Contribution to the determination of the place of death by drowning - A study of diatoms' biodiversity in Douro river estuary

The importance of the creation of a diatom database of the potential drowning places (e.g., rivers, seas, lakes) becomes clear in this study. It also shows that, in cases of drowning, the collection of a water sample from the drowning place is crucial. This is the only way to allow a rigorous comparison of the diatom species in water and biological samples.
