  • GOOP OF DEATHChemicals from sunscreen are poisoning the ocean

    Sunscreen has changed the lives of beach bums everywhere, allowing them to laze longer in the sun without their skin baking into a ruddy crisp. And it’s most likely made them safer, protecting them from the ultraviolet radiation that causes nearly nine-tenths of cases of skin cancer.


    +
    But the same chemical compounds that are helping people live longer, sunnier lives are hurting the ocean. A new study published in Environmental Science & Technology found that when slathered-up beachgoers go for a dip, the traces of sunscreen that wash off into the ocean poison phytoplankton, the microscopic plant life that anchor the marine food web.


    +
    To conduct their study, scientists hit Palmira beach on Spain’s Majorca Island, which sits on a strip of the Mediterranean that attracts 200 million tourists a year. They found that by noon on hot August days, hydrogen peroxide concentrations in the seawater surged to nearly three times what they had been at dawn. Lab testing confirmed that under the glare of UV rays, particles of two common ingredients of sunscreen—titanium dioxide and zinc oxide—convert into hydrogen peroxide in similar volumes.


    +
    Here’s the problem: at those levels, hydrogen peroxide is so toxic to phytoplankton that it caused their numbers to crash by around 80%. These tiny single-cell plants function as the ocean’s salad bar, giving life to the entire marine ecosystem. Shrimp, for example, chow down on phytoplankton, and in turn become dinner for everything from squid and seals to penguins and whales.


    +
    Not only are phytoplankton a crucial part of a balanced ecosystem, they also perform a critical role in the Earth’s carbon cycle. Like land plants, phytoplankton get their energy by photosynthesis—swapping carbon dioxide in seawater for oxygen. This lets the sea absorb carbon dioxide from the atmosphere, stalling the effects of burning fossil fuels on air temperatures.

  • Save the plankton, dont use commercial sunscreen! Between the nano particulates and other nasty ingredients..  seriously though, I remember reading about how the plankton play a bigger role in c02 absorption then the rain forests... gotta double check that though

  • This blows.  I just got rid of my sunscreens that had avobenzone in favor of titanium/zinc oxide ones......
    The sea was angry that day, my friends--like an old man trying to send back soup in a deli.

  • Here we are once again showing that the toxic poison to the planet is mankind. Eliminate mankind, and this world would be a better place.  ;)


    On a serious note, sunscreens aren't just toxic to phytoplankton, outside of the ones that are killing the plankton, they're pretty damn toxic to us.

  • Amen.  I use either Raw Elements or Badger... both work great and stay on for a long time.

    On a side note, some of the names of the healthy sunscreens look like titles of soft-core hippie porn.

  • Thanks for the info. So, what's the alternative? I make my own with Shea butter and zinc powder... But the zinc has an impact. So... I tried getting a stocking and putting that on my head like I thought I saw a guy in bondi do once... Didn't work.. Couldn't breath or see... Need a thinner material

  • I play a lot of golf and my home course had to send an email to the members to not use the spray on sunscreen anywhere on the course.  You have to apply it in the parking lot.  The stuff instantly kills the grass.  I came across one of the spots where someone had applied it on the course.  You could clearly see the persons footprints because the grass under the person's feet was protected and remained healthy and there was a 4 foot diameter circle of dead and dying grass from where the person had sprayed their legs.  Amazing.  Imagine what that stuff is doing to you when you spray it directly on yourself and its absorbed into your bloodstream.


    Found a picture on the web......what I saw on my course was just like this.

    Hmmm….blue…I wonder if the stuff blue man group uses is waterproof. If so, I might try it - certainly no one will be able to drop in on me and say they didn't see me.  ::) 8)

  • I'm not sure that this is something worth worrying about. Cancer and melanoma is worse and there are already a lot of sustainable sunscreens.
