In general salts which high charge ions (+ and -) dissolve slightly in water. The World Health Organization (WHO) has a slightly lower health guideline of 0.7 mg/L (or PPM) for barium in water. The solubility of barium compounds increases under low-pH conditions, meaning that higher concentrations of dissolved barium are possible in acidic water. No barium was added for the first 2 weeks, which served as a control period; drinking water containing 5 mg barium/L (0.14 mg barium/kg bw/day using reference values of 2 L/day for water consumption and 70 kg for body weight) was administered for the next 4 weeks, and drinking water containing 10 mg barium/L (0.21 mg barium/kg bw/day) was .
