Abstract

Analyzing particulate plastics, particularly microplastics and nanoplastics, is still a major analytical and methodological challenge due to the time- and resource-intensive laboratory procedures involved. These limitations hinder comprehensive investigations into fate in the environment, transport mechanisms and biological interactions. Although significant progress has been made in the development of analytical methods capable of detecting submicron plastic particles, a better understanding of the relationship between the presence of microplastics and water quality parameters is essential for assessing environmental risks and improving pollution monitoring strategies. This knowledge gap poses a particular challenge for the routine monitoring of microplastics in wastewater treatment plants, where the development of reliable, cost-effective and easily measurable surrogate indicators is essential. To address this problem, the present study systematically analyzed peer-reviewed research papers investigating correlations between microplastic concentrations and water quality parameters in wastewater treatment plants. The aim is to identify promising physico-chemical indicators that can facilitate the routine monitoring of plastic pollutants in treated effluents and influents. The results of this study are expected to contribute to the development of more effective plastic pollution control strategies and support the implementation of robust monitoring protocols that improve the sustainability and operational efficiency of water treatment processes.

Abstract

Mikroplastik ve nanoplastik gibi partikül plastiklerin analizi literatürde yaygın çalışmalar içeriyor olsa da laboratuvar süreçlerinin zaman ve kaynak gerektirmesi nedeniyle günümüzde hala önemli analitik ve metodolojik zorluklar barındırmaktadır. Bu sınırlılıklar, söz konusu plastiklerin çevredeki akıbeti, taşınım mekanizmaları ve biyolojik etkileşimlerine dair kapsamlı araştırmaların yürütülmesini zorlaştırmaktadır. Her ne kadar mikrometrenin altındaki plastik parçacıkların tespiti için çeşitli analiz yöntemlerinde önemli ilerlemeler kaydedilmiş olsa da mikroplastik varlığı ile su kalitesi parametreleri arasındaki ilişkinin daha iyi anlaşılması, çevresel risklerin değerlendirilmesi ve kirlilik izleme stratejilerinin iyileştirilmesi açısından büyük önem taşımaktadır. Bu bilgi eksikliği, özellikle atıksu arıtma tesislerinde mikroplastiklerin rutin olarak izlenmesini güçleştirmekte ve bu bağlamda güvenilir, ekonomik ve kolay ölçülebilir gösterge parametrelerin belirlenmesini zorunlu kılmaktadır. Bu sorunu ele almak amacıyla, bu çalışmada mikroplastik konsantrasyonları ile su kalitesi parametreleri arasındaki korelasyonları inceleyen araştırma yayınları sistematik olarak analiz edilmiştir. Çalışmanın temel hedefi, arıtılmış çıkış suları ve giriş sularında plastik kirliliğinin rutin olarak izlenmesini kolaylaştırabilecek potansiyel fizikokimyasal gösterge parametrelerini belirlemektir. Elde edilen bulguların, plastik kirliliğinin kontrolüne yönelik daha etkili stratejilerin geliştirilmesine katkı sağlaması ve arıtma süreçlerinin sürdürülebilirliği ile işletme verimliliğini artıracak sağlam izleme protokollerinin oluşturulmasına destek vermesi beklenmektedir.
