Abstract
Um Bogma area is the most famous mineralized locality in Sinai, Egypt. It is characterized by the presence of manganese, iron, and copper deposits. Apart from the mill tailings and spoil heaps, the results indicated the decrease of soil contamination downstream. As a result of random manganese mining activity in Um Bogma area, many hazardous elements such as iron, copper, manganese, lead, and zinc as well as many others associating heavy metals such as arsenic, selenium, and sulfur are dispersed in the environment. This study assesses and monitors the environmental impacts of such mining activities in the west central Sinai, using multitemporal spectral remote-sensing sensors (MSS 1972, TM 1986, and ETM+7 2000). The results have shown the very high potential of temporal imagery in mining-related contamination either directly through mineral and rock mapping of the mining waste and residues and related contaminated areas.
