| 1 | Assessment of compost and three biochars associated with Ailanthus altissima(Miller)Swingle for lead and arsenic stabilization in a post-mining Technosol显示文摘The elevated presence of metal(loid)s in the environment significantly impacts ecosystems and human health and is generally largely due to industrial and mining activities.Thus,in the current study,we investigated and proposed an environmentally friendly method(phytomanagement)aimed at reducing the negative impacts associated with metal(loid)pollution through the use of soil amendments(biochar and compost)to permit Ailanthus altissima growth on a highly contaminated mining Technosol,with arsenic(As)and lead(Pb)contents of 539.06 and 11453 mg kg^(-1),respectively.The objective was to examine the impacts of three biochars and compost on i)the physicochemical characteristics of soil,ii)metal(loid)immobilization in soil,and iii)A.altissima growth.We revealed that the application of biochar as a soil amendment improved soil conditions by increasing soil electrical conductivity,pH,and water-holding capacity.Moreover,concomitantly,we observed a large reduction(99%)in Pb mobility and availability following application of the hardwood biochar in combination with compost(HBCP).Thus,this combined soil amendment was most effective in promoting A.altissima growth.In addition,the HBCP treatment prevented As translocation in the upper parts of plants,although soil pore water As concentration was not diminished by amendment application. | Ibrahim ALIDOU-ARZIKA Manhattan LEBRUN Florie MIARD Romain NANDILLON Gulriz BAYCU Sylvain BOURGERIE Domenico MORABITO | 2021 | Pedosphere2021，31，6： | 0 |
