A simple and rapid method is described for processing organ and water samples for the identification of diatoms so that they can be studied and recorded for taxonomic and diagnostic purposes. Samples are treated with concentrated nitric acid; the fluid obtained is centrifuged, and its sediment is dried, coated, and examined under the scanning electron microscope. The method does not alter the morphology of diatoms and allows the study of freshwater and seawater species present in the organs of bodies found in the water, making possible the diagnosis of drowning under specific conditions.
描述了一种简单快速的方法,用于处理器官和水样以鉴定硅藻,以便出于分类学和诊断目的对其进行研究和记录。样品用浓硝酸处理;将所得液体离心,其沉淀物干燥、镀膜并在扫描电子显微镜下检查。该方法不会改变硅藻的形态,并允许研究水中发现的尸体器官中存在的淡水和海水物种,从而有可能在特定条件下诊断溺水情况。
