Dr Rick van Dam – BSc (Hons), PhD
Dr Rick van Dam leads the ERISS Ecotoxicology program. He has a background in aquatic toxicology and ecological risk assessment, with experience also in marine and freshwater ecology. He has coordinated and been involved in assessments of a variety of wetland threats, including the impacts of chemical contaminants, invasive species, and climate change and sea level rise. Rick's experience in aquatic toxicology encompasses assessments of both inorganic (mostly through mining activities) and organic (eg pesticides, hydrocarbons) contaminants to aquatic animals and plants. He has also been involved in developing a wetland risk assessment framework for the Ramsar Convention, and its application to both chemical and biological threats.
Areas of expertise and research interests
Aquatic ecotoxicology; ecological risk assessment; derivation of water quality guidelines; monitoring and assessment of contaminant impacts on aquatic ecosystems.
