Fatal overdose of the herbicide bentazone.

A 59-year-old woman who intentionally ingested 100-200 ml Basagran was taken to the hospital with a cardiac arrest 2 days after she had consumed the herbicide. During this period she suffered vomiting, urination and diarrhoea and she was drowsy with a muddled speech. Biological samples obtained at the autopsy were analysed and presence of bentazone, alcohol and an active metabolite of citalopram were detected. Blood concentrations of bentazone, alcohol and desmethyl-citalopram were 625 mg/kg, 0.62 g/l and 0.03 mg/kg, respectively.
