The movement of copper, chromium and arsenic originating from samples of the wood preservative Tanalith® through mildly acidic, sandy loam soil was investigated. Small, undisturbed soil cores (of dimensions 15 × 15 × 15 cm) were removed from the topsoil of a paddock adjacent to the Glenelg River in the Western District of Victoria, Australia. The paddock soils were thin (<30cm) greyish brown, mildly acidic, sandy loams with a moderate organic carbon content (2–5%) overlying a limestone cap. Tanalith® was applied to the surface of the cores which were then irrigated with deionised water at approximately 30 mm day‐1. Copper concentrations in all leachate remained at background levels throughout the experiment, and this element was found to be immobilised in the top 4 cm of the soil. Up to 29% of the applied dose of chromium was detected in the leachate, with breakthrough occurring within 20 days of Tanalith® application. Up to 13% ofthe applied dose ofarsenic was detected in the leachate, although in this case breakthrough was not observed until 25 days after Tanalith® application and leachate concentrations were still rising when the experiment came to a close. Significant concentrations of arsenic and chromium were found in the top 6 cm of the soil profile. 相似文献

Dithianon formulations are unstable in slightly basic aqueous solutions (pH 9, 20°C, t ½ = 5.6 h) but relatively stable in neutral or acidic solution (pH 4,20°C, t ½ = 6443 h). To ensure the efficacy of this fungicide it is important to prepare the spray mix fresh with neutral or slightly acidic water. Dithianon is unstable towards natural sunlight in the solid and aqueous phase, with half‐lives of approximately 68 and 42 days, respectively. Thermal hydrolysis does not seem to be the preferred degradation pathway when aqueous solutions are heated by the South Australian summer sun. The major aqueous phase photodegradation product has been identified as 2,3‐dihydro‐1,4‐dithiaanthraquinone. These results strongly suggest that should dithianon be accidentally released into basic Australian waters then it is likely to be rapidly chemically hydrolysed and pose little long term environmental threat. However, dithianon is only slowly chemically and photo‐lytically hydrolysed in neutral and acidic waters, and in this case accidentally release may pose a significant short term environmental threat. 相似文献

Fleet, work-related or occupational road safety has the potential to make a major contribution to reducing both human harm and asset damage. To date, however, there would appear to be a dearth of well researched and evaluated case studies in the public domain in this area.This paper provides an on-going, documented, real-world case study of work-related road safety within an Australian company that has sought to manage, monitor and improve its road safety performance over the last 5 years through a range of proactive, fleet manager, insurance and risk-led initiatives.Roche Australia has successfully implemented a Company Motor Vehicle Safety Program with support from its fleet insurers and risk management advisors. Four key initiatives are set out covering: (1) Driver risk assessment, monitoring and improvement. (2) Policy development and communications. (3) Process and outcomes evaluation. (4) Continuous review and refinement of policies, processes, programs and future developments.The program has led to a range of process and performance-based outcomes. Typical barriers to success in work-related road safety have been identified and overcome. Almost 100% risk assessment and improvement process compliance by drivers has been achieved. A predictive relationship between risk assessment outcomes and collision history has been identified. Reductions in insurance claims, collision costs and claims ratio have been sustained. A detailed project plan is in place to continue the program for the next 3 years.The paper concludes that with effective management, a well developed work-related road safety program can result in performance improvements within the initiating organisation. Several limitations in the case study methodology, as well as areas for further work and lessons for policy makers, researchers and practitioners are also identified. 相似文献

Hybrid life-cycle assessment employing input–output analysis has advantages over conventional methods. In the inventory phase of a hybrid assessment, the data collection and the boundary selection can be tailored by using structural path analysis. This technique was applied to recent Australian data in order to determine environmentally important input paths in terms of energy consumption, land disturbance, water use, and emissions of greenhouse gases, NOx, and SO2, for all Australian industry sectors. Due to the complexity of inter-industrial transactions, up to third-order paths can be top-ranking. The identification of such paths is considerably more labour-intensive in conventional life-cycle assessments. 相似文献

This article explores the expression of three forest value orientations that emerged from an analysis of Australian news media
discourse about the management of Australian native forests from August 1, 1997 through December 31, 2004. Computer-coded
content analysis was used to measure and track the relative importance of commodity, ecological and moral/spiritual/aesthetic
forest value orientations. The number of expressions of these forest value orientations followed major events in forest management
and policy, with peaks corresponding to finalization of Regional Forest Agreements and conflicts over forest management. Over
the time period analyzed, the relative share of commodity value orientation decreased and the shares of the ecological and
moral/spiritual/aesthetic value orientations increased. The shifts in forest value orientations highlight the need for native
forests to be managed for multiple values and the need for continued monitoring of forest values.

The role of relationships between regulators and consultants engaged in environmental impact assessment (EIA) is explored. A Partnering Agreement between Western Australian regulators and consultants gave rise to a survey and interviews with representatives of these EIA practitioners to understand levels of cooperation between them and ways to improve EIA practice locally. A mixture of quantitative and qualitative responses are presented with an emphasis on practitioner comments reproduced in their own words and ‘voice’. The results suggest that while relationships are strained because of staff resources and levels of expertise brought about by a major resource boom in recent years, there is a great desire for cooperation and collaboration. Greater clarification and understanding of each stakeholder's purpose and role in the EIA process along with opportunities for EIA practitioners to interact, communicate and socialise are identified as positive ways forward. The value of establishing the relatively simple Partnering Agreement approach is demonstrated and is put forward as something that practitioners internationally might equally benefit from as a means of improving the effectiveness of EIA practice. 相似文献

/ With over 2500 Australian Landcare groups, 65,000 volunteer members, and considerable evidence of program impact, Landcare is an important example of state-sponsored rural development in a developed nation. The agency-community partnership is a fundamental element of Landcare and getting the partnership right is vital to long-term program success. After reviewing the emergence of Landcare in the state of Victoria, the author reports research from a 1995 survey of Victorian Landcare groups. Survey information highlighted the extent of agency-group contact, the important roles agency staff played in many Landcare groups, and the positive impact of agency contact and government funding upon group activity. Large majorities of groups reported they were satisfied with their relationship with agency staff. However, a majority of groups reported money or materials provided to manage land and water degradation was inadequate. Recently proposed changes to the Landcare program will provide government funding of work on private property and may address this concern. A majority of groups also reported support for leadership and management training was inadequate and respondents emphasized the need to revise program guidelines that limit funding for group coordinators. This information highlighted the importance of articulating a practical model of community participation in Australia and adopting a systematic approach to providing agency support for Landcare groups. Reflecting upon the Landcare experience, the author suggests some of the key elements of a practical model of state-sponsored citizen resource management contributing to rural development.KEY WORDS: Landcare; Australia; Community participation; Rural development; Citizen resource management; Sustainable agriculture 相似文献
