In order to examine trends in microplastic pollution over time, a new study published in Science of the Total Environment tested museum specimens of lantern fish collected over a 54 year period for microplastics and microfibers.
In short:
- Fish that were collected near the U.S. west coast showed an increase in microplastic and microfiber ingestion over time.
- 50% of the tested specimens collected between 2005 - 2009 contained microplastics and microfibers, compared to just 5% of specimens from 1960 - 1965.
- The majority of the particles found in specimens were blue and black microfibers, which are one of the most common types of microparticle pollution globally.
Key quote:
“Given the ongoing generation and persistence of microplastics in the environment, it is crucial to understand and anticipate the impacts these particles will have on humans and wildlife.”
Why this matters:
Plastic use has continued to grow exponentially since the mid-twentieth century, with nearly a metric ton of plastic waste produced for every person on the planet. Studies have found microplastics and microfibers in everything from food to all parts of the human body that have been examined so far, but our understanding of microplastics’ impact on wildlife is still limited. Further research will be critical for creating policies and regulatory interventions that address the plastic pollution crisis.
