环境风险评价研究综述

论述了环境风险评价研究的有关基本概念以及主要研究内容的发展，指出了风险评价存在的不足，并在此基础上提出一些合理建议。     

The curve of ion exchange ratio(%)-pH of the interaction between suspended particles with Cd(II) in the Yellow River

The curve of ion exchange ratio(%)-pH of the interactionbetween suspended particles with Cd(II) in the Yellow River wasstudied. The effects of lysine on this curve have been alsoinvestigated. The results showed that (1) Cadmium in Cd(OH)+ formin the suspended particles exchanges with the cations.The exchangeratio of Cd2+ is nearly at its greatest value in the range of pH(8.0-8.5) in natural aquatic system; (2) Ion exchange ratiodecreases as the concentration of Cd2+ raises from 8.9×10-6 mol/L to 2x8.9 x 10-6mol/L; (3) At the lysine concentration of 6.8x10-6 mol/L, it can promote the ion exchange ratio; (4) Adsorption of thesuspended particles to cadmium is weaker in seawater and Jin ShaRiver than in the Yellow River.     

Software as a bridge between theory and practice in life cycle assessment

Three mutually dependent elements are required for the application of life cycle assessment: methodology, data and software. Obviously, the design of software is determined by the methodology and the type of data available. Conversely, the development of software dictates the way in which data should be collected and recorded, and improves the theoretical framework, as it forces one to state the principles clearly and unambiguously. The influence of the development of software on both data and methodology is addressed and illustrated by examples, with reference to two key terms: transparency and explicitness. Three types of influence are distinguished: the design of a protocol, the formulation in terms of recipes, and the presentation of data.     

长江中下游海相三叠系膏盐层与铜(金)、铁矿床

长江中下游海相三叠系膏盖层中含有很大比例的大、中型铜（金）、铁、多金属矿床。膏盐层不仅是铜（金）、铁矿床的主要赋矿层位之一，而且是部分成矿金属的矿源层；膏盐层还为燕山期岩浆提供部分钠质、钾质及挥发组分，影响岩浆演化的方向，改变了含矿流体的性质；另外，从岩体和矿床中金属硫化物中流同位素重硫成分的增高，说明在成者、成矿过程中，膏盐层是硫的供应者之一。因此膏盐层与铜（金）、铁、多金属矿床之间存在着特殊的成因联系。     

城市工业小区噪声现状评价与防治对策研究

对上海工业街坊固定和流动噪声的主要变化和声源强度进行调查和测试，应用ＰＮＩ噪声指数和等级评价方法对该城市工业记噪声进行评价。用数学方法对典型小区和大部分工业街坊的职工和居民的职业病和健康进行分析，并提出减少噪声伤害的若干对策。     

环境影响评价中的"风险评价"实例

环境风险评价在当今环境影响评价中逐渐引起重视，通过对年产30万t磷酸及年产60万t磷铵项目中设计的磷石膏渣场进行的风险评价实例，运用风险评价方法进行了事故分析，并预测了事故发生的风险及后果，提出减缓措施，为项目安全运行提供一定理论依据，同时可为类似项目的风险评价提供参考。

生态技术创新政府启动模式的机理与启示

生态技术创新是经济可持续发展的必要条件。由于环境资源的公共性，时滞性等特点，政府在生态技术创新过程中发挥重要的作用，是企业生态技术创新的主要推动力。政府启动模式的本 于政府借助法律或经济手段促使企业部分边际外部费用内部化。
