Atmospheric nitrogen deposition: A review of quantification methods and its spatial pattern derived from the global monitoring networks

open access: yesEcotoxicology and Environmental Safety, 2021
Atmospheric nitrogen (N) deposition is a vital component of the global N cycle. Excessive N deposition on the Earth’s surface has adverse impacts on ecosystems and humans.

Marine and terrestrial contributions to atmospheric deposition fluxes of methylated arsenic species [PDF]

open access: yesNature Communications
Arsenic, a toxic element from both anthropogenic and natural sources, reaches surface environments through atmospheric cycling and dry and wet deposition. Biomethylation volatilizes arsenic into the atmosphere and deposition cycles it back to the surface,

Modeling and mapping of atmospheric mercury deposition in adirondack park, new york. [PDF]

open access: yesPLoS ONE, 2013
The Adirondacks of New York State, USA is a region that is sensitive to atmospheric mercury (Hg) deposition. In this study, we estimated atmospheric Hg deposition to the Adirondacks using a new scheme that combined numerical modeling and limited ...

Do contemporary (1980–2015) emissions determine the elemental carbon deposition trend at Holtedahlfonna glacier, Svalbard? [PDF]

open access: yesAtmospheric Chemistry and Physics, 2017
The climate impact of black carbon (BC) is notably amplified in the Arctic by its deposition, which causes albedo decrease and subsequent earlier snow and ice spring melt.

Sampling of Atmospheric Precipitation and Deposits for Analysis of Atmospheric Pollution [PDF]

open access: yesJournal of Analytical Methods in Chemistry, 2006
This paper reviews techniques and equipment for collecting precipitation samples from the atmosphere (fog and cloud water) and from atmospheric deposits (dew, hoarfrost, and rime) that are suitable for the evaluation of atmospheric pollution. It discusses the storage and preparation of samples for analysis and also presents bibliographic information on

A nationwide monitoring of atmospheric microplastic deposition [PDF]

open access: yesScience of The Total Environment, 2023
Plastic production continues to increase every year, yet it is widely acknowledged that a significant portion of this material ends up in ecosystems as microplastics (MPs). Among all the environmental compartments affected by MPs, the atmosphere remains the least well-known.

Quantitative source apportionment of heavy metals in atmospheric deposition of a typical heavily polluted city in Northern China: Comparison of PMF and UNMIX

open access: yesFrontiers in Environmental Science, 2022
Receptor models are rarely utilized in atmospheric deposition but are often used to identify pollutant sources and quantify their contributions. This article focuses on the soil in atmospheric deposition in a typical polluted city. Atmospheric deposition
