Alimentary lead intake of adults in Thuringia/Germany determined with the duplicate portion technique

The daily lead intake in Germany in 1996 was studied using the duplicate portion technique. The study was carried out in four towns in Thuringia (Jena, Ronneburg, Rositz, Steudnitz), in which volunteers collected all foods and beverages over 7 consecutive days. The mean lead content of consumed food and beverages was 66 and 55 microg/kg dry matter for women and men, respectively; the average lead intake was 19 microg/day for both, women and men. In relation to body weight (b.w.) the intake for women was 283 ng/kg and for men 242 ng/kg b.w. These values are well below the WHO limit. An oral lead exposure of the adult population of Thuringia/Germany can be excluded.
