Extended Data Fig. 2: Mass balance at the catchment land.
From: Agricultural pesticide land budget and river discharge to oceans
(a) Time sequence of PAS budget at the catchment surface and root zone (RZ, 0 to 100 cm) expressing losses (blue) and residue (red) as a percent of the cumulative PAS input mass, with an annual input of 0.94 Tg. (b) Contributions to losses from the catchment surface and RZ. (c) Contributions to residue in RZ. Percentages in parentheses refer to the end of the 30-year simulation, while the percent variability is expressed as one standard deviation (68% CI) across all PAS (see tables of the land and river budges of individual PAS distributed in ”Data and code availability”). The light grey shaded area represents the time frame of near-steady state where the relative contributions have an annual rate of change smaller than 5% relative to the previous year.
