Pesticide Impact Rating Index – A Pesticide Risk Indicator for Water Quality

Pesticide users, natural resource managers, regulators, government agencies and many others are concerned about the off-site impact of pesticides on the environment. Systematic methods of the assessment of potential risk of pesticides to environmental components can serve as valuable tools in decision making and policy formulation. Simple risk indicators have been developed which cover a range of scenarios such as toxicity to organisms, health of farm workers, consumer health, and residues in harvested produce. The authors have developed a software package named Pesticide Impact Rating Index (PIRI) that outputs an improved pesticide risk indicator for water quality. PIRI is a standalone, user-friendly, platform-independent program. It can be used to (i) rank pesticides in terms of their relative pollution potential to groundwater or surface water, and (ii) to compare different land uses in a catchment or at a regional scale in terms of their relative impact on water quality. It is based on pesticides use; the pathway through which the pesticides are released to the water resources (drift, runoff, erosion, leaching) and the value of the water resources threatened. Each component is quantified using pesticide characteristics (including toxicity to organisms at different trophic levels, i.e. fish, daphnia, algae, etc.), environmental and site conditions (e.g. organic carbon content of soil, water input, slope of land, soil loss, recharge rate, depth of water table, etc.). This paper describes two case studies of the application of PIRI in Australia. The comparison of the risk assessment by PIRI on these revealed that PIRI correctly estimated the pollution potential of pesticides in greater than 80% of cases. A GIS version of PIRI is described in a companion paper in this volume. An erratum to this article is available at .

企业可持续发展评价指标体系的选定原则及构建框架

为了制定企业可持续发展的战略决策,须制定可持续发展的指标体系,并依据这一体系对数据和资料进行收集、整理和分析,从而确定可靠而有效的政策方针。文中论述了可持续发展指标体系的定义、选定标准、原则和可持续发展的评价指标体系,提出了压力-状态-响应框架模型以及不同层次的指标体系框架。该指标体系分为总体层、系统层、状态层、变量层和要素层五个等级。对于持续发展的表征指标及对目前发展的可持续性评估,还需要长时间和切合实际的探讨。     

Non-native Species <Emphasis Type="Italic">DO</Emphasis> Threaten the Natural Environment!

Sagoff [Journal of Agricultural and Environmental Ethics 18 (2005), 215–236] argues, against growing empirical evidence, that major environmental impacts of non-native species are unproven. However, many such impacts, including extinctions of both island and continental species, have both been demonstrated and judged by the public to be harmful. Although more public attention has been focused on non-native animals than non-native plants, the latter more often cause ecosystem-wide impacts. Increased regulation of introduction of non-native species is, therefore, warranted, and, contra Sagoff’s assertions, invasion biologists have recently developed methods that greatly aid prediction of which introduced species will harm the environment and thus enable more efficient regulation. The fact that introduced species may increase local biodiversity in certain instances has not been shown to result in desired changes in ecosystem function. In other locales, they decrease biodiversity, as they do globally.     

铁路客运站疏散安全风险分析与对策研究——以乌鲁木齐站为例

本文对乌鲁木齐站疏散安全进行分析研究。经乌鲁木齐站客流数据分析得,日均客流量1.78万人,日常高峰时段客流量2.4万人,每日早高峰客流在9:00～12:00之间,晚间客流高峰在18:00～24:00之间。乌鲁木齐站以原有疏散能力计算,日常高峰时段旅客平均排队时间为36.7min,其他特殊时段旅客积压排队现象更长,造成旅客需要提前1.3～2.0小时排队进站。影响乌鲁木齐站疏散安全的主要原因包括疏散设施未全部投入使用,安检设备通过能力有限,旅客疏散路线复杂等。笔者从疏散路径、疏散设施和疏散管理等方面提出疏散安全风险控制的对策和建议。

基于突发事件机理分析的风险评估方法研究及应用

近年来,我国部分城市开展了城市安全风险评估工作。为了能够得到科学的风险评估方法和有效的结果,本文基于突发事件机理分析及单一事件链,对城市安全风险评估方法进行了研究及应用。通过引入控制因子,构建基于突发事件机理分析的单一事件链模型,并将该模型转化为风险评估工作的指标体系,并将该指标体系在某区城市安全风险评估工作中进行了应用,对该区17种单位或场所,涉及到的18类风险,共计201家企业进行风险级别评估。最终得出该区17种单位或场所中每种单位或场所的整体风险等级,以及重大风险数量的占比情况,为该区提出有针对性的风险管控意见奠定了一定基础,并对本文的局限性和下一步研究方向提出一些看法和意见。
