Current US regulatory air quality monitoring networks measure ambient levels of pollutants and cannot capture the effects of mobile sources at the micro-scale. Despite the fact that overall air quality has been getting better, more vulnerable populations (children, the elderly, minorities and the poor) continue to suffer from traffic-related air pollution. As development intensifies in urban areas, more people are exposed to road-related air pollution. However, the only consideration given to air quality, if any, is based on ambient measures. This paper uses an inexpensive, portable Particle Soot Absorption Photometer (PSAP) to measure Black Carbon (BC) emissions, a surrogate for diesel fuels emissions, in Seattle's International District. With the aid of a GPS receiver, street-level BC data were geocoded in real space-time. It was found that pollution levels differed substantially across the study area. The results show the need for street-level air pollution monitoring, revisions in current land use and transportation policies, and air quality planning practice. 相似文献

Risk is a key topic in the communication between developers of infrastructure projects, permit-granting authorities, and civil society. The nature of risk communication is contested among academics, however. Whereas some scholars conceive of risk communication as a matter of effectively communicating expert knowledge on factual matters to the public, others emphasise the role of symbolic construction and rhetoric. This article analyses how wind farm developers rhetorically construct risks in relation to the environmental impact assessment (EIA) for a large offshore wind farm project. Our analysis is inspired by the New Rhetoric, the theory of argumentation developed by Perelman and Olbrechts-Tyteca (Traité de l'argumentation – la nouvelle rhétorique, Brussels: Éditions des presses de l'université de Bruxelles, 1958). We suggest that the EIA adopt a dual argumentative strategy. The report associates numerous risks with the project by identifying and cataloguing them; however, these risks are also disconnected from the project by being described as nonexistent, negligible, or manageable. We discuss some implications of considering EIAs, not as accounts of reality, but as loci of production for this reality. 相似文献

Some countries, including Taiwan, have adopted strategic environmental assessment (SEA) to assess and modify proposed policies,
plans, and programs (PPPs) in the planning phase for pursuing sustainable development. However, there were only some sketchy
steps focusing on policy assessment in the system of Taiwan. This study aims to develop a methodology for SEA in Taiwan to
enhance the effectiveness associated with PPPs. The proposed methodology comprises an SEA procedure involving PPP management
and assessment in various phases, a sustainable assessment framework, and an SEA management system. The SEA procedure is devised
based on the theoretical considerations by systems thinking and the regulative requirements in Taiwan. The positive and negative
impacts on ecology, society, and economy are simultaneously considered in the planning (including policy generation and evaluation),
implementation, and control phases of the procedure. This study used the analytic hierarchy process, Delphi technique, and
systems analysis to develop a sustainable assessment framework. An SEA management system was built based on geographic information
system software to process spatial, attribute, and satellite image data during the assessment procedure. The proposed methodology
was applied in the SEA of golf course installation policy in 2001 as a case study, which was the first SEA in Taiwan. Most
of the 82 existing golf courses in 2001 were installed on slope lands and caused a serious ecological impact. Assessment results
indicated that 15 future golf courses installed on marginal lands (including buffer zones, remedied lands, and wastelands)
were acceptable because the comprehensive environmental (ecological, social, and economic) assessment value was better based
on environmental characteristics and management regulations of Taiwan. The SEA procedure in the planning phase for this policy
was completed but the implementation phase of this policy was not begun because the related legislation procedure could not
be arranged due to a few senators’ resistance. A self-review of the control phase was carried out in 2006 using this methodology.
Installation permits for 12 courses on slope lands were terminated after 2001 and then 27 future courses could be installed
on marginal lands. The assessment value of this policy using the data on ecological, social, and economic conditions from
2006 was higher than that using the data from 2001. The analytical results illustrate that the proposed methodology can be
used to effectively and efficiently assist the related authorities for SEA. 相似文献
