Researchers have identified a mechanism by which oxybenzone – a common sunscreen component – may be hastening the demise of reefs.\u00a0<\/span><\/p>\n Oxybenzone is the sun-blocking agent in many sun creams. Its chemical structure causes it to absorb UV rays, preventing damage to skin cells.<\/span><\/p>\n But it has attracted controversy in recent years after studies reported that it can damage coral reefs.\u00a0<\/span>These concerns have led to some beaches in Hawaii, Palau and the US Virgin Islands, banning oxybenzone-containing sunscreens.\u00a0<\/span><\/p>\n However, the mechanisms by which oxybenzone does harm have largely remained a mystery, making it difficult to ensure that sunscreen components proposed as alternatives are truly safer for corals.<\/span><\/p>\n To find out the mechanism, <\/span>Stanford researchers conducted a study.<\/span><\/p>\n The scientists used sea anemones and mushroom corals as models and exposed them to oxybenzone in a tank filled with artificial seawater.<\/span><\/p>\n In one of the experiments, this treatment was combined with simulated sunlight, which saw all anemones die off within 17 days. In a parallel experiment where there was no sunlight, the creatures all remained viable.\u00a0<\/span><\/p>\n This runs counter to what the scientists expected from oxybenzone which is designed to absorb light energy and dissipate it as heat to prevent sunburn.<\/span><\/p>\n Hence, these findings <\/span>suggest that sunscreen pollution and climate change combined could be a greater threat to coral reefs and other marine habitats.<\/span><\/p>\n Source:\u00a0 <\/b>The post is based on the article <\/span>\u201cCorals and sea anemones turn sunscreen into toxins \u2013 understanding how could help save coral reefs\u201d <\/b>published in<\/span> Down To Earth <\/b>on<\/span> 9th May 2022<\/b><\/p>\n","protected":false},"excerpt":{"rendered":" What is the News?
