A study, published Tuesday in the Archives of Environmental Contamination and Toxicology, concluded that the chemical oxybenzone, an ingredient that protects humans against the effects of ultraviolet light (a.k.a. sunburn), also breaks down coral cells by leaching it of nutrients and eventually turning it white.
The study, called Toxicopathological Effects of the Sunscreen UV Filter, Oxybenzone (Benzophenone-3), on Coral Planulae and Cultured Primary Cells and Its Environmental Contamination in Hawaii and the U.S. Virgin Islands, examined the effects of oxybenzone on coral and its toxicity in coral cells from the larval form of the coral.
Oxybenzone has been of emerging concern, especially in areas populated by swimmers, boaters and beachgoers. According to Buzzfeed News, it was found in the highest concentrations in coral reefs popular with tourists, particularly in Hawaii and the U.S. Virgin Islands, where the study was conducted.
The news is prompting calls for replacing sunscreen with protective clothing like hats, loose-fitting, long-sleeved shirt and long pants or wetsuits while in the water.
