Lyon, France). Sampling was conducted for 3 zones and two dates. Chemical characterization was performed (X-Ray diffraction, ICP-AES). The samples were submitted to Acid Neutralization Capacity & Base Neutralization Capacity ANC-BNC tests, according to European standard 14429 (AFNOR, 2015). Solid matrices were mixed with acid or basic solutions and physicochemical parameters and major and trace element release (i.e. Al, Ca, Fe, P, S, Si, Cu, Zn and total carbon) were followed as a function of pH. The results show that the urban sediment has no significant spatial and temporal variability with regards to element release. This observation is all the more surprising that the samples were collected in three contrasting zones regarding stormwater supply and hydric conditions. Element release follows the same trends as a function of pH with a bell-shaped solubilization curve exhibiting the highest solubility at extreme pH values. However, the samples showed slight differences concerning the release of major elements. Such differences are related to slight differences in total mineral contents (organic matter, carbonates…) and chemical composition of the sediments. The results show that despite the varying environmental conditions, the sediment chemical properties can be considered as very stable and uniform over space, dependent mainly on the local geochemical context and watershed characteristics.

To assess the roadside soils contamination with Pb, Cd, and Zn, 34 soil samples were collected along Alexandria-Marsa Matruh highway, Egypt, and analyzed by using the atomic absorption. The contamination with these metals was evaluated by applying index of geoaccumulation ( geo ), contamination factor (CF), pollution load index (PLI), the single ecological risk index ( ), and the potential ecological risk index (PERI). The average concentrations of Pb, Cd, and Zn were 38.2, 2.3, and 43.4 g/g, respectively.geo indicates the pollution of soil with Pb and Cd as opposed to Zn. shows that the roadside soils had low risk from Pb and Zn and had considerable to high risk from Cd. Most of the samples (62%) present low PERI risk associated with metal exposure and the rest of the samples (38%) are of moderate PERI. The bioavailable fraction (EDTA-Extract) was 72.5 and 37.5% for Pb and Cd contents, respectively. These results indicate the remarkable effect of vehicular and agricultural activities on Pb and Cd contents in soil.

“…Le rutile est la forme principale du titane en milieu urbain (Clozel et al, 2006 ;Kaegi et al, 2008) Par contre, on perçoit bien l'importance des formes colloïdales du titane qui vont être responsables de sa mobilité potentielle dans les sédiments urbains. Cette mobilité reste toutefois très faible par rapport à la mobilité potentielle d'autres métaux lourds préalablement étudiés sur ces sédiments comme le cuivre (Saulais et al, 2011).…”

RÉSUMÉ MOTS-CLÉS : sédiments urbains, titane, mobilité potentielle, signature géochimique ABSTRACTTitanium is largely used in the urban environment. The purpose of this study is to characterize the titanium geochemical signature in urban stormwater sediments. Firstly, we compared the titanium, iron, silica, copper, zinc and lead content in 800 river sediments collected in Europe with the content of 19 urban sediments collected in stormwater infiltration basins in Lyon. Even if the total titanium content is not higher in urban sediment (mean of 2,7 g/kg) than in river sediments (1,5 à 4,0 g/kg), urban sediments concentrate titanium in comparison to other main minerals like silica and is correlated to heavy metals. Thus, the urban environment produce eroded particles that have a specific geochemical signature. Secondly, the study of the potentiel soluble or colloïdal mobility of titanium in urban sediment through batch experiments shows that titanium has a very low mobility in soluble or colloïdal form (less than 0,005% of the total titanium content). The organic matter present in urban sediment is supposed to play a major role on the limitation of the mobility of colloïdal titanium.
