Hydrogeochemical assessment of Ramsar wetland sites in Gujarat, India using environmetric techniques Mukesh P. Chaudhari, Gh Ali, Mostafa M. Basheir, Ruchi Nair, Divya R. Mishra, Pranav S. Shrivastav Cleaner Water, 2025 Ramsar wetlands are essential ecosystems that play a vital role in supporting biodiversity and maintaining water balance, making them ecologically and hydrologically significant. The study was conducted at four such sites in Gujarat — Khijadia, Nal Sarovar, Thol, and Wadhvana — to determine the variability in water quality, the predominant geochemical processes, and their potential for irrigation and domestic use. Major ions and physicochemical parameters in 12 surface water samples (3 samples from each wetland) were analyzed. Findings demonstrate slightly alkaline waters throughout the locations, with very high EC and TDS in Khijadia and Nal Sarovar due to evaporation and the intrusion of saline waters. In contrast, Thol and Wadhvana demonstrated relatively higher quality, but with locally elevated fluoride levels (>1.5 mg/L). The Thol and Wadhvana were rated good, and Khijadia and Nal Sarovar were rated poor by the Canadian WQI. High salinity hazards in Nal Sarovar and overall suitability in Thol and Wadhvana were demonstrated using irrigation indices (SAR, RSC, MAR, and KR). Piper, Durov, and Gibbs diagrams revealed four facies: Khijadia (Mg-Cl), Nal Sarovar (Na-Cl), Thol (Na-Cl), and Wadhvana (Ca-Mg-Cl). PCA identified three components that accounted for more than 90 % of the total variance, with strong correlations among Na⁺–Cl⁻–Mg²⁺ that are associated with salinity and rock-water interactions, suggesting these are the most significant controls. Elevated Na⁺, Cl⁻, and F⁻ suggest potential health risks for drinking use. In general, Khijadia and Nal Sarovar represent saline systems, whereas Thol and Wadhvana are freshwater wetlands influenced by local hydrology and lithology. These lessons offer guidelines for monitoring and managing wetlands in semi-arid areas to sustain ecological and human health.
Evaluation of adsorption isotherms and kinetics of chloride ion in water using biochar derived from locally available agro-waste Mohd Ishaq, Rc Chhipa, Anupama Sharma, Gh Ali Environmental Research and Technology, 2025 The uses of agricultural byproduct solid wastes to develop low cost sorbents are advantageous and promising for the removal of water contaminants. It serves the purposes of both environmental remediation and appropriate management of agricultural waste generated during agricultural processing. In this study, locally available apricot seed shell and Salix Alba leaves were utilized as agro-waste for the preparation of adsorbents. The biochar was prepared at 300-400oC via pyrolysis and 80 mesh particle sizes were modified by 1N HCl. The unmodified and acid modified local Salix Alba leaves and Apricot seed shell biochar were used to study the adsorption of chloride ion in water, which can damage appliances of industries and also poses health issues at elevated concentration. Adsorption kinetics including pseudo 1st and 2nd order and equilibrium studies including Langmuir and Freundlich isotherm were conducted at pH 7. The adsorption efficiency of modified biochar was much higher than the unmodified biochar due to induce surface positive charge. The Langmuir maximum adsorption of modified Salix Alba leaves sorbent was found to 22.98 mg/g, while modified Apricot seed shell biochar was found to 25.83 mg/g. The experimental data were simulated and applied to fit adsorption isotherm and kinetics models and found a better compliance with Langmuir isotherm model and pseudo 2nd order kinetics model. The RL value and KL value indicated favorable sorption and enhanced sorption affinity. The kinetics also indicated that there is interaction between adsorbate and adsorbent active sites and the result indicated a significant potential of both adsorbents for the removal of chloride ion.
Eco-Friendly Method for the Determination of Lanreotide in Human Plasma Using Ultra-High-Performance Liquid Chromatography-Tandem Mass Spectrometry: Assessment of Greenness using the Analytical Greenness Metric Tool, Analytical Eco-Scale, and Green Analytical Procedure Index Priyanka A. Shah, Primal Sharma, Mallika Sanyal, Gh. Ali, Pranav S. Shrivastav Journal of Analytical Chemistry, 2025 Abstract An efficient, sensitive, and eco-friendly ultra-high-performance liquid chromatography-tandem mass spectrometry method was developed to determine lanreotide in human plasma. The extraction of lanreotide and lanreotide-d8 from 300 µL human plasma using an Oasis® HLB 96-well µElution Plate yielded a consistent mean percentage of recoveries of 73.2%. The extracts were analyzed on a Peptide HSS T3 column under gradient-based separation conditions with a flow rate of 0.3 mL/min. The mobile phase consisted of 0.1% formic acid in water and acetonitrile. The detection was performed using a tandem mass spectrometer in positive ionization mode. Multiple reaction monitoring was used to analyze doubly charged precursor ions for lanreotide (m/z 548.8 → 170.0) and lanreotide-d8 (m/z 552.6 → 170.1). The method demonstrated good linearity over a concentration range of 0.1–20 ng/mL with a correlation coefficient greater than 0.997. The intra- and inter-batch precision (coefficient of variation) ranged from 1.5 to 7.4%, and the accuracy was 94.3–103.6%. The lanreotide-d8-normalized matrix factors ranged from 0.976 to 1.021. The analyte demonstrated sufficient stability under different analytical conditions. Further, the greenness of the developed method was assessed by the Analytical Greenness metric tool, Analytical Eco-Scale, and Green Analytical Procedure Index.
Temporal changes in water quality in Leh Ladakh region: Impact of urbanization Gh Ali, Mukesh Chaudharı, Priyanka Shah, Pranav Shrivastav Environmental Research and Technology, 2024 Water is a valuable and limited resource in semi-arid regions like Ladakh. Effective management and conservation of water are crucial to prevent negative consequences on the area's quality of life. Since becoming a Union territory, Leh, a district of Ladakh, has undergone rapid urbanization due to its administrative status, air service facilities, tourism, and increasing population. However, this urbanization and tourism boom have resulted in a higher demand for water and a decline in its quality. Glacial-fed water is the primary source for drinking and agriculture in Ladakh. As Ladakh has become a popular tourist destination, the distribution and quality of water have been negatively affected. Construction of hotels and guest houses on agricultural lands, could further harm Ladakh's fragile ecological environment. Due to the challenging terrain and harsh conditions, there has been limited research on water quality in the region andare confined to the Leh district only. Despite lack of comprehensive information, this review aims to address three important questions: the hydrochemistry of water resources, the impact of urbanization on water quality, and the existing research gap in hydrochemistry in significant areas and water resources. The objective is to establish fundamental data for future research and contribute to a better understanding of water resources in the region.
Assessment of heavy metal contamination in the groundwater of Gujarat, India using the Heavy Metal Pollution Index Mukesh Chaudharı, Ritu Chotalıya, Gh Ali, Ajay Pandya, Pranav Shrivastav Environmental Research and Technology, 2024 Groundwater serves as a vital water source for a significant population in the Gujarat region of India. However, substantial contamination from heavy metals, pose a serious threat to human health through various pathways, including drinking water. The rapid industrial and agricultural growth in recent years has exacerbated heavy metal pollution in the state. This study focuses on assessing the heavy metal contamination in the groundwater of Gujarat using the Heavy Metal Pollution Index (HPI). The research covers the entire state, considering its diverse physical, climatic, topographical, and geographical conditions. The HPI scores obtained from individual studies highlight the extent of pollution caused by heavy metals. The overall findings underscore the severe problem of heavy metal contamination in Gujarat's groundwater and the associated health risks. Various other pollution indicators, including the Heavy Metal Evaluation Index, Degree of Contamination, Metal Index, and Water Pollution Index are discussed as tools to assess contamination levels. These indices compare concentrations of different heavy metals with established limits to determine the pollution level. The goal is to provide valuable insights for investors and policymakers in formulating strategies to manage and reduce heavy metal contamination across the state. Additionally, the paper explores effective, environmentally friendly, and economically viable treatment techniques to remove heavy metals from aquatic systems, safeguarding the environment. By employing pollution indicators and remedial actions, this study aims to guide efforts in mitigating the impact of heavy metal contamination in the groundwater of Gujarat.
Exploring the Adsorption Efficiency of Local Apricot Seed Shell as a Sustainable Sorbent for Nitrate Ion Mohd Ishaq, R. C. Chhipa, Anupama Sharma, Gh. Ali, Riyaz-ul Hussain Nature Environment and Pollution Technology, 2024 Locally available apricot seed shell as agro-waste was used for the preparation of adsorbents. The biochar was prepared at 370°C via pyrolysis and 80 mesh particle sizes were modified by 1N HCl. Nitrate adsorption and effect of co-ions from aqueous solution were studied under batch model using apricot seed shell powder (ASSP), apricot seed shell biochar (ASSB), and activated apricot seed shell biochar (AASSB). FTIR and pHPZC measurements were used to characterize the adsorbents. Based on the experimental findings, the optimum conditions follow pH 2, 0.3g dosage, initial concentration of 50 mg.L-1, and contact time of 90 min. The three forms of adsorbent exhibited good adsorption for nitrate. However, the maximum percentage removal of nitrate ions from the aqueous solution followed the order AASSB>ASSB>ASSP. The adsorption kinetic of nitrate ion was best fitted by pseudo 2nd order, and the parameters of adsorption isotherms elucidated favorable and improved sorption. This agro-waste could be used to develop sustainable adsorbents in water and wastewater treatment methods and has great potential to replace commercially available sorbents.
