ClearAquatic ecosystem indices, linking ecosystem health to human health risks
Researchers reviewed indicators used to assess aquatic ecosystem health and found that most existing tools don't adequately capture the risks that degraded water ecosystems pose to human health and well-being. They propose a new set of combined indicators — covering chemical contaminants, pathogens, and biological markers — to better link ecosystem health monitoring to human health outcomes.
Development of Ecosystem Health Assessment (EHA) and Application Method: A Review
This review traces the development of ecosystem health assessment methods, comparing biological indicator approaches and index system methods and analyzing how they have been applied to assess the health of aquatic, terrestrial, and urban ecosystems under anthropogenic stress.
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.
Multiple approach for assessing lagoon environmental status based on water bodies quality indices and microplastics accumulation
Researchers assessed lagoon environmental status using water quality indices and microplastic accumulation measurements, finding that combining these multiple approaches provides a more comprehensive evaluation of lagoon ecosystem health than single metrics alone.
Ecological Security Evaluation of Marine Ranching Based on DEMATEL-Fuzzy Comprehensive Evaluation
This study developed a multi-factor scoring system to evaluate the ecological health and security of marine ranching areas in China. Marine ranching ecosystems are increasingly threatened by microplastic pollution, making ecological security assessments important for sustainable fisheries management.
Towards Adaptive Water Quality Indexing: Integrating Fuzzy Logic for Improved Contaminant Detection and Treatment Planning
This study proposed integrating fuzzy logic into water quality index calculations to better handle the uncertainty and compounding effects of emerging contaminants such as pharmaceuticals, microplastics, and personal care products that conventional water quality indices were not designed to assess.
A preliminary study of direct observation and selected water quality monitoring in Putrajaya Lake: the status between October-December 2022
Researchers conducted a preliminary study combining direct observation of aquatic environments with selected water quality monitoring parameters, developing a simplified field methodology for rapid assessment of freshwater ecosystem health. The approach demonstrated that combining visual habitat assessment with targeted chemical measurements could efficiently characterize ecological condition in resource-limited monitoring contexts.
Application of pressure–state–response approach for developing criteria and indicators of ecological health assessment of wetlands: a multi-temporal study in Ichhamati floodplains, India
Researchers developed and tested a comprehensive 105-indicator framework for assessing the ecological health of tropical floodplain wetlands in eastern India, applying it across seven sites over multiple years. The results showed that agriculture-dominated wetlands were the most degraded, while fishing-dominated wetlands fared better, offering a replicable tool for wetland management in similar regions.
A Comprehensive Method for Water Environment Assessment considering Trends of Water Quality
Researchers developed a comprehensive water quality assessment method that accounts for both current pollution levels and trends over time, applying it to rivers feeding a major Chinese reservoir. Water quality assessment frameworks are increasingly being adapted to include microplastic contamination as a standard monitoring parameter.
The Baltic Health Index (BHI): Assessing the social–ecological status of the Baltic Sea
Researchers introduced the Baltic Health Index (BHI) as a transparent, collaborative tool that integrates ecological and human-dimension metrics to assess the social-ecological health of the Baltic Sea, complementing existing ecological status frameworks.
Monitoring of Rivers and Streams Conditions Using Biological Indices with Emphasis on Algae: A Comprehensive Descriptive Review toward River Management
This comprehensive review examines algal communities as biological indicators of river and stream health, covering how algal indices respond to changes in nutrient levels, salinity, flow regime, and other environmental variables relevant to river management and ecological assessment.
River ecosystem processes: A synthesis of approaches, criteria of use and sensitivity to environmental stressors
This synthesis reviewed approaches to studying river ecosystem processes, evaluating criteria for selecting sensitive indicators and methods for detecting ecological change driven by pollution and land-use pressures.
Biological indicators to check water quality in plastic-heavy water bodies
This review examines the use of biological indicators for monitoring water quality in environments heavily contaminated with plastics and heavy metals, summarizing recent advances in bioindicator approaches for tracking pollution trends and environmental health effects in plastic-polluted water bodies.
Assessing the Ecological Status of European Rivers and Lakes Using Benthic Invertebrate Communities: A Practical Catalogue of Metrics and Methods
A comprehensive catalog of benthic invertebrate metrics used across 26 EU national assessment systems for rivers and 21 for lakes was compiled, identifying the range of biological indices and methodological approaches currently used to evaluate ecological status under the Water Framework Directive.
Assessing land-use impacts on a 5th-order tropical river using multiple environmental indicators
Researchers combined multiple environmental indicators to assess the health of a tropical river system in Brazil affected by land-use change from agriculture and urbanization. Rivers in degraded landscapes also carry higher microplastic loads, and multi-indicator approaches provide a more complete picture of ecosystem health.
Novel Quantitative Evaluation of Biotreatment Suitability of Wastewater
This study developed a new framework for evaluating how suitable wastewater is for biological treatment, going beyond standard water quality indicators. Better assessment tools could improve wastewater treatment efficiency and reduce pollutant discharges, including microplastics.

Biologia Futura: integrating freshwater ecosystem health in water resources management
This paper argues that sustainable water resource management must integrate freshwater ecosystem health as a priority, proposing that freshwater bodies should be treated as 'water users' with their own biological and physicochemical requirements.
Assessment of potential ecological risk for microplastics in freshwater ecosystems
Researchers assessed the ecological risk of microplastics across freshwater ecosystems worldwide, including rivers and lakes in China, Vietnam, Europe, and South America. While one risk method showed negligible danger, more comprehensive assessment approaches revealed extreme ecological threats at every location studied, suggesting that microplastic pollution in freshwater may be more serious than previously thought.
