Air Concentration and Deposition Rates from Uniform Area sources - A Technical Report

The surface of the earth or the sea may release certain substances to the atmosphere. Often these substances are also classed as pollutants when produced by human activities. This report provides a theory and illustrative charts to predict the natural contribution to the air concentration or deposition. To apply the theory, the natural source strength must be known and, unfortunately, this is often unavailable. The theory has been approximately validated by several natural substances such as radon gas and lead.
