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
This review examines microplastic contamination in landfill leachate, the liquid that drains from landfills and can contaminate groundwater and surface water. Landfills are major reservoirs of plastic waste that generate microplastics through physical and chemical breakdown, representing a significant but often overlooked contamination pathway.
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.
Emerging contaminants in biosolids: Presence, fate and analytical techniques
Researchers reviewed how "emerging contaminants" — including pharmaceuticals, PFAS (forever chemicals), flame retardants, and microplastics — behave in sewage sludge (biosolids) and wastewater treatment plants, and how they can transform into potentially more toxic breakdown products. The review evaluated detection methods and called for better regulation and advanced analytical tools to track these pollutants as they move through water treatment systems and into the environment.
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 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.
Perfluoroalkyl and polyfluoroalkyl substances in sewage sludge: challenges of biological and thermal treatment processes and potential threats to the environment from land disposal
This review summarizes data on PFAS (per- and polyfluoroalkyl substances, also known as 'forever chemicals') found in sewage sludge, which is commonly spread on farmland. Current biological and thermal treatment methods struggle to fully remove these persistent chemicals from sludge. While focused on PFAS rather than microplastics, the findings are relevant because both contaminants accumulate in sludge and enter the food chain when that sludge is applied to agricultural soil.
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.
Soluble Microbial Products and Perfluorinated Compounds in Wastewater Treatment
This study examines the presence of soluble microbial products and perfluorinated compounds (PFAS) — highly persistent 'forever chemicals' — in wastewater treatment plants. PFAS co-occur with microplastics in water systems and are similarly resistant to conventional treatment, representing compounding contamination challenges for drinking water safety.
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.

The unheeded inherent connections and overlap between microplastics and poly- and perfluoroalkyl substances: A comprehensive review
This review reveals the overlooked connection between microplastics and PFAS (forever chemicals), showing that these two widespread pollutants often come from the same products and interact in the environment. Microplastics can absorb PFAS onto their surfaces and transport them through water systems, potentially increasing exposure for aquatic organisms and humans. Understanding this overlap is important because the combined effects may be more harmful than either pollutant alone.
Poly- and Perfluoroalkyl Substances (PFAS): Do They Matter to Aquatic Ecosystems?
This review examines PFAS, the persistent 'forever chemicals' widely used in consumer products, and their growing threat to aquatic ecosystems. Evidence indicates that PFAS accumulate in aquatic organisms, disrupt hormones, and can alter how other pollutants behave in the environment. The research is relevant to microplastic concerns because PFAS are commonly found in plastic products and can leach from microplastics into water.

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.
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.
Unveiling the Truth of Interactions between Microplastics and Per- and Polyfluoroalkyl Substances (PFASs) in Wastewater Treatment Plants: Microplastics as a Carrier of PFASs and Beyond
Researchers discovered that microplastics in wastewater treatment plants act as carriers for PFAS (forever chemicals), absorbing them from the water and potentially releasing them back into the environment. Commercial plastics were found to leach even more PFAS than environmental samples, with some chemicals releasing more than was originally absorbed. This dual role of microplastics as both carriers and sources of forever chemicals means they could significantly increase human exposure to these persistent, harmful substances.
