An Application of Environmental Magnetism in Environmental Science

Environmental magnetism is chiefly aimed at solving environmental problems.Lots of researches were done and plenty of experience has been gained in reconstructing pollution history,monitoring present environmental pollution,tracing and separating the sources of pollution.With the advantage of fast,sensitive, inexpensive,non-destructive measurement,environmental magnetism can be used as a preliminary method for studying pollution effects before starting time consuming and expensive chemical methods.Principles and pur- poses of the magnetic method were introduced in different environmental systems.It also showed the relation- ship between environmental pollution and meaningful magnetic signals from intensive anthropogenic activities. To further develop,however,new methods must be used to analyse and interpret the magnetic data,and other related subjects must be imported to the environmental magnetism.
