Displaying items by tag: Microplastics

Small freshwater animals are breaking down microplastics into nanoplastic fragments which can enter the food chain, according to new research by University College Cork (UCC).

In less than four days, the freshwater amphipod, Gammarus duebeni, is able to fragment microplastics into different shapes and sizes, including nanoplastics, the research has found.

These invertebrate animals inhabit Irish streams and are part of a larger group found around the world in freshwater and ocean environments.

Microplastics are plastic pieces smaller than 5 mm, and nanoplastics created by the crustaceans within hours are at least five thousand times smaller in size.

Breakdown of plastics had been thought to occur mainly through very slow processes in the marine environment such as sunlight or wave action.

The findings have “ substantial consequences for the understanding of the environmental fate of microplastics”, study leader Dr Alicia Mateos-Cárdenas, of UCC’s School of BEES and Environmental Research Institute says:

The study also has consequences in terms of the impacts of plastics, she said.

While microplastics can become stuck in the gut of seabirds and fish, current understanding suggests that the smaller nanoplastic particles could penetrate cells and tissues where their effects could be much harder to predict, she noted.

“These invertebrates are very important in ecosystems because they are prey for fish and birds, hence any nanoplastic fragments that they produce may be entering food chains” Dr Mateos-Cárdenas added, urging further “urgently needed” research.

The study was funded by the Environmental Protection Agency, and published in the journal Scientific Reports this week, here

Coastal Notes Coastal Notes covers a broad spectrum of stories, events and developments in which some can be quirky and local in nature, while other stories are of national importance and are on-going, but whatever they are about, they need to be told.

Stories can be diverse and they can be influential, albeit some are more subtle than others in nature, while other events can be immediately felt. No more so felt, is firstly to those living along the coastal rim and rural isolated communities. Here the impact poses is increased to those directly linked with the sea, where daily lives are made from earning an income ashore and within coastal waters.

The topics in Coastal Notes can also be about the rare finding of sea-life creatures, a historic shipwreck lost to the passage of time and which has yet many a secret to tell. A trawler's net caught hauling more than fish but cannon balls dating to the Napoleonic era.

Also focusing the attention of Coastal Notes, are the maritime museums which are of national importance to maintaining access and knowledge of historical exhibits for future generations.

Equally to keep an eye on the present day, with activities of existing and planned projects in the pipeline from the wind and wave renewables sector and those of the energy exploration industry.

In addition Coastal Notes has many more angles to cover, be it the weekend boat leisure user taking a sedate cruise off a long straight beach on the coast beach and making a friend with a feathered companion along the way.

In complete contrast is to those who harvest the sea, using small boats based in harbours where infrastructure and safety poses an issue, before they set off to ply their trade at the foot of our highest sea cliffs along the rugged wild western seaboard.

It's all there, as Coastal Notes tells the stories that are arguably as varied to the environment from which they came from and indeed which shape people's interaction with the surrounding environment that is the natural world and our relationship with the sea.
