Potassium-argon analysis by stqwise dissolution provides a way to measure in detail the distribution of argon isotopes and potassium in rock salt. The method can be used for salt that contains only trace amounts of potassium, because the potassium and argon in detrital silicates within the salt are not released during the dissolution. Water may be used as the solvent when relatively large a...

Soil salinity is one of the most critical factors reducing crop yield. SOS signaling is one of the significant pathways that regulate ion homeostasis and it has the important role in mechanism of plant resistance to environmental stresses such as salt stress. Roots are the first organ of plants exposed to salt, so the role of genes involved in this pathway and their relation to salt tolerance w...

the biosorption of hexavelent chromium from saline solutions by posidonia oceanica, a marinebiomass, was studied as a function of ph, initial chromium (vi) and salt (nacl) concentrations in batchsystem. the sorbent exhibited the maximal chromium (vi) uptake at ph 2 regardless of the presence ofincreasing salt concentration. equilibrium uptake increased with chromium (vi) concentration up to 250...

Background: Cardiovascular diseases (CVDs) are the leading cause of premature death in the 21st century. Dietary factors, such as high salt intake, are related to increased risk of CVDs{Akpolat, 2009 #21}. One of the main sources of dietary salt is bread. On the other hand, salt content is a quality indicator of bread. Therefore, this study was conducted to evaluate the salt content in a variet...

     Salt crystallization is one of the most powerful weathering agents that may cause a rapid change in the mechanical properties of stones, and thus limit their durability. Consequently, determining the mechanical properties of stones due to salt crystallization is important for natural building stones used in marine environmental and mild climatic conditions, which expose excessive salt crys...

Lead, cadmium, mercury and arsenic are the most important heavy metals which may cause health risks following consumption of contaminated foods. Table salt is one the mostly used food additive with unique place in food consumption. Although purified table salt is expected to have lower level of contamination, some Iranians still prefer to use rock salt. Use of rock salt for food purposes has be...
