Around the world, investment is growing in the electrical economy for communication, transport and renewable energy systems. From smart phones to electric cars, a new generation of High Technology Metals (e.g. gallium, gadolinium & lanthanum) are required, with consequent risks of electronic waste or mine drainage causing coastal pollution. In contrast to copper and other metals widely used historically, there is a lack of knowledge regarding the health impacts of HT metals in marine organisms. Our cause for concern reflects recent evidence for the harmful effects of these metals in freshwater organisms. It is also known that hypoxia and other environmental factors associated with climate change increase the bioavailability and toxicity of metals to marine invertebrates. This exciting project will address urgent knowledge gaps on the interactions between HT metals, hypoxia and other environmental factors and their combined impacts on marine invertebrates.
Laboratory and field experiments will measure bioaccumulation of HT metals in marine crustaceans and molluscs, together with laboratory exposures to metals and hypoxia. Amphipods and molluscs will be of primary interest as their different respiratory physiology may lead to important differences in biological responses of HT metals under the influence of hypoxia. Additional experimental work with our neighbouring industry partner will focus on mysids since they represent key species in marine food webs and are widely used for marine risk assessment. Biological response measurements will include molecular, physiological and reproductive health parameters, optimised for each organism. These data will be integrated with population modelling using the globally important OECD Adverse Outcome Pathway framework for decision making and environmental protection.
The student will join a vibrant research team of international recognized scientists at the forefront of marine conservation. Training will be provided in the marine invertebrate biology, analytical chemistry, molecular biology, physiological techniques, population modelling and quantitative risk assessment.
Applicants should have a minimum 2.1 BSc degree in Marine Biology or an equivalent academic qualification including some experience of marine science. The successful applicant will have excellent skills in data analysis and science communication, together with an aptitude for practical work.
