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.

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.

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. As plastic waste breaks down in landfills, it releases microplastic particles that can contaminate surrounding soil and water. The authors assess health concerns from leachate-borne microplastics and evaluate removal strategies, highlighting an often-overlooked pathway for microplastic pollution.

Microplastics in landfill leachate and its treatment

This review examines microplastic contamination in landfill leachate, documenting that polyethylene and polypropylene are the most frequently detected polymers in sizes ranging from 20 to 5,000 micrometers, with fibers, foams, films, beads, and fragments all present. The authors detail migration pathways through which leachate microplastics reach surrounding soils, groundwater, and open water bodies, and assess the effectiveness of current leachate treatment technologies for microplastic removal.

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.

Microplastics in municipal solid waste landfill leachate and their removal in treatment units: A perspective of controlled and uncontrolled landfills

This study measured microplastic contamination in liquid waste (leachate) from two landfill sites in India, finding polyethylene and polypropylene as the most common types. Controlled landfills with treatment systems removed some microplastics, but significant amounts still escaped into the surrounding environment. The findings highlight landfills as an overlooked source of microplastic pollution that can contaminate nearby soil, rivers, and groundwater used by communities.
