Istanbul University, Institute of Marine Sciences and Management, Vefa, İstanbul, Turkey Volatile hydrocarbons were investigated in 14 marine algae collected in the Black Sea, Dardanelles and Aegean Sea. The algae were extracted with dichloromethan in Soxhlet for 8 h. The extracts were distilled and the volatile compounds of the residue were separated by steam distillation. The distillates were extracted for ether and distilled. The residue analyzed by Gas chromatography/Mass Spectrophotometry (GC/MS). The identified substances are: in aliphatic group: 19 linear, 20 branched, 19 cyclic alkenes, 18 alkenes, 2 alcohols, 12 aliphatic aldehydes, 2 ketones, on aromatic group: 31 mono ring, 16 naphthalene derivatives, 4 indan derivatives, 2 three rings and three sulfur containing aromatic compounds. Additionally 1 aromatic aldehyde, phenyl alkene derivative were identified. The Pristane/Phytane (Pr/Ph) ratio and the compounds mentioned above inadequate the oil contamination of algae. Comparison of the data published since 1960 with our results shows that the numbers of detected oil compounds are increasing. The anomalous on the hydrocarbons detected in algae can be attributed to oil contamination. Besides these oil compounds (Exogenic), some toxic compounds as phthalates and nonyl phenol were detected in algae sample. The latter compound is originated from degradation of non ionic surfactant. The all oil compound identified in algae were originated from the oil pollution. The origin of some alkenes, aldehydes, alcohols are suspect. These findings show that the algae can be used as indicator in sea water pollution. Keywords : MARINE ALGAE, VOLATILE HYDROCARBONS, GC/MS
