Under the Egyptian program for radiation safety and control, airborne radioactivity measurements and radiological dose assessment were conducted in some phosphate and uranium mines. Abu-Tartor mine is one of the biggest underground phosphate mines in Egypt. Airborne radioactivity, radon ((222)Rn) and its short-lived decay products (progenies) and thoron ((220)Rn), were measured in selected loca...

We report the draft genome sequence of arsenite-oxidizing Halomonas sp. strain HAL1, isolated from the soil of a gold mine. Genes encoding proteins involved in arsenic resistance and transformation, phosphate utilization and uptake, and betaine biosynthesis were identified. Their identification might help in understanding how arsenic and phosphate metabolism are intertwined.

Phosphate-induced immobilization is recognized as one of effective in situ remediation methods for heavy metal contaminated soils. Phosphate-based minerals that adsorb, chelate, or complex heavy metals in soil were greatly concerned as effective heavy metals immobilizing materials. Effects of particle sizes of rock phosphate on immobilizing heavy metals in Pb-Zn mine soils by a greenhouse exper...

Phosphorus solubilizing microorganisms are capable of transforming insoluble phosphorus (P) forms to soluble and bioavailable P. The aim of the present study was to isolate P solubilizing bacteria from forest soils around the rock phosphate (RP) mine of Koh-e-SepidLar in Kohgiluyeh and Boyer Ahmad province and evaluate their ability in Sperber culture medium and wheat straw medium in the presen...

dissolution of phosphate by p solubilizing microorganisms is dependent on the environmental conditions and the composition of the medium culture. present study conducted to investigate the effect of two fungal species, moisture content and rock phosphate content on water soluble phosphate (wsp), ph and changes of medium weight with time. two fungi aspergillus niger and one isolate from rock pho...
