Discovery of new geophagic clayey deposit in the locality of Meka'a contributed to the apparition of new species of geophagic clay materials in the local market. Due to the fact that positive or negative effects of geophagia are conditioned by physico-chemical, mineralogical and geochemical properties of the clay soil ingested, it is therefore necessary to mineralogically and physico ...

Abstract. This work investigates the correlations existing among soil organic carbon (C), nitrogen (N), phosphorous (P), potassium (K), and physicochemical properties like clay mineralogy, textural components, soil aggregation, and land use pattern.

were inferred from their Atterberg limits and amount of clay-sized fractions (Diko et al., 2012). According to Fall and Sarr (2007), and Mugagga et al. (2011), by comparing soil PI and amount of clay-sized fraction (< 2 μm) present, the activity or expansivity of the soil can be quantitatively

Geophagia is widespread in the animal kingdom. Galen, the Greek philosopher and physician, was the first to record the use of clay by sick or injured animals in the second century AD.This type of geophagia has been documented in "many species of mammals, birds, reptiles, butterflies and isopods, especially among herbivores".

AbstractNine geophagic material samples were analysed in order to characterise their mineralogical and elemental constituents, and infer on their health threats. Most abundant mineral in the samples was quartz, followed by smectite, kaolinite and muscovite in minor; and microcline, plagioclase, and goethite in trace quantities. Dominant major oxides were SiO2 (43 - 74 wt%) and Al2O3(15 - 19 wt%).

Over 750 million people around the world lack access to potable water, and are thus faced with several water-related health challenges (WHO/UNICEF 2014).Surface water sources are usually polluted with dissolved solids, minerals, heavy metals, toxic anions, organic and inorganic substances which have unfavourable effects on flora and fauna (Awuah et al. 2009).

Abstract. The present study was carried out to evaluate the impact of the effluents and the solid wastes generated by a giant pulp and paper mill in the northeastern part of India on soil mineralogy of the area.

A graphite monochromator with a PW 1877 Automated Power Diffraction, X'PERT Data Collector soft-ware package was employed for qualitative identification of the minerals (Diko and Ekosse, 2012 Diko, M.L. & Ekosse, G.E. 2012.

Geophagia – the deliberate consumption of soil – has been practised for many centuries by a range of ethnic, religious and social groups in the world for a number of reasons. They include, but are not exclusive to, the following: nutrient supplementation; detoxification; alleviation of ...
