Daily intakes of copper, zinc and arsenic in drinking water by population of Shanghai, China (Journal article)
Xu, P./ Huang, S. B./ Wang, Z. J./ Lagos, G.
Daily intakes of metals in drinking water are of extreme importance in risk assessment to human health. Some papers focused on this topic, but most of them did not consider the effect of age, gender and work location on daily intakes of metals in drinking water. The objective of present paper is to estimate the levels of Cu, Zn and As ingestion in drinking water in Shanghai, China and the effect of age, gender and work location on daily intakes of these metals. It was also the first time that such a detailed investigation on daily intakes of metals in drinking water was carried out in China in recent years. Drink/Sample (D/S) method was used to estimate the daily intakes of Cu, Zn and As in drinking water. The mean concentrations of Cu, Zn and As in drinking water were 10.8 mu g/l, 0.29 mg/I and 0.91 mu g/l, which were lower than U.S. EPA's Drinking Water Equivalent Level (DWEL) and WHO guideline values. The average daily intakes of Cu, Zn and As in drinking water was 21.12 mu g/d, 0.65 mg/d, and 1.83 mu g/d, which were on average 0.01%, 1.1% and 1.5% of the provisional maximum tolerable daily intake (PMTDI) set by the Joint FAO/WHO Expert Committee. There was a significant difference in daily intake of Zn for different work locations (P = 0.04). But no other significant differences in daily intakes of metals in drinking water were found according to age, gender and work location. (c) 2005 Elsevier B.V. All rights reserved.
