Resumen:
The composition and the interaction of the suspended particulate matter (SPM) withmetal ions, along with the presence and characteristics of microplastics, were analyzedfor the first time in the water column of the inner zone of Bahía Blanca Estuary duringwinter (June, July, and August) 2019. Surface analysis techniques (Scanning ElectronMicroscopy combined with Energy Dispersive X-Ray Spectroscopy, X-RayPhotoelectron Spectroscopy, and X-Ray Diffraction) were employed to obtain an indepth characterization of the particulate matter, suggesting the presence of Fe in oursamples, with a mixture of Fe3+/Fe2+ oxidation states. Microplastics ranged inconcentrations between 3 and 11.5 items L-1, with an average of 6.50 items L-1(S.E:±4.01), being fibers the most abundant type. Infrared Spectroscopy suggests thatthese fibers correspond to semi-synthetic cellulose-based and poly(amide) remains. Weconcluded that the SPM is a significant vehicle for metals which might have adverseeffects on marine organisms.
