Natural Boron Contamination in Mediterranean Groundwater
W ithin the past few decades, the water quality in many of the coastal aquifers along the Mediterranean Sea has rapidly degraded. Overexploitation of the groundwater basins, particularly during the tourist season, has resulted in the lowering of groundwater tables and increasing seawater intrusion into the aquifers. Countries such as Cyprus and Israel have shut down hundreds of wells along the ...
متن کاملBoron removal in seawater RO desalination
In the seawater desalination field, WHO requires the boron concentration in drinking water to be below 0.5 mg/l, and this requirement has affected SWRO process design, because of the difficulty to achieve such low boron concentration. In order to overcome this problem, a new SWRO membrane element, which had higher boron rejecting performance, was developed. This new SWRO membrane element exhibi...
متن کاملBoron Sheets and Boron Nanotubes
Based on an ab initio study, we present a structure model for a broad boron sheet, which is the precursor of boron nanotubes. Furthermore we could show that, in contrast to the armchair types, zigzag boron nanotubes have no surface tension (strain energy). As result, we predict that boron nanotubes will exhibit a chirality dependent stability, something that is unique among all nanotubular mate...
متن کاملAnalytical Determination of Boron in Irrigation Water Using Azomethine-H: Spectrophotometry
Boron level in irrigation water is an important factor for high yield and quality agricultural production. Concentration below 1ppm provides plants with proper development and higher concentration poses toxicity problem. This necessitates for the use of accurate technique for assessment of boron in the irrigation water. Several analytical methods have been used for determination of boron in wat...
متن کاملToxicity evaluation of boron nitride nanospheres and water-soluble boron nitride in Caenorhabditis elegans
Boron nitride (BN) nanomaterials have been increasingly explored for potential biological applications. However, their toxicity remains poorly understood. Using Caenorhabditis elegans as a whole-animal model for toxicity analysis of two representative types of BN nanomaterials - BN nanospheres (BNNSs) and highly water-soluble BN nanomaterial (named BN-800-2) - we found that BNNSs overall toxici...
