Development of a passive sampler device for polar pesticides (July 2006)
Hyne, R Aistrope, M
This RIRDC report presents the results of the Development of a passive sampler device for polar pesticides project. The projects aim was to develop a passive sampling device that could accumulate more water soluble or polar pesticides during an in situ deployment and that allowed the pesticides to be quantified after retrieval of the device. Two passive sampler devices were constructed of either a low-density polyethylene or cellulose membrane bag (40 μm thickness) containing a mixture of the solvents 1-dodecanol and 2,2,4- trimethylpentane as the sequestering medium. The cellulose membranes were pre-stained with ruthenium red for 96 hours to inhibit cellulose degradation. The study was undertaken using a laboratory flow through system and full field studies. The report concluded that the project validated, easily applied and relatively low-cost method provides a convenient reference system by which improvements in water quality can be assessed.
