A comparison of new economic methods in USSR environmental policy with western approaches

Previous comparative studies on environmental policies in the East and West mainly focused on relating differing features of environmental management to different political, social/economic, and ideological conditions in both systems. The present article attempts to identify common experiences. In this respect, an obvious similarity can be seen in the fact that environmental management in the East and West emerged as a regulatory “command and control” approach, which was supplemented later by economic incentives. The 1988 USSR Resolution “On the Radical Transformation of the System of Natural Conservation” introduces a set of economic instruments as one of its main elements. This is less a radical change of environmental policy than a determined acceleration of previous approaches. Existing and newly designed economic methodologies provoke a comparison with similar approaches in market economies. The economic methods designed in the 1988 resolution include charges for the use of natural resources and the emission of pollutants, which are notable for their firm commitment to reduce emissions even below set regulatory standards. While experiences with this approach may be of great interest for Western countries, liability regulations of the United States can be of great use for designing relevant provisions implementing the USSR resolution. A number of bilateral treaties have demonstrated already the political relevance of an East-West exchange of experience in environmental management.     

How shell cleaned up a 400,000-gallon oil spill

On April 23, 1988, approximately 9,500 barrels (400,000 gallons) of San Joaquin Valley crude oil leaked from an aboveground storage tank at Shell Oil Company's Martinez Manufacturing Complex in Martinez, California and entered Suisun Bay, an important recreation area. This article describes the remediation techniques Shell used to protect and clean up the Bay's oiled marshes, sloughs, rocky shores, marinas, and sandy beaches, and discusses the main methods of oil spill response, site-specific factors that must be considered in choosing remediation techniques, the interaction between Shell and government agencies, and the costs associated with the spill. The cleanup's total cost was approximately $8.3 million, which did not include private claims and claims handling costs; Shell also signed a separate consent decree for $19.75 million with the state of California and the federal government. This spill and its aftermath emphasize the need for preparation that facilitates response actions, improves the chances for cooperation between responsible parties and government agencies, minimizes the time needed for remediation, lowers cleanup costs, and limits natural resource damage claims and penalties.     

Chemisch-analytische Untersuchung von Arsenkampfstoffen und ihren Metaboliten

Zusammenfassung  Arsenkampfstoffe sind in der Umwelt persistent und kontaminieren bis heute Boden und Grundwasser. In diesem Beitrag werden die chemischen Reaktionen der Arsenkamptstoffe Diphenylarsinchlorid (CLARK I), Phenylarsindichlorid (PFIFFIKUS), Ethylarsindichlorid (DICK) sowie von Chlorvinylarsinverbindungen (LEWISITE) dargestellt. Die M?glichkeiten der chemisch-analytischen Erfassung dieser chemischen Kampfstoffe als Originalsubstanzen und als Thiol-Derivate werden pr?sentiert.      

Both reindeer management and several other land use factors explain the reduction in ground lichens (Cladonia spp.) in pastures grazed by semi-domesticated reindeer in Finland

Roles of intensive reindeer grazing and several additional land use factors in the reduction in ground lichens (Cladonia spp.) in pastures grazed by the semi-domesticated reindeer have been argued in Finland. Our analysis showed that several factors and processes explain the standing biomass of lichens (during 2005–2008) and the recent changes in this biomass (after 1995–1996) on lichen pastures located in the 20 northernmost herding districts in Finland. The higher the long-term reindeer densities on the lichen pastures the lower was the lichen biomass. The lichen biomass was also strongly affected by the grazing system; the lowest biomass values of lichens were measured in all grazing areas that were used in the snow-free seasons. The lichen biomass in pine forests less than 80 years old and in all mountain type lichen pastures was lower than that in mature and old pine forests. The lichen biomass also decreased as the proportion of arboreal lichen pastures within a district decreased and the proportion of human infrastructure increased. The aerial drift of heavy metals from the Kola Peninsula appeared to reduce lichens in a small north-eastern part of the study area. Increases in summer precipitation and winter temperatures increased the amount of lichens, but increases in summer temperatures and winter precipitation had the opposite effect. Reindeer densities, grazing system, pasture type and the previous abiotic factors were also associated with the reduction in lichen biomass between the inventories. We conclude that several local, regional and even global factors and processes affect the state of reindeer pastures in large and complex grazing ecosystems. Therefore, more comprehensive research and management strategies for the entire reindeer herding environment are needed.

Sources and Source Strengths of Volatile Organic Compounds in a New Office Building

This study was conducted at a newly constructed federal office building in Portland, Oregon. The primary objectives were to identify the major sources of volatile organic compounds (VOC) in the building and to measure both long-term (one year) and short-term (several day) variations in concentrations and source strengths. Samples for VOC were collected on four occasions over a period of 14 months starting with the first month of occupancy. During the final sampling period, samples were collected over four days (Friday - Monday). The samples were analyzed for individual compounds and for total VOC (TVOC). The results were expressed as specific source strengths, as well as concentrations, to facilitate comparisons of measurements made under different ventilation conditions.

The primary source of VOC in the building was identified as liquid-process photocopiers and plotters which emitted a characteristic mixture of C10-Cn isoparaffinic hydrocarbons. The specific source strength of TVOC, which was dominated by the emissions from these office machines, remained relatively constant over the course of the study. Motor vehicles in the below-ground parking garage were implicated as another major source of hydrocarbons in the building. Over the final four-day sampling period, the specific source strength of TVOC varied by about a factor of five, predominantly reflecting occupant use of office machines.     

大气污染物监测数据不确定度评估方法体系建立及其对PMF源解析的影响分析

目前,正定矩阵因子法(PMF)在大气污染物来源解析中得到了广泛应用,而监测数据不确定度评估是PMF源解析的重要内容之一.当前绝大部分研究采用的数据不确定度仅通过借鉴前人的方法简单计算而得,缺乏对计算方法的合理性和适用性进行评估.本研究通过3种常用的不确定度算法交互应用建立了一套有效评估不确定度的方法体系.通过对香港荃湾站点1998—2008年PM_(10)组分监测数据进行源解析并与平行采样数据源解析结果进行对比,对该方法体系的合理性进行了验证.结果发现,应用该方法体系可以将某些常规方法无法分离的因子进一步分解,得到的源解析结果的残差值甚至小于平行采样方法解析结果的残差值,得到的因子贡献率均处于常规方法得出的因子贡献率之间.这些均表明了该方法体系所得源解析结果的可靠性和全面性.因此,本研究建立的评估不确定度的方法体系具有较强的可行性,对确保源解析结果的准确性有重要意义.
