Atmospheric deposition is an important source of trace metals to surface environments, but knowledge about plant bioavailability of recently deposited metals and their fate in the soil-plant system is limited.

Atmospheric Nitrogen Deposition
Science, 1997David A. Wedin and David Tilman (Reports, 6 Dec., p 1720 ) show that increased nitrogen inputs to terrestrial ecosystems might cause smaller increases in the capacity of those ecosystems to store carbon than expected.

The35S content in atmospheric deposition, aerosol and rain water was determined about every 10 days for a year with7Be,32P and some stable elements. Average35S concentrations were 110 mBq·m−2·d−1 for atmospheric deposition, 0.078 mBq·m−3 for aerosol in surface air and 45 mBq·l−1 for rain water.

Atmospheric Deposition and Forest Decline
Water, Air, & Soil Pollution, 1986This paper discusses the economic implications of alternative scientific explanations of observed forest decline. The various explanations can be grouped into two categories. One category posits direct damage to the forest canopy that is reversible. The other category posits indirect damage via soil quality changes that may be irreversible or slow to ...

Fungal community structure and function shifts with atmospheric nitrogen deposition
Global Change Biology, 2020Fungal decomposition of soil organic matter depends on soil nitrogen (N) availability. This ecosystem process is being jeopardized by changes in N inputs that have resulted from a tripling of atmospheric N deposition in the last century.

Atmospheric deposition sampler intercomparison
Water, Air, and Soil Pollution, 1988Two wet/dry atmospheric deposition sampler types were compared for 1 yr. The resistance required to open each of ten collectors was determined. Additionally, the opening and closing history of each sampler was recorded using a microdatalogger with a resolution of 1 min.

Atmospheric Deposition to Forest Ecosystems
2013Abstract Atmospheric deposition is an important source of macro- and micronutrients to the forest and also the most important channel for input of long-range air pollutants. This chapter describes the methods used for the determination of atmospheric deposition, especially in rain and snow, in forest ecosystems, including samplers for open-field bulk

Lake Ontario atmospheric deposition 1969–1978
Water, Air, and Soil Pollution, 1982Nine years of atmospheric deposition data have been analyzed from six locations along the Canadian shore of Lake Ontario. Results indicate that atmospheric deposition is affected by large scale air masses which influence the entire northern shore, and local inputs which at times could mask the large scale air masses effects.
