Shocking Discovery: Microplastic Pollution Uncovered in Appalachian Streams by West Virginia University Study

A recent study by West Virginia University found microplastics in every fish tested across seven freshwater streams in North Central Appalachia. Isabella Tuzzio, an undergraduate biology student, discovered these tiny plastic pieces—each smaller than 5 millimeters—in juvenile northern hogsucker fish swimming in the Cheat, Ohio, and Monongahela Rivers.

Tuzzio’s research fills an important gap in our understanding of freshwater ecosystems, an area often overshadowed by studies focused on oceans. She chose northern hogsuckers because they feed near the stream bottom, where microplastics tend to settle. On average, each fish contained around 40 pieces of plastic, accumulating to a total of 2,185 microplastics across the study.

To understand the larger picture, Tuzzio and her team also looked at land use and collected samples for E. coli, a bacteria linked to sewage. They noted the highest concentration of plastics in the Cheat watershed, correlating with agricultural activities and the presence of E. coli. “Our local human activities contribute significantly to microplastic pollution,” she stated.

Microplastics can originate from various sources. Most commonly, they break off from larger plastic items, come from microbeads in cosmetics, or shed from clothing during wash cycles. Interestingly, Tuzzio noted that around 98% of the plastics found were fibers from textiles, highlighting the impact of our laundry habits on water pollution.

A 2021 study pointed out a significant lack of research on microplastics in freshwater bodies compared to marine environments. This absence is especially pronounced in Appalachia, making Tuzzio’s work crucial for establishing baseline data on local water quality.

Brent Murry, an aquatic ecology professor involved in the study, echoed this sentiment. He drew parallels between Tuzzio’s findings and previous research on adult fish in larger rivers, noting that microplastic levels appear similar regardless of ecosystem size. “We have many unanswered questions. Microplastics are an emerging issue, and we are just beginning to grasp their effects,” he said.

The ecological consequences are worrying. Caroline Arantes, another researcher on the team, explained that microplastics can disrupt food chains. Their surfaces often carry harmful pollutants and pathogens. As smaller fish ingest these plastics, toxins can accumulate, affecting larger predators—including humans. This raises alarms about the potential health risks associated with consuming contaminated fish, such as elevated rates of cancer and various diseases.

Research shows that approximately 1.5 million tons of microplastics enter freshwater ecosystems annually, creating serious environmental threats. The escalating issue of microplastic pollution is compounded by other stressors like climate change, urbanization, and overfishing, which together place freshwater ecosystems at significant risk.

In light of these findings, Tuzzio encourages individuals to reduce plastic use and recycle. Simple actions, like picking up litter near water sources, can help mitigate some pollution.

Moving forward, collaborative efforts are essential. Murry noted the importance of interdisciplinary teamwork, mentioning a partnership with the fashion design department. They are exploring ways to create fabrics that shed fewer fibers, aiming to reduce pollution at the source.

Tuzzio’s research is just the beginning. Following her study, a new initiative, One Health West Virginia, will begin exploring additional freshwater springs across the state. Other students will expand on her work, investigating various species to deepen our understanding.

This foundational study not only highlights the pressing issue of microplastics but also sparks ongoing conversations about freshwater conservation. It underscores the immediate need to address human actions that impact our waterways, not just for aquatic life but for our health too.
