Hotspot and accumulated hotspot analysis for assessment of groundwater quality and pollution indices using GIS in the arid region of Iran.

Because groundwater quality representatives for drinking usage (i.e., Schuler method, Nitrate and Groundwater Quality Index) have been abruptly changing due to extreme events induced by global climate change and over-abstracting, applying an efficient tool for their assessments is vitally important.

Exposure risk assessment, pollution level, and source identification of arsenic in soil: A case study of the Bardsir Plain (southeastern Iran).

In this study, we investigated the total arsenic concentration in the soil and the related human exposure risks in the central part of the Bardsir Plain in southeastern Iran. The results show that the average total arsenic concentration in agricultural soil is 50.26 mg/kg, which is 2.

Visible-infrared spectroscopy and chemical properties of water in mining area.

The present research focuses on investigating the relationship between spectral and chemical characteristics of water samples in Darrehzar mine. In order to reach this aim, the chemical characteristics of water were measured through pH, electrical conductivity (EC) and inductively coupled plasma mass spectrometry (ICP-MS) analysis. Furthermore, the visible near infrared (VNIR) and shortwave infrared (SWIR) spectra of water samples were measured by Analytical Spectral Devices (ASD) FieldSpec spectroradiometer and the relationships between spectral and chemical characteristics of water samples were calculated.
