Sentinel species selection for monitoring microplastic pollution: A review on one health approach

This review evaluates how sentinel species, organisms used as biological indicators, can be selected to monitor microplastic pollution across different environments using a One Health approach that connects ecosystem, animal, and human health. Researchers assessed various candidate species including mussels, fish, and birds based on their ability to accumulate and reflect microplastic contamination. The study provides a framework for choosing the most informative species to track plastic pollution's impact across interconnected ecosystems.

Bioindicators selection in the strategies for monitoring microplastic pollution

Researchers reviewed strategies for selecting the best 'sentinel' species — from mussels to earthworms — to serve as biological indicators of microplastic and nanoplastic pollution in both aquatic and land environments. Choosing the right species based on behavior, habitat, and exposure pathways is essential for building consistent, comparable monitoring programs that can track plastic pollution over time.

Microplastic toxicity: A review of the role of marine sentinel species in assessing the environmental and public health impacts

Researchers reviewed how marine animals — particularly seabirds like the herring gull — can serve as sentinel species to monitor the real-world health effects of microplastic exposure across ecosystems. Because plastic pollution affects biological pathways shared across many species including humans, studying wildlife that naturally ingests varying amounts of plastic offers valuable insights into long-term toxicity risks.

One is not enough: Monitoring microplastic ingestion by fish needs a multispecies approach

Researchers found that monitoring microplastic ingestion by fish requires a multispecies approach, as different feeding guilds — benthic, demersal, and pelagic — accumulate microplastics at varying rates and sizes, making any single-species indicator insufficient for assessing marine contamination.

Mangrove mud clam as an effective sentinel species for monitoring changes in coastal microplastic pollution

Researchers collected mangrove mud clams from 18 stations along China's Leizhou Peninsula to evaluate their effectiveness as sentinel organisms for monitoring coastal microplastic pollution. They found that microplastic contamination in the clams correlated with local pollution levels, making them useful biological indicators. The study suggests that this widely distributed species could serve as a standardized tool for tracking changes in coastal microplastic contamination over time.

Monitoring Microplastics and Nanoplastics in a Marine Realm

This review examines the biomonitoring potential of a wide range of marine organisms — from low-trophic-level species to apex predators — as sentinel species for tracking microplastic and nanoplastic pollution in the ocean under the Marine Strategy Framework Directive. The authors synthesize research on microplastic ingestion, accumulation, uptake, and egestion to guide selection of sentinel species and inform policymakers and environmental managers.

Tracing Microplastic Pollution Through Animals: A Narrative Review of Bioindicator Approaches

This review evaluates animals that have been proposed as bioindicators for monitoring microplastic pollution across aquatic, terrestrial, and aerial environments. Researchers found that bivalves like clams and mussels are among the most suitable indicators due to their wide distribution, effective microplastic retention, and well-established analytical methods. The study provides a framework for selecting appropriate sentinel species based on ecological, physiological, and methodological criteria.

Hit the target: A new experimental method to select bioindicators of microplastic ingestion by marine fish

Researchers developed a scoring system to identify the best fish species for monitoring microplastic pollution in the marine environment. Testing eight fish species from the central Tyrrhenian Sea, they evaluated factors like how readily each species ingests microplastics and how well they reflect local contamination levels. The approach aims to help standardize biomonitoring programs across different marine regions as required by European environmental legislation.
