种子发芽势在环境污染监测中作为生物指标的尝试

本文用测定种子发芽势的方法，对Ｃｄ２＋、Ｈｇ２＋Ａｓ３－的生物毒害效应进行了试验，结果表明，种子发芽指数能很好地反映不同浓度Ｃｄ２＋、Ｈｇ２＋、Ａｓ３－的生物毒害作用．种子发芽势试验也可用于多成分污染物的生物毒性判别，通过相关分析或复回归分析可以大致判别出多成分污染物中何种成分生物毒性大．     

杭州市环境保护投资效益分析

用于环境保护的投资,是防治环境污染,保护和改善生态环境的重要条件。本文从环境保护投资比例、资金流向、治理效果、环境质量改善、环境污染损失,以及城市居民健康变化、环境舒适性和审美学等方面,对杭州市近十年环境保护投资的效益进行了分析。     

试论我国环境行政强制执行制度

环境行政强制执行制度是环境执法的重要制度。大陆法系国家实行德奥模式而从法律上确立环境行政机关强制执行地位，英美法系国家一般实行美法模式而以诉讼方式实现环境行政强制执行，日本则有更为严格、完善的环境行政强制执行制度。比较上述模式后认为：基于我国国情，法律应赋予环境行政机关一定的直接强制执行权，明确环境行政强制执行与司法强制执行的权限，确立环境行政强制执行制度。

Graphical strategies for design of evaporation crystallization networks for environmental wastewater applications

This paper introduces graphical strategies for the design of an evaporation/crystallization network for ternary wastewater environmental applications. Sources, sinks and other streams are located on a ternary composition diagram. While a source is any wastewater stream that has the potential to be recycled, a sink is any unit in the process that can accept sources. The proposed methodology is extremely simple to understand and implement, as it only requires basic solid-liquid phase equilibria data and uses lever arm principles to generate alternative process designs. Geometric constructions are carried out on the ternary composition diagram and the respective lever arms are used to determine intermediate flow rates in the evaporation/crystallization network. The relative locations and flow rates of the sources and sinks under consideration, as well as the unique shape of the solid-liquid equilibrium, drive the design of the separation (via evaporation/crystallization) network. Some generic structures are proposed for a typical evaporation and crystallization network. Once the general problem statement has been defined, special cases consisting of a single source-single sink, single source-two sinks and two sources-single sink are described. These special cases are representative of commonly occurring industrial wastewater design problems. Several graphical insights are listed that allow one to represent evaporation and crystallization operations on a ternary triangular composition diagram and avoid mathematical complexity. The possibility of bypassing a part of the initial feed streams is also considered. Certain feasible composition regions are identified on the ternary composition diagram for cases dealing with multiple sources and sinks. The methodology is useful in pre-screening and eliminating certain sources/sinks and is readily applicable to cases with lower number of sources and sinks. A case study involving the ammonium nitrate manufacturing process is included to demonstrate the broad applicability and value of the proposed approach.

Service transformation—managing a shift from business travel to virtual meetings

It has been shown that the potential for environmental, and financial improvements through the increased substitution of in-person meetings by virtual communication is considerable. However, it has also been shown that this potential is not automatically realized by investing in the technology that can enable virtual meetings. This paper describes two case studies that explored the factors that influenced communication and meeting behavior. A number of drivers and barriers for virtual meetings are identified, and, in addition, measures are proposed to improve the utilization of virtual tools for business communication.
