Abstract: Human exposure to Cu, Zn and As from drinking water in Beijing, China was estimated in winter. Cu, Zn and As were detected at 6.1, 400 and 0.6 µg/L on average in stagnant water, significantly different from those in the actually ingested boiled tap water, 5.1, 130 and 2.4 µg/L, respectively. Daily intake of Cu, Zn and As from drinking water was 0.8%, 7.7% and 28.5% of the minimum for adults recommended by WHO and varied among different age groups, as the highest occurred in the 64-year-old group, followed by the 20-64-year-old group.
