Popis:	Zircons (20–100 mg) are decomposed within 1 h by fusion with potassium hydrogenfluoride followed by fuming with sulphuric acid. With differential-pulse anodic stripping voltammetry, after deposition for 1 min, the limit of detection for lead is 2 ng ml −1 and the limit of quantitation is 6.6 ng ml −1 . Results (7–247 mg kg −1 lead) are reported for nine zircons.
