Rainwater chemistry

Marine Primary Productivity as a Potential Indirect Source of Selenium and Other Trace Elements in Atmospheric Deposition, Tim Blazina, Alexander Läderach, Gerrad D. Jones, Harald Sodemann, Heini Wernli, James W. Kirchner, and Lenny H. E. Winkel, Environ. Sci. Technol., 2017, 51 (1), pp 108–118.

Chemical cycling through the air, water and soil is an important theme without our text, demonstrating the various way chemicals move and are transformed in the environment. We show many of such cycles, including water, phosphorus, calcium, copper, mercury, sulfur and nitrogen. This paper discuss the important role atmospheric processes play in the movement of Se and other trace elements (vanadium, cobalt, nickel, and zinc, and also include aluminum) to the terrestrial regions through precipitation.

Chemical composition of rainwater at a coastal town on the southwest of Europe: What changes in 20 years?, Santos P. S. M., M. Otero, E. B.H. Santos, A. C. Duarte, Science of the Total Environment 409 (2011) 3548–3553 (Published by Elsevier, May 2011).

In Section 5.1 on page 104, we provide examples of chemical composition of rain, as does this article, but in a different geographical area and with 20 years of time between samples. This paper provides clear evidence that anthropogenic effects are continuing to alter precipitation composition.
