Phosphogypsum is a byproduct of phosphate fertilizer production, and more than 700 million metric tons have accumulated on 2,500 ha in Florida. Field research was conducted to compare the benefits of capping phosphogypsum with overburden (up to 15 cm in depth) from mined sites versus treatment of the phosphogypsum with minimal amendments. After four growing seasons, vegetation cover was excelle...
Abstract Many industrial processes produce high fluoride (150–450 mg/L) containing effluent. It may be recovered from the processing plants at source. One effective technology is selective adsorption waste stream. Metal-organic frameworks (MOFs) are crystalline compounds with surface area, pore volume, and tuneable channels suitable adsorbents. This study used zirconium fumarate (ZrFu) MOF to r...
fluoride is one of the most important elements in the composition of teeth and bones. this element can enter the body via different ways. however, drinking water is the most important way to receive fluoride by a lot of people. an increase in fluoride level in the body causes dental fluorosis and its absence leads to teeth decay. standard rate of fluoride in drinking water is determined by the ...
A novel annexin V derivative (Cys-Annexin V) with a single cysteine residue at its C-terminal has been successfully labeled site-specifically with NOTA-maleimide aluminum [18F]fluoride complexation and evaluated it as a novel apoptosis agent in vitro and in vivo. The total synthesis time of 18F-AlF-NOTA-MAL-Cys-Annexin V from [18F]fluoride was about 65 min. The tracer was stable in vitro and it...
BACKGROUND The use of non-invasive imaging to identify ruptured or high-risk coronary atherosclerotic plaques would represent a major clinical advance for prevention and treatment of coronary artery disease. We used combined PET and CT to identify ruptured and high-risk atherosclerotic plaques using the radioactive tracers (18)F-sodium fluoride ((18)F-NaF) and (18)F-fluorodeoxyglucose ((18)F-FD...
BACKGROUND We examined the uptake and sorption of aluminium (Al) and fluoride (F) by green algae under conditions similar to those found in the effluents of the aluminium industry. We took into account the speciation of Al in the medium since Al can form stable complexes with F and these complexes may play a role in the uptake and sorption of Al. We compared the capacity of four species of gree...
Abstract Long-term consumption of tea with high fluoride (F) content has a potential threat to human health. The application different amounts biochar reduce F accumulation in leaves been little studied. In this study, pot experiment was conducted investigate the effect (0, 0.5%, 2.5%, 5.0%, 8.0%, and 10.0%, w/w) on during plant growth. Changes quality, soil fraction, properties caused by relat...
