Morpho-physiological responses by <i>Chlamydomonas reinhardtii</i> to different concentrations of ibuprofen

Pollution of aquatic bodies by pharmaceutical compounds is an emerging environmental problem because these drugs are extensively used in animal and human medicine. Ibuprofen, 2-[4-(2-methylpropyl)phenyl] propanoic acid, the non-steroidal anti-inflammatory drug mainly present both wastewater rivers lakes Europe. Despite this emergency giving rise a great interest scientific community, literature about effects ibuprofen on microalgae scarce. A previous work freshwater microalga Scenedesmus rubescens had shown some morpho-physiological caused treatment with 62.5, 250 1000 µg L−1 ibuprofen. In paper, we presented results at same concentrations, ranging from levels up to higher values, Chlamydomonas reinhardtii (P.J.L. Dangeard). Ibuprofen alga were assayed through analyses growth curve. Moreover, cell morphology, ultrastructure, photosynthetic pigments performed. The first effect was stimulation growth. addition, following exposure ibuprofen, cells exhibited morphological ultrastructural alterations, latter ones consisting starch granules vacuolar cytoplasmatic inclusions. On contrary, chlorophyll carotenoids amounts, not affected treatment.
