Changes in Fluorescence of Aquatic Dissolved Organic Matter Induced by Plastic Debris

Materials, Journal Year: 2025, Volume and Issue: 18(7), P. 1602 - 1602

Published: April 1, 2025

Water contamination with plastic materials represents one of the most pressing environmental problems that modern world is facing. In this context, present paper aims to investigate influence fluorescent dissolved organic matter (FDOM) released by on aquatic bacterial fraction and evaluate efficiency fluorescence spectroscopy in identifying FDOM freshwater. To purpose, river tap water samples were contaminated a controlled manner laboratory, quality parameters occurrence for these determined using standard physico-chemical characterization methods: spectroscopy, dynamic light scattering, flow cytometry. The results revealed debris influenced dissolved-particulate continuum, also affecting cell proliferation both samples. study highlights impact should not be taken lightly, while proved an effective method presence various origins.

Aged Polystyrene Microplastics Accelerate the Photo-Reduction of Chromium(VI)

Water, Journal Year: 2025, Volume and Issue: 17(7), P. 1102 - 1102

Published: April 7, 2025

Microplastics (MPs) and hexavalent chromium (Cr(VI)) are typical environmental pollutants, yet their interactions in aquatic systems remain poorly understood. This study investigates the mutual influence between Cr(VI) both virgin aged polystyrene microplastics (PS-MPs) under light conditions. Concentration kinetics revealed that total concentration remained stable across all systems, while concentrations decreased over time, indicating PS-MPs accelerate reduction of to Cr(III). Conversely, it had been found promoted aging PS-MPs, this was evidenced by an increase surface roughness generation oxygen-containing functional groups. led a rise O/C ratio carbonyl index, providing additional evidence for PS. Two-dimensional correlation spectroscopy (2D-COS) elucidated exposure, order group alterations PS exhibited opposite trend. Additionally, three-dimensional fluorescence distinct changes characteristics leached substances from pristine PS, with without Cr(VI), dark These results furnish innovative understandings behavior risks associated co-occurrence MPs heavy metals, highlighting complex interplay environments.
