#### Abstract

To investigate the contamination level and total dietary intake of Hg in common restaurant meals of Seoul area, 125 samples of 5 typical meals were collected and determined for their total Hg contents by flameless atomic absorption sepctrophotometry. The average concentrations of Hg were 0.186ppm in drained residues and 0.007ppm in fluids, in which two samples yeukkye-jang and bibim-bab from two sites showed such a high level of 20-30 times of mean values. The average amount of Hg per meal excluding the two samples was $79.6{\mu}g$ and it was not significantly different among different meals. The daily dietary intake of total Hg from 3 restaurant meals was estimated to be $239{\mu}g$, which was 5 times higher than the FAO/WHO limit of $42.9{\mu}g$.
