Ring test for whole-sediment toxicity assay with -a- benthic marine diatom
Science of The Total Environment, 2010 This work presents the results of an interlaboratory proficiency exercise for whole-sediment toxicity assays with the benthic marine diatom Cylindrotheca closterium. An assay protocol was established and followed by all participating laboratories. Cell growth after 72 h exposure was the endpoint used.

Diatom test: a reliable tool to assess death by drowning?
International Journal of Research in Medical Sciences, 2016 Background: Post mortem analysis of drowning is a classical problem especially in decomposed bodies recovered from water. One of the important issues in the study of drowning has been the search for a sensitive, specific and easily applicable test for the cause of death.

Characterization of drowning by diatom test.
The Indian journal of medical research, 1993 Examination by the diatom test, of different organs of corpses of individuals who died of drowning revealed the presence of frustules in all the visceral organs. Diatom load of different organs was found to be positively related with breadth/diameter of the frustule. Relatively larger diatoms were encountered in the lungs, heart and kidneys as compared

[Progress on Diatom Test in Drowning Cases].
Fa yi xue za zhi, 2016 In drowning cases, it is difficult to judge whether the deceased died from drowning or throwing into the water after killed or identificate the cause of death of the decomposed corps in forensic practices. The diatom test is still considered as the important assistant evidence in drowning cases.
