This paper describes isolation and indentification of HHCP (Galaxolide (R)) as pollutant in red alga Laurencia pyramidalis Bory de Saint-Vincent ex Kutzing (Syn. Laurencia obtusa var. pyramidata Bory ex J. Agardh) collected from Igneada (Black Sea coast) by GC/MS analysis. It was previously found as a pollutant in Danube River which consequently contaminates the Black Sea. It was suggested that this is a contamination of alga because it was not found in the same species collected from Assos (Canakkale). This is the first record of HHCP contamination in algae.
