Taking into account current environmental concerns, the main objective of this work focused a national inventory aiming to estimate the amount of polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/PCDF) released in Portugal in 2006. The methodology used was based on the Standardized Toolkit for Identification and Quantification of Dioxins and Furan Releases, developed by UNEP Chemicals, in 2005. The method allows the assessment of the amount of PCDD/PCDF released into the environment along five vectors involving air, water, land, products and residues. Facing some difficulties mainly regarding to the availability of data for some activities known to produce PCDD/PCDF, three scenarios (Sc1 to Sc3) corresponding to lower, central and upper estimates were established. The Sc1 scenario (lower estimate) includes the situations where in case of doubt or scarce information, reduced or none emission values were assumed, Sc2 refers to a central estimate, which is believed to be the most realistic for the Portuguese situation, while Sc3 corresponds to the worst case (upper estimate). The results obtained pointed out that the total amount of PCDD/PCDF emitted in Portugal during the period under analysis was in the range of 51.2-217.9 g TEQ year−1, with the most likely value of 95.2 g TEQ year−1 achieved under the Sc2 scenario. This study also showed that the methodology developed by UNEP Chemicals is a very simple one, and the main difficulty is the availability of data. The main indicators calculated in this study were 8.98 μg TEQ/(year person) by taking into account the total amount of PCDD/PCDF released, and 3.63 μg TEQ/(year person) when only air emissions were considered.  相似文献

From a state-centric view, sub-national level of participation at the international level can be only feasible if it is an active part of national policy. In the case of Shiga prefectural government's initiative for international lake-environmental cooperation, however, sub-national actors came to see themselves as direct players in the absence of national policy. This study examines under what conditions and in what ways such sub-national level of participation takes place by conducting a case study of Shiga's collaboration with the United Nations Environmental Programme (UNEP) over lake-environment risk reduction. The article finds that the process of Shiga's participation in transnational governance will have less chance of being duplicated effectively in other Japanese sub-national governments. Shiga's cooperation with the UNEP was primarily driven by the ad hoc bottom-up political mobilisation of the sub-national actors. In general, without institutionalised channels for sub-national governments to participate in the regional/international level, sub-national governments need to mobilise resources on such an ad hoc basis and only pioneering sub-national actors are capable of effectively engaged on unfamiliar territory with the formation process of transnational governance.  相似文献

Zusammenfassung  UNEP International Register of Potentially Toxic Chemicals (IRPTC) wurde von der ersten VN-Umweltkonferenz 1972 geschaffen. Sein Einfu? und Zusammenwirken in den 80ziger Jahren mit anderen internationalen Programmen der WHO, FAO, OECD und EG in der Chemikalienkontrolle wird beschrieben. Nach dem Erdgipfel von Rio 1992 werden im VN-Rahmen drei neue Gremien gebildet, die das Fachprogramm des Kapitels 19 der Agenda 21 (umweltfreundliches Chemikalienmanagement) umsetzen sollen: die United nations Commission of Sustainable Development, das Intergovernmental Forum on Chemical Safety und das Interorganization Programme for the Sound Management of Chemicals. Der Erdgipfel brachte auch für IRPTC eine Neuorientierung. Seit 1996 hat UNEP Chemicals, wie sich IRPTC nunmehr nennt, drei Aufgaben in sein Arbeitsprogramm aufgenommen, die beschrieben werden: das internationale übereinkommen zum Prior Informed Consent, das internationale übereinkommen zur Kontrolle der Persistent Organic Pollutants, und schlie?lich sein traditionelles Arbeitsgebiet des Informations-austausches über Stoffe wird weitergeführt.
Die Aussagen dieses Beitrages sind die Meinung des Autors. Sie müssen nicht mit der Auffassung des Umweitbundesamtes oder von UNEP Chemicals übereinstimmen.  相似文献

The present paper summarises the results of the project: 'Survey of Anthropogenic Sources of Dioxins and Furans in the Baltic Region'. As a part of the project, inventories have been carried out in Estonia, Latvia, Lithuania and Poland by applying the toolkit for quantification of dioxin and furan releases developed by UNEP Chemicals. The main route of direct releases to the environment is emission to air. Total emission to air from Poland was estimated at 490 (88-1,300) g I-TEQ/year, whereas the emissions from Estonia, Latvia and Lithuania were estimated as being 14 (2.4-54), 23 (2.6-63) and 17 (2.6-38) g I-TEQ, respectively. In general, the uncertainty on the estimates is very high, and recommendations regarding further development of the inventories have been made, and measures for reducing the releases have been provided.  相似文献

The impact of the management of packaging waste on the environment, economic growth and job creation is analyzed in this paper. This integrated assessment intends to cover a gap in the literature for this type of studies, using the specific case study of the Portuguese packaging waste management system (SIGRE).The net environmental benefits associated with the management of packaging waste, are calculated using the Life Cycle Assessment methodology. The results show that, for the categories studied, the impacts associated to SIGRE's various activities are surpassed by the benefits associated to material and energy recovery, with special focus on recycling. For example, in 2011 SIGRE avoided the emission of 116 kt CO2 equiv. – the equivalent carbon emission of the electricity consumption of 124.000 households in Portugal.The economic impact of SIGRE is evaluated through Input–Output Analysis. It was found that SIGRE's activities also have a significant economic impact. For example, their added value are ranked amongst the upper third of the economic activities with highest multiplier effect at national level: this means that for each Euro of value added generated within SIGRE, 1.25 additional € are added to the rest of the economy (multiplier effect of 2.25).Regarding the social impacts of SIGRE, the number of direct jobs associated with the system is estimated to be more than two thousand and three hundred workers. Out of these, 83% are connected to the management of municipal waste packaging (selective collection and sorting), 15% are connected to the management of non-municipal packaging waste and only 2% are connected to the Sociedade Ponto Verde (SPV, green dot society in English) – the management entity responsible for SIGRE.In general terms, the results obtained provide quantitative support to the EEA (2011) suggestion that moving up the waste hierarchy – from landfilling to recycling – creates jobs and boosts the economy.  相似文献

Zusammenfassung  Weltweit existieren derzeit weniger als 20 Inventare, die Dioxin- und Furanemissionen absch?tzen. Demnach werden von 16 L?ndern ca. 12.900 g TEQ in die Atmosph?re als unerwünschte Nebenprodukte emittiert. An der Spitze der Emittenten stehen die dichtbev?lkerten Industriel?nder der n?rdlichen Hemisph?re — Japan, Vereinigte Staaten. W?hrend die metallverarbeitenden Industrien in Europa der Sektor mit den h?chsten Dioxinemissionen ist, steht die Müllverbrennung bei den meisten anderen L?ndern an der Spitze. Dioxinmin-derungsmassnahmen in z.B. Deutschland und Japan haben zu starken Rückg?ngen der Emissionen geführt; weitere Minimierungspotentiale bestehen. Die bisher von den verschiedenen L?ndern erstellten Bilanzen verwendeten bisher eigene Methoden und sch?tzten vor allem die Emissionen in die Luft ab. Die künftige Stockholm Konvention zur Eliminierung von POPs verlangt, dass die Dioxinemissionen st?ndig reduziert werden. UNEP gibt hierzu mit seinem Toolkit Hilfestellung, vergleichbare Inventare zu erstellen, die die Emissionen in Luft, Wasser, aufs Land, mit Produkten und in Rückst?nden erfassen.

This article will briefly outline the origins, structure and functions of United Nations Environment Program and the Commission on Sustainable Development in the context of the goals of ecologically sustainable development (ESD). Economic development, social development and environmental protection form the three interconnected parts of ESD. The achievements of the key UN environmental institutions and programs in opening up the global system to civil society, the private sector and a diversity of actors and interests, promoting the role of poverty alleviation as part of ESD through the Millennium Development Goals, and facilitating important Multilateral Environmental Agreements should be recognized. However, with these notable exceptions, organizations such as United Nations Environment Program and the Commission on Sustainable Development have become weak in scientific and technical leadership, global policy, co-ordination (inside and outside the UN) and has few achievements in the inter- national and national implementation of obligations and standards in Global Environmental Governance - including enforcement, compliance and effectiveness. This article will outline the key reasons for this inadequacy. Attention will also be focused on the way forward through of a new United Nations Environment Organization. This will require a clarification of purpose and function (within the UN system and as part of global governance structures) as well as consideration of whether it depends on system-wide UN reform. It is recommended that medium and long term strategies for reform are necessary.  相似文献

Olympic shooters discharge, annually, thousands of tons of lead shot which pose toxic risks to animals and may pollute both surface and ground waters. Non-toxic steel shot is an acceptable and effective substitute, but International Shooting Sports Federation (ISSF) rules prevent its adoption. The present policy and rules of the ISSF on lead shot use contravene the International Olympic Committee (IOC) Charter position on environmental protection. The United Nations Environment Programme (UNEP), a formal Olympic partner on environmental protection, has no stated policy on contamination from lead ammunition, despite having declared lead a Priority Area for remedial action, and is pressing to remove lead from the global human environment. The IOC Sport and Environment Commission and UNEP could examine the continued use of lead shot ammunition and advise the IOC Executive Board on appropriate changes in policy and rules that could halt the massive lead shot contamination of shooting range environments world-wide.  相似文献
