TL;DR: The patterns of the loads at the field and watershed scales suggested that a major part of the herbicides leaving the fields reinfiltrated to the ground water by seepage through the ditches, and was there degraded or adsorbed.

TL;DR: A comprehensive review of quantitative structure-activity relationships (QSAR) allowing the prediction of the fate of organic compounds in the environment from their molecular properties was done, and the combination of descriptors belonging to different categories led to improve QSAR performances.

TL;DR: In this article, the authors analyzed a dataset of 18 rainfall events including runoff and erosion data from fields of approximately 1200 m2 and 3200 m2 consisting of vineyards with two contrasting weeding practices, either superficial tillage or no-tillage with chemical weeding, from the outlet of a 0.91 km2 catchment that was 70% vineyard.

TL;DR: In this paper, the authors monitored runoff discharge and concentrations of the two soil applied herbicides diuron [3-(3,4-dichlorphenyl)-1,1-dimethylureal and simazine [6-chloro-N 2,N 4 -diethyl-1,3,5-triazine-2,4diamine] from two field sites-one tilled and one no-till-cropped with grapevine (Vitis vinifera L.; Cinsault and Aramon, respectively).

TL;DR: In this article, water balance variables were monitored in a farmed Mediterranean catchment characterized by a dense ditch network to allow for the separate estimation of the diffuse and concentrated recharge terms during flood events.
