This pilot study was initiated to provide new information on the 'hormonal' activity of Victorian rivers. Chemcatcher™ passive sampler systems containing Empore™ C18FF disks were deployed at eight riverine sites near Melbourne. Little estrogenic activity [<0.4-1.8 ng estradiol equivalents (EQ)/disk] and no retinoic acid activity (RAR, all samples <0.8 ng trans-retinoic acid EQ/disk) was observed. Almost all sample extracts showed aryl hydrocarbon receptor activity (from <4 to 29 ng ß-naphthoflavone EQ/disk). Overall, the disk extracts were eminently compatible with the bioassay screening technology, enabling the relative levels of 'hormonal activity' to be observed in the surface waters in and around Melbourne. From a practical perspective, the in situ sampling and pre-concentration provided by passive sampling reduces the manual handling risks associated with sample transport, and the number of laboratory operations required to obtain assay-ready solutions for analysis.
