摘要: Abstract The biotic index Bentix [Simboura, N., Zenetos, A., 2002. Benthic indicators to use in Ecological Quality classification of Mediterranean soft bottom marine ecosystems, including a new index. Mediterr. Mar. Sci., 3 (2), 77–111] developed for the ecological status zoobenthic communities was tested coastal area (Aegean Sea, N. Evvoikos gulf, Greece) subject coarse metalliferous waste discharge. residues form slag are byproducts smelting procedure local ferronickel plant and discharged permitted 8 km from shore. This practice adopted over last 36 years has led formation thick underwater deposit on sea bottom. A decade monitoring resulted long series data macrozoobenthos area. Application other indices revealed long-term impact dumping benthic potential used assess community health. Among tested, succeeded assessing trends decline or recovery proved efficient detecting differences attributed transferring core activity studied, as validated by geophysical provided.
