Biography

Dr Brad Angel has over sixteen years of experience in the areas of Environmental Chemistry and Ecotoxicology within the Environmental Contaminant and Mitigation Biotechnology Program of the CSIRO Land and Water Business Unit. Research activities include investigating the factors that affect the transport, fate and toxicity of contaminants in aquatic systems. He is an expert in ultratrace contaminant surveys, investigative studies of parameters controlling contaminant release and attenuation, and ecotoxicological testing to assess the effects of contaminant exposure to aquatic organisms (microalgae and invertebrates). External earnings consultancy work has involved many projects for mining and resource companies assisting them with measurement of their environmental footprint and optimisation of on-site processes.
His research and consultancy work is currently delivered through the Land and Water, the Oceans and Atmosphere, and the Minerals and Resources Business Units.
Research topics of special interest have included:
• Improved framework for the regulation of fluctuating metal exposures to aquatic organisms
• Measurement of geogenic contaminant release into produced and flow-back waters from coal seam gas operations
• Ultratrace study of Torres Strait waters to investigate factors affecting spatial and temporal metal variability
• Derivation of an improved water guideline quality for aluminium in marine waters
• Geochemical factors affecting metal concentrations and toxicity in marine waters
• Factors affecting metal release and attenuation in different fresh and marine water systems
• Studying the influence of acid sulfate soils on metal release, bioavailability, and dilution in the Murray River
• Factors affecting the transport, fate and toxicity of metal nanoparticles in aquatic systems
• The effects of deep-sea tailings disposal on metal contamination
• How copper accumulation (during exposure) and elimination (after exposure) effects the toxicity of marine microalgae
• Improved procedures for spiked sediment preparation for whole-sediment toxicity testing.
