A study published in Nature reveals for the first time the extent to which nanoplastic pollutes the North Atlantic.
A study published in Nature reveals for the first time the extent to which nanoplastic pollutes the North Atlantic.
Plastic particles less than one micrometre in size are found across the globe – from the peaks of the Alps to the depths of the oceans. A research team from the Helmholtz Centre for Environmental Research (UFZ), Utrecht University, and the Royal Netherlands Institute for Sea Research (NIOZ) investigated the presence of nanoplastic in the North Atlantic. The findings show that nanosized plastic particles are present at all depths between the temperate and subtropical zone of the ocean. By mass, the amount of nanoplastic is comparable to that of microplastic. An article published in Nature concludes that nanoplastic plays a far greater role in marine plastic pollution than previously assumed.
Plastic waste pollutes oceans across all regions of the world. Marine animals may become entangled in larger plastic debris such as nets and bags or mistake smaller pieces for food. Ingested plastic can block or injure the gastrointestinal tract. The smallest plastic particles in the micro and nano range are mostly excreted, but a small proportion can pass through the intestinal wall and enter the bloodstream.
