Summary: In this study, a novel pyrethroid-degrading strain Rhodococcus pyridinivorans Y6 was isolated from contaminated activated sludge. The Y6 strain showed the ability to metabolize multiple pyrethroid pesticides within 36 hours. It was also found that the strain could effectively remove prallethrin from soil and slurry without adverse effects on soil community structure and diversity. Furthermore, a specific gene responsible for the hydrolysis of prallethrin was identified and confirmed.

Summary: This study evaluated the effects of various factors on pesticide analysis results and tested different surface wipe sampling methods for fipronil, permethrin, and delta-methrin. The findings suggest that different wipe media and solvent concentrations can affect the analysis results of these target analytes.

Summary: This study presents an analytical method for the simultaneous analysis of SAs and their transformation products in water samples, and detected all target compounds in three urban rivers in Beijing. Predominant acetyl SAs in the aquatic environment were identified as N-acetylsulfamethoxazole, N-acetylsulfapyridine, and N-acetylsulfamethazine, with high frequencies of hydroxylated SAs and glucuronide-conjugated SAs also being detected.

Summary: This paper proposes an optimal ASP design method considering the unit heterogeneity, determines the optimal test time and sample size by maximizing the determinant of the Fisher information matrix, simplifies the acceptance test problem by using the average degradation rate as the acceptance index, and demonstrates the feasibility of the method through simulation and a real example.

Summary: This study investigated the formation of oxidative products of monoterpenes at vaping temperatures using thermal desorption GC/MS. The majority of formed oxidative products have molecular weights of 134, 150, and 152, and could potentially cause allergic and irritation reactions. Understanding the potential risks and harms of vaping is crucial.

Summary: This study proposes the use of spatio-temporal stratified sampling to evaluate thematic mappings with respect to temporal changes and spatial clustering, and an optimization algorithm is used to determine sample sizes for different strata. Results show that this method leads to the smallest bias in accuracy estimation compared to conventional sample allocation methods.

Summary: This study compared three different techniques for evaluating the indoor protective efficacy of the volatile pyrethroid spatial repellent Mosquito Shield(TM). The results showed that human landing catch and blood-feeding inhibition measurement provided similar estimates of protective efficacy, while CDC light trap underestimated the efficacy.

Summary: This study proposes a spatiotemporal stratified sampling method for multi-temporal land use data, which stratifies the data based on changed and unchanged types and simplifies the strata labels using binary coding. The sample size is determined by proportional allocation and empirical evaluation. Experimental results show that this method increases the sample size of change strata and evaluates the accuracy and area of different types of data effectively.

Summary: Mycelium-bound composites (MBCs) are sustainable materials obtained by growing fungi on a ligno-cellulosic substrate, which have applications in packaging, furniture, and construction industries. This study presents experimental evidence of a biocycle for MBCs in indoor applications and highlights the importance of sustainable coatings in increasing durability while maintaining biodegradability. It paves the way for optimizing the duration of each phase in the biocycle based on the intended application and resource availability.

Summary: This study reviews the antimicrobial transformation products (TPs) in surface water environments and evaluates their potential for promoting antimicrobial resistance (AMR) and their ecological and health hazards. Certain TPs were found to pose a risk of AMR promotion and harm to ecosystems and human health. The study proposes a method for evaluating TP risk based on structural similarity and identifies 13 high-priority TPs.

Summary: Phthalate and alternative plasticizers are among the most abundant indoor pollutants and can directly transfer from source products to dust, with various factors such as Koa, emission parameter and dust layer characteristics influencing the concentration and kinetics of this transfer. Minimizing the use of SVOC-containing products and regular vacuuming are effective strategies to reduce young children's exposure to SVOCs.

Summary: Conventional wastewater treatment systems are ineffective in removing pharmaceutical compounds, which can degrade into unstudied transformation products. This study focuses on the occurrence and degradation of furosemide and its degradation products in different types of wastewater. The results show that furosemide was well degraded in the wastewater treatment plant, but its main degradation products were not detected at increased concentrations. Chlorination and ozonation processes effectively removed furosemide and its degradation products in water from care homes, but resulted in the production of saluamine. This study is the first to identify saluamine and pyridinium of furosemide in real water samples.

Summary: This study evaluates the spatial and temporal variations in trichloramine and trichloromethane concentrations within indoor swimming pools. The results show significant variations in concentration over time, suggesting that the common practice of collecting a single 2-hour air sample does not accurately represent the true exposure and health risks for workers. A new 8-hour sampling strategy or a full-shift strategy is recommended for accurate assessment.

Summary: This study used in vitro assays to determine the bioaccessibility of 14 PFAS in 33 sets of soils and dusts. The results showed that PFAS had higher bioaccessibility in soils compared to dusts, and the addition of a sink increased the bioaccessibility in the test system. The study suggests that the bioaccessibility of PFAS in soils and dusts can be predicted using a limited set of physical chemical characteristics and could inform risk assessment models.
