An Approach to Problems of a Geothermal Mercury Survey, Puna, Hawaii
Journal Article: An Approach to Problems of a Geothermal Mercury Survey, Puna, Hawaii
AbstractConcentrations of soil mercury of 15 to 1250ppb were determined in the Puna geothermal areaon the lower east rift zone of Kilauea volcano. As the area is young and volcanically active a wide range of soils exist. Hg concentrations are partly controlled by such factors as soil development and organic content, which tend to complicate interpretation of the absolute concentrations measured. The pH of both ground gas and soil may also influence transport and fixation of the Hg, and some low pH soils may be due to SO2 and C02 in ground gas. By relating the Hg concentration of the samples to the background concentration for different soil types these influences can be significantly reduced, producing results that better reflect the geothermal component of Hg to the soil. The major difficulty in using this approach in an area with marked variations in soil type is in determining the background concentrations and in the classification of the soil types.
