Summary
• Flume experiment of glyphosate/AMPA transport by 5 size classes of eroded sediment. • Total pesticide mass balance: soil (72%), runoff (8%), total eroded sediments (10%) • Top 2 cm soil retained 68 % of pesticides, facilitating continued overland transport. • Sediments accounted for 95% of overland AMPA transport, but only 39% for glyphosate. • Smallest sediments (75% of total) carried 85% (60%) of sediment AMPA (glyphosate) Glyphosate and its degradation product AMPA, are ecotoxic, recurrent and persistent in agricultural soils, susceptible to overland transport by runoff, and sediment erosion due to their strong sorption affinities. We hypothesize that eroded sediments of different sizes have differing sorbed concentrations and relative contributions to glyphosate and AMPA transport, d
