Stable nitrogen isotope ratios of particulate matter POM, zooplankton and selected biota such as Mytilus galloprovincialis were used to assess the impact of anthropogenically derived organic matter from untreated domestic sewage, municipal and industrial effl uents on the coastal ecosystem of Kosirina Bay (Murter Island). The differences in δ 15 N values observed in POM and organisms collected in Kosirina Bay were compared to POM and biota sampled at unaffected sites from the southern part of
