With the three-year hard work of all research memebers, we have made some significant progress：（1） Established a low cost, rapid while sensitive sensor and detector for halogenated alkanes. In this study, sensing material with high fluorescene yield for halogenated alkanes detecting were designed and synthsized. The fluorescene intensity, stability and sensitiviety of synthsized sensors were improved by using the evanescent wave effect of nanowile arrays.This study realized the measurement of weak scence signals, and developed a portable fluorescent detector for trace halogenated alkanes.（2）Prepaed an electrochemical luminescence immune detector. The microplate electrodes were designed, the immune agents were coated on the electrodes, the immunation reactions of test samples were occurred within the wells of microplate, and the electrochemical signal of each well was measured and recorded.（3） Synthesized a fluorescent immune sensor. A huge array reaction area was formed on a tiny matrix material, the immunation reaction and fiuorescene signal record in each reaction area was respectively performed. A high-through, rapid and minimized fluorescence immune sensor was developed.（4）Prepared a DNA damage detector. The detecting instrument of capillary electrophoresis-on site laser induced fluorescence polarization was papared, and the method for DNA damage analysis was developed as well.（5） Developed whole cell biosensing fluorescene detectors for heavy metals and benzenes detection. Based on the induction effect of heavy metals and benzenes on microbial whole cell biosesnors, measured the activity intensity of the firefly luciferase expressed by host bacterium, combined the software for data calculation, developed a set of bacterial whole cell biosensing fluorescent detectors for heavy metals and benzenes analysis.（6） Established a set of assistant emergency monitroing system for contaminants released from the sudden environmental pollution accidents. The assistant system composed of three modules including physicochemical database for common chemicals, a rapid and quantitative chormatogram spectra bank, and emergency monitoring assistant information database. The achivements mentioned above will be benefit for rapid identifying of sudden environmental pollution accidents,for rapid detecting of main contaminants, for preparing rapid and effective treatment and deposal strategy to deal with the sudden environmental pollution accidents.
