Microplastic

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.​

​In recent years, we've seen a number of research groups develop waterproof adhesives inspired by the fibers that mussels use to cling to rocks. Unfortunately, though, the mussels themselves may be losing their grip on those rocks, due to marine microplastic pollution.

​​There remains a lot we don't know about the whereabouts of the all the plastic waste that washes into the ocean each year, but scientists are continuing to discover bits and pieces in increasingly concerning places, a list that now includes turtles.

The insidious​ spread of microplastics through our environment is something that we really don't know enough about. Researchers have now found unexpected quantities of the material lodged in Arctic sea ice, shedding new light on how they move through the ocean.
