Different natural and anthropogenic processes cause pollution of various water bodies worldwide creating numerous health problems for humans. This causes serious concern as is a basic necessity to all living beings, needs be adequately monitored managed prevent its contamination. If found contaminated, the cleaned using suitable treatment methods keeping in view WHO regulations before it intended purpose (drinking, irrigation, etc.). Application different ICP-MS techniques such classical...
Tritium (3H) in Earth's precipitation is vigilantly monitored since historical nuclear bomb tests because of radiological protection considerations and its invaluable role as a tracer the global water cycle quantifying surface, groundwater, oceanic fluxes. For hydrological applications, accurate knowledge 3H contemporary local prerequisite for dating critical zone calibrating hydrogeologic transport groundwater models. However, tritium input hard to constrain due few observation sites. We...
Due to its short half-life (87 days), naturally occurring radio-sulfur (35S) is applicable as aqueous environmental tracer for investigating groundwater residence times shorter than one year. Being a pure β-decaying radionuclide, 35S detected straightforwardly by means of liquid scintillation counting (LSC). The rather low activities in natural waters require (i) careful sample preparation aiming at extracting 35SO42- from large-volume water samples (ca. 20 L) resulting ready LSC measurement...
An unprecedented heatwave affected East Antarctica between 15 and 19 March 2022, triggering record-high temperatures from the coastal regions to Antarctic plateau. The event was caused by an intense atmospheric river that transported heat moisture central southwestern subtropical Indian Ocean at lower latitudes into interior of continental Antarctica. Although poleward advection ceased after 18 March, a counterclockwise flow clouds around blocking anticyclone trapped residual over This led...
Research on groundwater residence times is crucial for assessing infiltration rates and aquifer vulnerabilities, both playing a vital role in sustainable water resource management. This study aimed at advancing the use of short-lived cosmogenic radionuclide 35S (“radio-sulfur”, t1/2 = 87.4 d) determining less than one year. The results show that provides valuable tool evaluating times, rates, vulnerabilities. preconcentration 35SO42- using an anion exchange resin...
Abstract Background Inductively coupled plasma mass spectrometry (ICP-MS) techniques have been widely used for analysis of long-lived environmental radionuclides. In this paper, we present an optimization the sector field (SF)-ICP-MS technique 226 Ra in groundwater samples using a method pre-concentration radium water samples. Methods The separation protocol and sequential application ion exchange extraction chromatography optimized, related polyatomic interferences matrix effects affecting...
Rare events search experiments, like those dedicated to the direct evidence of dark matter or neutrinoless double beta decay, are among most exciting challenges modern physics. The sensitivity such experiments is driven by background, which depends substantially on radiopurity materials used for experimental apparatus. Cutting edge measurement techniques needed a fast, sensitive and efficient screening these certification their production. Trace element measurements high quick execution...
Abstract Tritium, a radioisotope of hydrogen, is an ideal tracer for groundwater and surface dating tracking since it part the water molecule. The knowledge history tritium in precipitation recharge key link calculation age. However, records are usually sparse discontinuous, especially regions like South America, often need to be reconstructed. To solve this problem, different reconstruction methods input function have been analysed compared. Clustering Global Network Isotopes Precipitation...
Abstract 3 H enters the hydrologic cycle after oxidizing in 1 HO molecule and it constitutes a very useful tracer for hydrological studies. One of these applications is streamflow component separation, which provides information to understand cycle. This application based on fact that contents precipitation (runoff) tend be markedly higher than those groundwater (baseflow) because decreasing activity last as consequence radioactive decay. The main objective this paper test hydrograph...
Tritium (³H) is a vital tracer in isotope hydrology and environmental studies, necessitating accurate precise low-level detection methods. This study evaluated the performance of new Hidex ULLA Liquid Scintillation Counter for ultra-low-level tritium assays water samples. The optimization instrumental parameters enabled reproducible
Rationale Tritium ( 3 H) is an important hydrological tracer that has been commonly used for over 60 years to evaluate water residence times and dynamics in shallow/recent groundwaters, streams, lakes the ocean. We tested analytical performance of 78 international laboratories engaged low‐level H assays age dating monitoring environmental waters. Methods Seven test waters were distributed by IAEA tritium laboratories. Set 1 included a tritium‐free groundwater plus three ultra‐low samples...
Research on groundwater residence times is essential for evaluating abstraction rates and aquifer vulnerabilities, hence, sustainable water resources management. Naturally occurring radionuclides are suitable tools related investigations. While the applicability of several long-lived investigation long-term processes has been demonstrated frequently, tracer-based approaches studying less than one year have not fully exploited. That due to rather small number applicable that show adequately...
