An integrated river basin-coast-sea modelling scenario for nitrogen management in coastal waters

Linked river basin and coastal water models were applied to analyse the effects of an optimal nitrogen management scenario in the Oder/Odra river basin on water quality in the Oder (Szczecin) Lagoon and the Pomeranian Bay (Baltic Sea). This scenario would reduce nitrogen loads into the coastal waters by about 35%, a level which is similar to the load of the late 1960’s. During summer the primary production and algae biomass in the Oder estuary is limited by nitrogen, which makes a nitrogen management reasonable. The comparison of the late 1960’s and the mid 1990’s shows that an optimal nitrogen management has positive effects on coastal water quality and algae biomass. However, this realistic nitrogen reduction scenario would not ensure a good coastal water quality according to the European Water Framework Directive. A good water quality in the river will not be sufficient to ensure a good water quality in the lagoon. Nitrogen load reductions bear the risk of increased potentially toxic, blue-green algae blooms, especially in the Baltic coastal sea. However, to reach water quality improvements in lagoons and inner coastal waters, nitrogen cuts are necessary. A mere focus on phosphorus is not sufficient.     

Illegal landfill in Italy (EU)—a multidisciplinary approach

Illegal dumping of solid waste is a matter of recent concern because of its numerous impacts. The regulatory framework of the European Union and Italy is disclosed. Degradation of air, bodies of water, groundwater, and soil can occur in the illegal landfill and surrounding sites causing e.g. acidification, eutrophication global warming and photochemical smog. Animals and plants are subjected to landfill borne pollutants that can damage them seriously. Landfill pollutants have also harmful effects on human beings raising the risk of illness such as cancer and cardiorespiratory disease. Finally illegal landfilling practices lead to economical, aesthetic impacts, and sociological discomfort that lead to multiple collective actions, blockages, and information campaigns, rising sense of belonging.     

金属有机骨架材料UiO-66的制备及其对溶液中NO_3~-的吸附

采用溶剂热法合成了金属有机骨架材料UiO-66。通过XRD、SEM、FTIR对其进行了表征。考察了UiO-66对溶液中NO_3~-的吸附性能。实验结果表明,加入冰乙酸作调节剂后,得到的UiO-66晶体形貌均匀,直径在100nm左右,结晶度更好。在初始溶液pH为5、反应温度为30℃的条件下,UiO-66吸附NO_3~-反应90 min后,吸附达到平衡,平衡吸附量为39.67 mg/g。UiO-66吸附NO_3~-的吸附行为符合Freundlich等温线和准二级动力学吸附模型。吸附作用主要是材料中金属位点Zr对NO_3~-的静电吸附。UiO-66材料具有良好的再生性能,可重复使用。     

From consultation to deliberation? Tracing deliberative norms in EIA frameworks in Swedish roads planning

This paper presents the results of an analysis of deliberative norms in the framework for Environmental Impact Assessment (EIA) in roads planning in Sweden. The more specific question is how this framework has responded to the shift towards more deliberative approaches to planning and decision making, advocated in planning theory and policy literature over the last decade. The analysis, which compares the current framework and guidance with an earlier iteration, identifies a shift towards deliberation; deliberative norms are present, and even dominate recent guidance. However, an instrumental norm permeates both the former and the current guidance, suggesting that even as a language of consultation is replaced by one of deliberation, the intention remains to secure and legitimise a smooth development pathway. Evidence from interviews with professionals working in the Swedish EIA system highlights the difficulties of navigating these uncertainties in practice. By opening up critical analysis of deliberative norms as they shape the conditions for practice, this study contributes to the continuous development of planning practice, by supporting a more normatively reflexive approach to framework-design.     

Genotoxicity at Low Level Dose of Inspirable Urban Ambient Air Particulate in a Semiarid Regime

Samples of inspirable air particulate(inhalable + ingestable) were obtained at two urbanlocations in southern Argentina which differ in theirexposure to pollution by class B2 polynuclear aromatichydrocarbons (PAHs). Sample extracts were tested in vitro for induction of chromosomal aberrations incultured rat hepatocytes. The average induced amountof chromosomal aberrations did not vary amonggeographic locations, but significant differences wereidentified in samples near known emitting sources. Thedifferences were analyzed in the frame of a model ofthe emissions and their subsequent distribution andre-suspension from the soil and other surfaces. Theresults show that the rat hepatocyte test is sensitiveto genotoxic activity of the urban air particulate inthe low dose range of the tested fractions. Adequatemodels of human exposure to these materials shouldconsider emissions and re-suspension of pollutants bywind. The implications of these results on theformulation of policies of emission reduction, urbansoil management and the design of cancer epidemiologystudies are discussed.     

传统给水处理厂氯消毒模型的开发与应用

以建立给水处理过程的风险分析方法为目标,提出了适用于传统给水处理工艺的氯消毒概率机理模型.模型既考虑氯消毒过程中有机物、余氯、氨氮、溴离子之间化学反应,又考虑水厂混凝、沉淀和过滤工艺过程中的物理和生物作用.典型水厂的现场监测数据表明,该模型能够较好地模拟水厂中高锰酸盐指数、氨氮以及4种三卤甲烷的浓度概率分布.Monte Carlo模拟的结果表明,与我国城市供水水质标准相比,该水厂高锰酸盐指数和单种三卤甲烷的超标概率极低,但总三卤甲烷的超标概率略高,约为2.3%.     

Land-use and agriculture in Denmark around year 1900 and the quest for EU Water Framework Directive reference conditions in coastal waters

The EU Water Framework Directive (WFD) aims to protect the ecological status of coastal waters. To establish acceptable boundaries between good and moderate ecological status, the WFD calls for reference conditions practically undisturbed by human impact. For Denmark, the nitrogen (N) concentrations present around year 1900 have been suggested to represent reference conditions. As the N load of coastal waters relates closely to runoff from land, any reduction in load links to agricultural activity. We challenge the current use of historical N balances to establish WFD reference conditions and initiate an alternative approach based on parish-level land-use statistics collected 1896/1900 and N concentrations in root zone percolates from experiments with year 1900-relevant management. This approach may be more widely applicable for landscapes with detailed historic information on agricultural activity. Using this approach, we find an average N concentration in root zone percolates that is close to that of current agriculture. Thus, considering Danish coastal waters to be practically unaffected by human activity around year 1900 remains futile as 75% of the land area was subject to agricultural activity with a substantial potential for N loss to the environment. It appears unlikely that the ecological state of coastal waters around year 1900 may serve as WFD reference condition.

Framework for the environmental impact assessment of operational shipping

Shipping is an important source of pollution affecting both atmospheric and aquatic environments. To allow for efficient mitigation of environmental degradation, it is essential to know the extent of the impacts of shipping in relation to other sources of pollution. Here, we give a perspective on a holistic approach to studies of the environmental impacts of operational shipping through presentation of an assessment framework developed and applied on a case of shipping in the Baltic Sea. Through transfer of knowledge and concepts, previously used in assessments of air pollution, now applied to assessments of marine pollution and underwater noise, the horizon of understanding of shipping-related impacts is significantly improved. It identifies the main areas of environmental degradation caused by shipping and potential improvements through legislation and technological development. However, as the vast majority of contaminants discharged into the sea are not routinely monitored and assessed, the links between pressure of contaminants from shipping and environmental state and impacts will not be caught in the current environmental regulatory frameworks.
