Figure 1.

Time series of averaged residual MCPA concentrations in 10 cm depth intervals for continuous light rain (CLR; A–C) and heavy rain events (HRE; D–F) scenarios. Lines represent the scenario means, and shaded areas mark their 99%-confidence intervals. Blue bars in panels D–F indicate when heavy rain events occurred. Dotted black lines indicate a detection threshold of 3 μg/kg. Insets in panels D–F show details of days 0 to 20. MCPA concentrations below 30 cm were negligible (<3 μg/kg) and are not shown. Note that y-axis scales vary from panel to panel.
