Ambient Air Quality Monitoring Network Design for Assessing Human Health Impacts from Exposures to Airborne Contaminants

Existing methods of establishing ambientair quality monitoring networks typically evaluateonly parameters related to ambient concentrations ofthe contaminant(s) of interest such as emissionsource characteristics, atmospheric transport anddispersion, secondary reactions, depositioncharacteristics, and local topography. However,adverse health risks from exposures to airbornecontaminants are a function of the contaminant andthe anatomic and physiologic characteristics of theexposed population. Thus, ambient air qualitymonitoring networks designed for the protection ofpublic health or for epidemiological studiesevaluating adverse health impacts from exposures toambient air contaminants should account for bothcontaminant characteristics and human healthparameters. A methodology has been establishedwhich optimizes ambient air quality monitoringnetworks for assessments of adverse human healthimpacts from exposures to airborne contaminants byincorporating human health risk assessmenttechniques. The use of risk assessment techniquesas the basis for designing ambient air qualitymonitoring networks will help to target limitedfinancial and human resources to evaluate humanhealth risks from exposures to airbornecontaminants.     

Obligations to animals are based on rights

Some feminist philosophers criticize the idea of human rights because, they allege, it encapsulates male bias; it is therefore misguided, in their view, to extend moral rights to non-human animals. I argue that the feminist criticism is misguided. Ideas are not biased in favour of men simply because they originate with men, nor are ideas themselves biased in favour of men because men have used them prejudicially. As for the position that women should abandon theories of rights and embrace an ethic that emphasizes care: women who made this choice would not so much liberate themselves from the patriarchy as they would conform to its representation of women as emotional, subjective and irrational. There is, then, no good reason to withhold ascribing rights to non-human animals, based on the criticisms of rights made by some feminists.Some of the material in the discussion of the feminist critique of rights originally appeared in my The Case for Animal Rights: A Decade's Passing inA Quarter Century of Value Inquiry: Presidential Addresses of the American Society of Value Inquiry, edited by Richard T. Hull, pp. 451–455. Amsterdam and Atlanta, GA: Rodopi, 1994.

城市人居环境的协调发展度研究——以上海市青浦区为例

城市人居环境的可持续发展体系是一个由人口、社会、资源、环境与经济5个子系统构成的开放巨系统。通过提出综合衡量系统“协调性”和“发展水平”的“协调发展度”模型，研究人居环境复合系统内5个子系统之间协调发展度情况。并运用灰色预测理论构建GM（1，N）动态模型，预测未来几年各子系统之间协调发展的状况。     

煤中有害元素对环境和人体健康影响的评价参数

煤中有害元素对环境和人体健康影响的较为全面的评价体系一直未建立，环保部门也缺乏系统性评价参数对电厂等在煤煤过程中有害元素排向大气的释放量进行监测估算。本文在查阅大量资料（主要为外文）的基础上，认为评价煤中有害元素对环境和人体健康影响的参数应该包括以下方面的数据C、H、O、N、无机硫，有机硫，有害微量元素的含量，分布规律，赋存状态，迁移转化行为（在燃煤过程中），洁净能力，淋滤力，矿物质，有机化学特征，煤炭学特征，并对煤中有害元素的污染方法进行探讨，如果上述各参数的数据被全面提供，并据此数据作针对性的抑制措施，煤中有害元素对环境和人体健康危害影响必将降低到最小。

植物多酚物质原位钝化污染土壤重金属的研究Ⅱ.对土壤Cu环境行为和生物活性的影响动态

通过室内好气培养和生物盆栽试验研究了缩合类植物多酚L和Y以及 8 羟基喹啉在污染红壤和潮土中的降解动态及其对土壤Cu环境行为的影响 .结果表明植物多酚在两周内降解相对较快 ,而 8 羟基喹啉则难以降解 .与空白相比 ,Cu污染土壤中施用植物多酚后土壤水溶性Cu显著下降 ,钝化Cu的效果次序为 :8 羟基喹啉 >多酚Y >多酚L .随着植物多酚的降解 ,土壤Cu被释出 ,其水溶性Cu浓度与残留在土壤中多酚浓度 (以DOC浓度表示 )呈负相关关系 ,尤其在潮土上更为明显 ,而pH与水溶性Cu没有相关性 .试验还发现 ,钝化剂施用后 ,小麦体内的Cu含量降低 ,因此 ,植物多酚是钝化重金属污染土壤的良好选择

2000年北京大气中SO2浓度削减50%的健康效益—人力资本法实例研究

人力资本法是评估环境污染健康损害价值（或治理污染的健康效益）的常用方法，但在发达国家，它逐渐被隐含价格法等所取代。本文通过实例研究，探讨了人力资本法在我国目前的适用性，研究结果表明，当使用流行病学关于疾病负担的计量方法（ＹＰＬＬ）时，人力资本法在我国有很大的适用性。     

自然·水·人

人类社会向前发展,人向自然界的索取不断增加,对自然的干扰也逐步加剧,致使自然界的承受能力受到影响,人与自然的关系出现紧张。为此,人必须处理好与自然的关系,以免人的生存环境受到威胁。水是自然界的重要因素,和人的生存与人类社会的发展关系密切。由于用水量不断增加和用水不当,一些地区出现水资源危机,人在和水旱灾害进行抗争中,也出现了由于措施不当带来的人为加大灾害的问题。因此,人必须在处理好与自然关系的框架中,认真处理好与水的关系,以保障水资源的永续利用和人类社会的可持续发展。
