Overview

Dr Songlin Wu is currently a postdoctoral research fellow, within Environment Centres (CMLR), Sustainable minerals institute (SMI), in the University of Queensland. Songlin graduated with a Bachelor’s Degree in Environmental science (environmental chemistry direction), PhD in ecology (soil remediation and ecological restoration). Songlin's research mainly focuses on 1) plants/microbial driven mineral weathering and transformation, organo-mineral association, and soil structure/aggregate development; 2) Metal(loid) (e.g. cadmium, chromium, arsenic, lead etc) biogeochemistry in plant-microbe-soil system; 3) mycorrhizal fungi & plant interactions and their role in environmental remediation and resilience. I am interested in employing various micro-spectroscopic methodologies to reveal mineral-metal(loid)-organics interactions..

Research Interests

  • Rhizosphere biogeochemistry in soil and mine tailing environments
    My research mainly focuses on 1) plants/microbial driven mineral weathering and transformation, organo-mineral association, and soil structure/aggregate development; 2) Metal(loid) (e.g. cadmium, chromium, arsenic, lead etc) biogeochemistry in plant-microbe-soil system; 3) mycorrhizal fungi & plant interactions and their role in environmental remediation and resilience. I am interested in employing various micro-spectroscopic methodologies to reveal mineral-metal(loid)-organics interactions.

Research Impacts

(1) My PhD study has contributed to the knowledge about the importance of AM fungi in alleviation of metal(loid) phytotoxicity, as well as the underlying mechanisms with focusing on biotranslocation and transformation of metal(loid)s by AM symbiosis. My work showed that ubiquitous rhizosphere microbes such as AM fungi had a great potential in phytoremediation of metal(loid) contaminated soils, and could be used in safe agricultural production or reclamation of metal contaminated sites such as metal mining tailings. My work attracted attention from leading Environmental remediation companies in China and was promoted in Chinese media in the field of environmental remediation, e.g. Ecological Restoration in China (ER‐CHINA), and research agencies such as Chinese Academy of Sciences.

(2) My current research on eco-engineering Fe ore tailings into soil for native plant rehabilitation has revealed the geochemical constraints of Fe ore tailings towards phytostabilization, the key role of eco-engineering inputs (organic matter and pioneer plants) in tailing-soil structure formation, and the underlying geochemical processes and mechanisms. A new conceptual diagram has been formulated to guide further eco-engineering practices on magnetite Fe ore tailings, which attracted the attention of Fe ore mine industry, providing basis for further industry engagement and research collaborations.

Available Projects

  • Sustainable rehabilitation of tailings at metal mine sites is severely constrained by soil resource deficiency. Building on our recent findings of critical processes in soil formation from Cu/Pb-Zn tailings, we aim to develop an integrated technology through eco-engineering the mineralogy and organic constituents of tailings to initiate and accelerate soil formation by using magnetite tailings as a template. The technology will be underpinned by research to mediate and stimulate key biogeochemical and rhizosphere processes in the tailing-soil towards a functional 'technosol'. We aim to apply this technology at metal mines in Australia, to offset the soil required for rehabilitating tailings landforms with native plant communities.
