Figure 2.

Simulation to assess the duration at which the lower 95% confidence interval crosses the critical threshold of 85% degradation (horizontal black line). Critical threshold values are shown in Table S1 (Supplementary Materials). It can be observed that significant degradation occurred relatively more rapidly with increasing concentrations. This effect appeared to stabilize at higher concentrations, resulting in the degradation becoming significant at around 80 days for concentrations above 35.1 mg/L.
