“…Soil DDTs levels increased from 518 ng g −1 dw (day 1) to 1143 and 823 ng g −1 dw at 15 and 60 days, respectively. Pollutant enhancement by watering regimen in this soil was previously reported by Mitton et al (2012) and this behavior was also informed for other soils and compounds (White et al, 1998;Kottler et al, 2001). The reason for the changes associated with the additions and losses of water from soil are uncertain.…”

“…This could be explained by a specific root exudates production having a specific Pb mobilizer effect, which could favor Pb soil desorption favored by biochar addition (Kidd et al, 2009), since studies have shown that root exudates may differ among species (Kidd et al, 2009) and among amendments used (Mitton et al, 2012). …”

Mining activities lead to widespread environmental pollution of terrestrial ecosystems due to the presence of metal(loid)s in tailings. These contaminated areas present a health risk and hence need to be rehabilitated. Ex situ methods for soil remediation have been used for a long time but are expensive and disruptive to soil. Phytoremediation techniques for the stabilization or extraction of metal(loid)s could be an efficient alternative as they provide a low-cost and environmentally friendly option. A C C E P T E D M A N U S C R I P T ACCEPTED MANUSCRIPTHowever, due to the often poor nutrient content of these contaminated soils, amendments must be added to enhance plant growth and to improve phytoremediation efficiency. Biochar, a pyrogenic product, is a promising amendment for assisted phytoremediation. The aims of our study were (i) to evaluate the effect of a pinewood biochar on the physicochemical properties of a former mine contaminated technosol, (ii) to assess the mobility and phytoavailability of As and Pb and (iii) to investigate the remediation potential of three willow species (Salix alba, Salix viminalis and Salix purpurea). A greenhouse experiment was conducted with contaminated technosols amended with biochar and garden soil, single or combined, revegetated with the 3 willow species. The physicochemical properties of soil pore water (SPW) as well as metal(loid) concentrations were determined. Plant growth, Salix organ dry weight and metal(loid) uptake were determined in order to evaluate the phytoremediation potential of the three Salix species studied. Biochar increased the pH and electrical conductivity of SPW. Biochar addition had no effect on As mobility but decreased SPW Pb concentration by 70%. For the three Salix species investigated, biochar addition to the polluted soil induced a better growth and a higher dry weight production. In most modalities tested, the metal(loid)A C C E P T E D M A N U S C R I P T ACCEPTED MANUSCRIPTcontent in the Salix organs increased due to the biochar application. Globally, a positive effect of biochar was noticed on the soil qualities (pH and electrical conductivity increase) and plant growth.Metal(loid)s were mostly confined to the roots. Amon...

“…To evaluate the removal of azoxystrobin from the soil, five treatments were performed in this experiment, and each treatment consisted of five replicates: (1) azoxystrobincontaminated soil without plants, (2) azoxystrobin-contaminated soil with P. major only (each pot contained one seedling of P. major), (3) azoxystrobin-contaminated soil with H. annus seedling (each pot contained twenty seedling of H. annus), (4) azoxystrobin-contaminated soil with soybean plants (each pot contained twenty seedling of G. max) and (5) azoxystrobin-contaminated soil with P. major and amended with polyoxyethylene sorbitan monooleate (Tween 80) at 9.2 mg/L, corresponding to 0.5 critical micelle concentration (CMC), where the CMC of Tween 80 was determined as 13-45 mg/L (Edwards et al 1991;Mitton et al 2012) (each pot contained one seedling of P. major). A whole-plant uptake experiment was performed on soil in a pot experiment for 14-day exposure.…”

Azoxystrobin is a broad-spectrum, systemic and soil-applied fungicide used for crop protection on more than 80 different crops. Azoxystrobin use has induced water pollution and ecotoxicological effects upon aquatic organisms, as well as heath issues. Such issues may be solved by phytoremediation. Here, we tested Plantago major L., Helianthus annus L. and Glycine max L. to clean soils under laboratory conditions. Results show that the accumulation efficiency of azoxystrobin and azoxystrobin acid in roots was higher than those of leaves. G. max roots were an efficient accumulator of azoxystrobin (25.32 mg/ kg), followed by P. major roots (20.62 mg/kg) and H. annus roots (18.29 mg/kg), within 10 days, respectively. In the leaves, azoxystrobin significantly translocated into the P. major leaves and reached the maximum after 10 days of exposure (15.03 mg/kg), followed by H. annus leaves (9.8 mg/kg), while it reached the maximum after 3 days of exposure (3.12 mg/kg) in G. max leaves. Azoxystrobin acid significantly accumulated in P. major roots more than the G. max and H. annus roots. In the leaves, azoxystrobin acid significantly accumulated in G. max more than P. major and H. annus. The presence of P. major with Tween 80 had effects on azoxystrobin desorption from soil, plant uptake metabolism and translocation more than P. major alone.
