Identification and quantification of microplastics in surface water of a southwestern Mediterranean Bay (Al Hoceima, Morocco)

Waste Management Bulletin, Journal Year: 2024, Volume and Issue: 2(1), P. 142 - 151

Published: Jan. 11, 2024

In this study, we evaluated the pollution in Al Hoceima Bay (Southwestern Mediterranean, Morocco) by microplastics. Nine stations were investigated 2019, 2020, and 2021, using Manta net microplastics identified quantified with Raman Spectroscopy. The obtained results showed that fibers, fragments, pellets, films predominant types of dominant size ranged from 0.15 to5 mm while 0.3-0.5 was most prevalent 46.97%. Seven colours counting white blue as items recorded. abundance 1-15 items/m3, an average 4.70±4.50 items/m3. Four polymers dominated Polyethylene (67.4%), Polypropylene (23.2%), Polystyrene (7.1%), Terephthalates (2.3%) identified. spatial distribution variable. not related to distance separating potential sources sampled stations. Our study provided initial data on their along Mediterranean coasts Morocco, recommended for future investigations marine basin.

Microfiber prevalence and removal efficiency of textile effluent treatment plants in Bangladesh

Journal of Hazardous Materials Advances, Journal Year: 2024, Volume and Issue: 14, P. 100436 - 100436

Published: May 1, 2024

Bangladesh is one of the hubs textile industry in world; consequently, microfibers are an emerging threat to aquatic ecosystem. Traditional effluent treatment plants (ETPs) might not be capable removing most pollutants like surfactants, dyes, and additives, including microfibers, may a major source microfiber pollution through products ETPs. This study investigated eleven woven, knit, denim industries' ETP abundance removal efficiency. The average (range) found influent, effluent, sludge samples was 615.45 ± 377.52 particles/L (170−1,460), 212.72 80.14 (130−380), 10,545.45 7,989.54 particles/kg (4,400−31,000), respectively. abundant shape fiber, microfibres had sizes between 0 100 μm. Eight distinct colors were samples; black color among all samples, followed by brown blue. studied ETPs showed 23.52% 82.19% rate, which satisfactory for minimizing pollution. Fourier transform infrared (FTIR) analysis revealed that main polymers nylon, ethylene-vinyl acetate (EVA), polyethylene terephthalate (PETE), acrylonitrile butadiene styrene (ABS), cellulose (CA), low-density (LDPE or linear LDPE), high-density (HDPE). contamination factor (CF) load index (PLI), assess ecological risks, moderately very highly contaminated could pose findings would help identify transformative challenges required from industrial sectors improving systems.

Investigation of Removal Efficiency of Microplastics at Different Process Stages of a Wastewater Treatment Plant in the Textile Industry in Southern China

Water, Journal Year: 2025, Volume and Issue: 17(4), P. 574 - 574

Published: Feb. 17, 2025

Wastewater treatment plants (WWTPs) play a crucial role in mitigating microplastic (MP) release to the environment. In this paper, WWTP of textile manufacturing plant Guangdong, China, was investigated identify MP characteristics and effectiveness wastewater within plant. Laser Direct Infrared (LDIR) Liquid Chromatography with Mass Spectrometry (LC-MS/MS) were applied quantify both number mass microplastics effluent where most from three printing dyeing lines. The study further removal efficiency each process industry-owned analysed mechanism step, highlighting limitations detecting eliminating MPs. It is observed that (1) results LDIR LC-MS/MS can be complementary other; (2) concentration influent 1730 n/L by 13.52 µg/L mass; (3) total 99% MPs 67.7% MPs; (4) nine types polymers have been identified influent, which Polyamide (PA) dominating; (5) hydrolysis acidification removed PA most; (6) aerobic tank, sand filter, biological aerated filter (BAF) showed low efficiency; (7) coagulation sedimentation tank had highest PET than any other processes.

Determination of microplastics in municipal wastewater treatment plant effluents and sludge using micro-Raman spectroscopy

Water Emerging Contaminants & Nanoplastics, Journal Year: 2025, Volume and Issue: 4(1)

Published: Feb. 19, 2025

Microplastics (MPs) increase global awareness due to their ubiquity, high concentration levels, and devastating effects on the aquatic environment. Wastewater treatment plants (WWTPs) are recognized as a significant source of microplastics in terrestrial environments, particularly for plastics used personal care products textile fibers from clothing industry. The focus present study was determination MP wastewater sewage sludge samples WWTP Ioannina city, according shape, size, concentration, polymer type. A wet peroxide oxidation (WPO) method using 30% H2O2 0.05 M ferrous (II) solution applied water effluent, while an enzymatic digestion combined with WPO employed eliminate organic matter extract MPs samples. Micro-Raman spectroscopy coupled appropriate software detect quantify microplastic particles. outcomes this showed that most representative shape effluent fragments (66.7% 75%, respectively), followed by fibers, spheres, films. Polyamide (PA), p -acrylic acid (PAA), -acrylamide-co-p (PAM-co-PAA) were abundant polymers (100% frequency detection), -vinyl chloride (PVC), -butyl methacrylate (PBMA), -ethylene (PE), -styrene (PS), -propylene (PP), alcohol (PVA), butyral (PVB) (20%-80% detection). mean five sampling campaigns 5.8 ± 0.6 particles/L secondary effluents 33.3 8 particles/g sludge. This focused monitoring campaign, order better understand occurrence, impact, risks associated WWTPs.
