垃圾堆肥场堆肥废气环境影响评价分析

垃圾堆肥场的建设将改变目前垃圾任意堆放的局面 ,堆肥产品可用于林业使垃圾得到无害化处理 ,并变废为宝。尽管如此在垃圾堆肥过程中还将释放出有害气体和垃圾渗透液等影响环境质量。针对堆肥所产生的大气污染物进行源强确定、扩散计算 ,分析其影响范围并推算卫生防护距离。     

环境因素对原生动物群落特征的影响

1999年12月至2000年11月,对华中科技大学华瑜池的原生动物群落进行了研究,共检出原生动物125种,其中植鞭毛虫19种,动鞭毛虫28种,纤毛虫64种,肉足虫14种,对原生动物群落结构和功能的研究表明：1）自然条件下,PFU原生动物群落的种类组成数及原生动物群落的群集速度相对稳定;2）自然条件下,PFU原生动物群落结构和功能不受季节变化的影响;3）当PFU原和动物群落受到外界胁迫时,不管这种胁迫来自物化因素或是生物因素,其群落结构和功能都会发生破坏性变化;4）用PFU法进行原生动物群落生态学和毒理学研究,所得的结构参数及功能参数能反映客观状况,具有环境现实意义。

猛进水库水环境问题研究

猛进水库是五家渠地区的主要水源地,也是乌鲁木齐市重要的淡水鱼供应基地.近年来,猛进水库水质呈不断恶化的趋势,水质为劣V类,为此,猛进水库水质恶化问题已经成为各级政府及公众十分关注的问题.本文选用新疆水环境监测中心多年对猛进水库水质监测及调查的资料,对猛进水库水质现状进行分析评价,运用季节性肯达尔(Kendall)检验等方法,分析了猛进水库水质变化趋势及影响猛进水库水质的主要污染源,提出了进一步保护猛进水库水质的建议,为改善其水环境质量提供依据.

无污染农产品对土壤铅环境质量标准要求的变化——个案研究

研究了江苏南通某乡镇土壤铅的污染以及水稻对土壤铅的吸收。结果表明,研究区土壤与稻米铅污染严重。通过盆栽实验建立了水稻对铅的吸收积累及评估模型,提出了符合该地区大米安全生产的土壤铅临界含量值,为土壤铅环境质量标准的研究提供了参考实例。同时结合国内外环境质量标准的对比,提出无污染农产品对土壤铅环境质量标准要求的变化,建议制/修订土壤铅环境质量标准值。土壤环境二级标准值由现行的250～350mg/kg改为80mg/kg。     

2008年我国环境保护投资总体特征分析

立足于环保投资数据库,从投资构成、空间分布和行业分布3个方面对我国环保投资进行综合分析。2008年,全国环保投资增幅持续保持较快增长,环保投资弹性系数为1.9,环保投资增速大大超过经济增速,"三同时"项目成为拉动环保投资的主要驱动力。引入了环保投资平衡度的概念,在此基础上对各地区环保投资的合理性进行了初步分析。重点行业环保投资方面,工业治污设施运行费用远远大于同期固定资产投资,一定程度上说明了应对治污运行费用来源给予充分重视,采取措施确保稳定可靠的资金渠道。     

Mind the gap in SEA: An institutional perspective on why assessment of synergies amongst climate change mitigation, adaptation and other policy areas are missing

This article takes its point of departure in two approaches to integrating climate change into Strategic Environmental Assessment (SEA): Mitigation and adaptation, and in the fact that these, as well as the synergies between them and other policy areas, are needed as part of an integrated assessment and policy response. First, the article makes a review of how positive and negative synergies between a) climate change mitigation and adaptation and b) climate change and other environmental concerns are integrated into Danish SEA practice. Then, the article discusses the implications of not addressing synergies. Finally, the article explores institutional explanations as to why synergies are not addressed in SEA practice. A document analysis of 149 Danish SEA reports shows that only one report comprises the assessment of synergies between mitigation and adaptation, whilst 9,4% of the reports assess the synergies between climate change and other environmental concerns. The consequences of separation are both the risk of trade-offs and missed opportunities for enhancing positive synergies. In order to propose explanations for the lacking integration, the institutional background is analysed and discussed, mainly based on Scott's theory of institutions. The institutional analysis highlights a regulatory element, since the assessment of climate change synergies is underpinned by legislation, but not by guidance. This means that great focus is on normative elements such as the local interpretation of legislation and of climate change mitigation and adaptation. The analysis also focuses on how the fragmentation of the organisation in which climate change and SEA are embedded has bearings on both normative and cultural-cognitive elements. This makes the assessment of synergies challenging. The evidence gathered and presented in the article points to a need for developing the SEA process and methodology in Denmark with the aim to include climate change in the assessments in a more systematic and integrated manner.
