Leading ocean advocacy groups join forces to tackle microfiber pollution

Two leading clean ocean advocacy groups have joined forces to stop tiny synthetic clothing fibers from polluting the world’s waterways and poisoning the food chain.


Plastic Soup Foundation (PSF), a Dutch nonprofit, and New York-based Parley for the Oceans announced Tuesday a partnership to tackle the issue of microfiber pollution and to create a global alliance of companies, governments, NGOs and scientists. Microfibers – tiny, often synthetic threads shed from laundry, industrial clothing manufacturing and fishing nets – have been found in alarming numbers in recent studies of microplastic pollution.


“Microfibers pose a massive and complex threat,” said Cyrill Gutsch, founder of Parley for the Oceans, in a statement. “It’s all about funding, supporting and boosting new technologies… [and] the best way to achieve this is together.”


The partnership comes after PSF launched its Ocean Clean Wash campaign earlier this year to educate washing machine manufacturers, fashion brands, environmental organizations and the public about the problem. PSF says already 100 nonprofits and other organizations have signed on to support the campaign, including Greenpeace UK and Austria, Plastic Pollution Coalition and Fauna & Flora International.


A June study found that synthetic fleece jackets release, on average, 1.7 grams of microfibers each wash. These small fibers aren’t easily filtered out at local wastewater treatment plants. The study, funded by outdoor clothing company Patagonia, found that up to 40% of these small fibers land up in oceans, rivers and lakes, threatening wildlife and ultimately our food chain.


Synthetic fibers such as acrylic, polyester and nylon pose the most danger because they don’t disintegrate and disappear over time. Instead, they break down into smaller, increasingly toxic pieces, allowing them to be consumed by fish and other animals. These tiny fibers have the potential to build up and lead to a potentially poisonous accumulation of chemicals in larger species. A study from the University of Exeter found that crabs contaminated with microfibers ate less food and that the polypropylene plastic broke into smaller pieces when ingested, leading to a greater spread in the body – and consequently a greater threat to human health.


Clothing companies have been slow to lend their support to the issue, although that’s starting to change. Patagonia says it continues to fund research and provide grants to explore ways to reduce the release of microfibers into waterways. Dutch clothing brand G-Star Raw announced earlier this year it was supporting PSF to raise awareness among fashion and textile companies about the damage their clothing can pose to the environment and to public health. According to PSF, nearly 40 fashion brands have agreed to collaborate as part of the partnership with Parley. The brands involved will be announced during a Call to Action event early next year.


PSF and Parley will work with other organizations to launch a competition next year to encourage scientists, inventors and clothing makers to come up with ways to stop the release of microfibers in the wash. The winners will be announced in 2018, and will receive a cash prize to implement their ideas.


According to PSF and Parley, possible solutions to the issue include a mechanical filter in washing machines to catch tiny fibers, synthetic yarns and fabrics that don’t release fibers in the wash and environmentally safe coatings that prevent microfibers from releasing when rinsed.

Rethink Your Water: Deep Ocean Water Rehydrates Better, Faster

The ocean. Probably not where your mind goes when thinking of an infinitely renewable drinking water source. The ocean contains salt water, which isn’t suitable for drinking, right?


As it turns out, there’s a unique kind of ocean water that is ideal for drinking: deep ocean water. Desalinated deep ocean mineral water is naturally pure, and a robust source of naturally occurring minerals and electrolytes, which are essential for our bodies’ everyday functions, especially when it comes to hydration.


You may already know there is a direct correlation between hydration status and exercise performance. As you become more dehydrated, your performance declines, including decreased endurance, and muscle tightening and cramping. Now imagine adding heat stress into your exercise routine. Heat stress, coupled with exercise-induced dehydration, aggravates performance decline.


A recent human hydration study conducted at the University of Arizona, in which my colleagues and I evaluated the impact of post-exercise hydration on student athletes, revealed that desalinated deep ocean mineral water not only rehydrated participants twice as fast compared to a carbohydrate-based sports drink or mountain spring water, but also significantly improved recovery of lower body muscle performance. Even though the carbohydrate-based drink contains a larger amount of minerals and electrolytes, we attribute deep ocean water’s greater impact on rehydration and muscle recovery to its unique blend of these materials, not their quantity.


To measure the impact of each liquid’s rehydrating properties, we asked well-hydrated student athletes to exercise on a stationary bike surrounded by heat lamps until they lost 3% of their starting body weight due to dehydration (that’s a 3-5 lb. water weight loss for a 150 lb. person). This typically took about an hour for men, and slightly longer for women, to achieve. The participants then received desalinated deep ocean water, mountain spring water or a carbohydrate-based sports drink for rehydration. We tested their salivary osmolality, a biomarker measuring the rate of rehydration through saliva, as well as the performance of their lower body muscles.


Although many studies have tested the ability of sports drinks to help exercise performance and recovery, our study was the first to compare deep ocean water’s  potential for rehydration after exercise against other fluids. We felt it was critical put participants into a controlled environment, and empirically measure hydration status and exercise performance.


The deep ocean water used in our study comes from the Global Conveyor Belt, a deep ocean current comprised of melted glacial water that travels the depths of the world’s ocean, collecting a natural balance, and specific blend, of minerals and electrolytes not found in any other hydrating beverage. This particular blend is unique because of where the water is sourced, 3,000 feet below the ocean’s surface off the coast of Kona, HI.


More studies are on the horizon to explore deep ocean water and its properties on rehydration, mental capacity and beyond.


This study was supported by an Independent Science Award from the National Institutes of Health (NIH) to Dr. John P. Konhilas. The deep ocean water used in the study was Kona Deep, the first of the new category of deep ocean water now available for consumption in the continental US.
