groundwater is the most widely distributed resource of the earth and groundwater quality evolves rapidly as it passes through the subsurface pathways within the unsaturated zone. increasing urbanization and anthropogenic activities have added to the problem of deficient amount of good quality groundwater. the study area is an industrial hub for textile sector. textile production, particularly d...

batiaghata upazila, khulna district in south-west coastal region of bangladesh is the mostly saline affected area, where agriculture activities are mainly dependent on rainfall. 23 water samples from surface water and shallow tube well (stw) were collected in the monsoon season and analyzed for physico-chemical properties to classify them according to salinity hazard. electrical conductivity (e...

The hydrogeochemical characteristics of groundwater are an important element in the study spatial and temporal variation resources, which is crucial to water resources utilization, ecological environmental protection, human development. Water samples were collected at eight observation Nandong Karst System (NKWS) sites each month 2019, main ions isotopes examined. hydrogeochemistry its differen...

Hydrochemical assessment of the freshwater lakes provides important insights into sources dissolved ions, geochemical processes, and anthropogenic activities taking place in environment. This study focuses on hydrochemistry water quality Kupinde Lake, Karnali Province, Nepal. Surface samples were collected from 24 different locations lake October 2021 analyzed for 18 physico-chemical parameters...

dft calculations were used to investigate adsorptionof  f-, cl-, li+ and na+ ions on the exterior surface of mg12o12 nanocage in the gas phase and water media. the most favorite position for adsorption of the studied anions and cations are atop of mg and o atoms of mg12o12, respectively. the strongest interaction is obtained when fluoride is located atop of mg atom with the adsorption energy of...

Ambient aerosol samples were collected over the tropical northern Atlantic Ocean during the month of April 1996 onboard the R/V Seward Johnson. Dichotomous high-volume collector samples were analyzed for ferrous iron immediately after collection, while trace metals, anions, and cations were determined upon return to the laboratory. Data are analyzed with the aid of enrichment factor, principal ...
