The Shark in the Pool
Plastic fragments, hiding in plain sight,
in a “plastic soup”
Wastewater and Its Contributions to Plastics in the Marine Environment
Common marine debris items includes
things like cigarette butts, cans, plastic
bags and bottles, Styrofoam, balloons,
lighters, and toothbrushes.
Discarded or lost fishing gear such as lines, nets
and buoys are especially dangerous
to sea life.
Hundreds of kilometers off the coast of
southern California lies the Great Pacific
Garbage Patch, a vast soup of degraded
plastic fragments.
Plastic pollution isn’t just a North Pacific
phenomenon but rather a global
problem with global implications for On the other side of the

Where’s it coming from?
18 beaches

6 continents
all contaminated with microplastics
An important source of microplastic
appears to be through sewage
contaminated by fibers from washing
clothes.
Nearly 2000 polyester fibers can float
away, unseen, from a single fleece
sweater in one wash cycle, a new
study reports.

80% of those filaments were
made of polyester or acrylic

What is the solution?

With disposability comes litter.

It’s a “People Problem”.

Notas do Editor

  1. <<Stretch shark to size>>Tonight, I’m going to talk to you about the shark in the pool. Weeellll, there really isn’t a shark in the pool, but the analogy is similar. Sea captain Charles Moore discovered what has become to be known as the “Great Pacific Garbage Patch” quite by chance halfway home to Long Beach from Hawai’i in 1997.
  2. <<Stretch photo to size>> “The ocean is the largest habitat on earth, home to more than twice the number of species found on land. We’re drawn to the ocean, pay premiums for houses near it, restore our spirits on its shores, …” From consumption, to ingestion, I’ll tell you what’s happening. A thousand miles from land, Captain Moore came across an immense section of the northeastern Pacific Ocean that was littered with buoyant plastic scraps. And he’s gone on to tell his story to the world, as author of “Plastic Ocean”, and ocean researcher.He said “I think a plastic garbage patch in the middle of the Pacific screams harm just by being there. Plastic garbage does not belong in the ocean any more than sharks belong in municipal swimming pools.” –Plastic Ocean, 2011(Feel free to stretch the photo as background)
  3. So how does the plastic get there? Our consumption of “stuff”. We live in a throwaway culture. And not all of it ends up in the landfills.
  4. What happens to our consumed materials – they become “trash”, “litter”, “pollution” in our environment – extending from land-based sources to our oceans.
  5. The stuff consumed and littered on land could end up far from where we think. The amount of plastic produced globally and discarded in the U.S.alonehas grown, and presumably some of it winds up in the ocean. Allowed to circulate in the various gyres of the world’s waters. Developing countries?
  6. Accumulation – in the environment and in marine life. Plastic might disintegrate into pieces too small to be caught in a net. Or algae-coated pieces might sink to the sediments - plastic could be eaten by plankton or fish.
  7. Larger bits gradually break down into microscopic fragments - “microplastics”. Minute plastic fibers have turned up in treated sewage and on beaches. Researchers on six continents scooped sand from 18 beaches – separated plastic. A chemical analysis showed that nearly 80% of those filaments were made of polyester or acrylic, compounds common in textiles. (Mark Browne of University College Dublin)Not a single beach was free of the colorful synthetic lint. Each cup (250 ml) of sand contained at least two fibers and as many as 31. The most contaminated samples came from areas with the highest human population density, suggesting that our cities are an important source of the lint.
  8. Science is beginning to ask the question: do chemicals such as PCBs and DDTs that sorb onto plastics then get into the tissues and blood of the animals that eat the plastic? Do these chemicals work their way up the food chain, becoming increasingly concentrated and potentially entering our bodies when we eat seafood? These plastic fibers could "end up on our dinner plates," incorporated into seafood. (Browne) (Credit to Surfrider Rise Above Plastics campaign for the photo of “sushi”.)
  9. This depicts an ongoing study since 1986 in which students on research sailing trips out of Massachusetts have been documenting plastic snagged in their plankton nets in the western North Atlantic Ocean and Caribbean Sea. The team reported recently that it found plastic in more than 60% of more than 6000 tows over 22 years. The levels are low close to shore but rise hundreds of kilometers off the coast between 22 and 38 degrees latitude (roughly from the Bahamas to Baltimore).

  10. Sewage wastewater has been shown to contain microplastic particles or fibers. But it was also in sediment analyzed from beaches in the U.K. near sewage disposal sites – sediment had 250% more microplastic fibers than beaches further from disposal sites, even though sewage had not actually been discharged at the disposal sites for >decade. Browne, M.A., Crump, P.,Niven, S.J. et al. (2011) Accumulation of Microplastic on Shorelines Worldwide: Sources and Sinks. Environmental Science & Technology. 45. 9175-9179.
  11. These microplastic filaments were <5 mm in size. A relatively simple way – control them is at their source, with (click) lint traps for the washing machines, similar in nature to those used for our dryers.
  12. How did synthetic lint get into sewage in the first place? Researcherspurchased a pile of polyester blankets, fleeces, and shirts and commandeered three volunteers' home washing machines for several months. They collected the wastewater from the machines and filtered it to recover the lint. Eachpolyester item shed hundreds of fibers per washing, the team reported.

  14. We need to address the source of the problem – whether it’s the manufacturer, the type of material used for clothing, filters in wastewater including washing machines … it’s really on US, and what we choose to do. Textile manufacturers can help by making garments that shed less lint. The newer HE washing machines don’t have agitators, so wear on clothing that produces lint is greatly reduced. Putting filters to trap the fibers on all washing machines might help. Sewage treatment plants could address – but many of the older treatment plants use clarification of wastewater – that doesn’t work on plastics – relies on densities, which are very similar to water. Coagulation and flocculation also won’t work because plastic has no net charge – so it doesn’t react with the agents. Ultrafiltration is an answer, but not the best – because lots of energy is required to filter the water. Retrofit issues involved for older treatment plants. And there is the enormous amount of energy needed for ultrafiltration.
  15. More cleanups? More education – certainly – But more important, let’s address our consumption through our consumerism. Let’s reduce our personal use of disposable plastics whenever possible. Do you really need a straw? What about using reusable bags for shopping? Let’s ask our favorite restaurants to eliminate Styrofoam from their facility. And use a refillable water bottle – why would you pay more for water than you do gasoline?

Judith Marquez, Innovare Environmental, is working with restaurants and food service establishments to ensure proper disposal of used cooking grease (FOG) to prevent pollution to the environment and protect water quality. She is also working on projects with the Algalita Marine Research Institute to reduce plastic pollution in the environment through research and collaboration with agencies and the general public.
