The relative-rate technique has been used to obtain the rate coefficients for the reactions of the saturated aldehydes (SA): Octanal (OCT) CH3(CH2)6C(O)H and Nonanal (NON) CH3(CH2)7C(O)H with OH radicals and Cl atoms at ...

Abstract Background Polycyclic aromatic hydrocarbons (PAHs) comprise a group of persistent carcinogenic pollutants whose transfer from air to soil via the atmospheric deposition represents a major chronic exposure pathwa...

Small unmanned aerial systems (sUAS) are increasingly being used to conduct atmospheric research. Because of the dynamic nature and inhomogeneity of the atmospheric boundary layer (ABL), the ability of instrumented sUAS ...

Mining activities in the Kenyan Marble Quarries (KMQ) are a potential source of atmospheric pollution, raising health concerns for the local population. This study aims to examine the extent to which marble mining contri...

This article presents a statistical analysis of the relationship between the development of the circular economy and climate change in Ukraine during the period 2010–2024. The circular economy, as an alternative model ...

Abstract Key roles of marine dimethyl sulfoniopropionate (DMSP), dimethyl sulfide (DMS), methyl mercaptan (MeSH), and carbon disulfide (CS2) in the sulfur cycle and/or atmospheric chemistry, alongside the rapid environme...

Poly- and perfluoroalkyl substances (PFASs) are persistent environmental pollutants widely used in industrial applications due to their thermal stability and chemical resistance. However, their persistence in the environ...

The primary study objective is to verify the environmental Kuznets curve hypothesis for greenhouse gas emissions in Poland at the disaggregated Nomenclature of Territorial Units for Statistics (NUTS)-3 level, accounting ...

BackgroundMeteorological factors are among the key extrinsic triggers for the onset and exacerbation of cardiovascular and cerebrovascular diseases (CVD). Against the backdrop of sustained global warming, elucidating the...

Amid rapid urbanization, China faces dual challenges of air pollution (AP) and carbon emissions (CE), urgently requiring synergistic governance—an area that remains underexplored due to limited dynamic and heterogeneou...

The Federal Aviation Administration (FAA) has put forth a set of regulations (Part 107) that govern small unmanned aerial system (sUAS) operations. These regulations restrict unmanned aircraft (UA) from flying over peopl...

Abstract Rising atmospheric carbon dioxide is projected to exceed 800 ppm by 2100, yet its impact on acid mine drainage (AMD), which is currently contaminating 480,000 km of rivers, remains unclear. Here we combine a g...

Abstract Lava tubes formed during the 2021 Tajogaite eruption on La Palma (Canary Islands, Spain) provide a rare opportunity to investigate the earliest stages of microbial colonization in a newly created subterranean vo...

This paper explores the many aspects of precipitation measurement that are relevant to providing an accurate global assessment of this important environmental parameter. Methods discussed include ground data, satellite e...

Abstract Atmospheric rivers cause extreme precipitation and sustain water resources in the western United States. Their occurrence has often been attributed to extratropical cyclones. Here, we apply a recently proposed m...

Abstract Egypt’s New Delta Project, one of the country’s largest land reclamation initiatives, aims to boost agricultural production, support population growth, and strengthen food and water security. However, large-...

The Southeastern United States (US) has experienced increased population growth and urbanization in recent decades, highlighting the importance of water management and availability. The Black Warrior River basin is in an...

Hydrocarbon pollution from oil spills, traffic emissions, and industrial processes continues to be a significant global threat to biodiversity, soil quality, water quality, and human health. Lichens, mutualistic life for...

Abstract Air pollution is a major environmental and public health challenge in Greater Cairo due to rapid urbanization, intense traffic activity, and recurrent regional dust intrusions. This study presents a data driven ...

Evidence of teratogenesis and mutagenesis documented in the palynological assemblages of the Middle Triassic Quebrada de los Fósiles Formation, San Rafael Depocenter (Mendoza, Argentina) provide an independent testimony...

Abstract Background Hospital indoor air is contaminated with multidrug-resistant bacteria, and this contributes to their spread. However, there is limited information linking environmental and atmospheric factors to the ...

Abstract Peroxyacetyl nitrate (PAN) is a key secondary pollutant formed through atmospheric photochemical reactions and is regarded as a characteristic indicator of photochemical pollution. In China, while primary pollut...

Abstract Background With the rapid advancement of industrialization and urbanization, air pollution is becoming increasingly serious, posing a huge threat to human health. There is ambiguity in the research on the impact...
