Pomelo peel has been reported as an efficient biosorbent for lead removal from wastewater treatment processes. The current work aimed to examine the amounts of lead desorption from the biosorbent waste in amended soil samples for up to 3 months (10%

Conventional cultivation practices are known to degrade the physical properties of soils. The objective of this study was to measure changes in soil physical conditions following the establishment of permanent pasture (perennial ryegrass/white clover

The aim of this research was to identify and quantify gaps in currents methods and models for predicting the plant availability of selected nutrient and contaminant metals (Cu, Ni, Zn, Cd) in soil. This study investigated relationships between the re

The two dimensional, small-scale, distribution of labile trace metals was investigated in a sandy loam soil historically treated with sewage sludge. After deployment of two DGT (diffusive gradients in thin-films) probes, their 1.8×15 cm windows were

This paper questions whether the presence of biosolids amendment in metal-spiked soils alters the outcome of soil-based assays of metal bioavailability. The effects of biosolids amendment on the efficacies of six soil metal bioavailability assays (to

Few studies have quantified the accuracy of soil metal bioavailability assays using large datasets. A meta-analysis from experiments spanning 6 months to 13 years on 12 soil types, compared bioavailability estimate efficiencies for wheat and ryegrass

The objective of this study was to examine the effect of soil pH on zinc (Zn) sorption and desorption for four surface soils from the Canterbury Plains region of New Zealand. Zinc sorption by the soils, adjusted to different pH values, was measured f

An incubation experiment was carried out to assess the rate of oxidation of Pb shot and subsequent transfer of Pb to the soil under a range of soil pH conditions. Lead shot corrosion was rapid, so that soil solution and fine earth (

Samples of biosolids, spiked with increasing amounts of Cu, Ni or Zn were applied to field plots in a Pinus radiata forest, and the nutrient and metal status of the forest litter and underlying mineral soil was monitored over a period of six years fo

Zinc sorption/desorption phenomena in soils are important in determining the bioavailability of soil Zn to plants. Some soils of the Canterbury Plains, New Zealand are regarded as potentially Zn deficient, however there is little information availabl
