Sunscreens generate a potentially important source of environmental contamination across marine and aquatic systems. Oxybenzone (benzophenone-3; BP-3) is one of the most common organic filters in chemical sunscreen and has been detected in seawater at high concentrations. In this study, we asked whether BP-3 contamination affected the photosynthesis, respiration, and photophysiology of rhodoliths collected offshore from popular Gulf of Mexico beaches in North Florida. We found no evidence for negative effects of the common organic UV filter BP-3 on Gulf of Mexico rhodoliths. This result is promising for the fate of these important algae who act as habitat builders and foundational components of global reef ecosystems.
防晒霜在海洋和水生系统中产生了一个潜在的重要环境污染源。氧苯酮（二苯甲酮-3；BP-3）是化学防晒霜中最常见的有机滤光剂之一，已在高浓度海水中检测到。在这项研究中，我们询问了 BP-3 污染是否会影响从佛罗里达州北部墨西哥湾热门海滩采集的柳珊瑚的光合作用、呼吸作用和光生理。我们没有发现常见的有机紫外线滤光剂 BP-3 对墨西哥湾柳珊瑚有负面影响的证据。对于这些重要藻类的命运来说，这一结果是有希望的，因为它们是栖息地的建设者，也是全球珊瑚礁生态系统的基础组成部分。
