The sensitivity of mussel-watch programmes to detect temporal trends in the bio-availability of metals. A case study of the Saronicos Gulf of Greece
Abstract
Statistical power analysis has been used to determine the sensitivity of the mussel-watch programme in Hellenic seas, with particular focus placed on the data obtained for metal content in mussels from the Saronicos Gulf during the period 1985–1997. Sample collection was carried out quarterly. Soft tissues of 60–100 similarly sized mussels (Mytilus galloprovincialis) were pooled into six composite samples and analysed by
