Mikro/Nanoplastiklerin Ekotoksikolojik Değerlendirilmesindeki Bilgi Eksikliklerinin Sucul Ekosistem Anahtar Türleri ile Belirlenmesi

Abstract

Son yıllarda sucul alanların mikro/nanoplastikler (M/NP) tarafından kirlenmesi, giderek artan bir endişe haline gelmiştir. Bu durum hem su hem de kara ekosistemlerini aynı anda tehdit etme ve etkileme potansiyeline sahiptir. Bu nedenle, M/NP'lerin toksisitesini belirlemek için son birkaç yıldır kapsamlı araştırmalar yürütülmüştür. Bu makale, sosyal ağ analizini bibliyometri ile entegre ederek Daphnia magna üzerindeki M/NP'lerin toksisitesi hakkındaki küresel bilimsel literatürü incelemiştir. Çoğunluğu akademik dergi makaleleri olmak üzere toplam 100 yayın indirilmiş ve analiz edilmiştir. Ağ haritaları ve grafikler, anahtar kelimeler, ülkeler ve dergiler arasındaki korelasyonları göstermiştir. Ayrıca, mevcut araştırma eğilimlerini ortaya koymak için M/NP'lerin türü, boyutu ve maruz kalma süresi de değerlendirilmiştir. Sonuçlar, PS ve PE'nin çoğu toksisite çalışmasında kullanılan birincil polimer türleri olduğunu göstermektedir. Çin ve Almanya'daki araştırmacılar büyük katkı sağlamıştır. En fazla araştırma makalesi Çevre Kirliliği Dergisi (Journal of Environmental Pollution) tarafından yayınlanmıştır. En iyi yayın yapan ülkeler ve en çok atıf alan yayınlar ve yazarlar muhtemelen hem mikroplastik hem de nanoplastik araştırmalarında standardizasyonun önünü açacaktır.

Identifying Knowledge Gaps on Ecotoxicological Assessment of Micro/Nanoplastics with Aquatic Keystone Species

Abstract

The pollution of aquatic environments by micro/nanoplastics (M/NPs) has been a growing public concern in recent years. This situation has the potential to threaten and affect both aquatic and terrestrial ecosystems simultaneously. Therefore, extensive research has been conducted over the past few years to determine the toxicity of M/NPs. This article investigated the global scientific literature on M/NPs’ toxicity on Daphnia magna by integrating social network analysis with bibliometrics. A total of 100 publications were downloaded and analyzed with the majority being academic journal articles. Network maps and graphics displayed the correlations between keywords, countries, and journals. Moreover, the type, size, and exposure time of M/NPs were also evaluated to expose current research trends. The results demonstrate that PS and PE are the primary polymer types employed in most toxicity studies. Researchers in China and Germany have provided a great contribution. The Journal of Environmental Pollution published the highest number of research articles. The top publishing countries and the top-cited publications and authors will likely pave the way for standardization in both microplastic and nanoplastic research.
