A study on the diagnosis of drowning by examination of lung chlorophyll(a) of planktons with a spectrofluorophotometer.

An investigation on the diagnosis of drowning by analysis of chlorophyll(a) (Chl.(a)) of planktons in the lung sample with a spectrofluorophotometer (SFPM) is reported. The diagnostic criteria or main points of death by drowning are suggested are according to our experimental studies. Meanwhile two cases of submersion in water were investigated and the causes of death were diagnosed correctly. It is concluded that examination of lung Chl.(a) of planktons could be used as a reliable diagnostic method in forensic practice.
