AbstractThis article describes the applications of X‐ray fluorescence (XRF) as an analytical tool in forensic science, including limitations and practical aspects. The use of XRF is specifically discussed for the forensic analysis of materials of forensic interest such as metals, gunshot residues (GSR), paint, glass, soil, fibers, plastic and general polymers, and miscellaneous types of evidence. Recent developments such as micro XRF and total XRF are also described. These specialized techniques have highly desirable characteristics for the elemental profiling of a wide range of forensic samples, and hence it can be anticipated that they will find increasing use in forensic laboratories in the future.

Detailed investigations have been conducted on a set of four pilot scale subsurface flow (SSF) constructed wetlands in order to characterise heat transfer, mass dispersion and biological performance mechanisms. These studies have followed the beds from post construction through unplanted hydraulic base line studies to the current status of mature stands of Phragmites australis. Experimental observations indicate that in unplanted beds, daily thermal fluctuations are depth dependent and range from 1 to 9 degrees Celsius. These fluctuations result in daily thermal inversions, and enhanced mixing and oxygen transport. For planted beds, thermal fluctuations are depth independent, and have a constant amplitude of 2 degrees Celsius. Planted beds may be thermally stratified. Lithium tracer studies corroborate these results for the planted bed. In addition, performance studies indicate that organic pollutant removal is probably limited to organic suspended solids removal, with subsequent biological breakdown. Current first-order plug flow models can not account for these operational issues. A combined model is necessary to account for lateral dispersion, temperature gradients and settling of suspended solids to accurately reflect real biological removal mechanisms

Abstract Common plastic drug packaging material available in Australia and in Asia was analyzed using a standard protocol including optical examination, UV-visible and Fourier transform infrared spectrometry. The aims were to determine whether there are significant differences between different sources, to establish the evidential value of these examinations, and to build a database of common packaging material. Visual examination was the most effective means for discriminating samples. Thickness and weight measurements provided useful information. Visualization of machining marks using crossed polarized light was found to be useful in the comparison process. UV-visible spectrophotometry has some value for distinguishing samples. Fourier transform infrared analysis was a good technique for determination of the polymer composition of the packaging. Significant differences were observed between Australian and overseas samples. The “Australian Database of Drug Packaging Materials” was created to systematically collate all of the collected data for application on personal computers. It is concluded that the properties of plastic packaging materials can be excellent indicators for identifying the specific brand or origin of the packaging.

Abstract The ability of 1,2-indanedione and 5,6-dimethoxy-1,2-indanedione to detect latent prints on porous surfaces, as compared to DFO and ninhydrin, has been evaluated. Comparisons of prints developed under various conditions determined the optimum development conditions for the new reagents. The indanediones tested were found to have lower detection limits for glycine. The carrier solvent used was found to affect the quality of the prints developed. In Arklone, the new reagents developed prints that displayed superior luminescence to those developed with DFO. In HFE 7100, 1,2-indanedione and 5,6-dimethoxy-1,2-indanedione gave superior luminescence to DFO after zinc salt treatment and cooling with liquid nitrogen, both of which improve the luminescence of prints developed with 1,2-indanediones, 1,2-Indanediones could offer less expensive but effective alternatives to DFO. With further optimization, the new reagents may supersede DFO as the method of choice for the detection of latent fingerprints on porous surfaces.

Currently the accepted practice for swine wastewater disposal is lagoon stabilisation followed by land application. This disposal method can exacerbate odour emissions and contribute to soil contamination and eutrophication of waterways. Intensification of the pig industry has increased the impact of individual piggeries; this combined with tightening legislation is causing the pig industry in Australia to look at alternative treatment methods. A pilot scale sequencing batch reactor (SBR) was built to treat piggery wastewater. It achieved NH4+ and odour reductions of greater than 99% as well as 79% removal of COD and a 49% reduction of PO43-on a mass balance basis. The reactor experienced problems with foaming for the first 2 months of operation, which was controlled with vegetable oil until the foaming stopped. Struvite formation also occurred within the reactor and influent pipes but it was calculated that sufficient nutrients were removed to prevent precipitation down stream of the SBR.
