Origin of lead in eight central European peat bogs determined from isotope ratios, strengths, and operation times of regional pollution sources

Abstract

Lead originating from coal burning, gasoline burning, and ore smelting was identified in Pb-210-dated profiles through eight peat bogs distributed over an area of 60 000 km(2). The Sphagnum-dominated bogs were located mainly in mountainous regions.
