Themed collection Atmosphere – Biosphere Interactions – Topic Highlight

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.

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.

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

Little is known about the chemical composition of bioaerosols (pollen, fungi, algae, bacteria). In this study, several bioaerosols were characterized for their functional groups with ¹H-NMR and were quantitatively analyzed for individual organics.

Investigates the synergistic impacts of particulate matter and nanoplastics on the vitality and longevity of Artemia salina, emphasizing the potential implications for environmental sustainability and ecological balance.

Increased temperatures coupled with reduced light availability due to increased cloudiness can alter the ecosystem–atmosphere exchange of trace gases in the northern high-latitude regions with important climate feedback implications.

Measurements of biomass burning organic aerosols using the capture vaporizer-ACSM are interfered with by sea salt aerosols, as both have m/z 60 as a marker ion and the capture vaporizer is able to detect refractory particles like sea salt.

Urbanization-influenced airborne microorganisms and megacity bioaerosols have garnered particular attention due to their importance in the atmospheric environment.

Reduced-form modeling approaches are an increasingly popular way to rapidly estimate air quality and human health impacts related to changes in air pollutant emissions.

Far-UVC irradiation (222 nm) is an emerging approach for disinfection due to its effectiveness and potentially harmless nature to humans by direct irradiation compared with other UV wavelengths.

A multiphase kinetic model analysis quantifies effects of air pollutants on reactive oxygen species production and oxidative stress in the respiratory tract.

Sesquiterpene composition at two sites representative of the southeastern U.S. is similar with β-caryophyllene and humulene dominating ozone reactivity.

Bioaerosols within sea spray are particles of biological origin with various important atmospheric implications. These particles were characterized here using novel single-particle spectroscopy and microbial community composition analysis.

Drought stress was identified as the most important abiotic stressor that modulates emissions of biogenic volatile compounds in a Northern European city. Isoprene concentrations were reduced by 65% under drought stress during the growing period compared to non-stress conditions.

Lung surfactant at the air water interface reacts with ozone leading to changes in surface tension, film thickness, structure.

The Amazon rainforest is the largest source of isoprene emissions to the atmosphere globally.

Increased atmospheric Fe loading and solubility was attributed to emissions from Heard Island volcano (Kerguelen plateau), emphasizing the need for models to consider volcanoes as a source of aeolian Fe to remote oceanic regions.
