Abstract A procedure for the determination of Cd, Pb
and Cu in different wine samples after simple sample
preparation on a mercury film electrode (MFE) by potentiometric
stripping analysis (PSA) is presented. In 150
German wine samples collected in 1993/94 the following
values were found: Cd mean: 0.63 ng/mL (range: 0.003–
0.98 ng/mL); Pb mean: 50 ng/mL (range: 4–254 ng/mL);
Cu mean: 250 ng/mL (range: 50–394 ng/mL).
