25% of Fish Sold at Markets Contain Plastic or Man-Made Debris

Roughly a quarter of the fish sampled from fish markets in California and Indonesia contained man-made debris—plastic or fibrous material—in their guts, according to a study from the University of California, Davis and Hasanuddin University in Indonesia.

The study, published last week in the journal Scientific Reports, is one of the first to directly link plastic and man-made debris to the fish on consumers’ dinner plates.

“It’s interesting that there isn’t a big difference in the amount of debris in the fish from each location, but in the type—plastic or fiber,” said lead author Chelsea Rochman, a David H. Smith postdoctoral fellow in the Aquatic Health Program at the UC Davis School of Veterinary Medicine. “We think the type of debris in the fish is driven by differences in local waste management.”

"Waiter, There’s Some Plastic in My Fish"

The researchers sampled 76 fish from markets in Makassar, Indonesia and 64 from Half Moon Bay and Princeton in California. All of the fragments recovered from fish in Indonesia were plastic. In contrast, 80 percent of the debris found in California fish was fibers, whereas not a single strand of fiber was found in Indonesian fish.

Indonesia has little in the way of landfills, waste collection or recycling and large amounts of plastic are tossed onto the beaches and into the ocean. The problem is made worse by a lack of purified drinking water that forces its residents to drink bottled water.

“Indonesia has some of the highest marine life richness and biodiversity on Earth and its coastal regions—mangroves, coral reefs and their beaches—are just awash in debris,” said co-author Susan Williams, a professor with the UC Davis Bodega Marine Laboratory who has worked on projects in Indonesia for the past several years. “You have the best and the worst situation right in front of you in Indonesia.”

Meanwhile, the U.S. has highly advanced systems for collecting and recycling plastics. However, most Californians wash their clothing in washing machines, the water from which empties into more than 200 wastewater treatment plants offshore California. The authors theorize that fibers remaining in sewage effluent from washing machines were ingested by fish sampled in the state.

“To mitigate the issue in each location, it helps to think about local sources and differences in waste management strategies,” Rochman said.

It Takes Guts

The scientists emphasize that the plastic and fibers are found in the fishes’ guts. That means humans are likely to ingest the debris only if the fish is eaten whole, as it is in Indonesia or such as with sardines and anchovies, rather than filleted. However, researchers are still studying whether chemicals in plastic can transfer into the meat.

The study was funded by a UC Davis Outreach and International Program SEED Grant, the National Science Foundation’s Graduate K-12 and IGERT programs and the National Institute of Environmental Health Sciences’ Superfund Research Program.

Temperatures Possible This Century Could Melt Parts of East Antarctic Ice Sheet, Raise Sea Levels 10+ Feet

A section of the East Antarctic Ice Sheet that contains three to four meters (approximately 10 to 13 feet) of potential sea level rise could melt if temperatures rise to just two degrees above pre-industrial levels, a study published in Nature Wednesday found.

Researchers at Imperial College London, the University of Queensland, and other institutions in New Zealand, Japan and Spain looked at marine sediments to assess the behavior of the Wilkes Subglacial Basin during warmer periods of the Pleistocene and found evidence of melting when temperatures in Antarctica were at least two degrees Celsius above pre-industrial levels for periods of 2,500 years or more.

A pipeline released 63,840 gallons (1,520 barrels) of produced water that contaminated rangeland in Dunn County, North Dakota, the Bismarck Tribune reported, citing officials with the North Dakota Department of Health.

Produced water is a byproduct of oil and gas extraction, and can contain drilling chemicals if fracking was used.

World Peace Requires Access to Safe Water

In drought-ravaged East Africa, the cracks in the plains echo the fault lines splitting tribes.

Across the globe, the devastation of deadly brawls is being exacerbated by tensions over access to water. Water crises, often worsened by governance failures, can portend warning signs for instability and conflict. This year, the World Resources Institute cautioned that water stress is growing globally, "with 33 countries projected to face extremely high stress in 2040." The effects of such water stress span the gamut from civil unrest to open warfare.
