生物反应器填埋场渗滤液及其处理对策

根据垃圾的降解和稳定机理分析了生物反应器填埋场渗滤液的动态变化规律，并对其处理对策进行了探讨。生物反应器填埋场前期产生的渗滤液可全部回灌，后期再根据实际情况排放处理部分过量的渗滤液。在对渗滤液水量和水质全面直观认识后，再对生物反应器填埋场渗滤液处理工艺进行针对性的选择和设计，并宜采用物化法处理方式。     

五日生化需氧量(BOD5)测定方法探讨

本文针对GB／T7488-1987《水质五日生化需氧量(BOD5)稀释与接种法》中BOD5的测定和计算时接种稀释水的空白扣除方法，提出了直接测接种液的BOD5值，按接种液的比例在水样中进行扣除的方法，提高了BOD5值的准确性。更能反应BOD5的真实性。     

数据包络分析(DEA)模型在清洁生产评价中的应用

清洁生产技术方案评价对于指导企业实施清洁生产有重要意义。将污染物产生量数据作为一种输入引入数据包络分析(DEA)模型，利用该模型对清洁生产技术方案中的投入、产出和污染物发生量进行有效性评价。分析不同方案相对效率值、目标改进值，发现最有效的清洁生产技术方案，达到经济效益和环境效益的统一。本研究为企业筛选和决策可实施清洁生产技术方案提供技术理论支持。     

区域环境--经济协调发展定量分析方法研究

本文对目前常用的环境与经济协调发展分析方法的优劣和特点进行了具体分析，指出现在常用的进行可持续发展水平定量分析的层次分析法存在明显的缺陷，以及现有的几种评价环境与经济之间协调程度的方法的局限性。提出了较为客观实用的评估方法，即依据系统分析和数理统计的原理利用主成分分析进行环境——经济协调度分析，并对环境——经济协调度定量评估的步骤、方法包括测算方法的选择、数学模型的建构进行深入的探讨和研究，以南阳市为例对该方法进行了验证。

Genetically Modified (GM) Crops: Precautionary Science and Conflicts of Interests

Risk governance of GM plants and GMfood products is presently subject to heatedscientific and public controversies. Scientistsand representatives of the biotechnologyindustry have dominated debates concerningsafety issues. The public is suspicious withregard to the motives of scientists, companies,and political institutions involved. Thedilemmas posed are nested, embracing valuequestions, scientific uncertainty, andcontextual issues. The obvious lack of data andinsufficient information concerning ecologicaleffects call for application of thePrecautionary Principle (PP). There are,however, divergent opinions among scientistsabout the relevance of putative hazards,definition of potential ``adverse effects,' andwhether actions should be taken to preventharm. The reliance on the concept ofsubstantial equivalence in safety evaluation ofGM food is equally controversial. Consequently,value assumptions embedded in a scientificframework may be a barrier for employment ofthe PP. One of our major conclusions is thatprecautionary GMP usage requires riskassessment criteria yet undeveloped, as well asbroader and more long-term conceptions of risk,uncertainty, and ignorance. Conflicts ofinterest and public participation are otherissues that need to be taken intoconsideration. GMP governance regimes that arejustifiable from a precautionary and ethicalpoint of view must transcend traditionalscientific boundaries to include alternativescientific perspectives as well as publicinvolvement.     

You Are What You Eat: Genetically Modified Foods, Integrity, and Society

Thus far, the moral debateconcerning genetically modified foods (GMF) hasfocused on extrinsic consequentialist questionsabout the health effects, environmental impacts,and economic benefits of such foods. Thisextrinsic approach to the morality of GMF isdependent on unsubstantiated empirical claimsand fails to account for the intrinsic moralvalue of food and food choice and theirconnection to the agent's concept of the goodlife. I develop a set of objections to GMFgrounded in the concept of integrity andmaintain that food and food choice can beintimately connected to the agent's personalintegrity. I argue that due to the constitutionof GMF and the manner in which they areproduced, such foods are incompatible with thefundamental values and integrity of certainindividual moral agents or groups. I identifythree types of integrity that are threatened byGMF: religious, consumer, and integrity basedon certain other moral or metaphysical grounds.I maintain that these types of integrity aresufficiently important to provide justificationfor political and societal actions to protectthe interests of those affected. I conclude byproposing specific steps for handling GMFconsistent with the moral principles ofinformed consent, non-maleficence, and respectfor the integrity of all members of society.They include mandatory labeling of GMF, theimplementation of a system for control andregulations concerning such foods, andguaranteed provision of conventional foods.
