Strontium is considered to have moderate or moderatetolow mobility in soils. The primary target of strontium exposure is the bone. The chemical similarity of strontium to calcium allows it to exchange imperfectly for calcium in a variety of biological processes; the most important of this is the substitution of calcium in bone, affecting skeletal development.

Abstract. At nuclear contaminated sites, microbiallymediated Fe(III) reduction under alkaline conditions opens up the potential for cotreatment of the groundwater contaminants Tc99, though reduction to less mobile Tc(IV) phases, and Sr90, through increased sorption and/or precipitation promoted at higher pH.

Jan 04, 2011· The ratio of strontium87 to strontium86 (87 Sr/ 86 Sr) is used extensively as a natural tracer in groundwater to detect mixing among waters from different sources and to study the effects of water/rock interaction. On a plot of the reciprocal strontium concentration against the 87 Sr/ 86 Sr ratio, mixtures of two end members will produce a linear array.

Apr 26, 2013· Bioremediation of environmental niches such as soil, sediments and water contaminated with radionuclides can be achieved through biologically encoded changes in the oxidation state. Changes in speciation such as detoxification of mercury by methylation [Hg(CH 3 ) 2 ] can alter the solubility, transport properties and toxicity of radionuclides (Wang et al ., 2012 ).

Enhancing the ability of groundwater to recover from quality degradation What is it about? Near Berlin, contaminated groundwater was entering a borehole field in one of the city's main water supply schemes, which provides about 30,000 m3 of water per day for about 300,000 people. The main contaminant was. Continue reading

Bioremediation. Bioremediation means to use a biological remedy to abate or clean up contamination. This makes it different from remedies where contaminated soil or water is removed for chemical treatment or decontamination, incineration, or burial in a landfill.

Bioremediation20Exposure to this radiation can cause radiation burns and cancer. In addition, strontium (Sr) can replace calcium in bones and become concentrated enough to cause radiation injury from within the body. The problem with containment sites of these radioactive materials is that they can leak. Most of the leaking is

Genes for the central enzymes of anaerobic monoaromatic compound degradation have also been employed to monitor degraders in the field. Hence, a substantial diversity of class I benzoylCoA reductase (bcrA) genes was first reported for a gasolinecontaminated aquifer in Kumamoto, Japan (Hosoda et ). Distinct gene pools were found in different wells and degrader abundance .
