Estonian phosphorite ore contains trace amounts of rare earth elements (REEs), many other d-metals, and some radioactive elements. Rare elements, Mo, V, etc. might be economically exploitable, while toxic should removed before any downstream processing for environmental nutritional safety reasons. All untreated hazardous remain in landfilled waste much higher concentration than they occur natur...
Radon 222 is a natural radioactive element with a half-life of 3.8 days. It is odorless and colorless as well as water-soluble. Consuming waters which contain high concentration of 222Rn would increase the effective dose received by different age groups. It would also be followed by an increased prevalence of cancer. In this research, 72 samples of the most commonly used bottled water in Bandar...
membrane assisted liquid extraction(male) technologies are gaining an important role as an extraction /separation technique for actinides and are being deployed as a promising tool for remediation of nuclear waste generated in the reprocessing plant and other radioactive wastes containing a trace level of radionuclides. the present contribution outlines the classification of membrane assisted ...
Lichens, a symbiosis of fungi and algae, have been widely used for biological monitoring of environmental quality. As some lichen species are virtually cosmopolitan organisms, they may be used for a survey of organic, inorganic, or radioactive contaminants on more or less a global scale, as well as for regional comparisons, and certainly at a more local scale. Some examples will be given for th...
The trace element content of clinkers (and possibly of cements) can be used for the qualitative identification (i.e. manufacturing factory). Several hundred clinker sorts have been analysed (by replicated quarterly samples, collected from all Hungarian cement factories as well as from factories of 8 foreign countries) to determine their Mg, Sr, Ba, Mn, Ti, Zr, Zn and V content. The first 6 elem...
Background and Aim: Diabetes is a metabolic disorder, in which either there is no sufficient insulin in the body or the available insulin is not capable of acting properly. Defining the effects of trace elements can help to make use of these elements in control or preventing diabetes. Materials and Methods: Forty-eight Wistar male rats were equally divided into eight groups. Three different ...
background: there are studies that indicated dyshomeostasis of oxidant/antioxidant and trace elements in breast cancer patients, but the data regarding the status of these parameters in various stages of breast cancer are limited. the aim of this study was to highlight the status of these biochemical factors in various stages of breast cancer. methods: fifty-eight breast cancers patients partic...
the present study was conducted to evaluate the effect of parenteral supplementation of cobalt, copper and iron in late pregnancy on ewe hematology parameters and lamb vigour. twenty ewes were allocated to one of two groups (n=10). in the test group, on day 120 ofpregnancy, cobalt, copper and iron were injected at a dose of 0.1 ml/kg bw (fercobsang, france, cobalt gluconate 5 mg/100 ml, copper ...
