ClearUtilizing 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.
Harnessing environmental DNA: revolutionizing holistic monitoring of aquatic biodiversity for fishery management under the One Health framework
This review paper examines a new monitoring technique called environmental DNA (eDNA) that can detect fish and other water creatures by testing water samples for genetic material they leave behind. Scientists believe this tool could help better manage fish populations and protect both ocean health and human food security, since healthy fisheries provide food for billions of people worldwide. However, the technology still needs improvements before it can be widely used to make decisions about fishing limits and water safety.
Enhanced eDNA Recovery from Microplastic-Polluted Freshwater Systems Using Surfactant-Assisted Bead-Beating with Enzymatic Digestion
Researchers developed an improved eDNA recovery method combining surfactant-assisted bead-beating with enzymatic digestion to overcome the interference caused by microplastic pollution in freshwater biodiversity monitoring. The approach significantly enhanced eDNA retrieval from contaminated water bodies where conventional methods underperform.
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.

This review describes how environmental DNA (eDNA) tools are expanding capabilities for marine ecosystem monitoring and fisheries research, enabling non-invasive detection of species presence, biodiversity assessment, and tracking of human impacts across large ocean areas.
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.
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.
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.
Microplastics: A Review of Methodology for Sampling and Characterizing Environmental and Biological Samples
This review examines the range of methodologies available for sampling and characterising environmental microplastics, highlighting how variability in collection, separation, detection, and identification procedures limits cross-study comparisons and discussing how complementary technique combinations can improve standardisation and data quality.
A review of methods for measuring microplastics in aquatic environments
This review critically evaluates methods used to measure microplastics in aquatic environments, covering sampling design, sample processing, and spectroscopic identification, and identifies the most significant sources of methodological variation. Standardizing these methods is essential for generating comparable data across studies and enabling robust environmental risk assessment.
In-situ detection of microplastics in the aquatic environment: A systematic literature review
This systematic review evaluates emerging technologies for detecting microplastics directly in water environments without needing to collect samples and bring them to a lab. Developing reliable in-situ detection methods is important because current lab-based approaches are slow and expensive, making it difficult to track where microplastics are concentrated in the water systems that supply drinking water and seafood.
