ClearSources, distribution, and impacts of emerging contaminants – a critical review on contamination of landfill leachate
This review examines how landfill leachate, the liquid that drains from garbage dumps, carries emerging contaminants including microplastics into surrounding soil and water. The authors warn that microplastics in landfill leachate are a growing environmental threat and call for better treatment technologies to prevent contamination of groundwater and nearby ecosystems.
Microplastics as emergent contaminants in landfill leachate: Source, potential impact and remediation technologies
This review examines how landfills generate microplastics as buried plastic waste gradually degrades from physical, chemical, and biological processes. These microplastics enter the environment through leachate, the contaminated liquid that seeps from landfills into surrounding soil and groundwater. The authors evaluate current remediation technologies and highlight the need for better landfill management to reduce this growing source of microplastic pollution.

Prevalence of antibiotics and antibiotic resistance genes in landfill leachate
This book chapter reviews how landfills accumulate and release antibiotics and antibiotic resistance genes (ARGs) into surrounding groundwater and surface water through leachate — with microplastics mentioned as one of many co-contaminants in landfill environments. While the focus is primarily on antimicrobial resistance rather than microplastics specifically, the work is relevant to understanding how plastics in landfills interact with the broader contamination landscape. The findings highlight landfills as underappreciated hotspots for combined chemical and biological pollution entering water supplies.

Researchers found that landfill leachate is an overlooked source of microplastic pollution that can carry toxic substances and antibiotic resistance genes into the surrounding environment. The study evaluates current removal strategies and calls for better treatment systems to prevent microplastic contamination from waste disposal sites.
Microplastics in landfill leachate: Sources, abundance, characteristics, remediation approaches and future perspective
This review examines the sources, abundance, and characteristics of microplastics found in landfill leachate, a difficult-to-treat waste liquid that can carry pollutants into the environment. The authors highlight the urgent need for standardized microplastic analysis methods and more research into cost-effective approaches for removing microplastics from leachate before it reaches waterways.
Occurrence of per- and polyfluorinated substances, microplastics, pharmaceuticals and personal care products as emerging contaminants in landfill leachate: A review
This review examines how landfill leachate -- the liquid that seeps out of waste dumps -- contains significant levels of emerging contaminants including PFAS ("forever chemicals"), microplastics, and pharmaceutical residues. These pollutants can leak into groundwater and surface water at concentrations influenced by landfill age and composition, posing ongoing risks to drinking water safety and human health.
Sources, health risks, environmental implications, and management strategies of microplastics with a focus on landfill leachate
This review examines microplastics in landfill leachate as a significant but underappreciated source of environmental contamination, covering detection methods, particle characteristics (type, size, color, shape), and the health and environmental risks of landfill leachate that enters groundwater and surface water.
A review on microplastics in landfill leachate: formation, occurrence, detection, and removal techniques
This review examined microplastics in landfill leachate, covering their formation from degrading plastic waste, reported concentrations in leachate, detection methods, and available removal technologies. The authors identify landfill leachate as a significant and underregulated source of microplastic release into surrounding environments.
Microplastics in landfill leachate - characteristics and common methods of identification
This review characterized microplastics in landfill leachate, covering their physical and chemical properties and the common analytical methods used for identification. Around 40% of global plastic waste ends up in landfills, making leachate a significant but understudied pathway for microplastic release into groundwater and surrounding environments.
Microplastics in landfill leachate: Sources, detection, occurrence, and removal
This review examines how landfills have become a significant source of microplastics entering the environment through leachate -- the liquid that seeps out of waste. Polyethylene, polystyrene, and polypropylene are the most common microplastics found in landfill leachate, and while treatment can remove up to 100% of them, many facilities are not yet equipped to filter these particles before they contaminate surrounding water sources.
Hazardous Components of Landfill Leachates and Its Bioremediation
This review covers the hazardous substances found in landfill leachate—the liquid that drains through garbage dumps—and biological methods to treat them. Landfill leachate is a significant but underappreciated source of microplastic pollution and chemical contamination in groundwater and surrounding ecosystems.
