Dissolved organic carbon quality influences metal toxicity in freshwaters
This project aimed to characterise the types of dissolved organic carbon found within Australian freshwaters and investigate how these influence metal toxicity to organisms. Dissolved organic carbon has the ability to decrease the toxicity of metals to organisms in natural waters and the intensity of the decrease is related to the type of dissolved organic carbon. Information regarding the types of dissolved organic carbon commonly found within Australian waters is lacking and their impact on metal toxicity to Australian biota is unknown.
This project characterised dissolved organic carbon from different Australian ecoregions and investigated the influence of different types of dissolved organic carbons on metal toxicity. The goal was to incorporate data on dissolved organic carbon quality into predictive models to improve their performance.
