Lead exposure from lead crystal.

In a study of the elution of lead (Pb) from crystal decanters and glasses, port containing 89 micrograms Pb/l was placed in decanters and the Pb content of the wine rose steadily to 3518 micrograms/l after 4 months. Wines and spirits stored in crystal decanters for a long time contained Pb at concentrations up to 21,530 micrograms/l. In a short-term experiment white wine eluted small amounts of Pb from crystal glasses within minutes.
