Remediation of two polluted soils from a northern Italian industrial site heavily contaminated with organic contaminants was attempted here by subjecting soils first to addition with an exogenous humic acid (HA), and, then, to an oxidation reaction catalyzed by a water-soluble iron-porphyrin (FeP). An expected decrease of detectable organic pollutants (>50%) was already observed when soils were...
The development of an integrated strategy for the remediation of soil co-contaminated by heavy metals and persistent organic pollutants is a major research priority for the decontamination of soil slated for use in agricultural production. The objective of this study was to develop a bioremediation strategy for fields co-contaminated with cadmium (Cd), dichlorodiphenyltrichloroethane (DDT), and...
phytoremediation of heavy metals is employed as a technological approach for a non-destructive remediation of contaminated soils. one of the most recently studied tree species used in phytoremediation applications are poplars. in this study, the one-year old rooted seedlings of populus nigra l. used to decontaminate hexavalent chromium-contaminated soils. five treatments of cr (vi) supply (were...
Abstract The transformation of mercury (Hg) into the more toxic and bioaccumulative form methylmercury (MeHg) in soils sediments can lead to biomagnification MeHg through food chain, which poses ecological health risks. In last decade, biochar application, an situ remediation technique, has been shown be effective mitigating risks from Hg sediments. However, uncertainties associated with use it...
