Summary: A novel method based on QuEChERS extraction and ultra-high-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) detection was developed for analyzing 14 mycotoxins in peaches and peach products from China. The method accurately quantified mycotoxins with recoveries ranging from 84.6% to 117.6% and precision below 20%. Six mycotoxins were identified in diseased peaches, while fresh peaches showed no mycotoxin contamination. Peach products had contamination levels below quantitative limits and legal limits.

Summary: Carotenoid pigmentation in salmon can cause matrix effects and affect compound recovery during antibiotic analysis using UPLC-MS/MS. Pigmented salmon showed significant matrix effects and lower percent recoveries compared to non-pigmented salmon. Dispersive SPE clean-up did not improve extraction recoveries, but HLB SPE clean-up reduced matrix effects at the cost of lower percent recovery.

Summary: This study found that bacterial communities in river water and sediment are influenced differently by seasonal variations and anthropogenic activities, with the water bacterial communities also impacted by emerging pollutants. The dominant phyla Proteobacteria and Firmicutes showed adaptability to various affected regions, with associations to antibiotic resistance. Levels of antibiotics, antibiotic resistance genes, and non-antibiotic pharmaceuticals were closely related to bacterial community composition and diversity, indicating their role in shifting bacterial communities.

Summary: The UV/chlorine process is an efficient advanced oxidation process in water treatment. This study evaluated the reaction kinetics and mechanism of nitrobenzene, benzoic acid, and p-chlorobenzoic acid in the UV/chlorine process using theoretical calculations and experimental studies. The results showed that the reactions in the UV/chlorine process are mainly initiated by H-abstraction and addition pathways, with slower reactions initiated by chlorine radicals. The theoretically calculated rate constants were consistent with experimental results.

Summary: The widespread use of various chemicals has led to water pollution, which is a global environmental concern. This study investigated the presence and characteristics of organic chemicals in the North River, South China. It identified 402 different organic chemicals in the river, including industrial chemicals, pharmaceuticals, and pesticides. Some of these chemicals have rarely been reported in surface water before, and some have never been documented in the North River. The study also found significant seasonal variations in the distribution of these chemicals, which could be attributed to wastewater discharge, river dilution, and anthropogenic activities such as pesticide use in agriculture.

Summary: In recent years, there has been growing concern about volatile organic compounds (VOCs) and their potential environmental impact. However, little research has been done on the VOCs pollution caused by insecticide application in agriculture. This study aimed to assess the occurrence of insecticide VOCs in China and discuss the estimation of VOCs emission potentials and actual emissions. Nine insecticide formulations were tested using a thermogravimetric analyzer and a pump-suction photoionization detection gas detector. The results showed significant variation in VOCs emission potentials and actual emissions among different formulations, with temperature, relative humidity, and atmospheric pressure affecting the actual emission ratio.

Summary: This study used an in situ tool, diffusive gradients in thin films (DGT), to investigate the distribution and exchange kinetics of five typical PFAS in four soils. The results showed a nonlinear relationship between PFAS masses in DGT and time, indicating that PFAS were partially supplied by the solid phase in all soils. A dynamic model called DGT-induced fluxes in soils/sediments (DIFS) was used to interpret the results and determine the distribution coefficients for the labile fraction (Kdl), response time (tc), and adsorption/desorption rates (k1 and k-1). The findings suggest that the availability of PFAS in soils is controlled by Kdl, while the release of PFAS from soils may be kinetically constrained, especially for more hydrophilic PFAS.

Summary: In this study, the ecotoxicological effects of Bisphenol 4-[1-(4-hydroxyphenyl)-3,3,5-trimethylcyclohexyl] phenol (BPTMC) on marine medaka embryos were examined. Low concentrations of BPTMC stimulated certain developmental and behavioral effects, while higher concentrations led to inflammatory response and altered heart rate and swimming velocity. BPTMC also affected the concentrations of estrogen receptors, vitellogenin, and endogenous 17 beta-estradiol, as well as transcriptional levels of estrogen responsive genes in the embryos or/and larvae.

Summary: In this study, fulvic acid (FA) was used to modify Co-Fe binary metals (CFO) for peroxymonosulfate (PMS) activation, effectively removing BPF and BPS. The characterization results showed that the modified CFO had smaller particle size, larger specific surface area, and increased active sites. The degradation efficiency of CFO for both BPF and BPS was significantly improved after compound FA, with increased concentration of reactive species.

Summary: Imidacloprid (IMI) and thiamethoxam (THM) exhibit negative effects on parental fish, but their intergenerational effects at environmentally relevant concentrations are still unclear. This study investigates the intergenerational effects by exposing F0 zebrafish to IMI and THM and examining the F1 generations. The results show that IMI and THM affect fecundity, gonadal development, sex hormones, and VTG levels in F0 zebrafish, and also influence sex hormones, heart rate, and spontaneous movement rate in F1 generation.

Summary: Ceramic water filters (CWFs) with lanthanum (La) coating showed enhanced viral removal, exceeding the capacity of commercial CWFs. The increased attachment of virus onto the filter surface, reduction of repulsive energy barrier, and the inactivation nature of La-coated ceramic contributed to the improved viral removal. Both genome damage and protein capsid conformational changes caused viral inactivation by La-coated ceramic. This finding is promising for practical viral removal in developing countries and advances the research on La application for water treatment.
