地塞米松生产中毒性物质泄漏的定性定量分析

采用预先危险性分析和事故树分析剖地塞米松生产过程中毒物质产生中毒事故的危险性。指出溴甲烷和氟化氢是典型毒物。同时，利用泄漏和扩散模型定量分析它们泄漏所造成的危险性。结果表明：溴甲烷泄漏时，地面轴线浓度可以达到９２．３ｍｇ／ｍ＾３，远大于其急性中毒阈值，并制定了相应的预防性工程措施。     

城郊道路交通污染个例分析

为建立和研究适合地面道路的宽路幅、高等级、支路多等特点的大城市城郊道路交通大气污染扩散模式,选取了受环境外来源影响较小的上海市沪青平公路的徐泾段,作交通大气污染实测和相关气象因子项目的观测。在获得详细实测结果的基础上,以NOx为例分析了大气稳定度、风向、风速、交通量对城郊地面道路交通污染扩散的影响。     

基于行业全产业链评估一份外卖订单的环境影响

构建"生产-运输-使用-废弃处置"的外卖全产业链，通过大样本企业调研与外卖平台大数据分析，计算8个样本城市不同材质与规格的外卖餐盒、餐具、包装袋的市场使用比例，挖掘骑手配送的海量数据，收集城市垃圾处理处置情况，系统评估外卖全过程的环境影响.结果表明，外卖包装物全产业链中生产环节（45%）与废弃处置环节（50%）为环境影响的主要来源，严重程度依次为固废排放、水污染、资源能源消耗和大气污染.所在城市及选用包装物材质的不同，外卖行业造成的环境影响会有显著区别，全产业链上的各环节需相互配合，多主体共同承担环境责任，采取差别化的减缓应对措施.

Fisheries management: integrating societal preference, decision analysis, and ecological risk assessment

Fisheries management is the practice of analyzing and selecting options to maintain or alter the structure, dynamics, and interaction of habitat, aquatic biota, and man to achieve human goals and objectives. The theory of fisheries management is: managers or decision makers attempt to maximize renewable `output' from an aquatic resource by choosing from among a set of decision options and applying a set of actions that generate an array of outputs. Outputs may be defined as a tangible catch, a fishing experience, an existence value, or anything else produced or supported by renewable aquatic resources. Overall output is always a mix of tangible and intangible elements. However defined, management goals and objectives are essential components of fisheries management or any other field of renewable natural resource management. Reaching consensus on management goals and objectives has never been a simple task. Beyond the broad and often conflicting goals of an agency, managers must decide who should set specific management objectives — agency personnel, the public, or a combination of the two. Historically, rhetoric aside, fisheries managers in North America nearly always have consulted with professionals in governmental roles to set management objectives. In a strongly pluralistic society, this often resulted in protracted political and legal conflict. Increasingly, there are calls for use of risk assessment to help solve such ecological policy and management problems commonly encountered in fisheries management. The basic concepts of ecological risk assessment may be simple, but the jargon and details are not. Risk assessment (and similar analytical tools) is a concept that has evoked strong reactions whenever it has been used. In spite of the difficulties of defining problems and setting management objectives for complex ecological policy questions, use of risk assessment to help solve ecological problems is widely supported. Ecological risk assessment will be most useful (and objective) in political deliberations when the policy debate revolves around largely technical concerns. To the extent that risk assessment forces policy debate and disagreement toward fundamental differences rather than superficial ones, it will be useful in decision making.
