Volcanic Activity: Some Effects of the Emissions on the Acidification of the Environment

Abstract

The Japanese Islands is one of the most volcanic regions in the world. Since it has been estimated that about one half of sulfur dioxide in Japan is emitted from volcanoes, more precise survey of the volcanic emissions should be made.
This paper is concerned with the contribution of volcanoes to the atmospheric sulfur budget and the role of volcanoes on the quality of air and precipitation. It also covers the progress made so far in the related studies on the long-range transport of sulfur in East Asia and discusses the task that lie ahead.
