Boron: 2. Where is boron found? - GreenFacts

2.3 How does boron react in the environment? Boron is present in the environment in boron-containing compounds called borates.Borates dissolved in water can adsorb onto, and desorb from, the many different surfaces found in rivers and streams. The amount of borate adsorption depends on the water's pH and the concentration of borate in the water. Borates dissolved in water are very stable ...
