Based on the data from paired soil, vegetable, rice and urine samples from southern China, this study quantified the transfer of Cd in the soil-food-human system. There were probabilities of 75​% that the urinary Cd from local residents (3.11 ​± ​1.98 ​μg ​g⁻¹ creatinine) would exceed the safety threshold, with rice consumption being the largest contributor at 94​%. A probabilistic physiologically based toxicokinetic (PBTK) model was used to optimize the strategies for reducing the Cd body burden through the food-blood-plasma-liver-kidney pathway. The liver (21%) and kidneys (37%) are the principal sites of Cd accumulation in the humans, with age and gender being the major controlling factors. Kidney Cd significantly correlates with urinary excretion, making urinary Cd a crucial biomarker for Cd dietary intake. Adult females who consume less rice are more susceptible to Cd exposure due to lower Zn levels in their bodies, which enhance Cd absorption. Even with lower rice consumption, the reduced Zn storage in females increases the risk of Cd accumulation because Zn normally helps reduce Cd absorption. To protect 74% of adult males and 81% of adult females from excessive Cd body burden, it is recommended that local residents consume more food rich in Zn, targeting at least 6.25 ​mg Zn ​d⁻¹ for adult females and 5.15 ​mg Zn ​d⁻¹ for adult males.</div></div>","PeriodicalId":94356,"journal":{"name":"Soil & Environmental Health","volume":"3 2","pages":"Article 100146"},"PeriodicalIF":0.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143776955","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is particularly true for the influences of different farming practices on their taxonomic distribution. This study aimed to investigate the influence of organic and conventional farming on AMF diversity in the rhizosphere soils of three crops includng mango, citrus and cucumber from Oman. Spore morphological analysis and internal transcribed spacer (ITS) sequencing were used to identify AMF species diversity. Spore morphological analysis revealed a total of 9 families, 20 genera, and 36 species, and in general, organic farming samples showed higher diversity than conventional farming samples. The ITS sequencing analysis showed the presence of 6 families and 12 genera, with organic farming samples being significantly more diverse than conventional farming samples based on the number of taxa and Shannon H index. Both spore morphology and ITS sequencing data showed that the families Diversisporaceae and Glomeraceae were the most abundant among all the treatments. Compared to their respective conventional soils, the mean percent mycorrhizal inoculum potential was significantly higher for the organic soils under cucumber, with the root colonization being also higher for organic soils under citrus. A quick colonizer trap culture method was used to determine which AMF species colonized and established in the roots after 14 days. AMF species including <em>Rhizoglomus intraradices</em> and <em>Septoglomus viscosum</em> quickly infected cucumber, and could potentially be used as biofertilizer inocula. The results help to understand the AMF diversity across different farming systems in semiarid and arid regions, as well as to promote and develop sustainable agriculture in these regions.</div></div>","PeriodicalId":94356,"journal":{"name":"Soil & Environmental Health","volume":"3 2","pages":"Article 100140"},"PeriodicalIF":0.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143684533","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These include a lack of green space, poor access to healthy fruits and vegetables, and high exposure to environmental contaminants. Access to soils with low contaminant bioaccessibility is critical to addressing these concerns. This is complicated due to conflicting guidance on what constitutes safe soil and how to improve the quality of urban soils. This review details the basics of the hazards associated with two ubiquitous urban contaminants: Pb and PAHs. The literature on significant exposure pathways and potential bioavailability of these contaminants is discussed. Guidance and regulatory values for both Pb and PAHs are shown and vary widely. Soil concentrations of these contaminants are often exceed regulatory values. Data from studies on urban soils for contaminant concentrations and availability reduction are presented. Use of organic amendments including compost- and biosolids-based soil products, along with gardening in raised beds are acceptable practices for growing food in potentially-contaminated soils. Yield increases associated with their use has been reported. The feedstocks for these amendments are readily available in all urban areas. Because these amendments typically have lower concentrations of contaminants than urban soils, their use will decrease total concentrations of contaminants and has been shown to improve soil and ecosystem health. Bioaccessible fractions of contaminants may also be reduced. Thus, these amendments appear to be a way to safely and productively increase urban green space. In addition, the use of residual-based soil amendments will result in additional environmental benefits due to waste diversion from landfills.</div></div>","PeriodicalId":94356,"journal":{"name":"Soil & Environmental Health","volume":"3 1","pages":"Article 100127"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143135959","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Studies on their environmental fate are absent for New Zealand soils, which often receive animal waste effluent including poultry litter. Laboratory studies were performed to evaluate the sorption and dissipation behavior of two fluoroquinolones (ciprofloxacin and enrofloxacin) in three New Zealand pastoral soils with and without poultry litter amendment at low and high levels (1 and 5%, w/w). Results of the batch sorption studies suggest that isotherms were best described by Freundlich model, Freundlich coefficients for the compounds varied from 312 to 62,163 ​g^1−N L^N kg⁻¹ in the soils, with cation exchange being the dominant sorption mechanism. Addition of poultry litter (5%, w/w) decreased the sorption affinity of fluoroquinolones to soils, which was mainly related to pH-induced changes in compound speciation. Results of incubation studies performed under aerobic conditions show that dissipation half-life was highly variable (15–378 days). A dehydrogenase assay performed as an indicative of microbial activity during incubation studies indicates that despite lower microbial activity, dissipation was faster in subsoils (30–40 ​cm), attributing to higher compound bioavailability due to lower sorption ability of the subsoils. Augmenting poultry litter (5%, w/w) increased dissipation, due to a combination of lower sorption and higher microbial activity. High sorption in New Zealand soils may reduce fluoroquinolone's toxicity to exposed terrestrial organisms. However, high persistence may represent a relevant antibiotic reservoir in a long term, posing risks to terrestrial and aquatic ecosystem health and thus warranting further elucidation.</div></div>","PeriodicalId":94356,"journal":{"name":"Soil & Environmental Health","volume":"3 1","pages":"Article 100125"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143095596","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This approach involves a first-time bilinear decomposition of soil mid-IR absorbance spectra using nonnegative multivariate curve resolution (MCR) with an alternating least square (ALS) algorithm. An MCR-ALS-derived component signifies a chemically meaningful combination of soil constituents. This new mechanistic model has been developed to link the soil composition, expressed in terms of ratios of MCR-ALS-based concentration scores of the identified components, to soil TOC value. Nonnegative MCR-ALS decomposition, performed for 213 mid-IR absorbance spectra of soil samples collected in the north and south of Israel, yielded four components. Fitting the mechanistic model-derived TOC to the experimental TOC values exhibited a TOC content threshold that affected model performance. TOC content &lt;1.0 % w w⁻¹ was represented by the root mean square deviation of 0.18% with 62% of the variance being explained, whereas for larger TOC values, a sharp decline in model performance was observed. The existence of this TOC threshold in determining model performance suggested that successful TOC modeling (below 1%) could be indirect and related to IR spectral fingerprints of minerals binding soil organic matter (SOM) and forming organo-mineral complexes. Thus, a SOM fraction having weak interactions with soil minerals was poorly accounted for in some soil samples. The dependency of the model performance on soil TOC contents suggests that it might be possible to differentiate between soil samples based on their different dominating SOM pools, mineral-associated ones and those having weak interactions with minerals. Further studies, especially in soils with high SOM content, are needed to validate our findings.</div></div>","PeriodicalId":94356,"journal":{"name":"Soil & Environmental Health","volume":"3 1","pages":"Article 100123"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143135958","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, aggregate size separation was conducted on two contaminated soils that underwent phytoextraction using Zn/Cd hyperaccumulator <em>Sedum plumbizincicola</em> over six consecutive seasons. The dynamic changes in Zn and Cd concentrations, chemical fractionations and isotope compositions in soil aggregates were investigated. As phytoextraction proceeded from the first (C1) to the sixth (C6) season, shoot Zn displayed a marginally heavier isotope composition despite the essentially constant Zn isotope composition of bulk soils and the 50–250, 5–50, 1–5, and &lt;1 ​μm aggregate size fractions. Most likely, this results from moderate depletion of Zn in the bulk soils (by ​≤ ​21%) and gradual release of heavy Zn isotopes into soil bioavailable pool due to soil acidification and Zn exchange during repeated phytoextraction.

Rayleigh modelling produced similar Cd isotope fractionation factors for aggregates of different size fractions, indicating that similar mechanisms controlled Cd release from soil aggregates. In contrast to other plants preferring light Cd isotopes, Zn/Cd hyperaccumulator continuously took up heavier Cd isotopes from soils. The results were due to the enhanced root exudation to mobilize more Cd from soil solids and organic ligands excreted from roots preferentially complexed heavy Cd isotopes based on density functional theory.

With over 15,000 different PFAS compounds being identified globally, their toxic effects and half-life spanning from 72 ​h to 8.5 years in humans are a serious concern. Bioremediation has emerged as an environmentally-friendly and cost-effective approach for PFAS degradation. However, there is still limited understanding of PFAS interactions with microorganisms and the roles of promising microbes in transforming PFAS into non-toxic end products. The knowledge about biotransformation of PFAS is essential to ameliorate the adaptation of microorganisms to local matrix and environment as well as to strengthen the natural enzymatic pathways and activities at a commercial scale, which is a major challenge. This review aims to address these gaps by providing a comprehensive analysis of recent developments in the bioremediation of PFAS-contaminated soil and water systems. The review focuses on the capabilities of phytoremediation, bioelectrochemical systems, and microbial species, including bacteria, fungi, and microalgae. Additionally, this study offers an in-depth overview of PFAS sources, their physicochemical characteristics, and their environmental fate and transport. Furthermore, it examines microbial metabolic activity, the formation of degradation intermediates, the role of co-metabolism, and the behaviour of microorganisms under PFAS stress as well as highlights future research directions. The key findings from this review include: 1) microbial community composition, field application, presence of co-substrate and cationic complexation govern biotransformation and fate of PFAS, 2) long chain PFAS are more susceptible to accumulate in the roots due to high hydrophobicity, and 3) algae-bacteria symbiotic relationships reduce microalgae growth inhibition and stimulates PFAS removal. Overall, this review emphasizes the potential of bioprocesses for large-scale PFAS bioremediation, contributing to environmental protection and mitigating the risks associated with PFAS contamination.</div></div>","PeriodicalId":94356,"journal":{"name":"Soil & Environmental Health","volume":"3 1","pages":"Article 100126"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143095597","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
