Summary: This article reviews independent methods for estimating local greenhouse gas emissions, discusses the strengths and weaknesses of different approaches, and explores the challenges in comparing these methods. The authors suggest developing cross-walks between process-based methods and methods attributing CO2 to sources, and emphasize the importance of pooling data streams for better decision support resources. Regression is seen as a promising method for source attribution due to its ability to control confounding emissions and quantify uncertainty.

Summary: This study evaluated the spatial distribution and seasonal variation of trace metal contamination in surface water samples of the Joanes River in Brazil. Different levels of metals were observed between dry and rainy seasons. However, the analysis indicated that the pollutants pose little or no health risk for adults and children over a lifetime of exposure.

Summary: The HPLC method is widely used in pharmaceutical analyses, but careful evaluation of measurement uncertainty is necessary to fully understand its characteristics. Studies on uncertainty estimation in chromatographic methods using the Eurachem/Citac guide show diverse approaches. A comparison between the four most commonly used GUM mathematical models for estimating HPLC technique uncertainty was conducted, revealing significant differences that may lead to confusion in reporting measurement results and decision-making. Alternative approaches, such as the total error approach or ISO 11325, are suggested to check the ISO-GUM method's calculation of measurement uncertainty.

Summary: Achieving ultimate precision for multiple parameters simultaneously in quantum physics is a challenging task due to the Heisenberg uncertainty principle. This study proposes a criterion for multiparameter estimation that offers a possible solution by increasing the variances of parameter generators. Experimental results demonstrate the estimation of spatial displacement and angular tilt of light simultaneously, achieving precisions of 1.45 nm and 4.08 nrad. These findings provide insight into the role of the Heisenberg uncertainty principle in multiparameter estimation and contribute to quantum metrology applications.

Summary: This paper investigates the impact of different sources of variability in stochastic ground motion models on the estimation of engineering demand parameters (EDPs). The authors propose a stochastic kriging framework to approximate the EDP distribution by utilizing a database of EDP estimates for different input parameters and stochastic sequences. They also explore an alternative formulation where some or all of the ground motion parameters are considered as part of the stochastic uncertainty in the excitation description.

Summary: Hydrological models continue to be uncertain due to various factors such as input data, calibration, model structure, and parameters. Different methods for uncertainty analysis are categorized into six broad classes, but there is limited application for structural uncertainty. Further research is needed to improve computational efficiency, address various sources of uncertainty, enhance applications in environmental changes and human-natural-hydrological systems, and make it easier for practitioners to apply uncertainty analysis.

Summary: This study focused on the genotoxicity of pharmaceuticals from different therapeutic groups, both in mixtures and individual solutions, under different environmental conditions. The results showed that the addition of inorganic ions mainly reduced genotoxicity, while changes in the pH of pharmaceutical solutions significantly affected genotoxicity. Synergistic interactions were more commonly observed among mixtures.

Summary: This study presents methods for assessing the health quality of products containing betalains, comparing data on phytochemical composition of beetroot cultivars using various techniques. Identified that betalain contributes about 50% to the antioxidant activity in red beetroot. Photometric measurements are recommended for simple analysis of betacyanin and betaxanthin content, while liquid chromatography techniques provide more precise information. The combination of liquid chromatography with high-resolution mass spectrometry is recommended for more detailed metabolomics studies, identifying sixty-four phytochemicals in beetroot samples.

Summary: The study demonstrates the significant impact of interactions between common food flavonoids on their electrochemical properties and bioactivities. Mixtures of flavonoids show enhanced antioxidant properties compared to individual components, with a synergistic effect observed in both chemical and cellular tests. In cellular tests, the mixtures exhibit properties of a new substance rather than those of individual components, stimulating cell growth.

Summary: Biosorption using phosphorylated hazelnut shell waste (FHS) is a promising method for lithium removal and recovery. This study investigated the performance of a continuous-flow packed-bed column system using FHS for ultra-low level lithium removal. The results showed that the lihium biosorption capacity of the FHS column was unaffected by the bed height, but decreased with increasing flow rate.

Summary: In this study, an ionic covalent organic framework (iCOF) surface grafting monolithic sorbent was prepared for in-tube solid-phase microextraction (SPME) of aristolochic acids (AAs) in various samples. The density of quaternary ammonium ions in the iCOF was modulated for enhanced adsorption of AAs. The iCOF surface grafting monolithic sorbent was confirmed by different means. Several operating conditions were optimized to develop the online in-tube SPME-HPLC method, which showed good linearity, low limits of detection, and high recoveries for AAs in serum samples. This study presents a feasible approach for the application of COF-based monolithic sorbents in sample preparation.

Summary: A chitosan-alginate sponge with multiple cross-linking networks was developed for adsorption and enrichment of anionic dyes from food samples. The sponge showed better three-dimensional network structure, mechanical behavior, and stability compared to pure chitosan and alginate sponges. The adsorption performance and selectivity of the sponge were systematically studied, and it maintained high adsorption capacity and selectivity for anionic dyes. The sponge also showed satisfactory reusability and was successfully combined with high-performance liquid chromatography for the enrichment and detection of anionic dyes in candy and cocktail samples.

Summary: Analysis of in vivo exposure to traditional Chinese medicine using mass spectrometry is helpful for identifying effective ingredients and developing new drugs. This study focused on Forsythia suspensa (Lian Qiao) and used metabolomics technology to explore its in vivo exposure. By comparing the differences before and after administration, a complete set of nontargeted analysis strategies for TCM exposure was established. The study identified 393 Lian Qiao-related chemical components in mice after administration, including prototypes and metabolites. This study provides a reference for research on the active ingredients of Lian Qiao in vivo.
