Research interests:
Environmental magnetism is a relatively new science.It essentially grew out of numerous interdisciplinary studies involving Lakes, Marine sediments, Loess, Soils, Biomagnetism, Pollution and Archeology. Detecting the pollution of our environment, expecially latter-day pollution with environmental magnetism method is my major.
Recent studies are magnetic properties of highroad-side pine tree leaves in Beijing and their environmental significance. A series of rock magnetic experiments show that the primary magnetic mineral of leaf samples was identified to be magnetite, in the pseudo-single domain (PSD) grain size range 0.2-5.0 μm. On the other hand, magnetite concentration and grain size in leaves are ascertained to decrease with increasing of sampling distance to highroad asphalt surface, suggesting that high magnetic response to traffic pollution is localized within a distance of some two meters away from highroad asphalt surface. Although magnetic susceptibility is ordinarily regarded as a simple, rapid and low-cost method for monitoring traffic pollution, saturation isothermal remanent magnetization (SIRM) can be treated as a valid proxy for monitoring of air particulate matter (PM) when samples are magnetically weak. We believe that a synthetic rock magnetic study is an effective method for determining concentration and grain size of ferromagnets in the atmospheric PM, and then it should be a rapid and feasible technique for monitoring atmospheric pollution.
Mine hydrogeologic information management and water-disaster prediction system, which is my master's degree paper. Though I don't do this research again, it still is one of my research interestes.
