Themed collection Environmental Science Atmospheres Recent Review Articles

A methane framework based on a set of taxonomies and a common lexicon that provides a common structure in which data requirements, emission sources and monitoring methods can be described.

Hydrogen may play a major role as an energy source to support net zero but combustion leads to emissions of NO_x, a key air pollutant. Delivering optimal air quality co-benefits may need more ambitious hydrogen-specific emission standards developing.

Atmospheric amines from various sources undergo a variety of homogeneous and heterogeneous reactions to contribute to the overall process of aerosol particle formation and further affect the climate.

Microplastics (MPs) are emerging contaminants that require attention in sampling, analysis, and characterization in both indoor and outdoor air pollution to mitigate the potential dangers they pose to public health and the economy.

Harmful algal bloom events are increasing; aerosol particles from sea and lake sprays carry algal bloom toxins that react with atmospheric oxidants, creating transformation byproducts. Inhaling these toxins with air pollutants may pose health risks.

Carbon monoxide is a priority pollutant that is suitable as an indicator for assessing indoor air quality. Monitoring should preferably be embedded in an intelligent network of different sensors.

Different processes can lead to high electrical field strengths in snow and ice in polar regions with the potential to initiate free radical processes and a number of other chemical modifications.

This article reviews scientific evidence for the potential environmental impacts of stratospheric aerosol injection, a form of solar radiation geoengineering.

The effects of aviation's non-CO₂ emissions on climate and air quality are complex and relatively poorly understood. Mitigation measures need to be very carefully considered so that perverse outcomes do not result.

Although prediction methods exist for the partitioning between air and various environmental and biological phases, that do not depend on octanol, the K_OA still serves a role as a single parameter quantifying compound volatility from different phases.

Marine aerosol feedback on biogeochemical cycles and the climate remains highly uncertain due to the complex interplay. This review highlights recent advances in our understanding of organic aerosols, nitrogen, and iron as well as cloud properties over the Pacific Ocean.

Much of the ozone that enters buildings reacts with human skin oils, both on occupants and on other surfaces. Products of these reactions influence human chemical exposures.

Acetaldehyde is ubiquitous in the atmosphere. The relevant sources and the concentrations occurring indoors are discussed and evaluated on the basis of health-related criteria and guide values.

The high toxicity of isocyanate species in the workplace demands the development of sensitive techniques for the detection of isocyanates to protect workers from adverse health effects.

Microplastics (MPs) in the atmosphere are ubiquitous and persistent emerging pollutants which have been an environmental issue of global concern.

During the last several decades, numerous researchers have provided evidence that physical and biogeochemical processes at air-snow/ice-water interfaces are very complex, and, in many cases, interlinked.

Hydrogen–diesel co-fuelling may reduce NO_x and PM_2.5 emissions if used in lower load construction machinery and HGVs. In high load applications such as electrical generators, emissions could be higher than pure diesel, unless further abated.

Being a climate change nexus, the study on the carbon cycle depicts the existence of its mechanistic link with the atmospheric and biospheric environment.

We report on key findings and knowledge gaps identified regarding measurement and modelling techniques used to quantify deposition of N_r across complex terrain in the UK, which may represent up to 60% of land coverage across Great Britain.

Surfactants alter the physical and chemical properties of atmospheric aerosol particles.

Crop types have significant impacts (p < 0.05) on the background nitrous oxide emissions (BNE) from soils. The annual BNE for China when considering the proportion of planting area is 0.69 ± 1.52 kg N–N₂O ha⁻¹.

Particulate nitrate photolysis can lead to the formation of secondary inorganic and organic aerosols that affect climate, air quality, and human health.

Satellites could revolutionise the way global oil and gas methane is reported. There are many barriers to overcome before satellites can play an active role in methane emissions reporting.

Iron in mineral dust can catalyze reactions with atmospheric organics that lead to the formation of brown carbon (BrC) that impact the climate in a number of ways.
