10 years ago, the WWF (World Wide Fund for Nature) began to support the work of environmental protection in the countries of Eastern Europe. A main topic is the Danube-Carpathian Program. With the beginning of the bombardements, connected with great amounts of chemicals released directly and as clouds from the fires and explosions, the question raises: What are the consequences for mankind and nature? Is there a risk for the Danube-Carpathian Program? The WWF feels responsible for reporting about these consequences. In July 1999, a group of two Oil Experts and two scientists (each a chemist and a toxicologist) visited Belgrad, Pan?evo and Novi Sad, took samples of soil and water, and estimated the contents of dangerous substances. The first findings and the first consequences for nature and human health are described. 相似文献

Wastes from three different types of waste treatment facilities (slag from a municipal waste incineration plant, slag granules from a pilot plant combining carbonization and incineration, mechanical and biological treated wastes) were examined to determine their hazard potential to different waters sites. The process temperature is seen to be the main difference between the three treatment processes. The wastes were extracted with water according to the German standard DIN 38414 S 4 and additionally at a constant pH value of 4. The leachates were investigated in a battery of aquatic bioassays and characterised physically and chemically. Every leachate revealed in a toxic effect at least in one test. The toxicity of the leachates prepared at a pH of 4 was significantly higher than the toxicity of the leachates prepared by extraction with water without pH adjustment. The leachates of the slag granules showed the lowest toxicity. On the basis of these experimental results, a scheme to derive Water Hazard Classes of wastes, which is presented in part II of this publication, was developed. 相似文献

ABSTRACT In August 1995, measurements of CO, NOx, speciated nonmethane hydrocarbons (NMHC), and CO2 were made in Vancouver's Cassiar Connector, a 730-m-long level-grade highway traffic tunnel. Two characteristics of the Vancouver setting are the presence of many propane vehicles and a mandatory inspection and maintenance (I/M) program. Although the driving conditions and vehicle fleets are otherwise outwardly similar to those of recent Tuscarora-tunnel studies, CO/NO ratios at the Cassiar Connector are significantly lower than those measured at Tuscarora. The Cassiar measurements are consistent with the MOBILE5A mobile emissions model predictions. The Canadian version of MOBILE5A—known as MOBILE5C—gives nearly identical results, indicating that differences in Canadian and U.S. emission standards cannot explain differences between Cassiar and U.S. tunnels. Considering the modeling results as well as measured ethene/acetylene ratios indicative of noncatalyst vehicles, it appears that vehicle deterioration remains the major issue in in-use vehicle emissions—even in Vancouver, where there is a mandatory loaded-mode I/M program. 相似文献

In order to ensure equality of occupational health care among employees of small and medium-sized enterprises (SMEs) and of larger companies, amendments in the regulations of the numerous German accident insurance funds had to be made to provide for full availability of services, as requested by German and European law. According to these amendments, sectors formerly exempted due to small size and due to lack of an adequate number of qualified personnel, had to be covered by occupational health care. In order to reach this target group new strategies of care delivery had to be developed, making use of pre-existing infrastructure and networks.In Germany, district trade association (Kreishandwerkerschaften) have proved to be very effective for introducing occupational safety and health care into SMEs by either hiring external multidisciplinary services or by establishing a common service to be used by all associated crafts establishments. In a study conducted by the Federal Office for Health and Safety at Work in 1996 (Boldt, Gille, &Grahl, 1997), 7 district trade association were looked at in detail for their strategies. The results were discussed and supplemented in a 2-day workshop. 相似文献

Although intrinsically a global environmental concern, the climate change issue has a number of implications for local authorities. Within the European Union (EU), the remit of local authorities in—-for abatement policies—the crucial areas of energy and transport policy varies considerably, as does their commitment to environmental action more generally. This paper examines the role of local authorities in climate protection within a framework of global, EU and national action, through examples of local strategies from Germany, Italy, Spain, Sweden and the UK. The paper finds positive instances of action in all countries, but points to unsympathetic policy frameworks both at national and EU level, such as budget constraints imposed on local authorities, the pursuit of low energy prices combined with a resistance to impose carbon taxes, a lack of energy efficiency standards and insufficient support for public transport. 相似文献

Zusammenfassung Der WWF (World Wide Fund for Nature), Initiator und Tr?ger des Donau-Karpaten-Programms, besch?ftigt sich seit Beginn des
Kosovo-Konfliktes mit den Auswirkungen der kriegerischen Auseinandersetzungen auf Natur und Mensch und versucht, die Welt?ffentiichkeit
entsprechend zu informieren. Ende Juli 1999 hat der WWF International eine Mission, bestehend aus unabh?ngigen Toxikologinnen
und ?lexperten, an die Donau entsandt. Unter der Leitung von Philip Weller, dem Direktor des WWF Donau-Karpaten-Programms,
wurden drei Tag lang Industriekomplexe besichtigt und Gespr?che mit Betroffenen geführt. Die Reise führte das Team nach Panćevo
und Novi Sad, und damit zu den Schwerpunkten der zerst?rten Chemie- und Petrochemischen Komplexe. In den betroffenen Werken,
HIP AZOTARA, Panćevo und NIS ?lraffinerie, Novi Sad wurde das Team von den jeweiligen Werkleitern geführt. Gespr?che fanden
statt mit dem Bürgermeister von Panćevo und Vertretern des Gesundheitsamtes in Belgrad. Es war dem Team m?glich, Boden- und
Wasserproben zu nehmen und zu analysieren. Damit liegen den Autoren unabh?ngige Analysenergebnisse vor, die es gestatten,
eine erste, orientierende Einsch?tzung der Kontaminationen vorzunehmen.

Seabird eggs were used as bioindicators of chemical contamination in Chile. Brown-hooded Gull (Larus maculipennis), Kelp Gull (Larus dominicanus), Trudeau's Tern (Sterna trudeaui), Neotropic Cormorant (Phalacrocorax brasilianus), and Pink-footed Shearwater (Puffinus creatopus) eggs were sampled at different breeding sites during the 1990s. Mercury and organochlorines (PCBs, DDT, HCB, HCH, and PCP) were quantified to reveal the interspecific differences, spatial and temporal trends in contamination levels. Trudeau's Tern displayed the highest levels of mercury (486 ng g(-1) wet weight). The highest sumDDT concentrations were measured in Brown-hooded Gulls (726 ng g(-1)). PCB levels were similar among the species (102-236 ng g(-1)), but the composition of the PCB mixture was different in Pink-footed Shearwaters. With the exception of the Brown-hooded Gull, all species studied presented similar and low levels of organochlorines (sumOHa). Residues of PCB and related compounds were not detected in any of the seabird eggs analyzed in Chile. Geographical variation was low, although levels of industrial chemicals were slightly higher in eggs from Concepción Bay, and agricultural chemicals in eggs from Valdivia. Also interannual variation was low, but some evidence was found of decreasing levels in gull eggs throughout the time of the study. The causes of the low levels and small variability in space and time of environmental chemicals in Chilean seabirds are discussed. We propose the use of seabirds in future monitoring of the development of chemical contamination in Chile. 相似文献
