Summary: Wastewater treatment plants can both receive and release nanoplastics (NPs) and microplastics (MPs). Further investigation is needed to understand the effects of NPs and MPs on nitrogen removal and extracellular polymeric substances (EPS) during the activated sludge process. Results showed that polystyrene NPs (NPS) and 100 mg/L polystyrene MPs (MPS) reduced the specific nitrate reduction rate, leading to nitrate accumulation. This was mainly attributed to the negative effects on functional genes involved in denitrification.

Summary: Carbon to nitrogen (C/N) ratios in wastewater affect the production and composition of extracellular polymeric substances (EPS) in biological treatment processes. This study used stable isotopes to examine the EPS yield and compositional changes in aerobic-anoxic sequencing batch reactors (SBR) with different C/N ratios. The results showed that varying C/N ratios had a more pronounced effect on the production of nitrogenous EPS constituents than their carbon counterparts. This isotope labeling approach can be used to determine mass balances in activated sludge systems.

Summary: This study investigated the effect of temperature on soluble microbial products (SMP) and extracellular polymeric substances (EPS) in wastewater bioprocesses. The results showed that temperature had a greater influence on EPS compared to SMP. A temperature of 60 degrees Celsius was found to be suitable for general extraction purposes. Fluorometry analysis proved to be a sensitive and rapid method for semi-quantitative determination of SMP and EPS constituents, particularly the proteinaceous components. It has positive implications for robust wastewater process control.

Summary: Extracellular polymeric substance (EPS) and extracellular persistent free radicals (PFRs) play important roles in microalgal adaptation to the external environment and aggregate formation. The molecular characteristics of EPS and PFRs in various microalgal species were analyzed, revealing that lignin accounted for the highest proportion of EPS for Cyanophyta and the proportion of lipids was higher for Bacillariophyta. PFRs were detected on the cell surfaces of all microalgae species (excluding Cyclotella sp.), and the intensity of carbon-centered PFRs was correlated with the proportions of humic-like component and lignin.

Summary: This study investigated the secretion of extracellular polymeric substances (EPSs), nutrient removal performance, and microbial community under different concentrations of NaCl in a sequencing batch reactor. The results showed that microorganisms secreted higher levels of proteins and polysaccharides as a protective mechanism under saline conditions. Tightly bound EPS played a crucial role in stabilizing granules. The overall removal rate of chemical oxygen demand (COD) was high, but the removal rate of total nitrogen (TN) decreased with increasing salinity. Low removal efficiency of total phosphorus (TP) was attributed to sludge biomass loss and inhibition of phosphorus-accumulating bacteria activity. Furthermore, the microbial community structure changed with salinity.

Summary: Long-term changes in dissolved organic matter (DOM) quality, particularly in humic-rich raw waters, can significantly impact drinking-water processing. Seasonal variations in DOM quality in standing waters were investigated in a German reservoir using Fourier-transform ion cyclotron resonance mass spectrometry (FTICR MS) and 2D fluorescence. The study revealed that some components of DOM are easily photo-degradable and may act as coagulants in flocculation processes, while others may serve as potential precursors for disinfection byproducts.

The results showed the presence of AOM-related lipid biomarkers and the dominance of anaerobic methanotrophic archaea (ANME)-1 in the studied carbonate samples. The study also reported significant enrichments of various trace elements in the carbonate-hosted lipid fractions. The findings suggest a potential relationship between the type of AOM microbial assemblage and trace element enrichments in carbonate-hosted lipid fractions.

Summary: The market demand for marine-based cosmetics has experienced significant growth in the past decade. Marine resources offer a promising source for the development of novel cosmetic ingredients. However, sustainability is a concern that needs to be addressed in this development. The fisheries industry generates valuable leftover substances that can be extracted to create bioactive ingredients for cosmetics, such as collagen and chitin, which can provide anti-aging, anti-wrinkle, skin barrier, and hair care benefits. This review aims to explore the potential of these marine by-products as active ingredients for cosmetics, as well as discuss the prospect and challenges of sustainable blue cosmetics.

Summary: This study tested the stable isotope analysis of cyantraniliprole (CYN) and chlorantraniliprole (CHL) using compound purification in high-performance liquid chromatography (HPLC). The results showed that there were no significant isotope differences in the standard materials before and after clean-up processing, and the stable isotope differences between soil and plant were negligible. This confirms the potential of stable isotope analysis to quantify pesticide behavior in environments.

Summary: In this study, an integrated framework was validated to effectively manage nitrate loading in complex river systems through quantitative estimation of nitrate sources. The isotopic compositions of nitrates showed different ranges among land-use types, reflecting different nitrate sources within watersheds. Hydrological conditions, such as water discharge, partially controlled total nitrate loads. Sewage transport near urban boundaries showed unique enhancement and increased total nitrate load in downstream areas. The isotopic and model-based nitrate fluxes showed good correlation for urban sources but poor correlation for agriculture-dominated land use.

Summary: There are uncertainties about the combined effects of pollution and impoundment on riverine greenhouse gas emissions. It is debated whether eutrophication can transform downstream estuaries into carbon sinks. This study combined surveys along three impounded rivers in Korea and samplings at estuarine sites to assess the human impacts on CO2, CH4, and N2O distributions. Results showed that pollution generated localized hotspots of GHGs in metropolitan areas, but the highest GHG levels in the upriver areas did not carry over into the estuary. CH4 levels were elevated in eutrophic reaches, indicating enhanced phytoplankton production. The study emphasizes the importance of considering specific pollution sources and impoundments when evaluating GHG distributions and estuarine carryover effects.

Summary: Although many attempts have been made to improve the accuracy of trophic magnification factor (TMF) and biomagnification factor (BMF) for assessing pollutant bioaccumulation, this study suggests an improved BMF (BMF') for mercury bioaccumulation in freshwater fish. The results show that the values of BMF' are generally higher than TMF, indicating that it is a more reliable index for risk assessment. This ecological approach provides novel insights into the behavior and trophic transfer of pollutants like mercury.

By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
