Bioavailability of hydrophobic organic contaminants in soils: fundamental concepts and techniques for analysis
Soils represent a major sink for organic xenobiotic contaminants in the environment. The degree to which organic chemicals are retained within the soil is controlled by soil properties, such as… Expand
Microbe‐aliphatic hydrocarbon interactions in soil: implications for biodegradation and bioremediation
Aliphatic hydrocarbons make up a substantial portion of organic contamination in the terrestrial environment. However, most studies have focussed on the fate and behaviour of aromatic contaminants in… Expand
Copper speciation and impacts on bacterial biosensors in the pore water of copper-contaminated soils.
Knowledge of heavy metal speciation and its relationship with biological responses is important for the derivation of effects-based soil quality criteria. We determined soluble Cu concentrations an...
Predicting the activity of Cd2+ and Zn2+ in soil pore water from the radio-labile metal fraction
Abstract Cadmium and zinc were added at 3 and 300 mg kg −1 , respectively, to 23 soils and incubated at 16°C and 80% field capacity for 818 d. Following addition of metal, changes in the radio-labile… Expand
Acute toxicity of some treatments commonly used by the salmonid aquaculture industry to Corophium volutator and Hediste diversicolor: Whole sediment bioassay tests
The commercial farming of Atlantic salmon, Salmo salar, typically requires the periodic application of copper-based anti-foulants and chemotherapeutic treatments, including Slice®, Excis®, Salmosan®… Expand
Antimony bioavailability in mine soils.
Five British former mining and smelting sites were investigated and found to have levels of total Sb of up to 700 mg kg(-1), indicating high levels of contamination which could be potentially… Expand

There are strong drivers to increasingly adopt bioremediation as an effective technique for risk reduction of hydrocarbon impacted soils. Researchers often rely solely on chemical data to assess… Expand
Behaviour and assessment of bioavailability of organic contaminants in soil: relevance for risk assessment and remediation
Soils contaminated with organic chemicals are now widespread in industrialized and developing countries, and the risk assessment and remediation of such contaminated sites is a priority. However,… Expand
Application of biological indicators to assess recovery of hydrocarbon impacted soils

Remediation programmes are considered complete when human risk-based criteria are met. These targets are unrelated to the ecological parameters that may be important with regard to future soil uses.… Expand
Assessment of bioavailability of heavy metals using lux modified constructs of Pseudomonas fluorescens
The bioluminescence response of a genetically modified (lux‐marked) bacterium to potentially toxic elements (PTEs) was monitored using an in vitro assay. Washed cells of Pseudomonas fiuorescens were… Expand
