Summary: This study assessed microplastic pollution in tropical shallow lakes and found different types and colors of microplastics in lake sediments. The results showed that environmental factors influenced the concentration of microplastics, but there was only a small difference between different regions. The study also suggested that pollution from sanitation, sewage effluents, and solid waste may be the main factors contributing to microplastic contamination.

Summary: The study found the presence of microplastics in water, sediment, and marine biota samples collected from the coastal waters of Mumbai, India, with fibers being the predominant type, and microplastics below 250 microns dominating the samples. Eleven different types of plastic polymers were identified, indicating the transfer of microplastics through the food chain to higher trophic levels, emphasizing the need for further research on interventions to reduce microplastic contamination in fish for human consumption.

Summary: This preliminary study aimed to investigate the short- and long-term effects of remedial dredging on metal contamination, dredging efficacy and ecological status of the Lower Passaic River. The short-term results showed effective reduction of heavy metal concentrations, although they increased in the water column, increasing the risk of bioaccumulation in aquatic biota. On the long-term, metal concentrations increased in surface sediments.

Summary: This study assessed the pollution of microplastics (MPs) in surface sediments of urban, aquaculture, and environmental preservation sites in South Korea, and investigated the historical trend using age-dated core sediments. The abundance of MPs ranked in the order of urban, aquaculture, and environmental preservation sites. An increase in MP pollution and polymer types was observed from bottom to top of cores, and the historical trends of MP pollution reflected local influences. The characteristics of MPs are determined by human activities, and MP pollution should be addressed according to the characteristics of each site.

Summary: Microplastics are small solid polymers with dimensions less than 5 mm that contaminate the environment. Visual count is commonly used for their detection and quantification, but it is time-consuming and prone to errors. To address this issue, a semi-automatic image processing method was developed for quantifying and measuring microplastics on filter membrane substrates, providing accurate and fast results.

Summary: This study assessed microplastic pollution in an urbanized river and found high abundance of microplastics in water and sediment. Water diversion did not reduce microplastic pollution, and the abundance in sediment was not proportional to that in water. Shapes may contribute to microplastic accumulation in fish, with intestine being an ideal tissue to reflect water pollution. All caged fish did not reach high level risks based on pollution load index.

Summary: This study identified that ingestion of atmospheric-deposited microplastics during routine dining/drinking activities is an important exposure pathway, in addition to inhalation. The measured abundances of atmospheric-deposited microplastics were high, with a dominance of amorphous fragments. The ingestion of atmospheric-deposited microplastics through diet was found to be similar to inhalation exposure but significantly greater than direct ingestion from food sources. Simple mitigation strategies can effectively reduce the exposure of atmospheric-deposited microplastics through diet.

Summary: This study examined the sources and contributions of riverine nitrate in the Wen-Rui Tang River in China using various methods. The SIAR model confirmed municipal sewage as the major source of nitrate, with nitrogen fertilizer and soil nitrogen also identified as secondary sources. The study found that the uncertainties associated with different sources varied, and the isotopic composition of the predominant source had the strongest effect on the overall results of nitrate source apportionment.

Summary: Microplastics are a growing concern as they pose a threat to global ecological systems and human health. Recent studies have found microplastics in the remote Tibetan Plateau, which is known as the Third Pole. This article summarizes the evidence of microplastic pollution in different environments of the Tibetan Plateau and assesses their distribution, sources, fate, and ecological effects. The study shows that microplastics are pervasive in both living and non-living components of the Tibetan Plateau, even at high altitudes like Mount Everest. The tourism industry and long-range atmospheric transport are identified as significant sources of microplastic pollution in this sparsely populated area.

Summary: A novel photosensitized living biohybrid was fabricated by inward-to-outward assembly of amine-functionalized carbon dots (NCDs) and polydopamine (PDA) to Shewanella oneidensis MR-1 for high-efficiency microbial-photoreduction of Cr(VI). Modular configurations of NCDs and PDA provided biohybrids with a large electron flux, enhancing electron transport ability and achieving significant reduction capacity for Cr(VI). The NCD-assembled biohybrids showed enhanced Cr(VI) reduction, outperforming conventional microbial technologies for Cr(VI) remediation.

Summary: This study reveals that chronic exposure to PM induces chronic inflammation and development of COPD by dysregulating NAD+ metabolism and subsequent SIRT1 deficiency in pulmonary macrophages. Activation of SIRT1 by resveratrol effectively mitigates PM-induced inflammation and COPD development. Targeting metabolic and epigenetic reprogramming in macrophages induced by PM is a promising strategy for COPD treatment.

Summary: Microplastic contamination in marine ecosystems poses a growing concern due to its trophic transfer and negative effects on marine organisms. This study investigates the transfer and impacts of polystyrene microplastics in an estuarine food chain. The results show that microplastics can be transferred through the food chain, although the transfer rates are low. The exposed organisms exhibit stress responses, suggesting the potential risk of microplastics reaching humans through the food chain.

Summary: This study measured the levels of phthalate metabolites in breast milk collected from mothers in southern China. The results showed that phthalates are still prevalent in the region, and breastfeeding contributes to phthalate intake in infants. However, the levels detected do not pose significant health risks to infants based on dietary exposure. The increasing exposure to certain phthalates calls for further research into their sources and potential risks.

Deterministic processes dominate the assembly of mesopelagic plastisphere microbial communities, while stochastic processes shape the assembly of bathypelagic microbial communities. The relationships between microorganisms in the mesopelagic layer are more complex and stable, with Proteobacteria and Actinobacteriota playing important roles.
