苏州河的污染底泥评价

以底泥与流动水相的边界环境为研究对象，应用苏州河底的释放与耗氧规律，在控制地面水水质标准的环境基础上拟定了底泥评价分级标准，将评价的有机污染指标确定为未污染，污染、重污染底泥的类型级别。应用拟定的分级标准对苏州河的污染底泥进行评价，指出若对属于重类型的部分河段底泥进行整治，则整个市区段底泥释放至水相的深度，将接近地面水三级标准。

Assessments and decisions in Metellina segmentata (Araneae: Metidae): evidence of a pheromone involved in mate guarding

Assessments and decision-making underlying the initiation of mate guarding in a common web-building spider, Metellina segmentata, are examined in a series of field and laboratory studies. Adult males do not build webs but wander in search of females and mating opportunities. Adult males then wait at the edge of the webs of females and guard them prior to courtship and mating. Guarded females were heavier, larger and carried more mature eggs than solitary females. An active process of information gathering is apparent from introductions of males to the webs of females. Males make accurate assessments about female quality, even in the absence of the resident female. Cues involving web architecture are not used. Males may assess pheromonal cues on the web of the female in deciding whether to guard or abandon a female.

Life cycle assessment as a decision support tool for landfill gas-to energy projects

The greenhouse gas (GHG) emissions from MSW landfill, and control methods to eliminate or minimize these impacts including energy recovery from landfill gas (LFG) of MSW landfill in Thailand have been evaluated. Life Cycle Assessment (LCA) is used as the analytical tool to evaluate the environmental consequences of landfilling holistically. The economic implications of the control methods are also briefly assessed. The results show that in terms of GHG emissions as well as in terms of economics, it is more advantageous to have a large centralized landfill and produce electricity from the LFG rather than having several small, localized landfills despite significantly lower transportation requirement for the latter case. Sensitivity analysis revealed that the global warming potential was sensitive to gas collection efficiency as well as methane oxidation rate in the landfill. This study shows the utility of a life cycle approach for evaluating LFG-to-energy (LFGTE) projects.
