Redbank Mine fish toxicity assessment
NT Department of Mines and Energy
We collected fish, water and sediment samples from creeks in the Northern Territory to determine the extent of heavy metal contamination downstream of a disused mine.
Following consultation with Traditional Owners to determine which species were eaten and how they were prepared, fish were collected and their flesh analysed for concentrations of heavy metals. Water and sediment samples from the same sites were also sent for analysis. Results of the flesh analyses were compared to human health guidelines to develop safe consumption levels. The project is being led by Eco Logical Australia in collaboration with Charles Darwin University, the Northern Territory Government, toxicology experts, and the indigenous community of Borroloola and surrounding area.
