“…The radioactive metal Uranium has a silvery color and is found in water, soil, and rocks contain traces of Uranium. Three isotopes make up natural Uranium: 234 U, 235 U, and 238 U but 238 U are the most common types of it [1]. 238 U makes up more than 99 percent of all Uranium found in nature and alpha radiations are emitted during the decay process.…”

Radioactive material, especially Uranium, is very dangerous for human beings, creatures, and plants. It has been documented that the groundwater of the Dera Ghazi Khan Division in Punjab is contaminated with 238U. In this communication, the groundwater of the Tehsil Taunsa located at Indus River has been investigated. 144 samples of drinking water were collected from 48 villages/towns located in the area of about 500 km2 of the city. The samples were collected in the month of June, August and November, to concentrate on the temperature impact over the Uranium concentration. All samples were analyzed for 238U concentration using a fluorometric technique. The fluorometric technique was applied after pre-treatment of the sample. The analysis of the result revealed that groundwater obtained from this region contains a high value of 238U contents. Among the 48 trials, 26 samples were found below the permissible limit, while the remaining samples contained 238U contents above the permissible level. The sample collected from areas like, Qarim Wala, Jhoke Jamki, Basti peer, Tibi Qaisrani, Pehar Adda & Malana contained even up to the alarming level (30µg/L to 54µg/L). In addition, it was observed that the sampling period had a significant effect on the contents, which were most prominent in June. This area being almost annually flooded by water from Rodh Kohi, who originated from Koh-e-Suleiman, may lead to such a high concentration of 238U. The additional reason could be the topographical and geological structure of the earth from which the samples were collected.

“…Since the formation of our planet, uranium has been a component of its crust. It is found in various concentrations in the rock, soil, air, and water of the area, and it enters the body through the air, food, and water [1] . All three of the uranium isotopes that make up natural uranium—99.284% U-238, 0.711% U-235, and 0.005% U-234—are radioactive.…”

Objective: The main goal of the study was to find whether pumpkin (Cucurbita pepo) extract has any preventive or antioxidant properties against acute uranyl acetate (UA)-induced reproductive cytotoxicity. Material and Methods: Four groups each, including 10 adult male rats, were randomly assigned. (GI): the control group was given 1 ml of purified water orally for 30 days. (GII): Rats were given orally, a single dose of 150 mg/kg b.w. UA (GIII): Rats consumed 40 mg/kg b.w. of pumpkin seed extract (PSE) orally every day for 30 days. (GIV): Rats received a single dose (150 mg/kg b.w.) of UA plus a daily oral dose of PSE (40 mg/kg b.w.) for 30 days. Animal sacrifice was used for oxidative stress and histopathological study. Results: Showed significantly (p ≥ 0.001) elevated malondialdehyde levels in the GII group (6.19 ± 0.4), while GIII and GIV showed no significant differences. Glutathione peroxidase showed a significant (p ≥ 0.001) decrease (2.55 ± 0.2) in the GII group, while in groups (GIII and GIV), it showed a significant (p ≥ 0.001) increase (4.61 ± 0.16, 4.28 ± 0.032), respectively. The histopathological study for GII groups showed sloughing of epithelial cells lining the seminiferous tubules with a decrease in the number of spermatozoa in some tubules. Many sections revealed hyperplasia of the epithelial cells lining the seminiferous tubules with necrosis. The GIII and GIV groups showed normal histological structures with an increase in spermatogenesis in the testes and epididymis tissues. Conclusion: We concluded that UA causes oxidative stress and histopathological alterations in the rat reproductive system. Pumpkin extract plays a role in improving the activity of the reproductive system.

“…However, the pH of groundwater is greatly decreased, thus changing the original geochemical environment, and the resultant uranium ions might enter the food chain and cause degenerative changes to human lungs, bones, and nerve tissues and even cause inherited genetic defects. [4][5][6][7][8] Therefore, it is urgent to remediate uranium-contaminated groundwater in acid in situ leach uranium mines. Many technologies such as chemical reduction fixation, adsorption, ion exchange, permeable reactive barriers, photocatalysis, electrocoagulation and biological methods have been developed to alleviate U(VI) contamination.…”
