Microplastics are pollutants of serious environmental and public health concern. Although predominantly known to occur in biological matrices, emerging scientific evidence has indicated that they can also fecal matter. Animal manure, both raw treated, is usually applied on farmlands as organic fertilizer, serving an entry point microplastic particles into agricultural soil. The present study analyzes the literature occurrence microplastics (sources analytical methods detection livestock poultry manure), their toxicodynamic, toxicokinetics endpoints farm animals. Based studies examined herein, there a lack harmonization sampling, digestion, extraction procedures for animal manure. abundance was 9.02 × 102 ± 1.29 103 particles/kg-1 pig, 7.40 101 cow, 0 5000 particles/kg−1 sheep, 129.8 82.3 particles/g−1 (0.1298 particles/kg) chicken have been found manure were primarily ingested from microplastics-contaminated feed plastic mulching film attached crop residues. However, other likely sources (e.g., water, soil, air) need be studied carefully. Despite limited fate weight currently available shows exhibit different characteristics during treatment previous all based composting experiments. Therefore, research required profound sense better understanding influence physicochemical properties (shape, size, type, composition) treatment. Moreover, exposure animals revealed several toxicological effects but more needed clearly understand dose-response relationship, absorption, distribution, metabolism, elimination mechanisms with respect factors (microplastic sizes, shapes, polymers, types additive, co-contaminants).

Microplastics contamination in fish feeds: Characterization and potential exposure risk assessment for cultivated fish of Bangladesh

Heliyon, Journal Year: 2023, Volume and Issue: 9(9), P. e19789 - e19789

Published: Sept. 1, 2023

Fish feed is becoming an increasingly vital source of nourishment for farmed fish, which are mainly coming from marine fish and agricultural sources. Anthropogenic particles, such as microplastics, abundant in both byproducts that utilized to make feed. This study investigated whether could be a microplastic contamination, revealed 20 weeks adult tilapia might consume up 268.45 ± 1.438 particles via where finisher type feeds were found mostly contributory this number. The microplastics initially observed with stereomicroscope FESEM-EDS. Polymeric composition was determined polypropylene (PP), nylon-6 (NY-6), polyethylene terephthalate (PET), polystyrene (PS), polyvinyl alcohol (PVA), (PE), high- low-density (HDPE, LDPE), ethylene vinyl acetate (EVA), polycarbonate (PC), poly (PVAc), urethane (PU) chloride (PVC) by FTIR. Results also the size all ranged 14 μm 4480 μm, 550 45.45 11,600 56.1 particles/kg FESEM-EDS data demonstrated overlook surface along attachment heavy metals onto Pb, Ni, Co create additional health risks.

Contamination, morphological and chemical characterization, and hazard risk analyses of microplastics in drinking water sourced from groundwater in a developing nation

Frontiers in Environmental Science, Journal Year: 2024, Volume and Issue: 12

Published: May 24, 2024

Groundwater (GW) plays a crucial role as the primary source of potable water in numerous developing nations. However, increasing presence microplastics (MPs) represents concealed danger, threatening activities that guarantee safe drinking these countries. Despite this, there is limited awareness about widespread existence MPs regions world. In this study, we investigated contamination levels, distribution, morphological characteristics, chemical composition, and associated public health risk groundwater samples from six coastal districts Bangladesh using stereomicroscopy Fourier transform infrared spectroscopy (FTIR). were prevalent at all sampling stations, with average concentrations 24.63 ± 16.13 items/L range 4–75 items/L. The majority (97.6%) fibers, indicating likely origin fabric disintegration during drying, washing, discarded fishing nets, personal care items, municipal waste. Smaller-sized (<0.5 mm), transparent violet-colored, predominantly observed. Additionally, FTIR confirmed plastic polymers, including low-density polyethylene (LDPE), high-density (HDPE), ethylene vinyl acetate (EVA), terephthalate (PETE). high visibility observed or focus given for PETE, PE was found to be abundant. These are thought have come runoff agricultural fields, seeping landfills where trash disposed of, synthetic fabrics, inappropriate product disposal. Estimated dietary intake recorded 1.85 particles/person/day (i.e., 675 particles/year), suggesting possible consumers. Hazard analyses based on polymeric score revealed diverse risks polymer PETE medium other e.g., HDPE, LDPE, EVA 39%, 31%, 17%, respectively, showing minor human studied sources. This first study regions, findings will valuable identifying sources, implementing control measures, shaping policies, safeguarding against pollution.

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.
