Comparative Assessment of Live and Dead Thermophilic Bacterial Isolates of Surya Kund Hot Spring, Yamunotri for the Bioremediation of Cu ²⁺

Geomicrobiology Journal, Journal Year: 2025, Volume and Issue: unknown, P. 1 - 8

Published: Feb. 27, 2025

Heavy metal pollution, especially copper (Cu2+) contamination, poses significant threats to ecosystems and human health due its persistence, bioaccumulation, toxicity. Traditional methods of remediation are often expensive generate secondary necessitating the exploration eco-friendly alternatives. Bioremediation, leveraging metabolic capabilities microorganisms, offers a promising solution. This study investigates bioremediation potential ions using thermophilic bacterial isolates from Surya Kund Hot Spring in Western Garhwal Himalayas (Uttarakhand). Both live dead cells were tested for their ability remove Cu2+ contaminated solution, showing significantly higher efficiency. Isolates Y12-II (Pseudomonas alloputida strain BG-3) Y10 (Paenibacillus thiaminolyticus NBRC 15656) exhibited highest rates, achieving up 51.97% 50.82% removal, respectively. The findings suggest biomass approach passive heavy contamination. However, recent advancements microbial isolation, genetic engineering, metagenomics have expanded our understanding resistance mechanisms enhanced strategies. reveals as sustainable address contributing environmental restoration public safety.

Comprehensive analysis of groundwater hydrochemistry and nitrate health risks in the Baiquan basin, Northern China

PeerJ, Journal Year: 2025, Volume and Issue: 13, P. e19233 - e19233

Published: April 15, 2025

Groundwater is a crucial water source and strategic resource, essential for sustaining both urban rural livelihoods, supporting economic social development, maintaining ecological balance. This study investigates the hydrochemical properties controlling factors of groundwater in Baiquan basin (BQB) by analyzing quality data collected during dry wet periods. Additionally, suitability drinking agricultural irrigation was evaluated. The findings reveal that BQB generally weakly alkaline primarily consists hard-fresh water. Although there are seasonal variations main ion concentrations, HCO 3 − Ca 2+ predominant anions cations, respectively. Consequently, type mainly -Ca⋅Mg type, with secondary classification SO 4 ⋅Cl-Ca ⋅ Mg. composition influenced dissolution carbonate silicate minerals, as well cation exchange processes. it affected anthropogenic inputs, particularly from use fertilizers. assessment results indicated all samples classified either good or moderate, significant majority falling into category. northern section exhibited lower entropy weight index (EWQI) values season comparison to season. For irrigated agriculture, serves high-quality throughout rainy seasons. Furthermore, non-carcinogenic risks notably concentrated north-western south-eastern regions area. Health associated nitrates elevated Notably, infants were significantly high across seasons substantially exceeded those children adults. These provide valuable scientific insights management development resources BQB.

Assessing heavy metals and developing a fingerprint for Mahikeng paints using ICP-MS analysis: implications for environmental health

Research Square (Research Square), Journal Year: 2024, Volume and Issue: unknown

Published: Oct. 8, 2024

Despite global efforts to mitigate lead in paints, studies reveal persisting levels above safety thresholds household paints many nations. Alongside lead, other heavy metals (HMs) pose health risks. The study aims assess content and levels, develop a fingerprint for Mahikeng, the capital of North West Province, South Africa, using ICP-MS analysis. We purchased analyzed 30 paint samples from Mahikeng. most prominent nontoxic elements detected are Nitrogen (N), Calcium (Ca), Iron (Fe), Carbon (C), Aluminum (Al), Phosphorus (P). Lead concentrations ranged 0 ppm 4.17 ppm, below Africa's 600 MPLL. Other HMs included Beryllium (Be), Chromium (Cr), Nickel (Ni), Arsenic (As), Cadmium (Cd), Antimony (Sb), Mercury (Hg), as well radionuclides Barium (Ba), Strontium (Sr), Thorium (Th), Uranium (U). Their range 810.57 with found at relatively low levels. obtained Pb isotopic ratios rare earth (REE) patterns were used fingerprint. These findings offer insights into environmental implications contamination by identification their sources. This research contributes sustainable cities communities promoting responsible consumption production practices, enhancing quality education on health, supporting good well-being through reduction hazardous exposures.
