Summary: Commercial chlorinated paraffins (CPs) are a significant source of CPs in the environment, with various CP congener groups identified in commercial products through advanced gas chromatography and mass spectrometry techniques. The study suggests that commercial CPs products may contribute to different types of chlorinated paraffins in the environment.

Summary: This study elaborates the comprehensive environmental transformation of short-chain chlorinated paraffins (SCCPs) in a rice seedling exposure system. The selected congener of SCCPs, CP-4, was quickly absorbed, translocated, and phytovolatilized by seedlings. The transformation of CP-4 was mainly attributed to degradation by rhizosphere microorganisms, root exudates, and abiotic factors, with a majority being phytotransformed by rice seedlings. A total of 61 transformation products were identified through complex pathways.

Summary: Short- and medium-chain chlorinated paraffins (SCCPs and MCCPs) have been widely detected in soil environment. Tree bark, as a good matrix for trapping chlorinated paraffins (CPs) in the air, has been less studied for CP pollution, and limited information exists on the air-soil exchange of CPs. In this study, CP congener groups were measured in the surface soils and tree barks from 36 points in the Yangtze River Delta (YRD). The results showed that CPs were concentrated in the Taipu River watershed, which is a textile manufacturing area. The air-soil exchange behaviors indicated that CPs primarily deposit in the environment.

Summary: This study developed a pregnancy physiologically based pharmacokinetic model to characterize fetal permethrin exposure in rats, highlighting the distribution and transfer of permethrin in maternal and fetal tissues, especially in the fetal brain. This work could be applied to estimate prenatal exposure and placental transfer of permethrin in humans using biomonitoring data.

Summary: The development of efficient cathode-side ORR catalysts is crucial for the practical application of fuel cells and ZABs. In this study, a facile and green photochemical method is used to synthesize MnO/N-rGO catalysts with highly catalytical activity and stability. The catalysts exhibit exciting ORR performance in alkaline media and outperform Pt/C-based GDE half-cell and Pt/C + RuO2-based ZABs in terms of overall performance and long-term durability. The synergistic effect between MnO nanoparticles and N-rGO support is the key factor contributing to their enhanced performance.

Summary: The study found that PFASs are associated with preeclampsia and are linked to low birth weight and small for gestational age. The analysis included 82 women with preeclampsia and 169 healthy participants, and measured 15 PFASs in maternal serum. The results showed that PFOA and 6:2Cl-PFESA were associated with higher incidence of preeclampsia, particularly among primiparous women. Additionally, PFOA concentrations were associated with increased blood pressure. Overall, the concentrations of PFASs mixtures were associated with preeclampsia, with PFOA being the largest contributor. There was also a higher risk of low birth weight and small for gestational age with higher PFOA and PFUnDA exposure, although 4:2 FTS and ADONA were inversely associated with these outcomes.

Summary: Traditional solution-based synthesis methods have limitations in fabricating one-dimensional single-crystalline nanostructures. Here, we introduce a growth mechanism based on progressively oriented attachment, which allows the formation of single-crystalline nanowires with elongated length and moderate thickness. These nanowires can be integrated into a wearable device for multidirectional strain sensing with high responsivity and excellent stability.

Summary: A homogeneous manganese-catalyzed cross-coupling reaction of secondary alcohols was developed for the synthesis of gamma-disubstituted alcohols and beta-disubstituted ketones. The protocol, using Mn-MACHO(Ph) as the catalyst, exhibited a wide substrate scope and good functional group tolerance, resulting in diverse valuable disubstituted alcohols and ketones in moderate to good yields. The selective formation of alcohol products was found to be influenced by reaction temperature, with alcohols favored over ketones at lower temperatures.

Summary: Here, we report a manganese-catalyzed three-component coupling reaction for the synthesis of beta,beta-methylated/alkylated secondary alcohols. Our method efficiently constructs assembled alcohols with high chemoselectivity in moderate to good yields using a series of 1-arylethanol, benzyl alcohol derivatives, and methanol. Mechanistic studies suggest that the reaction proceeds via methylation of a benzylated secondary alcohol intermediate to generate the final product.

Summary: We present a precise measurement of the asymptotic normalization coefficient (ANC) for the O-16 ground state (GS), which has a strong effect on the C-12(alpha, gamma)O-16 reaction rate. Based on the new ANC, the astrophysical S-factor and stellar rate of the reaction are determined, leading to an increase in the total reaction rate within the temperature range of astrophysical relevance. The updated reaction rate also impacts the pair-instability mass gap for black holes.

Summary: This study investigated the exposure levels and profiles of PCBs in pregnant women and newborns in Hangzhou and Mianyang, China. The results showed that the PCBs levels in the participants were lower than those in developed countries and were mainly influenced by environmental burden and dietary intake. Maternal exposure to PCB-126 was associated with increased birth weight, and certain health risks were identified. The study also found that the transplacental transfer of PCBs was influenced by log10 KOW.

Summary: The spatial variation and temporal trends of PFASs in agricultural soils of Eastern China from 2011 to 2021 were evaluated. PFOS concentration decreased by 28.2% during this period, indicating the effectiveness of the Stockholm Convention and voluntary phaseout in controlling PFOS pollution. Legacy PFASs were the major components, accounting for 63.8% of total PFASs, and the contribution ratio of consumer product industries steadily increased while that of fluoropolymer industries declined.

Summary: Anomaly detection in fundus images is challenging due to the diverse types of lesions and their properties. Current methods reconstruct or separate the fundus image background, but ignore the constraint from lesions and struggle with distinguishing lesions from backgrounds with normal personalized variations. To address these challenges, we propose a patch-based non-i.i.d. mixture of Gaussian model to adapt to diverse lesions and introduce a weighted Schatten p-norm for enhancing background learning. By modeling diverse lesions and learning background and personalized variations, our method outperforms state-of-the-art methods.

Summary: This study investigated the contamination levels and temporal variation of PBDEs and NBFRs in agricultural soils in China. The concentrations did not vary significantly over the past decade for PBDEs, but lower-brominated congeners increased with time. The concentrations of NBFRs also increased over time, with higher concentrations in 2021, 2016, and 2013 compared to 2011. The health risks of PBDEs and NBFRs were found to be low, but long-term health risks of BFRs should be considered.

Summary: In this study, the deoxygenation of secondary and tertiary amides using [Mn(CO)5Br] with Ph2SiH2 or inexpensive PMHS as reducing agents was reported, providing a convenient method for the synthesis of corresponding secondary and tertiary amines. The transformation is operationally simple, proceeds under mild conditions without external ligands, and exhibits high catalytic efficacy and good functional-group tolerance. Furthermore, the generality of this catalytic system was demonstrated by the late-stage modification of bioactive molecules.

Summary: This study investigated the effects of co-exposure to aged submicron particles (aSMPs) and Cd as model contaminants on rice leaves. The results showed that co-exposure reduced cadmium levels in leaves and significantly decreased cadmium accumulation. Exposure to Cd caused physiological, transcriptomic, and metabolomic changes in rice leaves, impacting crop yield and quality. Co-exposure with aSMPs affected the distribution of Cd in plants. Rice leaves co-exposed to Cd and aSMPs exhibited higher toxicity and Cd accumulation compared to those exposed solely to Cd. This suggests that the presence of aSMPs may lead to more pronounced gene expression regulation and changes in metabolic pathways. Our study found that co-exposure to Cd and aSMPs resulted in lower Cd accumulation and toxicity in rice leaves, potentially due to the capture of Cd by aSMPs, reducing its exposure and jointly inhibiting Cd-induced damage.
