Drinking Water Health Advisory for Boron, May 2008.
naturally-occurring element found in rocks, soil, and water. The concentration of boron in the earth's crust has been estimated to be <10 ppm, but concentrations as high as 100 ppm can be found in boron-rich areas (Woods, 1994). Boron is a polymorphic element that exists in a

Boron in Drinking-water - World Health Organization
Waterborne boron may be adsorbed by soils and sediments. Adsorption–desorption reactions are expected to be the only significant mechanism influencing the fate of boron in water (Rai et al., 1986). The extent of boron adsorption depends on the pH of the water and the concentration of boron in solution.

Boron (B) and water - Lenntech
High boron concentrations in water may be toxic to fish species, regarding concentrations of 10-300 mg/L. For water plants mainly borate is hazardous. Boron is not a dietary requirement for vertebrates. Boric acid is mildly water hazardous, but boron halogens are strongly water hazardous. Boron is averagely mobile and is transformed slowly.

Of the ground water sources, 3.1% had boron concentrations that exceeded the HRL of 1,400 µg/L; the highest observed concentration was approximately 3,300 µg/L. In contrast, none of the surface water sources exceeded the boron HRL of 1,400 µg/L, and the highest concentration in surface water was 345 µg/L. These results 3-3

Boron - Health Professional Fact Sheet
Boron concentrations are about 0.27 mg/L in breast milk and 0.33 mg/L in cow's milk . Water contains boron, but the concentration varies considerably by source . The median boron concentration of drinking water in the United States is 0.031 mg/L . Selected food sources of boron are listed in Table 1.
Boron Concentration - an overview | ScienceDirect Topics
F. Reventos, in Thermal-Hydraulics of Water Cooled Nuclear Reactors, 2017 3.2.3.9 Boron dilution/deboration. Boron dilution is the process where a local decrease in boron concentration in primary system occurs. Deboration is the process where a net loss of boron from primary system occurs, which implies a decrease in average boron concentration.

Boron is a naturally-occurring element found in rocks, soil, and water. The concentration of boron in the earth's crust has been estimated to be <10 ppm, but concentrations as high as 100 ppm can be found in boron-rich areas[6] . Only the latter has a high thermal neutron capture cross section (3832 b). Due to its nuclear characteristics e.g ...

In our study, the median (IQR) concentration of serum boron was 22.0 (17.6–29.7) ng/mL. The boron concentration in this study was lower than those in previous reports. In northern China, the blood boron concentration of people living in areas without boron factories was 74.4 ng/mL in 2003 and 183.1 ng/mL in 2004 (Xing et al., 2008).
