... Machine learning (ML) offers various approaches to create the predictive models such as regression models, artificial neural networks (ANN), decision trees, clustering algorithms, etc. [86]. The ANN model has gained significant attention over the past decades for explaining technical problems in estimation, system control, and optimization [87]. ...

... The percentage of fragments correlated well with salinity (ρ = 0.76, p < 0.05) and the percentage of filaments correlated well with brown MPs (ρ = 0.80, p < 0.05). The association between fragments and salinity potentially indicates the influence of salinity on MP fragment characteristics, as past studies [75,76] showed that salinity affected the transport and interaction of MPs in marine environments. and D90 parameters compared with those measured during winter. ...

... Optical sensors leverage the distinctive optical properties of QDs to identify environmental pollutants and toxins through changes in absorbance or reflectance. [104] Additionally, QDs are used in photodetectors and biosensors, offering high sensitivity and fast response times for medical diagnostics and environmental monitoring. The continued advancement in the synthesis and functionalization of QDs promises to expand their applicability, making them a cornerstone of next-generation sensor technology. ...

... Numerous microalgae species exhibit lipid content within the range of 30%e70% of the dry weight (dw) of their cell biomass. Notably, species such as Arthropsira platensis, Chlorella sp., Botryococcus braunii, Nannochloropsis sp., Neochloris oleoabundans, Porphyridium cruentum, Odontella, and Dunaliella sp. have the capacity to accumulate substantial lipid percentages ranging from 12% to 65.8% (Sun et al., 2019;Gaur et al., 2024). Pavlova lutheri, a fish feed, is known for high polyunsaturated fatty acids (PUFAs) content, while A. platensis demonstrates proficiency in the production and accumulation of stigmasterol, sitosterol, and gamma-linolenic acid (Khanra et al., 2018). ...

... Although data regarding the harmful effects of MP contamination is limited, it is essential to recognise their possible impacts owing to the non-stop growth in their concentration (Kataria et al. 2024;Narwal et al. 2024;Bhardwaj et al. 2024;Bhardwaj 2024). Extensive research has shown the abundance of MPs in aquatic environments; nevertheless, there is a lack of studies on ambient MPs in terrestrial habitats, especially within indoor air contexts (Kacprzak and Tijing 2022;Bhat et al. 2023c). ...

... These materials are then taken to organic waste treatment plants, which are divided into three types: composting, vermicomposting, and biogas. Each of these sub-processes has a specific end product that contributes to the generation of useful resources such as fertilizers [20,[50][51][52][53] and renewable energy (biogas) [54][55][56]. ...

... Methanosarcina thermophila can convert many metabolites produced during the fermentation stage into methane, making them incredibly bene cial for use in mixed-substrate anaerobic digesters. The presence of both Methanobacterium beijingense and Methanosarcina thermophila can improve anaerobic digestion stability by assuring e cient hydrogen and substrate consumption.These methanogens complementary metabolic pathways help maximize methane synthesis from a wide range of substrates.The combined activity of these methanogens increases biogas quality, resulting in increased methane content and lower hydrogen sul de levels, especially when paired with iron and sulfur-oxidizing bacteria [31,32]. ...

... To assess the impacts of MNP addition on soil health, 20 main variables were extracted and grouped into five categories, including crop growth (germination, shoot, root, and grain biomass), animal health (growth, survival, reproduction, and avoidance rate), greenhouse gas emissions (CO 2 , CH 4 , N 2 O, and soil organic carbon), microbial diversity (Shannon, Simpson, ACE, and Chao index), and PTE accumulation (Cd, As, Pb, and Cu concentrations in plant shoot). Traditional soil assessments often focus more heavily on crop growth, but there is now a recognition that soil health includes soil functionality with regard to animal safety, climate change, and human health Williams et al., 2020). Therefore, these additional indicators were selected for soil health assessment. ...
