This paper reports the results of mercury contamination monitoring in the Cecina river basin (Tuscany,Italy). Mercury was measured in the waters, sediments and fish species of the river and its most important tributaries. In fish specimens the organic form was also determined. The results showed high mercury levels in most of the samples analysed. Particularly high concentrations were found in the sediments of the S:Marta canal flowing into the Cecina, where a chlor-alkali plant discharges its wastes, and high levels were still detectable 31 Km downstream from the confluence. Near the S. marta confkluence many fish specimems were very contaminated and a study on Leuciscus cephalus cabeda growth suggetsted that at this site mercury accumulation occurs in these organism since they are very young.

Abstract

This paper reports the results of mercury contamination monitoring in the Cecina river basin (Tuscany,Italy). Mercury was measured in the waters, sediments and fish species of the river and its most important tributaries. In fish specimens the organic form was also determined. The results showed high mercury levels in most of the samples analysed. Particularly high concentrations were found in the sediments of the S:Marta canal flowing into the Cecina, where a chlor-alkali plant discharges its wastes, and high levels were still detectable 31 Km downstream from the confluence. Near the S. marta confkluence many fish specimems were very contaminated and a study on Leuciscus cephalus cabeda growth suggetsted that at this site mercury accumulation occurs in these organism since they are very young.
