We are witnessing a growing concern with the global dimension of many environmental issues, reflected in the increase in the number and significance of international environmental organizations. Yet there is no internationally applicable strategy for environmental research which is management oriented. A new type of research policy, which integrates ideas derived from environmental and human ecology, is required in order to deal with cultural and ecological diversity and their interactions as reflected in the ecology of landscapes. The newly defined concept of environmental health is proposed to fill this gap. This concept integrates the latest developments in landscape evolutionary ecology and environmental health, bringing out a conflict between making the environment conducive to human health and increasing the available options for supporting the essential biological and ecological processes of the environment. Lessons derived from the evolution of human environments are used in order to illustrate how health may become un umbrella for developing an environmental research policy, which could also serve as a catalyst for international environmental projects. 相似文献

五氯酚对环境污染及居民健康影响研究 总被引:2,自引:0,他引:2
中国长期以来使用五氯酚纳盐杀灭亡血吸虫的中间宿主──—钉螺.为评价它对环境的污染及居民健康危害,1990-1993年在我省开展了五氯酚环境污染及对居民健康影响研究.在研究区采集环境样品(空气、水体、土壤及底泥、蔬菜、肉、蛋、鱼等)共173份;生物材料(人血、尿)共457份,分析五氯酚浓度.结果在明,在五氯酚使用区,环境中PCP浓度稍高于对照区,而生物材料尿、血中PCP浓度明显高于对照区.全血胆碱脂酶活性用药区明显低于对照区,统计学分析有显著差异(P<0.001),证实了长期低剂量使用可造成环境及生物蓄积. 相似文献

Risk management practices under the current environmental regulations is a long, complex process that considers scientific,
technologic, and management factors to develop various regulatory standards and pollution control measures. Using the mandatory
enforcement approach, sometimes referred to as “command-and-control”, a set of preliminary environmental goals, such as better
air and water qualities, were achieved. However, the information-intensive nature of the risk management process and the lack
of flexibility in conventional regulatory methods to changing economic and technologic realities of the decade has created
interest among risk managers to examine some innovative management approaches. Above all, environmental problems of a global
scale require novel management methods while striving to achieve the desired environmental goals.
As the principal analytical tool in risk management, quantitative risk assessment exerts considerable influence on the risk
management process. Therefore, advances in risk management are closely associated with scientific developments that enhance
the risk assessment process, particularly those efforts aimed at improving human exposure and toxicity assessments. Market
incentives, information dissemination, creative enforcement practices, and interagency and intergovernmental interactions
were identified as the key elements of innovative environmental risk management practices. This paper will present an overview
of the emerging innovative risk management approaches. 相似文献

Recreational impact was measured on eight beaches in Glen Canyon National Recreation Area and 15 beaches in Grand Canyon National Park using permanently located transects and plots. Recreational impact indices included densities of human trash and charcoal and a measure of sand discoloration due to charcoal. Significant increases in the indices occurred on several Glen Canyon beaches over a seven-month period. Sand discoloration became significantly higher over all Glen Canyon beaches during the same time period. All indices were significantly higher in Glen Canyon than on similar Grand Canyon beaches. These differences are probably due to differences in: (a) level of impacts tolerated by the respective management regimes and, (b) in the number of user days among the two National Park Service administrative units. Management alternatives are presented for reversing the present trends of recreational impact on Glen Canyon beaches. 相似文献

Official Dutch food information apparently tries to avoid images but is implicitly shaped by the metaphor that food is fuel.
The image of food as fuel and its accompanying view of the body as a machine are not maximally helpful for integrating two
important human desires: health and pleasure. At the basis of the split between health and pleasure is the traditional mind–body
dichotomy, in which the body is an important source of evil and bodily pleasure is sinful and dangerous. In the search for
alternatives, new metaphors are proposed that integrate mind and body as well as pleasure and health. The relevance of metaphors
for ethics is at least twofold. (1) Moral thought and theory are at least partly shaped by metaphors. In the light of this
growing recognition, the analysis of morality needs innovation. (2) With regard to food, new metaphors, such as slow food,
or the image of enjoyment as an art, enable a new search for morally responsible forms of hedonism, based on more love and
respect for human as well as animal bodies. But new metaphors are specific and selective, just like old ones. I argue that
a search for the best overall metaphor would be misguided, but that more diverse forms of attention to bodily aspects of life,
including experiences related to food, will result in richer vocabularies of the body, the mind, and body–mind relations.
This holds a promise of moral progress. 相似文献

In response to Evelyn Pluhar'sWho Can Be Morally Obligated to Be a Vegetarian? in this journal issue, the author has read all of Pluhar's citations for the accuracy of her claims and had these read by an independent nutritionist. Detailed analysis of Pluhar's argument shows that she attempts to make her case by consistent misappropriation of the findings and conclusions of the studies she cites. Pluhar makes sweeping generalizations from scanty data, ignores causal explanations given by scientists, equates hypothesis with fact, draws false cause conclusions from studies, and in one case claims a conclusion opposite of what the scientist published. Such poor reasoning cannot be the basis of an argument for moral vegetarianism. A broader search of the literature and attention to reviews and textbooks in nutrition shows that each of Pluhar's claims is suspect or incorrect. Pluhar has not undermined my central claims: even if animals have certain rights and well-planned vegetarian diets are safe in complex industrialized societies, these diets cannot be so regarded if the presuppositions of high levels of wealth, education, and medical care do not exist; and, women, children, the aged and some ill persons are at greater risk on restrictive vegan diets. Thus, any duty of moral vegetarianism is not categorical but provisional in nature. 相似文献
