Groundwater chemistry of small tropical islands is influenced by many factors, such as recharge, weathering and seawater intrusion, among others, which interact with each other in a very complex way. In this work, multivariate statistical analysis was used to evaluate the factors controlling the groundwater chemistry of Kapas Island (Malaysia). Principal component analysis (PCA) was applied to ...
Contaminated drainage from metal mines is a serious water-quality problem facing nations that exploit metal mineral resources. Measurements of river hydrochemistry during baseflow are common at mine sites, whilst detailed hydrochemical information regarding stormflow is limited and often confined to a single event. This study investigates the seasonal evolution of stormflow hydrochemistry at an...

Iran's groundwater hydrochemistry has not been well understood. In this study, is evaluated using a rich, ground-trusted data sampled from 9,468 wells distributed across the country in 2011. Twelve quality parameters were analyzed each sample, resulting 113,616 over study period. Examination of anions-cations shows that concentrations sodium, calcium, chloride, and sulphate are higher than acce...
Background & Aims of the Study: Groundwater resources are a crucial component of the ecosystem. Management and cleanup of contamination from groundwater resources requires a long term strategy and a huge amount of investments. Artificial neural networks (ANN) and Geographic Information System (GIS) can be useful in determining management strategies. To protect these valuable resourc...
Interaction of aerosol particles composed of protein and salts with water vapor: hygroscopic growth and microstructural rearrangement E. Mikhailov, S. Vlasenko, R. Niessner, and U.

evaluation of the geochemistry and hydrochemical quality of bam salt dome located in southern iran, was conducted in this study. two composite samples from salt units were collected and analysed by xrd and xrf to determine their mineral and elemental compositions. water samples were also collected from the only spring in the area and analysed for major anions, cations and some toxic elements. t...
Rio da Serra watershed presents well preserved fragments of rain forest at the headwaters and small farms at middle and final stretches. These features allowed the study of fluvial hydrochemistry, under quasi pristine conditions. Sampling stations were established in order to represent the basin, and visited during dry, intermediate and wet periods. Obtained results are: temperature (22.1-28.6 ...
anthropogenic eutrophication conditioned frequent and more pronounced blooms of toxicalgae and cyanobacteria in the fresh and saline aquatic ecosystems all world around. however, bloomingspecies could serve as a possible resource instead of a threat by exploiting them to remediate nutrients. theoptimised use of algae and cyanobacteria may provide the environmental service together with economic...
