摘要

Erosive soils showed a higher loss of sediment material and the medium-soluble propiconazole compared to soil with higher aggregate stability, suggesting that the transport of propiconazole from agricultural fields is related to the detachment of soil particles. Climatic conditions resulting in event-based runoff periods shortly after application of pesticides are of great importance for the transport of propiconazole in association with particulate organic carbon. Suspended sediments have a finer size, with higher content of organic carbon and larger sorption capacity for propiconazole compared to the original soil. The intensity of the flow influences the erosive loss as well as the size distribution and the pesticide sorption capacity of the sediments. The amount of propiconazole attached to suspended sediment will probably decrease when the concentration of suspended sediment is diluted in river and streams. The efficiency of the suspended sediments to carry propiconazole will depend on the amount and composition of the sediment material as well as desorption kinetics.
