Boron in Steel Part Two : Total Materia Article

Boron has a high neutron absorption capability.For this reason,it is added to certain types of stainless steel for use in the nuclear industry.Levels of 4% boron or more have been used,but the lack of hot ductility and weldability mean that boron contents of 0.5 to 1.0% are more common for neutron absorption application.Boron in Drinking-water - World Health OrganizationThe natural borate content of groundwater and surface water is usually small.The borate content of surface water can be significantly increased as a result of wastewater discharges,because borate compounds are ingredients of domestic washing agents (ISO,1990).Naturally occurring boron is present in groundwater primarily as a result of Boron - Health Professional Fact SheetThe amount of boron in plant foods depends somewhat on the boron content of the soil and water where they were grown [7,21].Areas of the world with limited boron in the soil include Brazil,Japan,and most of the United States,mainly because of high levels of rainfall,which leaches boron out of the soil [
