公路隧道中可吸入颗粒物化学组分特征研究

为了解公路隧道中可吸入颗粒物污染水平及化学组分特征,笔者于2006年9月1日在交通繁忙的石黄隧道中间及入口处进行了可吸入颗粒物（PM10）同步采样,并对样品进行了化学成分分析。根据PM10质量浓度监测以及样品的元素、OC＼EC及离子成分分析结果,对隧道口及隧道中的PM10的污染状况和化学成分特征进行了对比分析。PM10浓度监测和化学成分分析结果表明：石黄隧道环境空气中PM10质量浓度明显高于隧道外的浓度,隧道内PM10污染比较严重;隧道内PM10的离子浓度明显低于隧道外,而OC、EC浓度则又明显高于隧道外,另外其元素中Ca、Al、Si等浓度也明显高于隧道外,这些化学成分特征显示,隧道内的PM10主要来源于机动车尾气及道路扬尘。     

A room for living: Private and public aspects in the experience of the living room

This paper presents findings from a study on people's uses and experiences of their living rooms. The researcher conducted in-depth interviews with sixteen middle-class residents of the Metropolitan New York area. Interviews were conducted in participants' living rooms, and were supplemented by observations, sketches and still-photographs. In the past, social scientists have viewed the living room as serving the purpose of communicating the dwellers' image to guests. Findings from the present study show that dwellers may use their living rooms not only to host guests, but also for their own solitary uses, as well as for sharing time with partners. All uses were found to be meaningful and pertinent to the dwelling experience. Findings also reveal that the living room may provide opportunities for intimacy between dwellers and their partners, as well as between dwellers and their guests. For all participants living rooms contained objects that were highly meaningful to them. It is suggested that objects in the living rooms are used to instigate and mediate contemplation about significant others, as well as to regulate the amount of intimacy desired with guests.

Comparing the utility of image algebra operations for characterizing landscape changes: the case of the Mediterranean coast

The aim of this study is to compare various image algebra procedures for their efficiency in locating and identifying different types of landscape changes on the margin of a Mediterranean coastal plain, Cukurova, Turkey. Image differencing and ratioing were applied to the reflective bands of Landsat TM datasets acquired in 1984 and 2006. Normalized Difference Vegetation index (NDVI) and Principal Component Analysis (PCA) differencing were also applied. The resulting images were tested for their capacity to detect nine change phenomena, which were a priori defined in a three-level classification scheme. These change phenomena included agricultural encroachment, sand dune afforestation, coastline changes and removal/expansion of reed beds. The percentage overall accuracies of different algebra products for each phenomenon were calculated and compared. The results showed that some of the changes such as sand dune afforestation and reed bed expansion were detected with accuracies varying between 85 and 97% by the majority of the algebra operations, while some other changes such as logging could only be detected by mid-infrared (MIR) ratioing. For optimizing change detection in similar coastal landscapes, underlying causes of these changes were discussed and the guidelines for selecting band and algebra operations were provided.

Exploratory Analysis of the Winter Chemistry of Five Lakes on the North Slope of Alaska1

Abstract: Lakes are important water resources on the North Slope of Alaska. Freshwater is required for oilfield production as well as exploration, which occurs largely on ice roads and pads. Since most North Slope lakes are shallow, the quantity and quality of the water under ice at the end of winter are important environmental management issues. Currently, water‐use permits are a function of the presence of overwintering fish populations, and their sensitivity to low oxygen concentrations. Sampling of five North Slope lakes during the winter of 2004‐2005 shed some light on the winter chemistry of four lakes that were used as water supplies and one undisturbed lake. Field analysis was conducted for oxygen, conductivity, pH, and temperature throughout the lake depth, as well as ice thickness and water depth. Water samples were retrieved from the lakes and analyzed for Na, Ca, K, Mg, Fe, dissolved‐organic carbon, and alkalinity in the laboratory. Lake properties, rather than pumping, were the best predictors of oxygen depletion, with the highest dissolved‐oxygen levels maintained in the lake with the lowest concentration of constituents. Volume weighted mean dissolved‐oxygen concentrations ranged from 4 to 94% of saturation in March. Dissolved oxygen and specific conductance data suggested that the lakes began to refresh in May.

如何应对发达国家的环境保护壁垒

20世纪90年代以来,环境保护已成为世界各国政府关注的首要问题之一.出于保护本国消费者生命健康和生态环境的考虑,发达国家纷纷把环境保护壁垒作为其贸易壁垒的主要组成部分.我国作为世界上最大的发展中国家,近年来在对美国等发达国家的贸易中保持了较大的顺差,且出口产品多为劳动密集型产品,因此受到发达国家环境保护壁垒的限制也较严重.从政府和企业两方面入手,讨论我国应如何应对发达国家的环境保护壁垒.
