The Ramsar Convention on Wetlands designates over 2,000 sites of international importance, providing crucial habitats for diverse species. Uluabat Lake, faces anthropogenic pressures such as urbanization, agriculture, and industrialization, affecting its ecological integrity. Using multi-temporal Landsat 7 9 satellite images from 2002 2022, along with 2019 management plans, we assessed land use/land cover (LULC) changes in the lake's catchment area. Data were pre-processed ENVI stored ERDAS Imagine. We employed pixel-based image analysis maximum likelihood classification (MLC) to generate LULC maps evaluated accuracy using ground truth data kappa coefficient. Our findings revealed a 15.8% reduction lake area, 136.1 km² 114.5 primarily due sediment transport surrounding agricultural tributary streams. Urban-agricultural reed-swamp areas increased by 74.7% 59.6%, respectively, while shrubs forests declined 35.64%, largely reed conversion agriculture Mustafakemalpaşa River delta. Overall ranged 88.2% 91% coefficient 0.81 0.82. These transformations highlight increase swamp decrease emphasizing need effective conservation practices.

Groundwater serves as a primary water source for various purposes. Therefore, aquifer pollution poses critical threat to human health and the environment. Identifying aquifer's highly vulnerable areas is necessary implement appropriate remedial measures, thus ensuring groundwater sustainability. This paper aims enhance vulnerability assessment (GWVA) manage quality effectively. The study focuses on El Orjane Aquifer in Moulouya basin, Morocco, which facing significant degradation due olive mill wastewater. maps (GVMs) were generated using DRASTIC, Pesticide SINTACS, SI methods. To assess effectiveness of proposed improvements, 24 piezometers installed measure nitrate concentrations, common indicator contamination. aimed GWVA by incorporating new layers, such land use, adjusting parameter rates based comprehensive sensitivity analysis. results demonstrate increase Pearson correlation values (PCV) between produced GVMs measured concentrations. For instance, PCV DRASTIC method improved from 0.42 0.75 after adding use layer Wilcoxon method. These findings offer valuable insights accurately assessing with similar hazards hydrological conditions, particularly semi-arid arid regions. They contribute improving environmental management practices, long-term sustainability aquifers.

The widespread presence of arsenic (As) and fluoride (F-) in groundwater poses substantial risks to human health on a global scale. These elements have been identified as the most prevalent geogenic contaminants northern Mexico. Consequently, this study aimed evaluate ecological associated with content As F- Meoqui-Delicias aquifer, which is one Mexico's emblematic irrigation districts. Concentrations were measured 38 samples using ICP-MS ion chromatography, respectively. Overall, these showed similar trend across revealing positive correlation between them pH. concentration ranged from 5.3 μg/L 303 0.5 mg/L 8.8 mg/L, Additionally, levels surpassed established national standards for safe drinking water 92% 97% samples, Given that used both agricultural purposes activities, also assessed posed by Monte Carlo simulation Species Sensitivity Distribution. findings disclosed significant noncarcinogenic risk exposure F-, well an unacceptable carcinogenic through consumption adults children. Furthermore, high aquatic species was medium sampling sites. Therefore, provide valuable information Mexican authorities international organizations (e.g., WHO) about adverse effects any without treatment region represents health.

Introduction The groundwater in arid countries such as Egypt represent the main water resources desert regions due to long distance between these (oasis) and Nile River. Contamination of limited with toxic metals threaten health individuals regions. Methods current study integrates isotopic tracers, hydrogeochemistry, geophysical logs, positive matrix factorization (PMF model), Monte Carlo (MCS) simulation for pollution source apportionment risks associated heavy Nubian Sandstone aquifer (NSSA). Results Discussion resource used drinking purposes (NSSA) is pale meteoric (non-rechargeable aquifer). Silicate weathering, old trapped sea water, reverse ion exchange evaporation, dissolution are dominant mechanisms controlling chemistry. PMF model showed that major ions NSSA originated from four significant sources (anthropogenic activities, minerals, iron-bearing mixing seawater, hydrothermal water). total risk (HI) oral values highlighted non-carcinogenic dangers adults children through exposure. At same time, dermal contact posed a no high children. Most samples had carcinogenic (CR) higher than allowed limits (1.0E-4) like Cadmium, chromium, lead, suggesting effects across all age groups. approach-based concern evaluation assessed 5th % CR (child) 0.00012, 0.0036, 0.0088 Cd, Cr, Pb, respectively, indicating more potential Urgent comprehensive treatment measures imperative mitigate identified area.
