Understanding PPB

What is PPB?

Parts per billion (PPB) represents the mass ratio of solute to solution multiplied by 10⁹:

PPB = (mass of solute / mass of solution) × 10⁹

1 PPB = 1 ng/mL (for dilute aqueous solutions)

Applications

PPB is used for:

  • Trace contaminant analysis
  • Ultrapure water testing
  • Pharmaceutical analysis
  • Environmental monitoring

Conversions

Common conversion factors:

  • 1 PPB = 0.001 PPM
  • 1 PPB = 0.0000001%
  • 1 ng/mL = 1 PPB (in water)
  • 1000 PPB = 1 PPM

Practical Examples

Typical PPB values:

  • Heavy metals in water: 1-10 PPB
  • Pesticide residues: 0.1-100 PPB
  • Trace elements in blood: 1-1000 PPB
  • Air pollutants: 0.1-1000 PPB
