Amelioration of lead (Pb) from contaminated soil using organic amendments

Assisted attenuation of a soil contaminated by diuron using hydroxypropyl-β-cyclodextrin and organic amendments.

Diuron desorption and mineralisation were studied on an amended and artificially contaminated soil. The amendments used comprised two different composted organic residues i.e., sewage sludge (SS) mixed with pruning wastes, and urban solid residues (USR), and two different solutions (with inorganic salts as the micronutrients and hydroxypropyl-β-cyclodextrin (HPBCD)). After applying micronutrien...

Effects of microbial and phosphate amendments on the bioavailability of lead (Pb) in shooting range soil.

Reduction of chromium toxicity by applying various soil amendments in artificially contaminated soil

Six soil amendments including municipal solid waste compost (MSWC), coal fly ash (CFA), rice husk biochar prepared at 300°C (B300) and 600°C (B600), zerovalent iron (Fe0), and zerovalent manganese (Mn0) were evaluated to determine their ability to reduce mobility of chromium (Cr) in a Cr-spiked soil. The Cr-spiked soil samples were separately incubated with selected amendments at 2 and 5% [weig...

Reducing Heavy Metals Extraction from Contaminated Soils Using Organic and Inorganic Amendments – a Review

Recently problems relating to environmental pollution and the need to protect and preserve the environment from further deterioration has drawn increasing research attention. The goal of any remediation based on soil amendments is to achieve maximum reduction in the bioavailability of heavy metals by immobilization in soils. Modern remediation approaches increasingly focus on in situ environmen...

Copper phytoavailability and uptake by Elsholtzia splendens from contaminated soil as affected by soil amendments.

Pot and field experiments were conducted to evaluate bioavailability of Cu in contaminated paddy soil (PS) and phytoremediation potential by Elsholtzia splendens as affected by soil amendments. The results from pot experiment showed that organic manure (M) applied to the PS not only remarkably raised the H2O exchangeable Cu, which were mainly due to the increased exchangeable and organic fracti...
