The Karaburun-Ildır Bay Special Environmental Protected Area (SEPA) is a unique and ecologically significant region located along the Aegean coast of Türkiye. The aim of this study was to determine the total petroleum hydrocarbon levels in seawater and sediment samples collected from stations in Karaburun-Ildır Bay. Sampling was carried out in May and September 2022. The samples were analyzed using a spectrofluorometer (UVF, Shimadzu RF-5301). While the total petroleum hydrocarbon (TPH) levels were determined as 0.10-2.70 µg/l in seawater samples, it was determined as 1.77-42.62 µg/g in sediment samples. TPH values in seawater samples were above the international limit values (UN Environment Programme). While significant difference was detected between stations in the TPH values in the sediment, no significant difference was detected between the sampling. This study is important as it is the first to determine the TPH levels in Karaburun-Ildır Bay. The results showed that it is important to continue monitoring studies in protected areas.
