Abstract
Abstract Contamination of Pallanza Bay, Lake Maggiore, by mercury from effluents of a chlor‐alkali plant has been observed since the early seventies. The present study attempts to combine our earlier sediment‐associated mercury distribution mapping concept, based on grab samples, with the analysis of sediment core samples. On the basis of the 137 Cs distribution along a core it can be estimated that the sedimentation rate roughly corresponds to 15 mm uncompacted sediments per year. Thus, analysing strata of 4 cm each, the mercury deposition history of the last 10–20 years was visualized, and a net tendency towards decrease of mercury deposition rates observed.
