Global assessment of nitrogen deposition effects on terrestrial plant diversity : a synthesis [PDF]

, 2009
Atmospheric nitrogen (N) deposition is it recognized threat to plant diversity ill temperate and northern parts of Europe and North America. This paper assesses evidence from field experiments for N deposition effects and thresholds for terrestrial plant

New Insights Into Multi‐Component Atmospheric Wet Deposition Across China: A Multidimensional Analysis

Earth's Future, 2022
Atmospheric wet deposition has attracted much attention because of its removal function of aerosol particles and impact on ecosystem. It is a complex multi‐component process due to various pollutants emission sources and reaction processes.

History of nutrient inputs to the northeastern United States, 1930–2000 [PDF]

, 2013
Humans have dramatically altered nutrient cycles at local to global scales. We examined changes in anthropogenic nutrient inputs to the northeastern United States (NE) from 1930 to 2000.

Superposition Effects of Zinc Smelting Atmospheric Deposition on Soil Heavy Metal Pollution Under Geochemical Anomaly

Frontiers in Environmental Science, 2022
Guizhou Province is covered by a large area of carbonate rocks where, with a higher background of heavy metals under the geochemical anomaly, more than 3.6 × 105 ha of heavy metal–contaminated soil in the northwest area is related to historical ...

Global deposition of total reactive nitrogen oxides from 1996 to 2014 constrained with satellite observations of NO2 columns [PDF]

, 2017
Reactive nitrogen oxides (NOy) are a major constituent of the nitrogen deposited from the atmosphere, but observational constraints on their deposition are limited by poor or nonexistent measurement coverage in many parts of the world.

Comparison of mercury in atmospheric deposition and in Illinois and USA soils [PDF]

Hydrology and Earth System Sciences, 2004
It has been reported that most mercury (Hg) in USA soils is from atmospheric Hg deposition, mostly from anthropogenic sources. This paper compares the rates of atmospheric Hg deposition to amounts of Hg in Illinois and USA soils. The amounts of Hg in

Ecosystem recharge by volcanic dust drives broad-scale variation in bird abundance [PDF]

, 2015
Across the globe, deserts and volcanic eruptions produce large volumes of atmospheric dust, and the amount of dust is predicted to increase with global warming.
