As species in the liquid (top) and gas phases (bottom) of the satellites to the sewage sludge digester (plant #14). Satellites 0a and b (controls) contained no additional As, satellites 1a and b contained 30 µM (2.25 mg L−1) of additional As, and satellites 2a and b 60 mM (4.5 mg L−1) of additional As. As was added as NaAsO2. Concentrations of As species in the liquid phase are given as ppb
