Summary: The development of trade has caused significant pollution problems, and the impact of trade policies on firms' pollution has gained attention. By examining the exogenous shock of the export tax rebate (ETR) policy changes on highly energy, highly polluting and resource consuming (HHR) products, this study finds that the ETR reform reduces the SO2 emission intensity of Chinese industrial firms by promoting investment in environmental protection equipment and improving energy utilization. Furthermore, the policy has a more pronounced effect on technology-intensive firms, firms with cleaner export product structures, and firms located in areas with weaker environmental protection forces. This paper provides empirical evidence supporting the governance of corporate pollution through ETR policy.

Summary: In this study, dust aerosols were generated in the laboratory using soils with various physicochemical properties, and the concentrations of PAHs in the soils and generated dust aerosol were measured. The enrichment factors (EFs) of PAHs were found to be influenced by soil texture, PAH contamination level, molecular weight of PAH species, and aerosol sizes. PAHs with higher EFs usually had higher molecular weights. Furthermore, there was a positive correlation between EFs of PAHs in different particle sizes and the total organic carbon content of dust aerosol.

Summary: Through experiments, it was found that perfluorobutanesulfonic acid (PFBA), perfluorooctanoic acid (PFOA), and perfluorononanoic acid (PFNA) with different carbon chain lengths significantly reduced the antibacterial ability of zebrafish during the early-life stage, suppressed the innate and adaptive immune systems, and showed a positive correlation with carbon chain length. It was also discovered that PFASs exerted immunomodulatory effects by activating downstream genes of the Toll-like receptor, and inhibiting the Toll-like receptor pathway could alleviate the immunotoxicity of PFASs.

Summary: This study aims to rapidly evaluate the fatigue life of butt joints Q310NQL2-Q345NQR2 using the concept of energy dissipation within the framework of thermodynamics. A Representative Volume Element (RVE) model is introduced to characterize the energy dissipation related to two microstructural movements, i.e., anelastic and inelastic dissipated energy. The inelastic energy dissipation is used to deduce a non-linear damage evolution model, and a normalized damage model is developed based on this. S-N curves with different probabilities are estimated using the maximum likelihood method, and they are validated by test data.

Summary: This study proposes an improved density peaks clustering algorithm based on scenario construction to address the severity ranking problem of railway accidents. Firstly, a five-dimensional railway accident scenario expression model is introduced, which dynamically selects and expresses grading indicators. Secondly, an improved density peaks clustering algorithm based on k nearest neighbors and turning point (IDPC-KNN-TP) is established as the grading model, optimizing the local density measurement, cluster center point selection, and density peaks clustering assignment strategy. The algorithm demonstrated better performance and practicality in the analysis of UK railway accidents from 2010 to 2021. The study provides a dynamic grading strategy and emergency disposal suggestions, offering a reference for hierarchical response to railway accidents.

Summary: Dust aerosols are produced by wind erosion, and the production is influenced by the wind speed and soil moisture content. The relative humidity (RH) indirectly affects dust production by influencing soil moisture content. This study shows that RH has a direct and complicated impact on dust aerosol production, mainly due to its effects on electrostatic and wet-bonding forces between soil particles. The current formula for estimating dust production does not consider the direct effect of RH, which can lead to significant errors.
