Introduction: Rock weathering is a fundamental process that shapes Earth's topography, soil formation, and other surface processes. However, the mechanisms underlying the influence of fertilizer application on weathering remain poorly understood, especially with respect to bacterial intervention.
Methods: In this study, purple parent rocks from Shaximiao Group (Js) and Penglaizhen Group (Jp) were selected to investigate the effects of fertilizer application on the bacterial community and weathering characteristics of these rock by leaching experiment.

Functional safety is an emerging trend for safety design in the automobile industry. This study is an innovative exploration of a hazard analysis and quantitative risk assessment (QRA) methodology based on the functional safety of vehicular fuel cell systems. In this study, the potential hazards that fuel cell vehicles may encounter during operation were identified using the automobile generic hazard list.

The distribution and transport of polycyclic aromatic hydrocarbons (PAHs) in urban environments are influenced by both anthropogenic sources and natural landscape features. While previous research has primarily focused on human activities as drivers of PAH pollution, the role of terrain-especially in cities with complex topographies-remains underexplored. To investigate the effect of terrain features on PAH distribution and transport, we analyzed topsoil samples evenly distributed in Chongqing, a city with hilly terrain (elevation: 48-2300 m).

Electronic address:
The accumulation and persistence of Bt toxins in soils from Bt plants and Bt biopesticides can result in ecological hazards. Earthworms are one of the most frequently used bioindicators for soil ecological monitoring, characterization, and risk assessment. However, the effects of Bt toxins on earthworm bacterial communities have conversely rarely been studied.
