This review examines microplastic contamination in landfill leachate, finding that plastic waste deposited in solid waste sites gradually degrades into microplastics that are transported via leachate into receiving water bodies and agricultural land, while highlighting the limited number of studies on leachate-derived microplastic concentrations, shapes, polymer types, and ecological risks.

Plastiklerin küresel anlamda yüksek üretim ve tüketimi, önemli miktarda plastik atık oluşumuna sebep olmaktadır. Plastik atıkların katı atık düzenli depolama sahalarında bertaraf edilmesi ile, plastik atıklar zamanla bozunarak mikroplastik formuna dönüşmektedir. Depolama sahalarında oluşan sızıntı suları vasıtasıyla mikroplastikler, alıcı ortamlara taşınmakta ve potansiyel bir kirlilik kaynağı haline gelmektedir. Bu sebeple, birçok alıcı su ortamında ve tarım arazilerinde mikroplastik kirliliği meydana gelmektedir. Literatürde, sızıntı suyunda mikroplastik kirliliğinin tespiti için az sayıda çalışma bulunmaktadır. Sızıntı suyunda bulunan mikroplastik kirliliğinin çevresel etkilerinin ortaya konabilmesi için, bu alanda yapılan çalışma sayısının artması gerekmektedir. Bu çalışmada, literatür kapsamında incelenen çalışmalar ile sızıntı suyundaki mikroplastik kirliliği değerlendirilmiştir. İncelenen çalışmalarda, sızıntı sularında mikroplastiklerin örneklenmesi, izolasyonu ve analiz yöntemleri detaylı bir şekilde irdelenmiştir. Sızıntı suyu kaynaklı mikroplastik konsantrasyonları, şekilleri ve başlıca polimer türleri incelenmiş olup mikroplastik kirliliğinin ekolojik riskleri özetlenmiştir.

Leachate from municipal solid waste landfills: A neglected source of microplastics in the environment

AI summary Read the abstract

This review identified municipal solid waste landfills as a significant but neglected source of microplastics in the environment, explaining how physical compression, chemical oxidation, and biological decomposition of buried plastics generate microplastics that migrate via leachate into surrounding soils and water.

Microplastics in Landfill Leachate

AI summary Read the abstract

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.

Microplastics in landfill leachate: Occurrence, health concerns, and removal strategies

AI summary Read the abstract

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 as emergent contaminants in landfill leachate: Source, potential impact and remediation technologies

AI summary Read the abstract

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: Sources, detection, occurrence, and removal

AI summary Read the abstract

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.
