ClearA bibliometric perspective on the occurrence and migration of microplastics in soils amended with sewage sludge
Researchers used bibliometric analysis to map the growing body of research on microplastics in soils that receive sewage sludge. The study suggests that applying sewage sludge to farmland introduces thousands to hundreds of thousands of microplastic particles per kilogram into the soil, with estimated annual accumulations reaching into the trillions of particles across China and Europe.

Assessing emerging and priority micropollutants in sewage sludge: environmental insights and analytical approaches
Researchers reviewed the presence of emerging pollutants, including microplastics, pharmaceuticals, and industrial chemicals, in sewage sludge that is commonly applied to agricultural land. They found that current analytical methods are improving but still face challenges in detecting these contaminants at low concentrations in complex sludge samples. The study highlights the environmental risks of spreading pollutant-laden sludge on farmland and calls for better monitoring standards.
Emerging trends in tackling microplastics in wastewater systems: Insights from a global research perspective
This bibliometric analysis mapped global research on microplastics in wastewater systems by reviewing over 2,200 studies published between 2009 and 2024. Research output has grown dramatically, peaking at 539 studies in 2024, with China leading contributions and polystyrene, polyethylene, and PET being the most commonly studied plastic types. The review identifies key knowledge gaps and highlights innovative treatment approaches like biochar and adsorption as promising strategies for removing microplastics from wastewater.
Global microplastics pollution: a bibliometric analysis and review on research trends and hotspots in agroecosystems
Researchers conducted a bibliometric analysis of over 1,600 publications on microplastic pollution in agricultural ecosystems from 2012 to 2024, identifying China, the USA, Germany, and India as leading contributors. The analysis revealed emerging research hotspots including biochar remediation, biodegradable microplastics, and antibiotic resistance genes associated with plastic contamination. The study provides a comprehensive overview of how microplastics affect soil properties, microbial communities, and crop productivity, while identifying key knowledge gaps for future research.
Assessing metal contamination and speciation in sewage sludge: implications for soil application and environmental risk
This systematic review estimated that global sewage sludge production could triple to 160 million tons if all wastewater were treated to EU standards, and found that metals in sludge applied to farmland are predominantly in less bioavailable forms. The research is relevant to microplastics because sewage sludge is a major pathway for microplastic contamination of agricultural soils, carrying both metal and plastic pollutants to farmland.
Trends, challenges, and research pathways in emerging contaminants: a comprehensive bibliometric analysis
This large-scale bibliometric analysis reviewed over 62,000 studies on emerging contaminants published between 2000 and 2024, finding that microplastics are among the fastest-growing areas of environmental health research. The analysis highlights that understanding how microplastics interact with other pollutants like pharmaceuticals and endocrine disruptors is a critical frontier for protecting human health.
Bibliometric Analysis on the Papers Dedicated to Microplastics in Wastewater Treatments
A bibliometric analysis of microplastics research in wastewater treatment found rapid growth in publications since 2015 with China and the EU dominating output, identifying removal efficiency, microplastic characterization, and sludge as the most-studied subtopics and highlighting ecotoxicology and health impacts as underdeveloped areas needing more attention.
Bibliometric analysis of global performance and trends of research on combined sewer overflows (CSOs) from 1990 to 2022
This bibliometric analysis mapped global research trends on combined sewer overflows from 1990 to 2022, identifying key themes and emerging topics. The study highlights how sewer overflows serve as major pathways for pollutants including microplastics to enter urban water systems, with research increasingly focusing on their environmental and public health impacts.
A bibliometric analysis of emerging contaminants (ECs) (2001−2021): Evolution of hotspots and research trends
This bibliometric analysis reviewed approximately 8,000 research publications on emerging contaminants from 2001 to 2021 to track how the field has evolved. Researchers found that the focus has shifted over time from simply identifying contaminants to understanding their sources, risks, and control strategies. The study highlights that microplastics, antibiotic resistance genes, and pharmaceuticals are among the fastest-growing areas of emerging contaminant research.
