Spatial distribution and risk assessments due to the microplastics pollution in sediments of Karnaphuli River Estuary, Bangladesh

Scientific Reports, Journal Year: 2022, Volume and Issue: 12(1)

Published: May 20, 2022

Abstract Microplastics (MPs) have become an emerging global pollutant due to their widespread dispersion and potential threats marine ecosystems. However, studies on MPs in estuarine coastal ecosystems of Bangladesh are very limited. Here, we conducted the first study abundance, distribution, characteristics, risk assessment microplastics sediment Karnaphuli River estuary, Bangladesh. Microplastic particles were extracted from sediments 30 stations along estuary by density separation then enumerated characterized using a stereomicroscope Fourier Transform Infrared (FT-IR) spectroscopy. In collected number varied 22.29 59.5 items kg −1 dry weight. The mean abundance was higher downstream left banks whereas predominant shape, colour, size films (35%), white (19%), 1–5 mm (30.38%), respectively. Major polymer types polyethylene terephthalate, polystyrene, polyethylene, cellulose, nylon. found pose risks (low high) with highest occurring at one station near sewage outlet, according results analyses pollution index, index (H), contamination factors, load (PLI). single value PLI, clearly demonstrated that all sampling sites considerably polluted (PLI > 1). H values showed toxic polymers, even lower proportions, possess polymeric hazard scores vice versa. This investigation uncovered new insights status laying groundwork for future research control microplastic management.

The potential for a plastic recycling facility to release microplastic pollution and possible filtration remediation effectiveness

Journal of Hazardous Materials Advances, Journal Year: 2023, Volume and Issue: 10, P. 100309 - 100309

Published: May 1, 2023

With current plastic production and the growing problem of global pollution, an increase improvement in recycling is needed. There limited knowledge or assessment microplastic pollution from point sources such as facilities globally. This pilot study investigates a mixed plastics facility UK to advance quantitative understanding (MP) release receiving waters. Raw wash water were estimate contain counts between 5.97 106 – 1.12 × 108 MP m−3 (following fluorescence microscopy analysis). The mitigation (filtration installed) was found remove majority microplastics >5µm, with high removal efficiencies for >40µm. Microplastics <5µm generally not removed by filtration subsequently discharged, 59-1184 tonnes potentially discharged annually. It recommended that additional smaller prior discharge incorporated management. Evidence suggest it may be important integrate into quality regulations. Further studies should conducted processes.

Distribution and risk assessment of microplastic pollution in a rural river system near a wastewater treatment plant, hydro-dam, and river confluence

Scientific Reports, Journal Year: 2024, Volume and Issue: 14(1)

Published: March 12, 2024

Abstract Rivers are the natural drainage system, transporting anthropogenic wastes and pollution, including microplastics (plastic < 5 mm). In a riverine can enter from different sources, have spatial variance in concentration, physical chemical properties, imposed risk to ecosystem. This pilot study presents an examination of water sediment samples using single sample collection rural Raquette River, NY evaluate hypothesis that distinct locations river, such as downstream wastewater treatment plant, upstream hydro-dam, river confluence, may be higher concentration. general, our results revealed presence high microplastic concentrations plant (in sediments), hydro dam (both sediment), confluence (water sample), compared other sites. Moreover, assessment indicates even with most its basin comprising forested agricultural land, water, at all three polluted (pollution load index, PLI > 1; zone = 1.87 1.68 for respectively), categories between Levels I IV (“minor” “danger”). Overall, stands “considerable” category (PRI 134 113 respectively). The overall objective this was advance understanding dynamics systems, elucidating their introduction point source (wastewater plant), transit through impediment (hydro-dam), release into vital transboundary (confluence Raquette-St. Lawrence Rivers).

The Osun River serves as a source of drinking and domestic water for some communities in State Nigeria, addition to providing "healing water" the worshippers goddess. sacred river has earned status UNESCO world heritage centre worldwide attention it receives, result yearly Osun-Oshogbo worship festival. In this study, an initial investigation microplastic pollution water, sediments fish species was conducted. Abundance microplastics samples, at maximum 22,079 ± 134 particles/litre, represents highest reported so far globally. FTIR analyses revealed seven polymer materials, including acrylonitrile butadiene styrene (ABS) ethylene vinyl acetate (EVA), that have not been commonly environments. Microplastics ranged from 407 244 1691.7 443 particles gastro-intestinal tract (GIT) six analysed, with silver catfish (Chrysichthys nigrodigitatus) having concentration. Levels fishes are higher than those Asia Europe, but similar other plastic hotspots Africa. This study recognizes uncontrolled indiscriminate disposal single-use plastics key factor level river.
