Supervising Scientist research profiles
Dr Andrew Harford is a Senior Research Scientist and the acting Team Leader of the Water and Sediment Quality (WASQ) team. The WASQ team uses an integrated creek monitoring program to predict and measure the potential impacts from mine-water discharges. This involves the use of field-based biomonitoring tools to assess the impacts of mine-water discharges from the Ranger mine and the derivation of water/sediment quality standards using laboratory toxicity tests and field-based observations. The WASQ team also develops new standardised biological toxicity tests and leading-edge tools for biomonitoring, such as genomics and videography. Andrew also co-manages the Ecological Risk Assessment program, which brings together all the knowledge acquired for the Ranger mine. This knowledge is used to assess the risks of individual stressors, their cumulative risks and identify Key Knowledge Needs. He has also provided his expertise to collaborative projects to help extend the capacity of ecotoxicology and ecological risk assessment for other mines and for tropical marine environments.
