JECFA Evaluation
TIN | 2006 | At its present meeting, the Committee reconsidered studies of the acute toxic effects seen in humans after consumption of foods containing high concentrations of inorganic compounds of tin, and also considered a new study. The Committee concluded that the data available indicated that it is inappropriate to establish an ARfD for inorganic tin, since the occurence of GI-irritation afte
