AI Article Synopsis
- Scientists found tiny particles, called anthropogenic microparticles (AMs), in fish from Antarctica that were collected in 1998.
- Most of these particles were fibers, both natural and made by humans, like polyester and polypropylene, which are used in clothes and other items.
- The study shows that pollution from microplastics had already started affecting the Antarctic ocean environment long before we often think it began, helping us understand how pollution has changed over time.
Article Abstract
Anthropogenic microparticles (AMs) were found for the first time in specimens of Trematomus bernacchii collected in 1998 in the Ross Sea (Antarctica) and stored in the Antarctic Environmental Specimen Bank. Most of the identified AMs were fibers of natural and synthetic origin. The natural AMs were cellulosic, the synthetic ones were polyester, polypropylene, polypropylene/polyester, and cellulose acetate. The presence of dyes in the natural AMs indicates their anthropogenic origin. Five industrial dyes were identified by Raman spectroscopy with Indigo occurring in most of them (55%). Our research not only adds further data to the ongoing knowledge of pollution levels in the Antarctic ecosystem, it provides an interesting snapshot of the past, highlighting that microplastics and anthropogenic fiber pollution had already entered the Antarctic marine food web at the end of the '90 s. These findings therefore establish the foundations for understand the changes in marine litter pollution over time.
