Abstract
In this study, in the spring of 2019, algaes of Ulva species were collected from eigh station in Giresun costline (Piraziz port, Bulancak port, Giresun port, Keşap station, Espiye-Opet stations, Tirebolu station, Görele station and Eynesil station in May. They are brought to the laboratory in polyethylene bottles. In general, the amount of seaweed samples to be tested was weighed around 15-20 g. Wet algae samples are extracted by methanol solutions with Soxhlet apparatus for 12 hours. By applying the necessary purification processes to the obtained solution, the concentrations of 16 PAH components were determined with the GC/MS device. The amount of most of the 16 PAH compounds in the Keşap site seaweed samples was the highest. The highest amount compounds are found to fluorene, phenanthrene and antresen, and it is high in Bulancak, Giresun-Liman and Keşap sites. It belongs to seaweed samples collected from Piraziz site, which has the lowest values among eight stations. Since the benzo [g, h, i] perylene is lower than the detection levels in many stations. The main origins of PAHs were found as both pyrolytic and petrogenic at most stations.
