title: [Determination of 3, 4-benzopyrene in spiruline algae produced and treated by various procedures].
abstract: Spirulina algae grow in highly salted natural lakes. Artificial cultivation in tanks with addition of carbon dioxide (natural gas, burned gases) has been studied in order to improve the biosynthesis. A possible 3, 4-benzopyrene (BaP) contamination must be then considered. Several BaP determinations have been performed in batches of algae from bath origins, prepared following different processes (filtration, spray, cylinder drying). BaP contents are very low (2 to 3 ppb) and comparable between batches.
