Progress in Medical Geology
This volume represents a compendium of research conducted by international scholars who participated in the 2nd Symposium on Advances in Geospatial held during “The 5th International Conference on Medical Geology” in Arlington, Virginia, USA, in 2013. The research topics dealt with here mainly focus on the new scientific field of medical geology used to address a variety of human health issues and diseases specifically related to geological materials and earth-system processes. This volume will be of interest to those who wish to learn about current and historical health issues relating to geological materials or other environmental factors. It also represents a useful guide to learning the interdisciplinary approach to problem-solving in the field of medical geology.
Hydrogeochemistry of the Pidong Crater Lake, Jos Plateau Volcanic Province, Nigeria
The occurrence and recurrence of floating ,Äòmat,Äô vegetation around the Pidong Crater Lake and intermittent change in the color of the lake water from natural blue to brown-yellowish color call for a better understanding of the factors controlling these biological and physico-chemical changes. As a result of these changes, a hydrogeochemical monitoring regime was employed where the lake water samples were collected and analyzed on a monthly basis over a period spanning for 3¬†years. The hydrogeochemical results for the lake water when plotted in the piper trilinear diagram display predominantly Mg-Ca-HCO3 type with minor water types of Na-K-HCO3, Na-K-Cl and Na-K-SO4 types (,⧠20%), suggesting a derivation from water-rock interaction processes (hydrolysis). The visible dominance of the alkali earth metals (Mg2+ + Ca2+) over the alkali metals (Na+ + K+) is expected from a basaltic host rock aquifer due to the dissolution of its constituent ferromagnesian minerals and plagioclase respectively. The general depletion of LILE (Ba, Rb, Sr) (1,Äì10 x Chondrite) and that of High Strength Elements (HSE) (Nb-Yb) (0.001 to
Progress in Volcanology
Progress in Volcanology includes nine chapters in three sections. The first section is the “Introduction” while the other two sections speak on “Applied Volcanology” and “Volcanic Sedimentology, Geochemistry and Petrology.” The chapters address volcanology in several areas around the world, including Italy, Indonesia, Ethiopia, Argentina, India, and others.
Calcium and Magnesium in Groundwater
Calcium and magnesium are abundant in groundwater, but the role of groundwater as the essential source of these important nutrients is very often neglected. Hydrogeochemical studies have focused mainly on the distribution and behaviour of constituents that cause deterioration of water quality, such as: nitrate, nitrite or iron and manganese. Therefore, most recent books and papers concentrate mainly on these constituents and only a small number of papers describe the results of groundwater studies on other important water components such as calcium or magnesium. Calcium and magnesium are of great importance to human wellbeing and inadequate intake of either nutrient can impair health. The ma...
