The stable isotope ratios of nitrate (δ15N, δ18O) are widely used as tracers of nitrogen pollution sources.

The scarcity of observed hydro-meteorological data in mountainous catchments further hinders the model's efficiency in water evaluations. This study aims to estimate the freshwater availability via characterizing the water balance employing a distributed MIKE System Hydrological European (SHE) model for the Suketi catchment of the Beas Basin, in Himachal Pradesh, India. For this purpose, the MIKE SHE/MIKE+ based model was developed for the study area using meteorological and basin-specific data. The collected samples from the rainfall, groundwater, and stream water during 2023-2024 were analysed for stable water isotopes, i.e. δ18O and δ2H. The quantitative evaluation established the efficacy of the MIKE SHE/MIKE+ based model with root-mean-square-error, coefficient of determination, Nash-Sutcliffe efficiency, and percentage bias of 76.67, 0.88, 0.92, and -0.32, respectively. The output of the developed model was integrated with the results of a two-component mixing model through the measured values of δ18O and δ2H. The local meteoric water line (LMWL: δ2H = 8.17 · δ18O + 13.11) reveals the different climatic conditions due to lower temperatures and higher latitude of the study area vis-a-vis global average. The validated water balance of the Suketi catchment infers adequate freshwater availability in the catchment with more than 74 % as baseflow to the Suketi river and evapotranspiration accounted for 64.42 % of water loss into the atmosphere.","PeriodicalId":14597,"journal":{"name":"Isotopes in Environmental and Health Studies","volume":" ","pages":"239-263"},"PeriodicalIF":1.1,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143779999","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Rice is a primary diet source for over 50 % of the global people, particularly in Asia. Thus, the estimation of the annual effective dose due to the ingestion of 226Ra, 232Th, and 40K in rice has become an important area of study in food safety and human health risk assessment. The activity concentrations of 226Ra, 232Th, and 40K in rice were found by gamma spectroscopy using sodium iodide scintillation (NaI (Tl)) and high purity germanium (HPGe) detectors. Even if the activity concentration of 40K in Thailand rice is higher than 400 Bq kg-1, the other present rice investigations demonstrate that the activity concentrations of 226Ra, 232Th, and 40K are smaller than the world limit values of 35, 30, and 400 Bq kg-1, respectively. Although the people of the Asia continent consume the highest rate of rice, the highest ingestion annual effective dose due to these radionuclides through consuming rice was found in Africa. It was found that the highest ingestion annual effective doses of 226Ra, 232Th, and 40K from eating rice were 645.49 μSv y-1 in Thailand, which is greater than the average value of 290 μSv y-1 worldwide.

Stable carbon (δ13C) and nitrogen (δ15N) isotope analysis has been used to study how silver carp impact native ecosystems, but lipids in fish tissues commonly bias their δ13C values. Chemical lipid extraction and mathematical equations that normalise δ13C values for lipid content can account for this bias, but have not been assessed for silver carp. We examined δ13C, δ15N, and C:N ratios before and after chemical lipid extraction using 2:1 chloroform:methanol in silver carp muscle and whole fish collected along the Mississippi River. We used linear and natural log models to estimate lipid-extracted δ13C values in silver carp muscle and whole fish samples based on their non-lipid-extracted δ13C values and elemental C:N ratios. Arithmetic models were evaluated for best fit, parsimony, and accuracy between mathematically normalised and chemically lipid-extracted δ13C values. Chemical lipid extraction increased silver carp δ13C values and decreased C:N ratio in muscle and whole fish, and increased δ15N values in whole fish but not fish muscle. While both linear and natural log models accurately estimated lipid extracted δ13C values, natural log models provided better fit and parsimony throughout a wide range of C:N ratios. These results confirmed the need to account for lipid effects on δ13C values in silver carp. Moreover, our study will allow researchers to conduct isotopic analysis without the added time and cost of chemical lipid extraction and facilitate the comparison of silver carp muscle and whole fish isotopic values across studies.","PeriodicalId":14597,"journal":{"name":"Isotopes in Environmental and Health Studies","volume":" ","pages":"181-197"},"PeriodicalIF":1.1,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143065614","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dragonflies (Odonata) are considered to be good indicators of water quality; however, research on dragonflies as potential indicators of radioactivity is scarce. The aim of this study was to evaluate dragonflies as potential biological indicators of ionising radiation in nature by measuring 137Cs activity concentrations in the dragonfly and river water samples. Altogether, 11 collective samples of dragonflies were collected from the bank of the Mura-Drava-Danube Biosphere Reserve, in the area of Virovitica-Podravina County. Following the initial sample preparation, the gamma spectrometry technique, employing an ORTEC HPGe detector system, was utilised to determine the activity concentrations of 137Cs. The results show that the activity concentrations of 137Cs in the river water were in the range from 4 to 13 Bq/m3. The results of dragonfly samples showed that 137Cs was in the range from 1.7 to 3 Bq/kg. This was more than a hundred times higher than in the river Drava water.
