Abstract
This study was conducted to examine the contents of heavy metals in beverages and to estimate their intakes. The contents of lead (Pb), cadmium (Cd), arsenic (As), and tin (Sn) were determined in a total of 207 samples of beverages using atomic absorption spectrophotometer(AAS) and inductively coupled plasma spectrometer(ICP). Also a mercury analyzer was utilized for analysis of mercury. The values of heavy metals in beverages were as follows [min-max (mean), mg/kg]; Hg 0.0001-0.0025 (0.0004), As ND-0.0245 (0.0003), Pb ND-0.089 (0.004), Cd ND-0.006 (0.001), Sn ND-45.36 (1.97). Our results were similar to those reported by other countries. Our weekly intakes of heavy metals from beverages take $0.01%{\sim}0.06%$ of PTWI (Provisional Tolerable Weekly Intake) established by FAO/WHO.
