Research in Focus
Dr Dianne Jolley & the environmental marine chemistry team
What are you researching?
Our research investigates the chemical form and biological impacts of contaminants in the marine environment. We aim to develop robust analytical methods to measure the concentration and form of the contaminants in situ (in the environment), and to assess the biological availability (and toxicity) of these contaminants in marine waters and sediments. Current research is focused on the biological effects of metals in sediments and waters, the fate of metals in marine organisms, and understanding the nitrogen cycle in contaminated marine systems. |

Why is it important?
|
Not all contaminants in our environment are toxic. It is the chemical form of the contaminant that influences its potential toxicity to organisms. Our research aims to identify the particular forms of contaminants in the environment, assess their level of toxicity, and determine if they are in areas that can cause adverse effects. This information is important for both industry and environmental protection agencies, as it will assist in the development of guidelines to better protect our aquatic environment. |
What are your latest achievements?
Being part of a team that won the prestigous 2006 Eureka award was exciting. The Eureka Prize recognizes outstanding achievements in Australian science in four categories – research, leadership and innovation, education and science communication. CSIRO scientists Dr Graeme Batley, Dr Stuart Simpson and Dr Jenny Stauber lead the award-winning team, which alongisde our researchers from UOW, include other CSIRO scientists, the NSW Department of Environment and Conservation and the University of Canberra. |

It has been a tremendous opportunity for students to be able to work as part of a committed industry team and for them to experience research outside the university environment. On-going collaboration with the CSIRO’s Land and Water research unit based at ANSTO in Lucas heights, has proven extremely valuable for students.
Who funds your work?
Our research funding comes from a range of generous supporters including CSIRO, Lake Macquarie City Council, AINSE, Department of Environment and Conservation, Port Kembla Copper, and the University of Wollongong.
Who do you collaborate with?
All postgraduate students involved in this research are involved in collaborative teams. Brad Angel (PhD student), Jacqui Levy (PhD student), Dave Strom (PhD student), Brett Thompson (Honours student) and Daniel Ward (Honours student) are co-supervised by research scientists at CSIRO (ANSTO site), Clare Atkinson (PhD student) is co-supervised by Dr Suzanne Smith at ANSTO (Radioanalytical and Chemical Durability Laboratory), and Ann Mills is associated with the Centre for Atmospheric Chemistry at UoW.
What’s the funniest event to happen in the last three years?
I laughed but my students weren't too amused when .....in 2003 I asked all of my postgraduate students and several undergraduate students in chemistry if they were available to help with some sampling for 4 days. Everyone said “no”, presuming it was another trip to muddy mangroves. I found a volunteer from elsewhere and the sampling trip turned out to be a pleasant 4 days on a houseboat, cruising around a coastal lake, enjoying sunrises and sunsets, snorkelling through the crystal waters to collect our samples.
What’s next?
Well, there is still such a long way to go with what we are doing! The ultimate aim is to gain the ability to predict and prevent the toxic effects of contaminants in our aquatic environments.
Ultimately it would be wonderful to have realistic guidelines that protect our environment, conscientious industries with enormous budgets for rehabilitation and restoration, a healthy coastline, happy marine plants and animals, and excessive amounts of healthy seafood to consume with a fine glass of wine!
