Samples including organotin contaminated lard, urine, blood, and main organs of the poisoned bodies were collected in the incident which took place in Longnan and Dingnan counties, Jiangxi Province, China around the new year’s day of 1999. The organotin compounds in these samples were identified and determined by gas chromatography-flame photometric detector (GCFPD), gas chromatography-mass spectroscopy (GC-MS) and inductively coupled plasma- mass spectroscopy (ICP-MS). Experiments confirmed that tri- and dimethyltin are the main components that caused the poisoning accident. Monomethyltin, dioctyltin and inorganic tin were also found in several samples.
