The mismatch of bioaccumulated trace metals (Cu, Pb and Zn) in field and transplanted oysters (Saccostrea glomerata) to ambient surficial sediments and suspended particulate matter in a highly urbanised estuary (Sydney estuary, Australia)
A significant correlation between sedimentary metals, particularly the ‘bio-available’ fraction, and bioaccumulated metal concentrations in the native Sydney rock oyster (Saccostrea glomerata) tissues has been su...

Spatial and Temporal Variance of Metal and Suspended Solids Relationships in Urban Stormwater—Implications for Monitoring
Relationships between total suspended solids (TSS) and metals (Cu, Pb and Zn) were tested and compared amongst base and high flows of three urbanised catchments in Sydney Estuary, Australia. Significant relati...

Modelling nutrient loads to Sydney estuary (Australia)
Sydney estuary (Australia) catchment is substantially urbanised (80%) and small (480 km2) with a large population (2.5 million) and is therefore highly sensitive to anthropogenic influence. The Model for Urban St...
