Topic modeling discovers trending topics in global research on the ecosystem impacts of microplastics

Researchers applied computational topic modeling to analyze how global microplastic research on ecosystem impacts has evolved across topics, regions, and time periods. The analysis identified trending research themes including terrestrial microplastics and biological interactions while revealing that marine-focused topics remain dominant, helping map the next frontiers for microplastic ecology research.

Topic modeling discovers trending topics in global research on the ecosystem impacts of microplastics

A topic-modeling analysis of global microplastic research literature identified nine dominant research themes and tracked how the field has shifted over time — from aquatic to terrestrial environments, from distribution mapping to fate/transport, and from gross physiological toxicity to cellular and genetic damage. The analysis also found that research is heavily concentrated in a handful of wealthy nations, leaving major gaps in understanding microplastic impacts in the most heavily polluted but under-studied regions of the world.

An issue analysis on microplastics using topic modeling

This Korean study used topic modeling (LDA algorithm) to analyze news coverage of microplastics from 2001 to 2022, extracting ten major topic clusters. The analysis found that public discourse has centered on health and safety, environmental pollution, single-use waste, policy, and citizen action — insights that can help align research priorities with public concerns.
