Significance of Diatoms in Diagnosis of Drowning Deaths by Ajay Rana in Peer Reviewed Journal of Forensic & Genetic Sciences (PRJFGS) in Lupinepublishers
Diatom
test is an important tool in diagnosis death in drowning cases. As the typical
features of ante-mortem drowning disappeared very rapidly with commencement of
putrefaction and hence diatom test plays an important role for diagnosis and
confirmation of drowning deaths. Diatoms have number of characteristic like
their widespread presence in water, high diversity in species, habitat
specificity and have a good potential for preservation and thus this group can
be used in forensic geosciences for criminal investigations. Extraction and
identification of diatoms present in the tissue samples can be used as
supportive evidence in drowning and also for site specific diatoms. Temperature
and pH variations also play important role in the distribution of diatoms in a
particular location. Diatoms species detection in both water and tissue samples
gave a reliability of the diatom test in solving cases pertaining to drowning
deaths. Hence the possible means and methods must be practiced on a regular
basis by the forensic examiner as well practitioners so that new possibilities
must always be explored for extraction and identification of diatoms in near
future. This paper reviews the recent year’s progress on diatom test and its
application in forensic science.
