ANSTO Environmental Toxicology and Radioecology team; Tom Cresswell (tom.cresswell@ansto.gov.au)
Team members Tom Cresswell, Danielle Hill and Amy MacIntosh travelled to Oslo, Norway in September 2022 to attend the International Conference on Radioecology and Environmental Radioactivity (ICRER). Tom presented an overview of the management of Naturally Occurring Radioactive Material (NORM) during offshore oil and gas infrastructure decommissioning. His presentation highlighted the need for greater collaboration with radioecologists to provide increased certainty to risk assessments for decommissioning. Tom’s attendance at the conference was supported by the 2022 SPERA Malcolm Cooper Memorial Award. Danielle presented results from lab studies examining the bioaccumulation and retention of 134Cs and 85Sr from solution by Australian native tadpoles including the changes to the biodistribution of these radionuclides during metamorphosis. Amy presented the results of her recent paper (see below) on biota dose modelling of NORMs from subsea pipeline scale.

Francesca Gissi recently joined the ANSTO Environment Research Theme group in an ongoing role as a Research Scientist – Geochemistry. Francesca will be continuing work on the Offshore Infrastructure Decommissioning Project, generating data to assess the risk of mercury to marine biota from this source. Francesca will also be working on the Sites and Soils Project generating a greater understanding of the fate of contaminants from legacy waste sites.
ANSTO Graduate Alexandra Boyd has commenced her third rotation as part of the Graduate Program and will spend 50% of her time with our team on the Offshore Infrastructure Decommissioning Project and 50% of her time with the leader of the Australian Centre for Neutron Scattering (ACNS), Dr Jamie Schulz.
Amy has made progress with developing analytical methods to determine Ra, Th, Pb and Po in marine biota tissues with colleagues from ANSTO’s low level radiation monitoring team. Please contact Amy (amy.macintosh@hdr.mq.edu.au) if you would like to discuss these techniques further. Amy was invited to represent ANSTO and Australia (as a Member State of the International Atomic Energy Agency) at the Biennial Forum on NORM Management and Remediation, held in Vienna. She gave a presentation on the research and collaborations from our Offshore Decommissioning team. We hope to participate in future forums and conferences in this space where we can translate our research into decision-making and international binding policy for NORM management.
Amy and Tom were awarded a few days to visit the Australian Synchrotron located in Melbourne. They used the XFM beamline to investigate the radiological components of pipe scale through high-resolution elemental mapping and are gaining new insights into the incorporation of NORMs in barite scale (see below).

Danielle recently returned from South Carolina in the USA, where she completed a six-month field study as part of her Fulbright Scholarship. Danielle was investigating the bioaccumulation of radionuclides and metals by juvenile amphibians in contaminated wetlands downstream of the Savannah River Site (see image). Watch this space for the publication from Danielle’s study!

Opportunities:
The group are keen to collaborate with other SETAC-AU members on novel studies assessing the risk of various forms of mercury and naturally occurring radioactive materials (NORMs) from subsea oil and gas pipelines to marine organisms. The team are having regular discussions with regulators of offshore oil and gas operations in Australia, who urgently need data on the potential effects of chronic exposure to low radiological doses (from NORMs) and mercury to marine organisms, especially benthic organisms. We have a range of projects available for Honours, Masters and PhD projects. Please contact Tom to discuss further.

CSIRO Environment, Lucas Heights, Contaminant Effects and Risk Assessment Team (Lisa Golding lisa.golding@csiro.au)
On 1 December 2022, CSIRO Land and Water business unit amalgamated with CSIRO Ocean and Atmosphere business unit to become the Environment business unit. The science continues as usual and the move will promote more internal collaboration as well as make life easier for external clients to access our expertise from one instead of two business units.
Lisa Golding had a week of fieldwork on Norfolk Island in August to assist the CSIRO groundwater team with collecting surface water and groundwater samples for determining potential inputs of contaminants into the Kingston Bay area. Lisa is also managing the Norfolk Island marine water quality monitoring program to develop site-specific guidelines that will protect the coral reef and marine ecosystem.
The last 6 months have been busy for Jenny Stauber, attending three international workshops (both virtually and face-to-face) now that international travel has resumed. In May, she was involved in a workshop to develop relevance and quality criteria for exposure datasets (CREED). While data quality criteria schemes exist for ecotoxicity data (e.g., ANZG, Klimisch, CRED) there is no current equivalent for exposure data. The outputs from the workshop will be published as 4 papers mid next year.
Jenny was also part of the steering committee organising and attending a SETAC workshop to incorporate climate change into ecological risk assessment in Oslo, Norway in June. The venue was Oscarsborg Fortress on a small island in the fjord just south of Oslo. The trip was only marred by a terrorist shooting one evening 100 m from her hotel in Oslo, and the fact that 10 of 20 participants (including Jenny) caught COVID, and with missed connections, made for a rough 40-h trip home.
Jenny’s trip to Annapolis, Washington DC in August was fortunately much less eventful. She presented at an invited workshop on climate change and risks for the metals industries, as part of her role on the International Metals Associations’ Ecotoxicity Technical Advisory Panel (ETAP). She also gave virtual presentations on her recent project on deep sea mine tailings placement, as part of the State Key Centre for Marine Pollution, City U Hong Kong’s Distinguished Lecture Series and also for EnviSMART, Melbourne in July.
Jenny was also able to celebrate her induction as a fellow into the Australian Academy of Science at an official in-person ceremony at the Shine Dome in Canberra after receiving confirmation of her acceptance in 2020.
Gwil Price, our PhD student who is working on our IZA funded zinc project, moved to Hobart to take up a part-time role with the Australian Antarctic Division. Gwil is currently at Casey Station in Antarctica (for the second time) over summer. See the photo - is this really work?

The FNQ dry season has allowed some time to rest and regroup for the TropWATER team. Work has largely been directed at report writing and preparing for wet season fieldwork across a number of projects throughout north Queensland and the Northern Territory. Shelley and Sarah are working hard organising the upcoming 2023 SETAC-AU Conference that will be held in Townsville next year! Needless to say the social calendar is very well planned out already!
Our PhD student, Maddi McKenzie is continuing her research into the response of the Upside-down jellyfish (Cassiopea sp.) to emerging contaminants. Maddi’s cultures are currently reproducing and providing her with adequate stocks of experimental subjects.
The ecotox team at AIMS is in the throws of coral spawning, so it's all hands on deck for the rest of the summer!

It’s been a great year, coming out of the COVID fog, with full steam ahead for projects. With field work occurring from the Goulburn River to Kyneton and interstate. Deploying passive samplers in challenging environments, bringing Litter Trackers to the Greater Geelong & Surf Coast, investigating point source and diffuse pollution. We have improved process efficiencies in our labs and have successfully supervised both Honours and PhD projects. Our A3P research partnership with Melbourne Water has been reviewed positively this year, with our projects showing research impact for the business. We were successful in receiving funding through the Port Phillip Bay Fund 2021-22 with a collaborative bid between RMIT- AQUEST and Deakin University. The project Establishing a baseline of Bay condition: pollutants and ecological indicators will look at pollutants and eDNA in sediments in Port Phillip Bay starting in early 2023. For more details see: https://www.marineandcoasts.vic.gov.au/grants/port-phillip-bay-fund
Hot off the press: we have had a major piece of pesticide sourcing work for Melbourne accepted for publication. The paper Sourcing urban pesticide pollution using constructed wetlands in Melbourne, Australia assessed associations between landuse, catchment imperviousness and pesticide occurrence in 111 constructed wetlands in Melbourne and informs monitoring programs (ensuring the pollutants present are being sampled for) and directs further research towards relevant pesticides that pose a potential threat to our receiving waters, while identifying major sources which can become the target of management actions.
In 2022 we have had a visiting academic from Southwest University (SWU), Chongqing, China join the group. Associate Professor, Yuanqin Zeng is working on methods to measure tyre and road wear particles and is with us until June 2023. We have also had two Honours Projects filling knowledge gaps in 2022. David Buckles and Hannah Faraone have recently handed in their thesis’ and given their final talks. David’s project “Assessing the toxicity of aluminium to aquatic plants and invertebrates” was based on elevated detection levels (exceeding guideline values) for aluminium in waterways across Melbourne Water’s Long Term Water Quality Monitoring network. The question was posed: Does this mean that the guidelines are too restrictive or that the current concentrations are causing environmental damage? Tests on two invertebrate and one aquatic plant showed that negative effects were detected at significantly higher concentrations than the current guidelines, suggesting that a re-evaluation of the current guideline value is warranted. Hannah’s thesis “The impact of pollution on biofilms, zooplankton, and macroinvertebrate communities in constructed stormwater wetlands (CSW)” addressed the gap in available information on impacts of pollution to macroinvertebrates, zooplankton and biofilms, investigating the relationships between these communities and pollutants in constructed stormwater wetlands. Her research found that these communities all show potential to be effective bioindicators of pollution in CSWs.

Members of the Behavioural Ecology Research Group have been busy working on two ARC-funded projects investigating the impacts pharmaceutical pollution on the behaviour, ecology, and evolution of aquatic organisms. A notable highlight included a six week research stint in Sweden, where Prof Wong and two of his PhD students, Hung Tan and Jack Brand, completed experiments examining the relationship between pharmaceutical exposure, brain size, and behaviour in fish. The Swedish research was carried out in collaboration with Prof Niclas Kolm (Stockholm University) and Prof Tomas Brodin, Dr Jake Martin, and Dr Michael Bertram (Swedish University of Agricultural Sciences) and involved work on guppies that had been selected for large and small brains as part of a long term experimental evolution study at Stockholm University. Towards the tail end of the trip, several other members of the Research Group arrived in Sweden to present their behavioural ecotoxicology work at the 19th International Society for Behavioural Ecology Congress in Stockholm. At the same conference, Prof Wong—in his role as the Chair of the 20th ISBE Congress—made a pitch to conference delegates to promote Melbourne as the host city and venue for the 2024 Congress.
The Behavioural Ecology Research Group has welcomed three new PhD students to the Group. Gabriel Melhado and Jack Manera will be investigating the impacts of psychoactive pollution on wildlife immune responses and cognition, while James Wiles will be looking at the movement of pharmaceutical pollutants through the environment. The Group also celebrated the achievements of two PhD students, Lucinda Aulsebrook and Jack Brand, who both submitted their theses over the past few weeks. More recently, the Research Group got together for their lab Christmas party, which also provided an opportunity to reflect on another successful year.

School of Life and Environmental Sciences, Deakin University – Dr Aaron Schultz (aaron.schultz@deakin.edu.au, @Dr_Nanotox)
There has been alot to celebrate in 2022 in the Schultz lab with the Oilers making it to the 21/22 Conference final in the NHL, the Pies falling agonisingly (1point) short of a grand final appearance against the Cats (2023 will be the Pies year) and the Socceroos progressing to the final 16 and putting up a great fight against Argentina in the World Cup (we won’t mention the cricket). Moving onto more important updates and research, members of the Schultz lab have enjoyed a very productive year doing what Matt Damon did so well in the movie The Martian by “sciencing the s@#t out of this” 2022! In the past 6-months two students successfully completed their PhD’s and so congratulations Dr Ayushi Priyam and Dr Shweta Gehlout. Ayushi and Shweta’s PhD projects investigated the environmental and human toxicity risks of iron-based and phosphorous-based nanofertilisers being developed for agriculture. PhD student Nishat Urmi recently completed her first sampling trip to Lake Colac with her project investigating the spatial and temporal levels of heavy metals and microplastics in the Lake. This is a collaborative project with Dr Ben Long (Federation Uni) and Barwon Water. The Schultz lab is also currently hosting two visiting PhD students, Ms Natasha Yadav and Mr Anurag Nath, from the TERI-Deakin Nanobiotechnology Centre (New Delhi, India). Anurag and Natasha are investigating the uptake and toxicity of a variety of nanomaterials to freshwater planaria. Finally, PhD student Mr Kamal Poudel has been investigating the toxicity risks of micro and nanoplastics to human health, and Mr Samuel Eke recently commenced his PhD and is developing new methods for creating secondary microplastics that can be used in ecotoxicity testing. The group is looking forward to another fun and exciting year in the lab and field in 2023 and we wish everyone reading this a Merry Christmas and Happy New year!
