Fluoride Action Network


160 cases of acute sodium silicon fluoride poisoning due to accidental intake are reported in this paper. Owing to the great amount of the chemical taken, the onset was abrupt and the digestive symptoms were prominent and severe. Twelve cases had acute gastritis or acute ulceration as shown by gastroscopy. The cardiovascular findings were notable. Ninety-six cases had abnormal electro-cardiographic findings. Abnormal heart rhythm and S-T segment changes were the main findings. These changes were positively correlated with the toxin amount of fluoride. Two cases died from sudden arrest of heart beat. Lung, kidney, liver, and brain functions were also impaired. The authors suggested diagnostic criteria and control procedures.
