Utilizing aquatic environmental DNA to address global biodiversity targets
This review explores how environmental DNA (eDNA) analysis from water samples can help monitor aquatic biodiversity and track ecosystem health. While not directly about microplastics, eDNA technology is increasingly being adapted to study how plastic pollution affects aquatic ecosystems and species diversity. Better biodiversity monitoring tools help scientists understand the broader ecological impacts of microplastic contamination on the water systems that support human food and resources.
A State-of-the-Art Review of Aquatic eDNA Sampling Technologies and Instrumentation: Advancements, Challenges, and Future Prospects
This review surveys the current state of environmental DNA sampling technologies used to monitor aquatic biodiversity, covering methods from simple water filtration to automated in-situ samplers. Researchers found that while eDNA methods offer significant advantages over traditional species surveys, challenges remain in standardizing collection protocols and preventing contamination. The technology has broad implications for monitoring ecosystem health, including tracking how environmental stressors like pollution affect aquatic communities.
Exploitation of environmental DNA (eDNA) for ecotoxicological research: A critical review on eDNA metabarcoding in assessing marine pollution
This review examines how environmental DNA (eDNA) analysis -- a method that detects organisms through DNA traces left in water -- can be used to monitor the effects of marine pollution, including plastic waste. While eDNA does not detect plastics directly, it reveals how pollution changes the biodiversity of marine communities, serving as an early warning system. The approach could help scientists better track the ecological damage caused by microplastic contamination in oceans.
Environmental DNA in an Ocean of Change: Status, Challenges and Prospects
This review examines the status, challenges, and prospects of environmental DNA (eDNA) research in marine systems, surveying literature on metazoan eDNA studies to assess progress in detecting species distributions, biodiversity, and biomass, and highlighting future opportunities including marine time series, population genetics, natural sampler DNA, and eDNA-based trophic network reconstruction.
Effectiveness assessment of using water environmental microHI to predict the health status of wild fish
Researchers tested whether measuring the health of microbial communities in river water could predict the health status of wild fish living there. The study found that the environmental microbiota health index was effective for bottom-dwelling fish but less reliable for fish living in the open water, suggesting this non-invasive monitoring approach works best for certain types of aquatic species.
Emerging technologies revolutionising disease diagnosis and monitoring in aquatic animal health
This review covers new technologies for diagnosing diseases in farmed fish, including biosensors, genetic sequencing, and AI-powered monitoring systems. While not directly about microplastics, the advances are relevant because microplastic contamination in aquaculture environments can stress fish and increase disease susceptibility. Better disease detection in farmed fish helps protect the safety of seafood that humans consume.
Population genetic assessment of marine megafauna using seawater environmental DNA: a case study of whale sharks from the Ningaloo Coast World Heritage Area.
Researchers developed a population genetics method using seawater environmental DNA to genetically assess whale sharks at the Ningaloo Coast World Heritage Area, demonstrating a scalable and non-invasive alternative to tissue biopsy for monitoring endangered and elusive marine megafauna.
Application of Environmental DNA in the Air for Monitoring Biodiversity
This review examines the use of airborne environmental DNA as a non-invasive tool for monitoring biodiversity across multiple species groups simultaneously. While focused on biodiversity monitoring methodology, the study contributes to understanding how atmospheric sampling techniques can be used to track biological and environmental changes, including the presence of airborne contaminants.
Current Status of Omics in Biological Quality Elements for Freshwater Biomonitoring
This review examines how advanced molecular techniques like DNA barcoding, environmental DNA analysis, and metagenomics are being applied to freshwater biomonitoring alongside traditional biological assessment methods. Researchers found that these omics-based approaches can provide faster, more comprehensive biodiversity assessments than conventional methods, but significant challenges remain in standardizing protocols and interpreting results. The study highlights how these tools could improve the detection of ecosystem impacts from emerging threats including microplastic pollution.

Researchers applied environmental DNA (eDNA) metabarcoding to characterise vertebrate biodiversity in three Sicilian freshwater lakes, providing the first systematic snapshot of fish and other vertebrate communities in these understudied ecosystems. The study demonstrated that eDNA surveys can detect species assemblages efficiently and non-invasively in lakes subject to anthropogenic pressures.

Microplastics as persistent and vectors of other threats in the marine environment: Toxicological impacts, management and strategical roadmap to end plastic pollution
Researchers analyzed how microplastics spread through marine environments, acting as rafts for toxic chemicals and dangerous biofilms that infiltrate the food chain — a problem worsened by COVID-19's surge in single-use plastic waste. The review highlights emerging environmental DNA tools as a way to better track and manage marine microplastic contamination.
Are We Underestimating Microplastic Contamination in Aquatic Environments?
This review argues that current microplastic monitoring methods likely underestimate the true extent of contamination in aquatic environments, especially for small particles and fibers. The authors call for standardized, more sensitive detection methods to better inform regulation and risk assessment.
Adsorption and Protection of Environmental DNA (eDNA) on Polymer and Silica Surfaces
Environmental DNA (eDNA) was found to adsorb onto and be protected by plastic particles in water, meaning microplastics can preserve genetic material shed by aquatic organisms. This has dual implications: microplastics may interfere with eDNA-based biodiversity monitoring while also potentially serving as DNA carriers in ecosystems.

This review evaluates viral metagenomics as a tool for tracking sources of fecal contamination across water, food, soil, and air within a One Health framework. Researchers found that viral metagenomics can complement traditional culture and PCR-based methods by identifying a broader range of viral indicators with narrow host ranges. The study discusses both the promise and current limitations of this approach, including challenges in sample processing and bioinformatics analysis.
Microplastics in aquatic environments: A comprehensive review of toxicity, removal, and remediation strategies
This comprehensive review covers the toxicity of microplastics on aquatic life at every level of the food chain, from algae to fish, as well as current methods for removing microplastics from water. Treatment methods like filtration and electrocoagulation can remove over 86-90% of microplastics, but no single method eliminates them completely. The review highlights the urgent need for better water treatment to protect both aquatic ecosystems and the humans who rely on them for food and water.
