安太堡露天煤矿复垦地土壤养分相关研究

以平塑安太堡露天煤矿为例，研究了矿区排土场矸石风化物和黄土二种主要母质发育的土壤有机质、全氮、速效磷、速效钾状况及其相关性。结果表明，矸石和黄土母质对有机质、全氮的影响显著，对速效磷、速效钾的影响未达到显著水平；黄土母质发育的土壤有机质和全氮含量呈显著正相关，而矸石风化物有机质和速效钾含量呈显著负相关，有机质和其它的养分指标相关性不显著。     

Organochlorine pesticides in surface soils and sediments from obsolete pesticides dumping site near Lahore city,Pakistan: contamination status and their distribution

Surface soil and sediment samples were collected from the surroundings of Lila stream, which passes through the obsolete pesticides dumping area Kalashah Kaku near Lahore city, to evaluate the residual levels of 19 organochlorine pesticides (OCPs), their distribution and potential sources. OCPs followed the order: ∑ DDT>∑ HCH>dicofol>endrin>heptachlor>dieldrin. Ratios of β to γ-HCH highlighted an old source of technical HCH in the study area, whereas the predominance of p, p′-DDT and p, p′-DDE indicated presence of technical DDT in surface soils. Factor analysis based on principal component analysis identified the origin of OCPs from industrial activities in Kalashah Kaku and waste dumping from Ittehad Chemical Industries via open drains into Lila stream. Greater levels of DDTs and HCHs above quality guideline pose potential exposure risk to biological organisms, safety of agricultural products and human health in the surrounding of Lila stream.

现代卫生填埋工程研究与分析

现代卫生填埋工程是一种安全、有效、有控制地处理城市固体废弃物的方法,其涉及众多学科,属于环境安全、生态安全、工业安全、卫生安全共同关注的问题。城市及工业废料的卫生填埋工程目的是实现减量化、无害化和资源化,形成一个安全、有效、严格控制、环境生态保护,经济化、无害化、资源化科学发展的循环体系。笔者介绍国内外现代卫生填埋工程的研究概况,详细论述现有填埋场的研究内容,指出其中存在的主要问题与不足,并在此基础上探讨了该领域的发展趋势及研究方向。     

填埋场垃圾体的安全稳定性分析

卫生填埋场是一种安全经济、行之有效的固体废弃物最终处置方案。笔者总结分析了固体废弃物填埋场边坡不稳定问题以及其稳定破坏的类型和破坏机理,影响填埋场垃圾体稳定性的因素等,研究表明固体废弃物的强度指标、填埋体中淋滤液的饱和度、边坡角度和浸润线的埋深,以及填埋年代等因素都会影响填埋场垃圾体的稳定性。在此基础上,指出了目前填埋场垃圾体稳定问题研究的不足,提出了相关建议。     

Industrial waste management simulation game and its educational effect

The purposes of this study were to develop the Industrial Waste Game and to examine the validity of this game as a tool for environmental education. The aim of this game is to enable players to understand the social dilemma between individual interest of hazardous dumping and the social cost of purifying pollution, and to find a solution to the social dilemma by providing the monitoring and sanction system for illegal dumping or other efficient systems. The game was played by 213 undergraduate students who were divided into 40 groups of 5 to 6 people. One of 4 combinations of monitoring and penalty conditions was assigned to each group. The players were asked to answer questionnaires concerning their interests and understanding of the industrial waste issue before and after the game to evaluate educational effects. The results indicated that the players increased their awareness of industrial waste problems and came to understand that these problems were caused not by psychological factors such as immorality of the illegal dumper but mainly by social structural factors like the social dilemma. Through playing the game and participating in post-game discussion, players were able to obtain interesting experience and gain motivation to learn more.
