Yesterday I received an email from Brian Naess. Brian teaches a coral reef ecology class at the University of North Carolina at Chapel Hill and is a frequent St. John visitor. Each Spring Break, Brian takes students to the island to snorkel and study the reefs. Knowing that a lot of you read this blog daily (and a big thank you to all of you who do), Brian asked me to pass along a message regarding the sunscreens we’re using and the types we should use. Here’s what he wrote:
A brand new study has shown how dangerous the chemical oxybenzone is to coral. Oxybenzone is a chemical found in most of the sunscreens out there, and has been shown to damage the DNA and act as an endocrine disrupter of coral. Oxybenzone has also been shown to induce coral bleaching.
“The study discovered that the arguably lowest concentration to see a toxicity effect was as low as 62 parts per trillion – equivalent to a drop of water in six and a half Olympic-sized swimming pools. The highest concentration of oxybenzone was seen in Trunk Bay in the Virgin Islands National Park at 1.4 parts per million. The average concentration for other Virgin Islands National Park coral reef locations was about 250 parts per billion.”
We need to get your readers to switch to sunscreens that don’t have oxybenzone in them.
Most of the zinc/titanium oxide sunscreens should be fine. This is a good resource for people who want to find good sunscreens: http://www.ewg.org/2015sunscreen/
Most people don’t like the zinc/titanium oxide sunscreens, ’cause they are sunblocks and stay on top of your skin. So, when you get out of the water, you look all white! I totally sympathize with that. Unfortunately, the US is way behind the curve on sunscreens. There are many European brands that offer better sun protection in a formula that absorbs into your skin, goes on clear, and isn’t greasy. They are really expensive, though (sometimes around $30 for a small bottle!), and usually not available in the US. There’s a long story behind the regulation of sunscreen in the US…
The best solution is to limit the amount of sunscreen that you apply in the first place by wearing clothing while you swim. Rashguards, wet suits, and dive skins all offer good sun protection without having to goop up before you get into the water.
So I was curious about how reef-safe the sunscreen I use daily is. And sadly, it’s one of the worst ones. Here’s a list of the worst offenders according to the Environmental Working Group:
