However, contamination of these foods poses a significant public health concern. In this study, risk assessment of aflatoxin M1 (AFM1) exposure associated with the consumption of traditional milk and dairy products in Fasa, Fars Province, Iran, was carried out. A total of 180 samples, comprising raw milk, boiled milk, cheese, yoghurt, as well as Doogh and Kashk, two traditional fermented milk-based products, were collected during two seasons of summer and winter and then analyzed using enzyme-linked immunosorbent assay (ELISA). The findings indicated that 85.55% of all samples were contaminated with AFM1 with the mean concentration of positive samples as 251.15 ± 71.97 ng/kg (1.10–453.50 ng/kg). The results also showed that in 68.88% of tested samples, the toxin concentration exceeded the limit set by the national standard of Iran and the European Union standard. Dietary exposure value calculated for the study population was 0.13 ng/kg BW/day. Based on calculations resulting from risk characterization, hazard index (HI), liver cancer risk (LCR), and margin of exposure (MOE) for AFM1 were 0.67, 7.6 × 10<sup>−4</sup>, and 15,291, respectively. For yoghurt consumers, results showed a significant risk for the study population regarding non-carcinogenic and carcinogenicity hazard (HI > 1, LCR > 10<sup>−4</sup>, MOE < 10,000). Yoghurt showed the highest contribution rate for AFM1 exposure in various dairy products due to its higher consumption rates, followed by milk. Based on these results, there are needs for rigorous monitoring and control of cattle feeds to decrease the risk of contamination with aflatoxins.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":544,"journal":{"name":"Environmental Monitoring and Assessment","volume":"197 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2024-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142844900","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}

This study investigates the limitations of double-layer theory for bentonite–organic contaminant interactions through experimental and numerical analysis.

The double-layer theory, particularly Stern's model, has limitations in accurately representing the interaction between bentonite and organic contaminants. The research aims to validate the double-layer equations and investigate the impact of viscosity and cation hydrated radius on the rheological properties of Na-bentonite. The novelty lies in introducing a range of viscosities into the pore fluid to challenge existing double-layer equations. Numerical calculations based on double-layer theory were used to analyze the total interaction energy. The study found that without salt, bentonite showed similar rheological behavior in acetone and alcohol but higher yield stress in glycerol. NaCl up to 0.1 M increased yield stress, while 0.5 M reduced it. KCl had a more pronounced effect on rheological properties than NaCl, highlighting the importance of cation hydrated radius. In soil-organic mixtures, lower viscosity organic chemicals increased yield stress. Despite similar dielectric constants, acetone showed higher yield stress than glycerol at lower concentrations, but at higher concentrations, dielectric constant differences became dominant. The study confirms the limitations of double-layer theory in bentonite–organic contaminant interactions, particularly regarding pore fluid viscosity, though it remains reliable at high contaminant concentrations.</p></div>","PeriodicalId":544,"journal":{"name":"Environmental Monitoring and Assessment","volume":"197 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2024-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142844901","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}

Nowadays, remote sensing imagery has emerged as a useful tool for mapping and tracking LULC changes. Spectral optical indices derived from remote sensing data can provide insightful information about vegetation health, urban expansion, water bodies, deforestation patterns, and many other applications. The present study examines the use of popular optical spectral indices: vegetation index (NDVI), water indices (NDWI and MNDWI), urban indices (UI and NDBI), and bare land index (MNDBI) in threshold-based classification for LULC mapping using Algiers (Algeria) as a case study, and assesses the potential impacts of their spatiotemporal (at a seasonal and annual temporal scales) variations associated with natural seasonal changes and/or the evolution of the city’s fabric. Here, a geo-statistical analysis of the values of the selected spectral indices at the level of each LU-class is conducted, threshold values (that account for seasonal variations) are proposed, and a classification approach (making use of best performing indices) is proposed and tested. Although fast and easy to implement, the proposed threshold-based LULC classification approach was successfully used for mapping LULC for the study zone with a high accuracy (an overall accuracy of 90.20 and a kappa of 0.84 for the demonstration year of 2017). The outcomes of the study heighten the potential and the limitations of the use of spectral indices for LULC mapping practices and consequent applications in environmental and urban studies.</p></div>","PeriodicalId":544,"journal":{"name":"Environmental Monitoring and Assessment","volume":"197 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2024-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142844903","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}

Subsequently, the PWV values derived from the two types of receivers were assessed with the radiosonde and ERA5-derived PWV. Compared with radiosonde, the RMS of the PWV differences for standalone BDS and IGS MGEX receivers was 1.9 and 1.6 mm, respectively. While compared with the ERA5 products, the RMS was 1.5/1.7 mm for IGS MGEX stations and 1.7/1.9 mm for standalone BDS stations. The monitoring performances during rainy and non-rainy days were further analyzed, and negligible differences (less than 0.15 mm) between the PWV accuracies were observed.
