We have used Groundwater Modeling System (GMS) to numerical simulate the groundwater pollution migration caused by crude oil leak in the research regions. The result of the numerical simulation shows those 40 years after the crude oil leak, the contaminative area of pollutant reaches 46595 m3, and then the pollutant doesn’t arrive the pumping well. The density of the pollutants is less than 0.01mg/L. Therefore, we suggest that pipeline projects should make a specific effective plan for groundwater environmental monitoring for the sake of providing reference to institute relative countermeasure for prevention and control groundwater pollution.

Modiolus Modiolus

Blue mussels, Mytilus edulis, inhabiting tidal zones, are naturally exposed to fluctuating environmental conditions (e.g., fluctuations in temperature and salinities), while horse mussels, Modiolus modiolus, live under relatively invariable shelf water conditions. The present investigation tested the hypothesis: blue mussels, in comparison to horse mussels, have an increased ability to tolerate the stress of pollution combined with low salinity. To assess the response of blue mussels and horse mussels to oil pollution at seawater salinities of 25 psu (normal) and 15 psu (low), we used a combination of heart rate and lipid composition as physiological and biochemical indicators, respectively. A sharp decrease in heart rate as well as important fluctuations in cardiac activity was observed under all oil concentrations. Modifications in the concentrations of the main membrane lipid classes (phosphatidylcholine, phosphatidylethanolamine, and cholesterol) and storage lipids (primarily triacylglycerols) in response to different crude oil concentrations were time- and dose-dependent. Both chosen indicators showed a high sensitivity to crude oil contamination. Furthermore, both bivalve species showed similar responses to oil pollution, suggesting a universal mechanism for biochemical adaptation to crude oil pollution.

Dynamic Damage

To provide a theoretical basis for water prevention and control methods and reasonable supporting techniques for vertical shaft, and to ensure the shaft construction to pass the sandstone aquifer safely and rapidly, numerical simulation using dynamic damage constitutive model, which was a user-defined constitutive modules in FLAC3D, a lagrangian analysis code in three dimensions, has been applied to investigate the dynamic damage effect in the surrounding rock of the grouting curtain near the driving working face for vertical shaft excavated by blasting. The results indicate that the distribution of the damage zone in the surrounding rock of the shaft, which decreases the effective thickness of the grouting curtain, was like a ellip-se, and that the depth of the damage zone in the surrounding rock of the shaft grouting curtain is fewer than that of the driving face floor. It can be concluded that the centre part of the driving face floor, especially the cutting hole zones, and the shaft wall in the greater horizontal stress side are the " key parts " for shaft water prevention and control methods.

Whether one is concerned with the continuing availability of caviar or the state of the beach at Brighton, it is difficult to remain unaware of the almost obsessive attention which is being paid to pollution in general and to marine pollution in particular by a host of institutions, national and international. Not only because the problem is a very complex and many-sided one but also because it is a politically fashionable one, there are very few international institutions which have not felt the necessity to take part in the current debate. One result is that it is rapidly becoming a full-time occupation to collect, digest and assess the ever-increasing volume of documentation, much of which reffects the overlapping spheres of juisdiction of the institutions concerned. The purpose of this paper, therefore, is to present a comprehensive progress report on the work of these institutions, whether their concern be with the prevention and control of marine pollution or with compensation for the damage it causes. It is hoped that such a report will provide a useful framework of reference for a better understanding of the preparations for and results of the several international conferences which are scheduled to meet in the next few years. The paper falls into six main parts. Following an introductory section on the institutional framework within which work is proceeding, parts II-V deal with the substance of that work on the prevention of oil pollution; liability for oil pollution; radioactive pollution; and marine pollution by other hazardous substances. Finally, part VI is devoted to a summing up and look ahead.
