The Distribution of Diatom in the Five Lakes along the Yangtze River

Abstract:

In order to investigate the diatom distribution in the five lakes along the Yangtze River, and discuss the significance for the diagnosis of drowning. 6 water samples were collected in the five lakes along Yangtze River in June, 2012. Subsequently, The genus and the quantity of the diatoms in the water samples were investigated using scanning electron microscopy (SEM). The result showed us that there was significant difference between the waters sampled from the different sites . These data on diatom distribution are helpful to the diagnosis of the cause of the death as well as to the determination of the drowning site in cases of drowning. Therefore, it is necessary to develop the database of diatoms in more extensive water bodies for the forensic diagnosis of drowning in the future.
