Impact of Microplastics on Soil's Biodiversity and Public Health
Summary
This book chapter reviews the impacts of microplastic pollution on soil biodiversity and public health, examining how plastic particles disrupt soil microbial communities, affect soil-dwelling invertebrates, and enter the human food chain through contaminated crops.
Microplastic pollution has gained recognition as a pervasive environmental issue, with recent attention extending to its impact on soil ecosystems and potential implications for public health. This chapter reviews current research findings on the impact of microplastics on soil biodiversity and explores the pathways through which these minute particles may pose risks to human health. The study evaluates the mechanisms by which microplastics influence soil-dwelling organisms, including microorganisms, invertebrates, and plants. It investigates the potential for microplastics to alter soil physicochemical properties, disrupt nutrient cycling, and affect the overall biodiversity of terrestrial ecosystems. Special attention is given to the transfer of microplastics within the soil food web and their accumulation in edible crops, highlighting potential exposure routes for humans. In examining the nexus between soil health and public well-being, the abstract also addresses the challenges associated with assessing and quantifying microplastics in soil matrices. The urgent need for standardized methodologies and comprehensive risk assessments is underscored, aiming to bridge current knowledge gaps and inform evidence-based policies for mitigating the impact of microplastics on soil ecosystems and human health.

Impact of Microplastics on Soil's Biodiversity and Public Health
This book chapter examines how microplastic contamination of soil affects biodiversity—including soil microbes, invertebrates, and plants—and discusses the broader public health implications of agricultural soil pollution and potential pathways of human exposure through food.
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.
Effects of microplastics on soil physical, chemical and biological properties
This review examines how microplastics affect soil health, covering their impact on the physical structure, chemical composition, and biological communities of soil ecosystems. Microplastics can alter soil water retention, change nutrient cycling, and harm soil organisms from earthworms to microbes. Since agricultural soils are a major reservoir of microplastics, these changes could affect crop growth and food quality, creating an indirect pathway for microplastic-related harm to human health.
How microplastics are destroying soil and human health
This review examined how microplastics harm soil health — disrupting soil structure, water retention, microbial communities, and nutrient cycling — and how soil degradation translates into risks for human health through food and water contamination. It argues that soil microplastic pollution deserves equivalent attention to aquatic contamination.
Soils in distress: The impacts and ecological risks of (micro)plastic pollution in the terrestrial environment
This review examines how microplastics affect soil ecosystems, including their transport into soils, changes they undergo in the environment, and their interactions with soil organisms. The effects depend heavily on the type, shape, size, and amount of plastic particles present. Understanding these impacts is important because soil contamination with microplastics can affect food production and ultimately human exposure through the food chain.
