Little is known about uranium, U(VI), transport in alkaline and saline solutions. However understanding U(VI) mobility in these conditions is critical due to the storage of U(VI) at high pH and ionic strengths (I). To this end we have studied the geochemical processes taking place in a reservoir, and during transport through quartz sand packed columns. The results show that at pH 10.5 and 11.5 ...

Fifty-eight terrestrial and salt-tolerant myxobacteria were isolated from the saline-alkaline soils collected from Xinjiang, China. Based on the morphologies and the 16S rRNA gene sequences, these isolates were assigned into 6 genera, Myxococcus, Cystobacter, Corallococcus, Sorangium, Nannocystis and Polyangium. All the strains grew better with 1% NaCl than without NaCl. Some Myxococcus strains...

the acute toxicity of salts of alkali and alkaline earth metals, such as sodium (na), potassium (k), calcium (ca) and magnesium (mg) were studied on the egg and larval stages of indian major carp labeo rohita (hamilton). the acute toxicity experiments were conducted followed by the range finding bioassay tests. the experiments were conducted in triplicates. the cumulative percentage of dead or ...

Lake Magadi is an internally drained, saline and alkaline terminal sump in the southern Kenya Rift. Geochemistry of samples from ~200 m core representing past ~1 m.y. lake’s history shows some highest concentrations transition metals metalloids ever reported lacustrine sediment, including redox-sensitive elements molybdenum, arsenic, vanadium. Elevated these represent times when hypolimnion was...

Abstract There is evidence of increased soil organic carbon (SOC) and inorganic (SIC) under fertilization in dry croplands arid semi-arid areas. However, not much known about the responses SOC SIC coastal saline − alkaline paddy soils that undergo flooding draining cycles. Here, we assess impacts various combinations phosphorus on other properties a field Yellow River Delta. Our study showed re...

In the context of deep waste disposals, geological barrier (i.e., host rock) will be exposed to saline plumes from bituminous and alkaline concrete degradation. These chemical disturbances affect hydraulic mechanical properties clay rock by modifying its microstructure. As a result, self-sealing fractures created during excavation could affected,further affecting long-term safety repositories. ...
