主动采样技术在中国大气POPs监测中的应用

为了履行斯德哥尔摩公约,查明持久性有机污染物(POPs)在中国大气环境介质的存在水平,该研究首次采用主动采样技术,在中国境内大尺度范围内进行了环境大气中POPs的监测工作.利用主动采样技术,可以在短时间内采集数百立方米的大气样品.分别利用玻璃纤维滤膜采集大气颗粒物(固相)中的POPs,同时使用聚氨酯泡沫(PUF)吸附气态的POPs.该采样技术还便于样品的运输和保存.研究表明,大气主动采样技术可以很好地运用于区域大气POPs的监测工作并填补了我国在POPs履约监测中专用仪器设备的空白.     

Legal aspects of pesticides and toxic substances testing requirements

Abstract

The United States Environmental Protection Agency administers several laws and progrms through which it reviews the hazard potential of pesticides and other toxic substances which may present a risk to human health or the environment. The Agency's ability to assess hazard as required by law depends in part on test data developed through testing standards in Agency regulations. In reviewing the Agency's actions in this regard, the courts emphasize the importance of reasoned regulatory decisions. The legal requirements to assess risk and provide reasoned decisions in this regard establish the legal importance of testing guidelines and test data, and indicate that sound test methodology is as important legally as it is scientifically.     

Safety testing of pesticides and methods of evaluating human exposure in the field

Abstract

The importance of field surveys to provide data on acute pesticide hazards is discussed. The types of questions which small field surveys of pesticide exposure should answer are presented. In addition to protective clothing, the value of distance, time, and personal hygiene in reducing exposure are considered. Finally, the importance of an adequate data base for the development of protocols and guidelines for public protection is discussed.     

A framework for assessing discretionary corporate performance towards the environment

This article reviews the existing models of corporate social responsiveness and develops a theoretical framework with which to examine corporations' discretionary performance with respect to one social issue, that of the environment. Discretionary indicators of corporate response to environmental issues are developed and tested within this framework. Twelve companies from five different sectors were selected for the survey, based on prior knowledge of their commitment to environmental concerns. Primary data was collected from personal interviews, and secondary data was obtained from company documents, annual reports, and other forms of publically disclosed information. Empirical results varied, but certain voluntary indicators, such as composition of the board of directors, the environmental affairs function, community support, and the annual report are considered to provide strong indications of discretionary corporate performance. Philanthropy and company products proved to be less satisfactory indicators of corporate commitment to the environment. The aggregated results revealed a correlation between the final rankings of firms' discretionary environmental performance and whether those companies are process or product oriented. Linkages between discretionary elements and those of economic and legal requirements were not explored.

Opencasting — putting the environment at risk?

Opencast coalmining has been undertaken in Britain since 1942, but national policy towards its role in the energy market has fluctuated, and today there is a growing awareness of its detrimental impact on the environment. This paper explores the changing policy background since 1974 and, through an examination of recent planning appeal decisions, assesses the weight placed on the competing factors underlying the present formulation of government policy. It is submitted that at present government has failed to formulate a coherent policy in terms of land‐use and that the cost of this failure is a continued erosion of the environment.     

走出环境污染的怪圈——就环境论环境不能解决环境问题

历史的经验告诉我们，就环境论环境不能解决环境问题。本文从分析当今时代的特点出发，剖析了我国环境污染形势，最后论述如何走出环境污染的怪圈．经济增长不等于经济发展，但可持续发展却是永恒的主题．解决环境问题必须改变传统发展战略，发展是硬道理，但我们讲的发展是全社会的持续、协调、全面发展。解振华局长说：“工业污染是环境污染的主要来源”。经济增长的源泉在企业，经济增长的动力是企业利益，经济增长的压力是市场的竞争，经济增长的持续是协调发展。只顾产值不讲效益的观念必须改变，环境问题的解决必须和国家的经济发展、科学技术、社会稳定统一考虑，必须纳入国家整体战略，环境问题才能进步解决。
