Microplastics in FLOW: Seasonal Patterns in Major Latvian Rivers

Research Square (Research Square), Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 5, 2025

Rivers are considered key pathways for microplastics, transporting these pollutants from inland sources to marine environments. In this study, we investigated the seasonal fluctuations of microplastics in surface waters four major Latvian rivers (Daugava, Lielupe, Gauja, and Salaca) that flow into Gulf Riga. Sampling was conducted spring 2022 summer 2023 represent distinct environmental conditions. Using a Manta net (100 µm mesh size) samples were collected triplicate analysed microplastic concentration, shape, size, colour, polymer composition. Microplastic concentrations ranged 0.63 132.88 particles/m³, with highest levels observed River Salaca. Fibres fragments predominant shapes, polyethylene, polypropylene, ethylene propylene diene monomer being most abundant polymers. We found significant spatial variations some rivers, Salaca showing extreme fluctuations. However, overall, no correlation between suspended material river discharge variables. Replicate sampling revealed variability samples, highlighting need include replicas. These findings highlight complexity pollution dynamics careful consideration factors when assessing contamination. This article is first contribute data on growing pool information contamination waterways.

Microplastics in the Mississippi River System during Flash Drought Conditions

Environments, Journal Year: 2024, Volume and Issue: 11(7), P. 141 - 141

Published: July 3, 2024

The Mississippi River System is of great ecological and economic importance, making it crucial to monitor contaminants within it. While nutrient pollution well studied, there are little data on microplastics (MPs) in the (MSRS), especially during drought conditions. Herein, we characterize MP from seven sites across MSRS both flash non-drought periods using FTIR microspectroscopy (µ-FTIR). Additionally, evaluate impact multiple water level conditions polymer composition five time points at a single sampling site. Of all MPs identified, polyethylene terephthalate (PET, 22%), resin (17%), (PE, 10%) were most abundant polymers. Average concentrations ranged 16 381 MPs/L sites, with no significant difference concentration between Irregular particles common morphology, falling lowest size range measured (30–100 μm). Drought condition had (p < 0.001) composition, polymers strongly correlated mostly fluoropolymers. For site, differed, but not significantly, timepoints. These results demonstrate complex relationship condition, also highlight importance fully characterizing environmental studies.

Pollution of Beach Sands of the Ob River (Western Siberia) with Microplastics and Persistent Organic Pollutants

Journal of Xenobiotics, Journal Year: 2024, Volume and Issue: 14(3), P. 989 - 1002

Published: July 25, 2024

Microplastics (MPs) in aquatic environments can be associated with various substances, including persistent organic pollutants, which add to the problem of plastic ecotoxicity. The abundance 1-5 mm microplastics and concentrations particle-adsorbed organochlorine pesticides (OCPs) polychlorinated biphenyls (PCBs) sandy sediments from three beaches recreational areas along upper Ob River Western Siberia were assessed. MP pollution levels beach sands ranged 24 ± 20.7 104 46.2 items m
