This study investigates water–rock interactions of Taiwan hot springs by analyzing rare earth elements (REEs) concentrations and strontium (Sr) isotopes. REEs were separated from samples using RE resin, their measured HR-ICPMS. Strontium was isolated SrSPEC the isotopic ratio determined MC-ICPMS. The ΣREE in ranges 3.17 ng/L to 29.7 µg/L, with highest levels found Tatun Volcano Group, followed sedimentary metamorphic regions. primary factors controlling REE compositions are lithology pH. patterns can be categorized into five types, indicating that affected various mechanisms. most distinct spring Volcano, Ginshan, Kuantzuling. 87Sr/86Sr ratios range 0.70468 0.71730, radiogenic originating regions, reflecting nature parent rock interacting water. Seawater intrusion preferential weathering carbonate also have minor effects on Sr isotope composition. findings indicate types surrounding rocks pH values significantly influence Taiwan’s springs.

This study evaluates the environmental and health hazards associated with presence of Fe, Cr, Zn, Cu, Pb in agricultural soils from Makkah region western Saudi Arabia. Soil samples were collected 32 farms predominantly cultivating dates vegetables analyzed for heavy metals (HMs) using inductively coupled plasma-atomic emission spectrometry (ICP-AES). Multivariate statistical analysis, Geographic Information Systems (GIS), various contamination indices employed. The average HM concentrations arranged descending order as follows: Fe (35.138 mg/kg), Zn (69.59 Cu (55.13 Cr (47.88 (6.09 mg/kg). Contamination indicated considerable enrichment deficient to minimal other HMs, though a few individual showed higher factor (EF) values. Risk assessments revealed low-level risk HMs soils. analyses suggested that primarily originated natural geological processes, anthropogenic contributions particularly evident Cu. Hazard index (HI) values ranged 0.0003 0.0691 adults 0.003 0.6438 children, remaining below threshold 1.0, which indicates no significant non-carcinogenic risk.

In this paper, grain size mineralogical geochemical characteristics sediments from River were investigated. results show following: (1) average coarse (65.5% sand, 23.6% silt), sorting overall poor; skewness mostly positive, kurtosis wide, which reflects obvious river sand deposition. (2) mineral composition dominated by quartz (38.4%), feldspar, plagioclase followed clay minerals, content carbonate minerals relatively low; in illite high 83.3%, while chlorite slightly higher than kaolinite, smectite very low. chemical index less 0.4, indicating that mainly iron-rich magnesium illite. (3) weathering (CIA) low, implying are a weak–moderate state physical weathering. Comprehensive analyses further revealed process was influenced both lithology, i.e., sediment not only dry, cold but also granites exposed over large areas. can provide scientific references in-depth research climatic effects

Munition disposal practices have significant effects on microbial composition and overall soil health. Explosive contamination can disrupt communities, leading to abundance richness changes. This study investigates the diversity of soils roots from sites with a history ammunition disposal, aiming identify organisms that may play role in bioremediation. Soil root samples were collected two types (through open burning detonation) unpolluted Machachi, Ecuador, over years (2022 2023). High-throughput sequencing 16S rRNA gene (for bacteria) ITS region fungi plants) was conducted obtain taxonomic profiles. There variations bacteria, fungi, plant communities between polluted sites. Bacterial genera such as Pseudarthrobacter, Pseudomonas, Rhizobium more abundant roots, while Candidatus Udaeobacter dominated soils. Fungal classes Dothideomycetes Sordariomycetes prevalent across most samples, Leotiomycetes Agaricomycetes also highly samples. Plant-associated reads showed higher Poa Trifolium particularly at contaminated sites, Alchemilla, Vaccinium, Hypericum Alpha analysis indicated bacterial significantly whereas fungal not different among Redundancy beta site, year, sample type influenced community structure, site being influential factor. Differentially taxa, including bacteria Pseudarthrobacter Paraleptosphaeria Talaromyces, contribute natural attenuation processes explosive-contaminated research highlights potential certain taxa restore environments by explosives.

This study explores for the first time P recovery from poultry litter ash (PLA) using microwave-assisted thermochemical treatment, aiming to improve its bioavailability utilization as a fertilizer. PLA samples, originating laying hens' manure incineration, were subjected microwave treatment with addition of sodium bicarbonate, and their physical-chemical characteristics analyzed X-ray fluorescence (XRF), diffraction (XRD), scanning electron microscopy energy dispersive spectroscopy (SEM-EDS). The results indicate that led formation NaCaPO4 crystals, significant increase in solubility post-treatment, which is crucial plant uptake. Moreover, increasing amorphous content decrease because atoms tend diffuse within silica network. However, this case, interesting glass materials promising optical properties may be obtained. provides novel approach valorizing biowaste contributes sustainable phosphorus management practices.
