AB  - Mevcut araştırmalardan elde edilen mikroplastik konsantrasyonları, çoğu zaman gerçekçi olmayan derecelerde yüksek değerler içermekte veya metodolojik farklılıklar nedeniyle kıyaslamayı zorlaştıran eksiklikler barındırmaktadır. Bu durum, mikroplastiklerin kirlilik seviyelerinin sınıflandırılması ve risk faktörlerinin belirlenmesi için daha kapsamlı ve standart yaklaşımlara olan ihtiyacı ortaya koymaktadır. Ancak mikroplastiklerin boyut, şekil, yoğunluk ve kimyasal bileşim açısından geniş bir çeşitliliğe sahip olması ve doğal parçacıklarla birleşerek çok boyutlu yapılar oluşturması, kapsamlı bir risk değerlendirme çerçevesinin geliştirilmesini zorlaştırmaktadır. Bu bağlamda, bu derleme çalışmasında, mikroplastiklerin sucul ekosistemler üzerindeki mevcut ve potansiyel risklerini daha sistematik bir şekilde değerlendirebilmek amacıyla kullanılan ve/veya gelecekte kullanılabilecek olan polimer risk indeksi, kirlilik yük indeksi, potansiyel ekolojik risk indeksi, mikroplastik kirlilik indeksi ve çevresel durum indeksi ele alınmıştır. Söz konusu indekslerin yaygın kullanımı, literatürdeki verilerin çevresel etkilerinin değerlendirilmesi ve etkili yönetim stratejilerinin geliştirilmesi için bir çerçeve oluşturacak; ayrıca mikroplastiklerin kirlilik seviyelerinin küresel ölçekte daha tutarlı bir şekilde yorumlanmasını mümkün kılacaktır.

N2  - Microplastic concentrations reported in current studies often include unrealistically high values or show inconsistencies that make comparison difficult due to methodological differences. This underlines the need for more comprehensive and standardized approaches to classify pollution levels and identify risk factors associated with microplastics. However, the wide diversity in size, shape, density and chemical composition of microplastics, as well as their ability to bind with natural particles and form complex structures, poses significant challenges to the development of a comprehensive risk assessment framework. In this context, this review discusses the polymer risk index, pollution load index, potential ecological risk index, microplastic pollution index, and environmental condition index, which are currently used or could be used in the future to systematically assess the existing and potential risks of microplastics in aquatic ecosystems. The broad application of these indices will contribute to creating a framework for assessing the environmental impacts of data in the literature and to develop effective management strategies. Furthermore, it will enable a more consistent interpretation of microplastic pollution levels on a global scale.
