Microplastic

Scientists have begun to uncover evidence of how the digestive systems of certain animals can play a part in plastic fragmentation, with the latest concerning a small crustacean that can turn microplastics into “nanoplastics” in just four days.

For some time now, there have been concerns that microplastic particles eaten by fish could be passed along to human seafood consumers. According to a new study, though, such may not be the case with sea bass, and possibly not with many other fish.

While we may think of car exhaust as being a major source of air pollution, automobile tires also hugely contribute to microplastics pollution. A new vehicle-mounted device could help, by gathering the rubber particles that those tires shed.

A new study has revealed the dangers plastic pollution poses to blue mussels, with researchers finding they may ingest three times as much plastic when clumped together in the reef structures commonly seen in nature.

Researchers working to trace the path of plastic waste through the marine environment have discovered the highest concentration of microplastics ever recorded on the seafloor, the result of deep-sea currents that act like conveyor belts for our trash.

A new study out of the UK has revealed what plastic pollution might mean for hermit crabs, with an environment rich in microplastics seeming to affect their cognitive performance when selecting a home.

While no one likes seeing plastic waste floating in our waterways, tiny "microplastic" particles are also a threat to the aquatic environment – and to human health. A study now suggests that nanocellulose could be used to remove them from the water.

Scientists studying the movement of seafloor sediment have found that underwater avalanches are driving microplastics into the deep ocean, which may help researchers better map the distribution of waste throughout the marine environment.

Microplastic pollution is a growing problem, as tiny fragments of plastic enter the environment from sources like tires and synthetic fabrics. A new study now suggests that even activities such as opening plastic bags may be a contributing factor.

The microfibers shed by loads of laundry are a big problem, as they can be ingested by aquatic life upon entering waterways. New research indicates that short, cool washing cycles minimize the generation of those fibers – and keep clothes colorful.

The world's oceans are under threat not only from plastic trash, but also from "microplastics" – many of which take the form of fibers shed by synthetic fabrics as they're being washed. A new system uses sound to capture those fibers at their source.

​​One disconcerting consequence of our huge plastic pollution problem is that we really have no idea where the stuff can end up. The latest locale to surprise scientists looking into such matters is the Arctic, who say that snowfall there is bringing tiny fragments of plastic along for the ride.​
