建设项目竣工环境保护验收监测的内涵、缺陷及对策

在环境换取经济增长向环境优化经济增长转变的新形势下,应拓展建设项目环境保护设施竣工验收监洲的内涵.指出目前的竣工验收监测对工业生产型建设项目的制约因素考虑不周、忽视了"三同时"的全过程、忽视了非工业生产型建设项目和区域性开发项目、忽视了无组织排放污染源.提出要创新治理设施竣工验收监测理念、优化竣工验收监测方法、强化竣工验收生态监洲技术的研究、开展区域性建设项目的验收监测.     

某城市建筑泥浆污染现状调查研究

以某城市为例,研究城市建筑泥浆的污染现状,并分析泥浆受到污染的原因.结果表明:对照《地表水环境质量标准》(GB 3838-2002)中的Ⅳ类标准限值,调研的4个工地泥浆水全部超标;该城市地层土壤中的有机质、总氮、总磷含量高是泥浆水超标的重要原因,工地制浆使用的地表水和污水也不能满足Ⅳ类水质的要求.在建筑工地的管理中,应...     

Exploring the perceived influence of safety management practices on project performance in the construction industry

Although safety management is known to be vital to construction projects, very few studies have solicited views from construction practitioners about their perceptions of which safety management practices (SMPs) are important to construction projects and related to project performance. An empirical study was undertaken in Hong Kong in order to shed more light on this topic. In the study, the importance levels of 15 popular SMPs and five project performance criteria were rated by 232 respondents. An exploratory factor analysis was conducted, and three SMP categories - information, process, and committees - were extracted. Of these three categories, safety management process was perceived by the construction practitioners as being the most important, followed by safety management information and committees. Moreover, the effect of the three SMP categories on a composite project performance variable was tested using hierarchical regression analysis. Results indicate that the “information” and “committees” categories were associated with project performance positively and significantly. One of the major conclusions of the study is that the construction industry has paid relatively less attention to safety management committees, which were empirically analyzed as having a strong perceived impact on project performance. In order to improve project performance, construction companies should promote the criticality of safety management committees.

The SeKT joint research project: definition of reference conditions, control sediments and toxicity thresholds for limnic sediment contact tests

- In current biotest approaches, intact organisms or in vitro systems are exposed to sediments using different exposure scenarios. The most important issue in sediment toxicity testing protocols is the question which test phase (solid or liquid) should be used. Whole-sediment exposure protocols represent the most realistic scenario to simulate in situ exposure conditions in the laboratory. However, until now there is no agreement in how to acquire and to evaluate the data of the various available sediment contact assays. The SeKT joint research project was initiated with the aim to compare recently developed sediment contact assays by addressing reference conditions, control sediments and toxicity thresholds for limnic sediment contact tests.
