A.P. Aizebeokhai ( ) Department of Physics, College of Science and Technology, Covenant University, Ota, Ogun State, Nigeria e-mail: [email protected] Abstract The presence of contaminants in the environment requires a precise characterization of the nature and extent of contamination for effective remediation. Conventional environmental monitoring has focused largely on point s...

Landfilling is the most commonly used method for solid waste disposal in Jordan. It is an important source of pollution, which can be displayed through analysis of data for climatic conditions, hydrology and geology of the country. The migration of gas and leachate from the landfill body into the surrounding environment present a serious environmental concern, which include groundwater pollutio...

The oxidation of iron sulfides in mine wastes is the main cause of acidic, sulfate, and trace element-rich acid mine drainage (AMD). However, the suite of reactions that transform iron from one species to another is quite complex. A reasonable strategy for controlling AMD production is to identify and further slow the slowest, rate-determining step (RDS) in the overall process. This paper provi...

Introduction In reviewing and assessing the importance and role of laboratory exercises in earth sciences, we begin with defining the scope of this review. The ensuing discussion is limited to fields of study that have traditionally formed the core of studies of the solid earth, specifically geology, soil science, and geomatics (remote sensing and geographic information systems). Related subjec...

BACKGROUND The field of medical geology addresses the relationships between exposure to specific geological characteristics and the development of a range of health problems: for example, long-term exposure to arsenic in drinking water can result in the development of skin conditions and cancers. While these relationships are well characterised for some examples, in others there is a lack of un...

Boundaries on the new map of the Natural Vegetation of Ohio by Gordon (1966) neatly follow, in most places, geologic boundaries. Where this is not true, conditions controlling this distribution are either aspect, microclimate, or the result of some as-yet unrecognized variation in the geology. Vegetation-geology correlations may be generalized as follows. Beech (-maple) forests occur on better ...

Aim The aim of this study was to document changes in forest composition, structure and distribution across Massachusetts, USA, from the time of European settlement (seventeenth century) to the present, and to investigate environmental and historical influences on regional patterns of variation. Location The study area encompasses the State of Massachusetts (69.9–73.5 E, 41.3– 42.9 N), a 21,000-...
