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.
Information Extraction from Unstructured Data on Microplastics through Text Mining
Researchers used text mining and natural language processing to analyze unstructured news and social media data about microplastic pollution. The approach revealed hidden trends and public concerns that are not always captured in academic literature, offering a new way to track how awareness of microplastics is evolving.
Ten Years On: A Review of the First Global Conservation Horizon Scan
Researchers revisited 15 conservation topics identified in a landmark 2009 global horizon scan, finding that microplastic pollution was among the five issues that emerged most prominently in scientific literature and public discourse over the following decade, validating early-warning scanning as a conservation planning tool.
Identifying Emerging Issues in the Seafood Industry Based on a Text Mining Approach
Researchers used text mining and keyword analysis of news application programming interfaces to identify emerging issues in the seafood industry, moving beyond traditional literature-based or expert-judgment approaches. The method revealed patterns in topics such as microplastics, food safety, and sustainability that are gaining attention in industry news coverage.
Global research hotspots and trends on microplastics: a bibliometric analysis
A bibliometric analysis of microplastics publications from 1990 to 2022 found a 19-fold increase in publications and 35-fold increase in citations since 2015, with research clustering around distribution, toxicity, analytical methods, and adsorption of co-pollutants.
Divergent shifts in public ecological attention following the COVID-19 pandemic
Researchers analyzed over a decade of social media data from South Korea to understand how the COVID-19 pandemic reshaped public attention to environmental issues including microplastics. The study found that the pandemic acted as a catalyst that restructured how people connect environmental topics, with public discourse around microplastics notably shifting toward more positive sentiment while climate crisis discussions became more negative.
Analysis of Changes in Keywords related to Seoul Tap Water using Text Mining
Researchers analyzed changes in public discourse around Seoul tap water from 1990 to 2024 by applying text mining techniques to 9,861 newspaper articles, using frequency and sentiment analysis to track keyword evolution over time. The study found that dominant concerns shifted from pricing and infrastructure in the 1990s toward water quality issues — including microplastics and contaminants — in more recent decades, reflecting evolving public risk perceptions.
