地下水中氮化物转换的氧化还原条件

地下水中氧化还原电位影响着各种氮化物的分布和浓度变化。计算资料已经用于确定这些化合物之间的Eh—pH边界值。计算条件与地下水中不同形式氮化物的实际资料有所不同。本文给出了一个经验性的氮化物的Eh—pH曲线图,这个经验性的Eh—pH曲线图与地下水中氮化物的实际分布相一致。     

Analytic element ground water modeling as a research program (1980 to 2006)

Scientists and engineers who use the analytic element method (AEM) for solving problems of regional ground water flow may be considered a community, and this community can be studied from the perspective of history and philosophy of science. Applying the methods of the Hungarian philosopher of science Imre Lakatos (1922 to 1974), the AEM "research program" is distinguished by its hard core (theoretical basis), protective belt (auxiliary assumptions), and heuristic (problem solving machinery). AEM has emerged relatively recently in the scientific literature and has a relatively modest number of developers and practitioners compared to the more established finite-element and finite-difference methods. Nonetheless, there is evidence to support the assertion that the AEM research program remains in a progressive phase. The evidence includes an expanding publication record, a growing research strand following Professor Otto Strack's book Groundwater Mechanics (1989), the continued placement of AEM researchers in academia, and the further development of innovative analytical solutions and computational solvers/models.     

伯特兰德定律和温伯格原理及推广

将温伯格原理和伯特兰德定律推广到水文地质单元内不同水文地球化学区，在元素被溶（淋）滤，强烈迁移的水文地球化学区段造成某些元素缺乏，生物生理负效应与元素质量浓度成负相关关系，在元素聚（富）集，溶滤，蒸发浓缩水文地球化学环境区，以及某些元素污染环境造成过量，生物生理负效应与元素质量浓度成正相关关系，在此两者之间为元素质量浓度适宜区，根据山西离柳水文地质单元内研究获得：在元素淋滤，流失水文地球化学区水（土）中缺Se,I,F引起的KBD，IDD，龋齿病证实，其患病率与相应元素质量浓度成负相关关系，在聚（富0集，溶淋区因水（土）中F过量而患的地氟病，患病率与F质量浓度正相关关系。     

Effects of furadan in the brown mussel Perna perna and in the mangrove oyster Crassostrea rhizophorae

Furadan is a carbamate pesticide used widely to combat agricultural pests. However little information is available about the toxicity of furadan in aquatic macroinvertebrates. The in vivo effects of furadan were evaluated in mussels, Perna perna, and oysters, Crassostrea rhizophorae. Glutathione S-transferase (GST), catalase (CAT) and cholinesterase (ChE) activities were measured in the gills of both species exposed to furadan (100 microg/l) for 96 h. No changes were observed in GST activity in the exposed groups. CAT activity was higher (9%) in the oysters exposed to furadan. ChE activity was inhibited by 64 and 35%, respectively, in C. rhizophorae and P. perna exposed to furadan, suggesting that the former is more susceptible to the toxic effects of furadan.
