Hydrobiology contributed to the NiPERA Workshop on Advances in Risk Assessment Tools with Relevance to Tropical Southeast Asia and Melanesia (SEAM), held in Singapore this week. The workshop was a wrap up of a 5 year research program into nickel bioavailability and ecotoxicity in the SEAM region. Hydrobiology was responsible for collating water, sediment and soil quality data across the region, and Ross Smith presented the summary of that work, as well as what we have learnt about waters in lateritic areas as part of the project and since. We have also been active partners in prioritising test development for fresh and marine waters and marine sediments, and selecting scenarios for developing risk assessment approaches. Ross also chaired the breakout group on communicating the research outcomes. It was a very productive meeting, with some exciting future directions identified by the workshop attendees.
