ClearMicroplastics 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.
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 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.

The authors evaluate current remediation technologies and highlight the need for better landfill management to reduce this growing source of microplastic pollution.
Microplastics in landfill leachate: Occurrence, health concerns, and removal strategies
This review examines how microplastics form and accumulate in landfill leachate, the liquid that drains from waste sites.

Microplastics in landfill and leachate: Occurrence, environmental behavior and removal strategies
This review examines how microplastics form and accumulate in landfills and their leachate, which is the liquid that drains from waste sites. 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.

This review synthesizes findings on microplastics in landfill leachate, identifying it as an underappreciated environmental source of microplastic contamination generated by physical, chemical, and biological breakdown of plastic waste. The authors outline characteristics, detection methods, and pathways by which leachate-borne microplastics enter the broader environment.
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.
Sources, 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.
Sources, Occurrence, and Removal of Microplastic/Nanoplastic in landfill leachate: A Comprehensive Review
This review examined microplastic and nanoplastic contamination in landfill leachate, finding raw leachate concentrations of 0-382 items/L globally, with polyethylene, polystyrene, and polypropylene as the dominant polymers. The authors assessed detection methods, occurrence patterns, and remediation strategies, noting that treatment can reduce concentrations to 0-2.7 items/L.
Microplastics in landfill leachate and its treatment

Exploring the abundance of microplastics in Indian landfill leachate: An analytical study
Researchers analyzed microplastics in leachate from two major landfills in India and found concentrations of 1,473 to 2,067 particles per liter, with most particles smaller than 100 micrometers. Polyethylene terephthalate, polypropylene, cellulose acetate, and PVC were the most common plastic types identified. Since landfill leachate can seep into groundwater and nearby water bodies, these findings raise concerns about microplastic contamination of drinking water sources near dump sites.

Global perspective on microplastics in landfill leachate; Occurrence, abundance, characteristics, and environmental impact
This review provides the first global overview of microplastic contamination in landfill leachate, the liquid that seeps out of garbage dumps. Microplastic levels varied widely, with the highest concentrations found in Shanghai at 291 particles per liter, and polyethylene was the most common type worldwide. Since landfill leachate can seep into groundwater and nearby waterways, this represents an important but often overlooked source of microplastic pollution that could affect drinking water supplies.
Pervasiveness and classification of microplastics in Landfill Leachate: Impacts, risks, and treatment efficiency
Researchers assessed microplastic contamination from the Matuail landfill in Bangladesh, finding that leachate discharged approximately 350 million particles per hour into surrounding water. Surface water and groundwater near the landfill contained even higher microplastic concentrations than the leachate itself, with fibers and fragments of polyethylene and polypropylene dominating. The study found that the existing leachate treatment facility was inefficient at removing microplastics, posing high ecological risk to surrounding water sources.
