N1 - Funding Information:
3D modelling with VRML at Geoscience Australia was pioneered by Russell Hay and Malcolm Nicoll. The models currently available on the OzEstuaries Website were created by James Coffey, David Ryan, Dale McNally, Helen Bostock, Benjamin Hardy and David Beard. The authors greatly appreciate the editorial support provided by John Creasey, Brendan Brooke, Lynda Radke and Fiona Watford. This study was partly funded by the Cooperative Research Centre for Coastal Zone, Estuary and Waterway Management and Geoscience Australia as part of the Coastal Water Habitat Mapping (CWHM) and Fitzroy Agricultural Contaminants (AC) Projects. Published with permission of the Executive Director, Geoscience Australia.

N2 - Electrochemical removals of natural and synthetic estrogens, Estrone (E1), 17β-Estradiol (E2) and Ethynylestradiol (EE2), were experimentally studied using granular electrolytic reactor in combination with a cyclic voltammetric technique. Experimental results showed that by an application of electric current, the estrogens were oxidized at 600-800 mV (vs. Ag/AgCl reference electrode) on the surface of anode and then removed through polymerization of estrogens. Moreover, the electrochemical removal of the estrogens could be reasonably well simulated by a mathematical model developed assuming the external liquid-film mass transfer as a rate-limiting step. Furthermore, it was found that E1 was produced and then removed during the treatment of E2. Further study will be needed to quantify and control the electro-polymerization of estrogens.
