Release of lead from crystal decanters under conditions of normal use.
The pattern of release of lead (Pb) from crystal was investigated using new and used decanters.
Two decanters in use prior to this study yielded significantly less Pb into sherry than did a decanter during its initial use.
Pb concentrations in sherry after storage for 2 months reached 50, 163 or 1410 mug/litre in decanters previously used for 20, or for 10 yr, or a new decanter, respectively.
The new decanter imparted progressively less Pb through normal use.
Pb concentration was assayed in sherry during a series of three separate sampling periods, each 2 months in duration.
The Pb concentration at the end of each period was 1410, 330 or 150 mug/litre respectively.
