Boron salts naturally occur in low concentrations in most unpolluted waterways. The average concentration for boron in surface waters has been reported to range from 0.001 mg/L (LIVINGSTON 1963) to 0.1 mg/L (KOPP and KRONER 1970; SPRAGUE 1972). Concentrations rarely exceed 0.5 mg/L, but have been measured as high as 5.0 mg/L. In some geographical areas such as the American Southwest, boron does occur in concentrations in surface waters used for irrigation that have been shown to be toxic to… CONTINUE READING
