Nehirlerde Mikroplastik Kirliliği ve Hidrodinamik Modellenmesi

Öz

Plastik atıklar, günümüzün en önemli çevresel sorunlarından biri olarak kabul edilmiştir. Bu atıkların kaynaklarının çoğu karasal olduğundan, çalışmalarda tatlı su ve karasal çevreye odaklanılmaktadır. Tatlı su kaynaklarından nehirler ise, denizlere ve okyanuslara mikroplastik taşıyan en önemli kaynaktır. Bu nedenle, nehirlerde mikroplastik kirliliğinin anlaşılabilmesi önemlidir. Bu derleme çalışmada mikroplastikler ve ekosistemlere giriş yolları, nehirlerde mikroplastiklerin akıbeti ve taşınımı ile ilgili yapılan hidrodinamik modellerin öncü çalışmaları incelenmiştir. Mikroplastiklerin nehirlerde taşınımında zamana ve mekana bağlı değişimi tartışılmıştır

Microplastic Pollution and Hydrodynamic Modeling in Rivers

Abstract

Plastic waste has been recognized as one of the most important environmental problems of today. Since most of the sources of these wastes are terrestrial, studies focus on fresh water and terrestrial environment. Rivers, which are one of the fresh water resources, are the most important source of microplastics to the seas and oceans. Therefore, it is important to be able to understand microplastic pollution in rivers. In this review, pioneering studies of hydrodynamic models on microplastics and their entry routes into ecosystems, fate and transport of microplastics in rivers are examined. The temporal and spatial variation of the transport of microplastics in rivers is discussed.
