In last 10 years, the interest about presence of microplastics (MPs) in environment has strongly grown. Wastewaters function as a carrier for MPs contamination from source to aquatic environment, so knowledge fate this emerging contaminant wastewater treatment plants (WWTPs) is priority. This work aims review influent (WW) and effectiveness treatments conventional WWTPs. Moreover, negative impacts on management processes have been also discussed. The focuses possible approaches tackle enhancing Based literature results, despite WWTPs are not designed removal WW, they can effectively remove (up 99 % some references).

Unveiling the mechanism of micro-and-nano plastic phytotoxicity on terrestrial plants: A comprehensive review of omics approaches

Environment International, Journal Year: 2025, Volume and Issue: 195, P. 109257 - 109257

Published: Jan. 1, 2025

Micro-and-nano plastics (MNPs) are pervasive in terrestrial ecosystems and represent an increasing threat to plant health; however, the mechanisms underlying their phytotoxicity remain inadequately understood. MNPs can infiltrate plants through roots or leaves, causing a range of toxic effects, including inhibiting water nutrient uptake, reducing seed germination rates, impeding photosynthesis, resulting oxidative damage within system. The effects complex influenced by various factors size, shape, functional groups, concentration. Recent advancements omics technologies such as proteomics, metabolomics, transcriptomics, microbiomics, coupled with emerging like 4D omics, phenomics, spatial single-cell offer unprecedented insight into physiological, molecular, cellular responses exposure. This literature review synthesizes current findings regarding MNPs-induced phytotoxicity, emphasizing alterations gene expression, protein synthesis, metabolic pathways, physiological disruptions revealed analyses. We summarize how interact structures, disrupt processes, induce stress, ultimately affecting growth productivity. Furthermore, we have identified critical knowledge gaps proposed future research directions, highlighting necessity for integrative studies elucidate pathways toxicity plants. In conclusion, this underscores potential approaches MNPs-phytotoxicity develop strategies mitigating environmental impact on health.

Occurrence, quantification and characterisation of microplastics in Godavari River, India

Case Studies in Chemical and Environmental Engineering, Journal Year: 2023, Volume and Issue: 8, P. 100542 - 100542

Published: Nov. 8, 2023

One of the difficult and well-known pollutants that has a negative impact on human health is Microplastics (MPs). This study's primary goal to present state our understanding evidence, quantification, origin, effects MPs in Godavari River. According quantitative analysis investigation (digestion, separation, filtration, characterization), mean MP concentration river was found be 3.9 items/L (3900 Items/m3). were at all six sites, with concentrations ranging from 6.5 2.2 (6500–2200 items/m3). The most prevalent shape fiber (81.5 %), followed by foam (13.2%), fragments (4.4%), film (0.7%). colors observed blue (26%), Transparent (25%), pink (17%), yellow (9%), black (8%), white (6%), green (3%), red (2%), violet From chemical characterization ATR-FTIR, polymers detected polypropylene (PP), high-density polyethylene (HDPE), low-density (LDPE), (acrylonitrile butadiene styrene) ABS, EVA, (polystyrene) PS, nylon. Urban areas have higher than less populated areas. Through direct or indirect consumption, River may risk agriculture, living beings. current study adds pollution provides baseline data can used assess precise mitigation.

Vertical distribution of microplastics in an agricultural soil after long-term treatment with sewage sludge and mineral fertiliser

Environmental Pollution, Journal Year: 2024, Volume and Issue: 356, P. 124343 - 124343

Published: June 7, 2024

Sewage sludge applications release contaminants to agricultural soils, such as potentially toxic metals and microplastics (MPs). However, factors determining the subsequent mobility of MPs in long-term field conditions are poorly understood. This study aimed understand vertical distribution soils amended with sewage comparison conventional mineral fertiliser for 24 years. The depth-dependent MP mass number concentrations, plastic types, sizes shapes were compared organic carbon provide insights into transport-limiting factors. Polyethylene, polypropylene polystyrene concentrations screened down 90 cm depth via pyrolysis-gas chromatography/mass spectrometry. additional sizes, analysed 40 using micro-Fourier transform-infrared imaging. Across all depths, numbers twice 8 times higher when was applied, a share textile-related plastics, more fibres on average larger particles than soil receiving fertiliser.

We hypothesize effect management, ploughing, compactness by bioturbation macropores drives over long time scales. Risk assessment should therefore account considerable displacement avoid underestimating exposure.

Biodegradable Microplastic-Driven Change in Soil pH Affects Soybean Rhizosphere Microbial N Transformation Processes

Journal of Agricultural and Food Chemistry, Journal Year: 2024, Volume and Issue: 72(30), P. 16674 - 16686

Published: July 18, 2024

The potential impacts of biodegradable and nonbiodegradable microplastics (MPs) on rhizosphere microbial nitrogen (N) transformation processes remain ambiguous. Here, we systematically investigated how (polybutylene succinate, PBS) MPs (polyethylene, PE) affect N by determining soil indicators typical Glycine max (soybean)-soil (i.e., red brown soils) systems. Our results show that altered pH dissolved organic carbon in MP/soil type-dependent manners. Notably, soybean growth displayed greater sensitivity to 1% (w/w) PBS MP exposure than since acidified the impeded nutrient uptake plants. In rhizosphere, negatively impacted community composition diversity, weakened (mainly denitrification ammonification), disrupted metabolism. Overall, it is suggested MPs, compared can more significantly influence ecological function plant-soil system.
