Marine Microplastics
Sunlight can break down marine plastic into tens of thousands of chemical compounds, study finds
Sunlight was once thought to only fragment plastics in the marine environment into smaller particles that chemically resemble the original material and persist forever. However, scientists more recently have learned that sunlight also chemically transforms plastic into a suite of polymer-, dissolved-, and gas-phased products. Now, a new study finds that this chemical reaction can produce tens of thousands of water-soluble compounds, or formulas.

MPC Research Specialist, Hauke Kite-Powell, has recently been appointed to a National Academies of Sciences, Engineering, and Medicine committee to study U.S. contributions to global ocean plastic waste.
Tenacious citizens take on the plastics industry over an insidious pollutant
Evidence of pellet pollution has been piling up for decades. R. Jude Wilber of the Woods Hole Oceanographic Institution returned to the area and found that pellet concentrations had nearly doubled.
Microplastics & The Textile Industry
The study of marine microplastics is not new. Woods Hole Oceanographic Institution (WHOI) has been conducting research and publishing on this subject since the 1970s. Other organizations have been active as well.
Starting Oct. 1, foam containers for carryout food will be banned throughout Maryland. Not everyone is happy
As the first state in the country to ban foam food containers, Maryland will be a “very good case study,” said Chris Reddy, a scientist at Woods Hole Oceanographic Institution in Massachusetts.
New Sensor to Monitor Microplastics in Cape Cod Canal
An ocean technology company installed a particle sensor Tuesday in the Cape Cod Canal to monitor plankton and potential microplastics.
How Long Does Plastic Persist in the Ocean?
It can be hard to predict the average lifespan of plastics in the ocean when so many different types exist. WHOI chemists Chris Reddy and Collin Ward are working to simplify these predictions

Infographics strive to give us a sense of how long plastic goods will last in the environment. But is this information reliable? The findings of a new study from WHOI may surprise you.

“We have an opportunity now, where there is public awareness,” said Mark Hahn, a senior scientist at the Woods Hole Oceanographic Institution. “They (plastics) don’t belong there (in the ocean).”
Microplastics research needs innovation, health focus
“Studying microplastics is hard because [they are] not a single contaminant like lead or a uniform contaminant like PCBs [polychlorinated biphenyls],” said NIEHS grantee Mark Hahn, Ph.D., a senior scientist at Woods Hole Oceanographic Institution. “It is a diverse and complex mixture of materials.”
How Big Oil and Big Soda kept a global environmental calamity a secret for decades
The threat to human health is complex and poorly understood. “There are a lot more questions than answers at this point,” says Mark Hahn, a toxicologist at WHOI who studies microplastics.

October 15, 2019 – Watch this recorded public event entitled Microplastics in the Ocean: Emergency of Exaggeration? with a keynote presentation by Dr. Kara Lavender Law on the science of ocean plastic pollution and laying the foundation for solutions.
Dr. Law is a faculty member at Sea Education Association, where she studies the distribution of plastic marine debris driven by ocean physics and the degradation and ultimate fate of plastics in the ocean.
Keynote presentation is followed by a panel discussion on the international perspectives on marine microplastics research moderated by Dr. Heather Goldstone, host of Living Lab, WCAI, Cape & Islands NPR. Panelists include:
Dr. Chelsea Rochman
University of Toronto, Canada
Dr. Hauke Kite-Powell
Woods Hole Oceanographic Institution, U.S.A.
Dr. Gunnar Gerdts

A major component of ocean pollution is less devastating and more manageable than usually portrayed.
Study: Styrofoam Might Last Only Decades, Not Millennia, in the Ocean
Researchers from MIT and the Woods Hole Oceanographic Institution say that sunlight can break down polystyrene within a few decades.
In the Sea, Not All Plastic Lasts Forever
Polystyrene, a common ocean pollutant, decomposes in sunlight much faster than thought, a new study finds.
Sunlight degrades polystyrene faster than expected
The general consensus of governmental agencies is that it takes polystyrene thousands of years to fully break down. But a new study shows that it may instead degrade in decades or centuries when exposed to sunlight.
