Evidence for biodegradation and volatilisation of dissolved petroleum hydrocarbons during in situ air sparging in large laboratory columns

Laboratory column experiments run for up to 13 days compared air sparging of groundwater contaminated by dissolved petroleum hydrocarbons in sterile and non-sterile aquifer sediments as well as uncontaminated sediments and groundwater. Loss of dissolved BTEX compounds in the contaminated columns was very rapid, occurring through volatilisation. The majority of the dissolved total organic carbon (TOC) persisted for much longer periods however. A direct comparison between losses from sterile and non-sterile columns suggested a negligible contribution of biodegradation to the removal of TOC. This was difficult to confirm through examination of O₂ utilisation because oxidation of a small amount of reduced sulphur in the aquifer materials was the dominant sink for O₂. Despite this, it was possible to conclude that less than 22% of the removal of TOC was through biodegradation during the first three days of air sparging.     

环境医学：人类生存发展战略的大课题

文章用大量翔实数据，分析论证：人类由于淡化环境意识，坚持急功近利的片面发展观，造成整个地球环境质量正在全面下降和恶化，全球已有１／５的人口受到环境污染之害的基点上，作者提出了只有跳出以自我生存为中心的狭隘圈，确立发展环境医学为主体的预防医学战略，并提示要遵循中国古代强调的“天人合一”论概念和钱学森提出的“开放的巨系统方法论”在当代科技领域进行“天地生人巨系统的综合集成研究”，树立“天地与我并生，万物与我同运”的自然生态观，为创建“生物心理社会自然”为模式的全科新医学，这是实现２１世纪“人类健康工程”的开拓性目标。

Analysis of Lower Green Bay and Fox River,Collingwood Harbour,Spanish Harbour,and the Metro Toronto and Region remedial action plan (RAP) processes

This article presents a model of remedial action planning, which includes four key variables that determine progress in plan development and implementation and explain the differing level of achievement in individual sites. The model is illustrated by the characteristics and developments of four remedial action plan (RAP) processes (Lower Green Bay and Fox River, Collingwood Harbour, Spanish Harbour, and the Metro Toronto and Region RAPs). Differences in the local context of the plans have, to a significant degree, predisposed individual planning and implementation experiences. Local context includes three variables, namely geographical—technical and sociopolitical aspects and the previous history of water pollution management in the area. RAP precursors are a necessary precondition for progress in planning and substantive achievements. While there is a tendency that most geographically focused RAPs in administratively simple areas accomplish most, the motivation and political clout of RAP participants are strongly intervening factors. Resource input from upper levels of government, in particular financial commitment for plan implementation, is the fourth necessary ingredient for progress due to the RAPs' weak regulatory and institutional framework. Unfortunately, upper levels of government have shown widespread reluctance to lead in remedial action planning. This was only in part offset by local commitment and support for RAP and its cause.     

胜利油田生活污水调查及评价

随着人民生活水平的提高，城市人均用水量逐年增加，伴随产生的生活污水已经成为不可忽视的污染源。胜利石油管理局供水公司于１９９３年对胜利油田的污水排放情况进行了调查，调查各单位职工住宅区和机关办公区所排放的生活污水的情况，包括排放生活污水单位的名称、人数、生活用水量、污水排放量和污水水质等，并提出了生活污水的治理对策。
