Direct discharges of domestic and industrialwastewaters to the coastal zone of Aegean Sea are an important concern. Designof an environmental baseline assessment program prior to any coastaldevelopment is a crucial part of the feasibility studies due to the complexityof the coastal dynamics. The backgroundbiogeochemical status of the Nemrut Bay’s water column was set to assess theimpact of a proposed industrial discharge. The seawater samples were collectedon seasonal bases representing winter (mixed water column) and summer(stratified) conditions, and were analyzed for dissolved heavy metals (Hg, Cd,Pb, Cr, Cu, Zn, Mn, Ni, Fe, Mg), dissolved and particulate nutrients (NO3-,NO2-, PO43-, Si, TOC, TPP, POC,PON), dissolved oxygen (DO) and chlorophyll-a (Chl-a) contents. The baselineassessment was based on the Turkish regulatory liabilities. The analyses of thesamples showed that anthropogenic influence is mostly detected in stationscloser to the shoreline. The Nemrut Bay has quite a low level of pollutionregarding the impacts of high intensity of industrial and maritime activitiesin its vicinity are considered.
