Summary: This study investigated the contamination of several popular brands of Iranian table salts and sugars by microplastics (MPs). MPs were detected in all samples, with average amounts observed at 55.2 +/- 43.7 MP/kg for salt and 57.7 +/- 20.6 particles/kg for sugar. Most MPs were in fragment form (78.57% and 95.8% for salts and sugars, respectively) rather than fiber form (21.43% and 4.1%). Polyethylene (PE) and polypropylene (PP) were identified as the most likely polymers. The maximum annual exposure of MPs through salts and sugars was estimated for adults and children. Based on these findings, it can be concluded that MPs can enter the food chain and potentially impact human health.

Summary: This Review examines the properties of microplastic particles and discusses methods of assessing the risks they pose to humans and the environment. Microplastic particles are widespread in the environment and can be found in the air we breathe and the food we eat. The lack of a risk assessment framework that considers the multidimensionality of microplastic particles compared to natural particles is a key challenge. This article reviews current understanding of microplastic characteristics and effects and proposes a method for quantifying exposure and effect thresholds using probability density functions.

Summary: We found that the native moss Hypnum cupressiforme can serve as a biomonitor for atmospheric microplastics (MPs). Moss samples from seven different sites in Campania, southern Italy, were collected and analyzed for the presence of MPs using standard protocols. MPs were found in moss samples from all sites, with fibers being the most abundant fraction of plastic debris. Moss samples from sites closer to urban areas had higher numbers of MPs and longer fibers, indicating a continuous influx of MPs from nearby sources. The size distribution of MPs showed that sites with lower MP deposition levels and higher altitude had smaller size classes.

Summary: This study investigated microplastic pollution for the first time in water, sediment, and fish samples from the Sundarbans region in Bangladesh. The results showed that all analyzed samples contained microplastics, with an average of 2.66 x 103 particles/L in water samples and 1.57 x 105 particles/kg in sediment samples. The gastrointestinal tract of the fish species O. pama and H. nehereus had the highest accumulation of microplastics. Most of the particles were smaller than 1 mm, and black-colored particles were dominant. The analysis revealed the presence of seven polymer types, with polyamide being the most abundant. SEM analysis showed the morphology of plastic samples and adsorbed particles on their surface, and the spatial distribution of microplastics indicated higher levels in areas with greater human intervention. Therefore, this study demonstrates that the Sundarbans mangrove forests are heavily contaminated with microplastics, and the local fisheries can be a potential source of human exposure to these pollutants.

Summary: Network intrusion detection systems (NIDSs) are vital for computer network security, with anomaly-based automated detection mechanisms outperforming others significantly. However, handling large amounts of data remains a challenge for anomaly-based NIDS development. In this research, we propose a hybrid model that combines machine learning and deep learning to enhance detection rates and ensure dependability. Our method employs SMOTE for data balancing and XGBoost for feature selection, resulting in excellent performance on KDDCUP'99 and CIC-MalMem-2022 datasets, achieving accuracy of 99.99% and 100% respectively, without overfitting or Type-1 and Type-2 issues.

Summary: Plastic pollution is a widespread issue that threatens agroecosystems. Recent data has highlighted the potential impact of micropollutants from compost, emphasizing the need to understand their distribution, characterization, fate/transport, and potential risks. Microplastics (MPs) in compost can reach concentrations of thousands of items/kg, with fibers, fragments, and films being the most common. Various synthetic polymers, such as PE, PP, PET, PS, PVC, PES, and AP, have been widely used in plastic items. MPs are emerging pollutants that can transfer potential pollutants from compost to soil. Microorganisms and biochar play a crucial role in composting, and stimulating free radical generation can enhance MP degradation. Future recommendations were discussed to reduce ecosystem risks and health challenges.
