Microplastics in urban rivers create unique habitats for specific bacterial communities
In short: Researchers studying a highly urbanized river in Chicago found that microplastics serve as a distinct habitat for microbes. By analyzing the river's water, the team discovered that the bacterial communities living on these tiny plastic particles were significantly less diverse and taxonomically different from the bacteria found in the surrounding water or organic matter.
The study highlights how urban rivers act as overlooked links in the global microplastic life cycle, with wastewater treatment plants identified as a primary source. The researchers used high-throughput sequencing to compare microbial assemblages, finding that plastics hosted higher proportions of pathogens and plastic-decomposing organisms. However, the study is limited to a single urban river location, which may not represent all river systems globally.
Why it matters: Microplastics aren't just floating debris; they act as specialized transport vessels for unique and potentially harmful bacterial communities.
