Over three million hectares of salt-affected soils characterized with high salinity and sodicity caused serious land degradation in Songnen Plain, northeast China. Soil salinity–sodicity heterogeneous distribution under microtopography is usually influenced by several environmental factors. The side direction movement of soil water driven by water from depression is the key factor that aggravat...

The adsorption and penetration of intracellular naked vaccinia virus (INV) and extracellular enveloped vaccinia virus (EEV) were examined. The adsorption kinetics of INV and EEV were similar, but INV adsorption was found to be more sensitive to the adsorption environment than EEV. The PFU-to-particle ratio for the two virus particles indicated that EEV was approximately two times as infectious ...

groundwater quality assessment and selection of appropriate methods of zoning depends on the region conditions, and data availability. the correct choice is a key milestone and a major step forward in the management of groundwater resources. the aim of this study was to evaluate the quality of groundwater for drinking and irrigation purposes in the west of marivan city, iran. for this purpose, ...

Bangong Lake is a narrow and long lake in the arid region of plateau northern Tibet. The salinity east different from that west, resulting differences natural environment human living conditions on each side. Watershed hydrochemical analysis spatial statistical can help to understand regional evolution water quality evaluation. In this study, characteristics surface (glacier, river, lake) groun...

Water quality is identically important as quantity in terms of meeting basic human needs. Therefore, evaluating the surface-water and associated hydrochemical characteristics essential for managing water resources arid semi-arid environments. present research was conducted to evaluate predict agricultural purposes across Nile River, Egypt. For that, several irrigation indices (IWQIs) were used,...

Groundwater is a valuable water source for drinking and irrigation purposes in semiarid regions. pollution may affect human health if it not pretreated provided use. This study investigated the hydrochemical characteristics driving groundwater quality potential risks Xinzhou Basin, Shanxi Province, North China. More specifically, we first using descriptive statistical analysis method. We then c...
