Research in the environmental chemistry group focuses on the fate and behaviour of contaminants in the environment including human exposure to contaminants. Our projects are interdisciplinary and collaborative. Current projects include determining the effects of environmental stressors and contaminants on production of cyanotoxins in Canterbury waterways, investigating the effects of co-contamination of copper on pesticide degradation in soil and the presence of endocrine disrupting compounds in Antarctic waters and animals.
