SOIL ZINC CONTAMINATION FROM CORROSION OF GALVANIZED STRUCTURES

The present work relates to galvanized structures with several years of time life subjected to atmospheric corrosion, like galvanized high tension steel pylons. The mass and fate of zinc released is evaluated both via empirical and experimental procedures. The corrosion rate determination requested atmospheric condition characterization, especially for SO 2 concentration and experimental activities focused on soil sampling around pylons. The soil zinc content, total and exchangeable, is determinates by different analytical procedures. The zinc diffusion in environment and the zinc extension under the top soil is evaluated using 1-dimensional mathematical model for miscible species in porous soil.     

大气污染对女性成人肺通气功能影响的研究

对重庆市不同大气污染地区女性成人的肺爱气功能和生活环境因素的调查后性发现，大气污染区女性成人的ＦＶＣ、ＦＥＶ、及Ｖ７５、Ｖ５０等肺功能指标显著低于清洁区；运用逐步回归分析显示，ＳＯ２浓度、年龄、身高及被动吸烟与ＦＶＣ关系密切，典型相关分析提示，肺功能与生活环境因素的相关主要表现为ＦＶＣ、ＦＥＶ、及Ｖ２５与年龄、ＩＰ浓度和烧煤的相关。     

Urban development grant — an early assessment of regional implications

An examination of the Urban Development Grant during its first round of operation reveals that certain regions, particularly the West Midlands and London, are winning considerably more funding than others. A change in this trend is likely to require a reassessment, by the Government, of the targetting criteria presently used to direct the grant to areas of need.     

地震减灾体系中的区域联防问题

地震灾害是我国主要的自然灾害之一。现阶段,减轻地震灾害的主要途径是在努力提高地震监测预报水平的基础上,发挥政府、社会和地震科技队伍三方面的作用,坚持以预防为主,建立地震减灾工作体系,走综合减灾的道路。行使政府职能是地震减灾工作体系的中心环节,职能的行使以一级政府的行政管辖范围为“边界”。但我国大陆地区已发生的大震和当前的重点监视防御区多分布于二省、三省或更多省市交界地区。突破行政区划,在地震活动区、危险区周围协调地开展监测、预报、宣传、防御工作是当前进行防震减灾战略布局所必需。地震科学发展的“跨”行政区划和政府行政职能的严格区划性的尖锐矛盾,有必要提出地震减灾中的区域联防问题,本文是有关这个问题的分析与建议。

Mapping sediment contamination and toxicity in Winter Quarters Bay,McMurdo Station,Antarctica

Winter Quarters Bay (WQB) is a small embayment located adjacent to McMurdo Station, the largest researchbase in Antarctica. The bay is approximately 250 m wide andlong, with a maximum depth of 33 m. Historically, trashfrom the McMurdo Station was piled on the steep shoreline ofWQB, doused with fuel and ignited. That practice hasceased, and the adjacent land area has been regraded tocover the residual waste. The bottom of WQB remainslittered with drums, equipment, tanks, tires, cables, andother objects, especially the southeastern side of the baywhere dumping took place. Sediments are contaminated withPCBs, metals, and hydrocarbon fuels. The objectives of this study were to map the distributionof organic contaminants in WQB, assess the toxicity of WQB sediments using a simple microbial test, anddetermine correlations between toxicity and contaminantlevels. The study suggests that adverse ecological effectshave occurred from one or more of the contaminants found inWQB but the source of the toxic impacts to bay sedimentsremains unknown. Whole sediment toxicity was onlycorrelated with oil-equivalent while solvent extracts ofsediments were correlated with PAHs and oil-equivalent. Theauthors recommend that an integrated research plan bedeveloped that focuses on determining what additionalinformation is needed to make informed decisions on possibleremediation of WQB.     

Theory and practice of EIA implementation: A comparative study of three developing countries

This article offers a conceptual framework for analyzing institutional processes and performance outcome of EIA implementation for developing countries. Eight classes of participants in the EIA process are identified: (1) responsible agency; (2) action proponent; (3) preparer; (4) review agency; (5) rule-setting agency; (6) concerned agencies; (7) general public; and (8) licensing agency. Five types of performance outcome are suggested that may follow the introduction of EIA into a national planning system. These include EIA as (1) a fully internalized element of the planning process, (2) a support for a position of advocacy for the environment, (3) a process of adjustment among conflicting goals, (4) a process to remedy prior environmental damage, and (5) a perfunctory endorsement of public or private actions. Using these categories, the EIA system of the Philippines, Korea, and Brazil are analyzed. Three aspects of EIA implementation are compared: national development planning and environmental goals; institutional structure; and performance evaluation. Based on this analysis, the author concludes that while EIA in developing countries is being hampered in its early stages by institutional factors, there are some specific policies that, if adopted by national governments and international aid agencies, would enhance the integration of EIA into the planning and decision-making process and make EIA a more effective tool for environmental protection in the developing world.
