Research interests

Bill Langston is head of the ecotoxicology laboratory at the MBA, investigating the behaviour and effects of contaminants (metals, metalloids, organometals, radionuclides and persistent organics). Research encompasses fundamental and strategic studies into the impact of human activities and waste inputs in aquatic ecosystems. Specific themes include: Partitioning, bioavailability and impact of sediment-bound chemicals; Bioaccumulation pathways, processes and models; Metabolism and detoxification of pollutants; Use of biomarkers to measure the health of the estuarine and marine environment.

Current prominence is given to the study of nanoparticle (NP) impacts -investigating sublethal effects in microalgae, crustacea and mollusca in relation to structure and activity of NP. Development of protocols to characterize NP interaction with cell membranes, biochemical systems and links to higher order responses such as growth, development and survival are a major goal. Ongoing projects also include: Endocrine disrupting effects in molluscs in response to oestrogenic and anti-androgenic chemicals; Impact and recovery of benthic ecosystems from organotin (TBT) contamination and other long-term pollution scenarios; Relative importance of biological, physical and chemical processes on the transport and speciation of pollutants; Distinguishing natural and anthropogenic metals; Application of biological-effects tools to assist in monitoring.  Results of this research help to inform UK policy on environmental pollution.
