Abstract: Objective The forensic application of Lefort aqua regia digestion method detecting diatom in rabbits’s organs. Methods Using the Lefort aqua regia digestion-membrane ifltrition-SEM observation method and the traditional acid digestion-centrifugation-light microscopy observation method to detect diatom of drowning or postmortem immersion rabbits’s organs(lung,liver,kidney), and make statistical analysis of diatom number, consuming time, digestive capability and ifne structure of diatoms. Results The diatom number of Lefort aqua regia digestion method was superior to conventional acid digestion method, with the difference being statistically signiifcant (P<0.05), as well as consuming time, but have undifferentiated of drowning grounp(P>0.05), and have a better observation effect. Conclusion The Lefort aqua regia digestion method for diatom extraction was helpful for diatom identiifcation., and useful in drowning test by conventional and economicly.
