Soil microplastics – current research trends and challenges: preliminary results of the earthworm <i>Eisenia fetida</i> impact on glitters

Abstract This paper shortly introduces the topic of soil microplastics by presenting a comprehensive review current state art in this field. It focuses mainly on role primary microplastics, particularly glitters, due to their large surface-to-volume ratio. From conclusions about challenges and research directions, after analysis crucial “knowledge gaps “, one can point out lack detailed description influence biota. The earthworms are promising model organisms that may play ecosystems similar bivalves waters. Thus, was enlarged preliminary results studies glitters bioglitters naturally aged milli-Q water with Eisenia fetida . Fourier-transform Infrared (FTIR, microscopy reflectance mode) Raman spectroscopy (780 nm) were used identify subsequent notable changes studied materials. presence polymer (PET) core standard glitter particles is confirmed. In addition, leakage dyes from observed within 9-week experiment. Tested decompose slightly different way. Blue pink pigments had entirely stability as only disappeared without trace under UV light (blu), other remained stable solution, confirmed UV-Vis spectra. nephelometry shows sedimentation turbulent agents environment. presents natural weathering
