Boron and water: reaction mechanisms, environmental impact and health effects
Seawater contains approximately 4-5 ppm
boron. River water generally contains only 10 ppb. In seaweed 8-15 ppm and in mussels 4-5 ppm (dry mass) of boron was found.
Boron dissolved in water occurs as B(OH)
3 (aq) or B(OH)
4- (aq).
