Based on the maximum [SIGMA] 8PAH concentration measured in any sample of a given type, MOEs calculated for oral exposure in an adult weighing 60 kg and consuming 2 L of water per day were < 10,000 for low- and high-flush samples, after-flush samples (collected 15 min after flushing), and samples taken 2-4 hr after repair (Table 2).
