microplastics

On behalf of the Interagency Marine Debris Coordinating Committee, NOAA’s Marine Debris Program and EPA’s Trash Free Waters Program are pleased to share a draft Report on Microfiber Pollution, which is now available for public comment. Required by law, this report will provide Congress with an overview of the microfiber pollution issue, while also outlining a path forward for federal agencies, in partnership with other stakeholders, to address this problem. We invite comments, feedback, and recommendations on the draft Report on Microfiber Pollution, including Section 7, which contains a plan that outlines opportunities to reduce microfiber pollution.

Plastic particles less than 5mm in size, known as microplastics, are found everywhere that scientists have looked, including in the coastal waters of New England. The eastern oyster is an important commercial aquaculture species that has been shown to eat microplastics. In partnership with the NOAA Marine Debris Program, marine scientists at the University of Connecticut sampled oysters in the field and performed a series of selection experiments in the laboratory to determine what types of microplastics oysters prefer to eat or reject and how that relates to what is in the natural environment.

Spring is here! As the temperatures increase and weather improves, many of us are drawn to the outdoors. But what if your trip to the beach could be more than just an enjoyable day? What if you could do scientific research at the same time as a citizen scientist? Opportunities for the public most often come in the form of data collection, but they can also include providing input on questions to investigate, participating in study design, or interpreting and sharing results. Several projects funded through the NOAA Marine Debris Program have tapped into this community resource as well, and committed stewards around the country have contributed invaluable data to monitoring and research projects that support our vision of a sea free of debris.

Huge amounts of marine debris enter the ocean and Great Lakes every year, from large abandoned and derelict vessels and fishing gear, to plastic bottles, food wrappers, and other trash, and even tiny pieces of plastic that you can’t see with the human eye! But once our trash is in the ocean, what happens to it? How long does it last, and can we ever say that it’s gone?

Millions of tons of debris enter the marine environment each year, including our trash and damaged fishing gear, and can be found at the surface of the water, down to the deepest parts of the ocean. Many marine debris items, especially plastics, are small enough to be ingested, or eaten, by wildlife, an issue of growing concern for the health of hundreds of marine animals. Animals may directly eat marine debris, or it may be consumed with prey that already has a belly full of marine debris.

In the environment, animals may be exposed to many stressors at the same time, such as pollution, overfishing, and disease. Research suggests that animals exposed to microplastics and microfibers, or plastic pieces smaller than 5mm in size, may experience negative impacts to their immune system.

Microplastics, or plastic pieces smaller than 5mm in size, are commonly found in our ocean and coastal waters. Do the microplastics that these larval crabs encounter while drifting in the ocean affect their survival and ability to return to estuaries? With support from a NOAA Marine Debris Program Research grant, a team of University of Delaware marine scientists have joined forces to study this question.
