“…Nuclear wastewater containing radioactive uranium with chemical toxicity and non-biodegradability properties is considered to be dangerous to the ecological environment. , Radionuclide uranium mainly exists in the water environment in the form of U(VI) ions. It not only severely damages the water and soil environments but is also harmful to the human nervous, circulatory, and urinary systems. − The United States Environmental Protection Agency (USEPA) clearly requires that the safe concentration level of U(VI) in drinking water be 30 ppb . Therefore, it is urgent to develop a method for the detection of U(VI) with high sensitivity and selectivity in water environments.…”

Radioactive U(VI) in nuclear wastewater is a global environmental pollutant that poses a great threat to human health. Therefore, it is of great significance to develop a U(VI) sensor with desirable sensitivity and selectivity. Inspired by electron-donating group modification for enhancement of binding affinity toward U(VI), we report an amine group functionalization of UiO-66-NH 2 , using a low-cost, environmentally friendly, and lowtemperature NH 3 plasma technique as a fluorescence switching nanoprobe for highly sensitive and selective detection of U(VI). The resulting amine-functionalized UiO-66-NH 2

“…The low radioactive background feature of host formation may also be the primary cause of the low concentrations of U and Th in the measured samples, specifically U in the range from 9 to 3595 and a mean value of of 992 ng L −1 while Th is lower than detection limit. The results show that the average concentration of U is about 300,000 times lower than the allowable limit in drinking water of 30,000 µg L −1 (370 Bq L −1 ) [57,58]. For comparison, the potable groundwater in Uttarakhand state of India has uranium concentrations between 0.02 ± 0 µg L −1 63.7 ± 4.3 µg L −1 [58].…”

There are eight famous thermal water sources, with medium temperature, neutral pH, high ranges of TDS values located in different carbonate formations in Northern Vietnam. The chemical composition results showed the major elements present were Na, K, Mg, Ca, Sr, while trace amounts of rare earth elements (REE), Ag, As, Pb, Th, U were observed. The 210Po activity concentration and the annual committed effective doses for adults, children, and infants in all study areas were far less than 100 mBq L−1 and 0.1 mSv y−1, respectively. Some significant correlations between 210Po and other chemical components have been observed.

“…The uranium concentration in groundwater is also observed changing with seasons, as reported from India's different places [35][36][37]. Due to other heavy metals and major ions present in the groundwater, human health hazard risk has also been recorded [38][39][40][41][42][43].…”

Uranium concentration has been estimated in 31 groundwater samples collected from the Nalbari district of Assam in pre-monsoon and post-monsoon season. Fourteen other water quality parameters have also been monitored to study their correlation with uranium. The uranium concentration varies from 0.3 to 7.1 µg/L with the mean value of 2.15 µg/L in pre-monsoon and 0.6–10.3 µg/L with the mean value of 2.75 µg/L in the post-monsoon season. The higher concentration of uranium in post-monsoon may be ascribed to the dissolution of uranium from soil sediments in the rainy season. It has been observed that the uranium content in both seasons is far lower than the WHO (2011) permissible limit of 30 µg/L. In both seasons, nitrate, sulphate, and especially phosphate show a positive correlation with uranium, which may be due to different agricultural activities. Agricultural nitrate and phosphate fertilization might be the carrier of uranium in groundwater through dissolution. For all life stage groups, the annual effective dose was appeared to be far below the WHO (2011) prescribed limit of 100 µSv/y. In consideration to adults, the ingestion dose for infants was turned out to be higher. The carcinogenic and non-carcinogenic risk was less than the permissible limits for both children and adults. Both dose value and risk indices were found higher in the post-monsoon season.
