The increasing amount of marine litter pollution and its impact on the marine environment raises global concern. This study aims to reveal the effect of streams on marine litter density and composition. A total of ten stations on the southeastern Black Sea and six stations on the Manahoz stream were seasonally surveyed.

- The study evaluated the health of fish from specific aquacultures using histopathologic and enzymatic analyses and investigated pollutant levels in fish tissues from juvenile to two-year-old specimens.
- Abnormalities like lipidation and tissue enlargement were noted in fish organs, though they were infrequent; enzyme activity and protein levels were mostly influenced by the fish's age and season rather than farm conditions.
- Metal concentrations in the fish tissues remained within national and international safety limits, suggesting that fish from optimal farming conditions are suitable for human consumption.
Increasing marine traffic, over 55,000 ships visit per year, through the Turkish Straits System and the Sea of Marmara, produces a yearly average of 12 illegal oil discharges. This paper documents the comparison of chemical fingerprints of spilled oil with suspected sources of oils for identifying the source of illegal pollution in Turkey's seas. Fingerprinting is initiated by comparison of the synchronous fluorescence spectra (Δ=20 or 15 nm) of fugitive and suspected source oils.

The total-PAH concentrations, measured by Spectrofluorometry were in the range of 1.16-13.
