Beneath the Surface: Unmasking the Global Crisis of Soil Pollution
Summary
This review examines soil pollution as a global crisis driven by industrial emissions, intensive agriculture, and poor waste management, covering how heavy metals, pesticides, microplastics, and emerging contaminants accumulate in soils, degrade microbial communities, reduce crop yields, and enter the food chain.
Soil pollution is an escalating global crisis with profound implications for environmental health, agricultural productivity, and food security. Driven by industrial emissions, intensive agriculture, urbanization, and poor waste management, pollutants such as heavy metals, pesticides, microplastics, and emerging contaminants persist in the soil, disrupt its biological functions, and enter the food chain. These toxicants degrade soil microbial communities, reduce crop yields, and impair biodiversity and ecosystem resilience. The impacts extend beyond the farm, contributing to climate change and posing chronic risks to human health through bioaccumulation and biomagnification. Despite its critical importance, soil pollution remains under-monitored, and remediation is often constrained by technical, financial, and institutional challenges. This review synthesizes the sources, classifications, pathways, and ecological impacts of soil contaminants, while critically examining current remediation strategies and policy frameworks. It underscores the urgent need for integrated soil health management, robust legal regulations, enhanced public awareness, and innovative sustainable practices to restore and protect this vital resource.

Asia’s soil contamination crisis: causes, consequences, and sustainable solutions: a comprehensive review
This review addresses Asia's soil contamination crisis, examining how rapid urbanization, intensive agriculture, and poor waste management have created widespread heavy metal and microplastic soil pollution threatening food security, biodiversity, and human health across the continent.
Soil Contamination, Risk Assessment, and Remediation
This review covers soil contamination from various sources including agrochemicals, waste materials, and emerging pollutants like microplastics, along with methods for risk assessment and remediation. Researchers examined how human activities such as farming, waste disposal, and industrial practices contribute to soil pollution and disrupt soil fertility. The study emphasizes the need for comprehensive risk assessment frameworks that account for the complex interactions between traditional and emerging soil contaminants.
Paving the way toward soil safety and health: current status, challenges, and potential solutions
This review examines the global threats to soil health from industrial chemical contamination and explores potential solutions including monitoring, advanced remediation technologies, and holistic soil management. While covering soil pollution broadly, it is relevant to microplastics because they are a major and growing soil contaminant that is extremely difficult to remove once introduced. The review emphasizes that preventing pollutants from entering soil is far more effective and less costly than trying to clean up contamination afterward.
Agricultural Environmental Pollution, Risk Assessment, and Control
This book chapter reviews the growing burden of agricultural environmental pollution — from pesticide residues to microplastics and heavy metals — and evaluates risk assessment frameworks and control strategies for protecting soil health and food safety.
Soil under stress: The importance of soil life and how it is influenced by (micro)plastic pollution
This review examines how plastic pollution in soil disrupts soil organisms and microorganisms that regulate essential ecosystem functions, finding that plastic alters soil chemistry, physical structure, and microbial communities in ways that threaten primary production and carbon cycling.
