Atmospheric Deposition of Toxic Pollutants to the Great Lakes As Measured by the Integrated Atmospheric Deposition Network

Environmental Science & Technology, 1998
To determine atmospheric deposition of anthropogenic contaminants to the Great Lakes, the United States and Canada established the Integrated Atmospheric Deposition Network (IADN), designed to collect regional data representative of the air over the lakes.

Atmospheric Deposition and Forest Decline

Water, Air, & Soil Pollution, 1986
This 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 ...

Deposition of atmospheric ammonia to moorlands

Environmental Pollution, 1992
Micrometeorological methods were applied to measure fluxes of atmospheric ammonia (NH3) to moorlands. Measurements were made in a wide variety of surface conditions and included both Calluna vulgaris (L.) Hull and Eriophorum vaginatum L. dominated sites.

Deposition of atmospheric pollutants on forests

Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1989
Abstract Forests have long been considered as efficient sinks for atmospheric pollutants. The potential for large rates of deposition is provided by the turbulent structure of air above and within forest canopies. Large rates of deposition of pollutant gases, however, are only found for the very reactive gases HNO3, HCl and NH3.

Atmospheric deposition of35S

Journal of Radioanalytical and Nuclear Chemistry, 1999
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 to Forest Ecosystems

2013
Abstract 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
