ClearEarthworm-microbiome interactions: Unlocking next-generation bioindicators and bioengineered solutions for soil and environmental health
This review explores how earthworms and their associated microbiomes can serve as bioindicators of soil contamination from pollutants including microplastics. Changes in earthworm gut microbial communities can act as early warning signals of soil pollution, and engineered earthworm-microbiome systems show potential for environmental remediation. The study suggests that understanding these biological interactions could lead to new biomonitoring tools for assessing microplastic contamination in terrestrial ecosystems.
Bioindicators of the impacts by microplastics in soil: A Systematic Review : a systematic review
This systematic review identifies organisms that can serve as bioindicators — living warning signs — for microplastic contamination in soil. Certain earthworms, springtails, and other soil creatures show measurable changes when exposed to microplastics, making them useful tools for monitoring pollution levels. Using these natural indicators could help farmers and environmental managers detect microplastic problems before they worsen.
Soil and Sediment Organisms as Bioindicators of Pollution
This review examines how soil organisms like earthworms, insects, and microbes can serve as living indicators of pollution, including contamination from microplastics and heavy metals. Changes in these organisms' behavior, reproduction, or survival can reveal pollution levels that chemical tests alone might miss. The approach is relevant to microplastic research because it provides practical tools for assessing how microplastic contamination in soil affects the ecosystems that support agriculture and food production.
Soil Biochemical Indicators to Monitor the Impact of Microplastics on Soil Functionality in Terrestrial Ecosystems
This paper reviews how soil biochemical indicators — including enzyme activities and microbial community metrics — can be used to assess the impact of microplastics on soil functioning. Because standard chemical analyses alone may miss functional changes, biochemical indicators provide a more sensitive early warning system for detecting microplastic-driven soil health degradation.

This review examines how microplastics accumulate in agricultural soils and the role earthworms may play in breaking them down. Researchers found that microplastics can harm soil health by disrupting microbial communities, enzyme activity, and nutrient availability, but that earthworms can enhance microplastic degradation through their digestive processes and the microorganisms in their gut. The study suggests that earthworm-based bioremediation could be a practical strategy for reducing microplastic contamination in farmland.
Exploring the Impact of Micro-plastics on Soil Health and Ecosystem Dynamics: A Comprehensive Review
This review examines how microplastics affect soil health, finding that they alter soil structure, water retention, and the organisms that live in soil. Microplastics can carry toxic substances into soil and interact with other pollutants to amplify harmful effects on earthworms and soil microbes. Since healthy soil is essential for growing safe food, microplastic contamination of agricultural land could have long-term consequences for the food supply and human health.
The impact of microplastics on soil ecosystems: A review
This review examines how microplastics accumulate in soil from sources like sewage sludge, agricultural plastic mulch, and wastewater, and how they affect soil ecosystems.
