The results of this study reveal a strong linear correlation (R(2) = 0.95) between the rejections of boron and N-nitrosodimethylamine (NDMA) by six different reverse osmosis (RO) membranes, suggesting that boron can be used as a surrogate for NDMA rejection. This proposal is based on the premise that the rejection of both boric acid and NDMA is governed by steric hindrance and that they have si...

By screening a bacterial population from the soil in Tokyo, Japan, we isolated a boron-tolerant bacterium, strain BTM4c. Strain BTM4c grew under the boron excess conditions with 100 mM boric acid, which is generally toxic to bacteria. Molecular phylogenetic, chemotaxonomic, and physiological data showed that the strain belongs to the genus Rhodococcus, and is to be identified as Rhodococcus bai...

The influence of boric acid, a boron carrier, on Ehrlich ascites carcinoma (EAC) cell-bearing mice was investigated in view of its importance in the boron neutron capture therapy and the influence of boron on proliferation and progression of cancer cells mediated by proteoglycans and collagen. The present study included the evaluation of boric acid for the effects on total count and viability o...

Chemical oxo-preceipitation (COP) process that combined the oxidant treatment and precipitation using metal salts was developed for boron containing water disposal under relatively milder conditions (room temperature, pH 10) than a precipitation process. Among the selected boron compounds in 1000 mg-B L, including boric acid (H3BO3), metaborate (NaBO2), borax (Na2B4O7) and perborate (NaBO3), th...

In Germany the addition of the trace element boron as boric acid or borax to food supplements was not permitted up to now. However, this situation could soon change since the laws in the EU Member States are to be approximated and its addition is permitted in other European countries. If this happens, boron could also go on the market in Germany as an ingredient in food supplements. Against thi...

It has been stated and is generally accepted that the isotopes whetlher stable or radioactive behave relative to biological functions as do the commonly occurring forms. It appears to have been assumed that they will function in all phases in the physiology of a green plant in the same way. However, lethal effects (7) and other effects (1) on the plants have been reported but appear to be assoc...

microcerotermes diversus silvestri is the most economically destructive termite in structures in ahvaz (iran), and it consumes almost anything containing cellulose. this species lives in subterranean nests and gains access to buildings and vegetation by constructing underground galleries. because of their insecticidal activity, boron compounds may be beneficial for treating soil to create insec...
