TLDR
In this paper, the authors measured batch and column experiments were performed using two soils collected from the Maresme area near Barcelona, Spain, and measured batch sorption coefficients ranged from 93 to 154, suggesting that it is strongly bound to soil.About:

Fate and transport of glyphosate and aminomethylphosphonic acid in surface waters of agricultural basins.
TL;DR: Glyphosate use in a watershed results in some occurrence in surface water; however, the watersheds most at risk for the offsite transport of glyphosate are those with high application rates, rainfall that results in overland runoff and a flow route that does not include transport through the soil.
Journal ArticleDOI
Adsorption and mobility of glyphosate in different soils under no-till and conventional tillage
TL;DR: In this article, the adsorption of glyphosate in different soils under long-term management (more than 16 years) of no-till (NT) and conventional tillage (CT) was studied.

Mobility of Cr, Pb, Cd, Cu and Zn in a loamy sand soil: a comparative study
Bruna Fonseca,Hugo Figueiredo,Joana Lúcia Lima Correia Rodrigues,A.M. Queiroz,Teresa Tavares +4 more
TL;DR: In this paper, the authors evaluate the scenario of co-contamination of a loamy sand soil by multiple heavy metals, including Cr, Pb, Cd, Cu and Zn.

TL;DR: The transport of glyphosate and its metabolite aminomethylphosphonic acid (AMPA) related to soil erosion at two slope gradients, two rates of pesticide with a formulation of glyphosate (Roundup®) application, and a rain intensity of 1.0 mm min(-1) for 1 h on bare soil in hydraulic flumes was focused on.
Journal ArticleDOI
Meta-analysis of the effects of soil properties, site factors and experimental conditions on solute transport
TL;DR: In this paper, a database of breakthrough curve experiments under steady-state flow conditions was assembled and the authors focused on three indicators of preferential solute transport: namely the 5-arrival time, the holdback factor, and the ratio of piston-flow and average transport velocities.

Mass transfer studies in sorbing porous media. I. Analytical solutions
TL;DR: An analytical solution for the movement of chemicals through a sorbing porous medium with lateral or intra-aggregate diffusion is presented in this paper, where the liquid phase in the porous medium is divided into mobile and immobile regions.
Journal ArticleDOI
Sorption nonideality during organic contaminant transport in porous media
TL;DR: In this paper, the relative importance of these factors is scale-dependent and their relative impact on contaminant transport is evaluated for hydrophobic organic compounds, physical nonequilibrium (i.e., rate-limited mass transfer in aggregated or layered systems) and intraorganic matter diffusion (rate-limited diffusion within the sorbent organic matter matrix) are probably the predominant factors causing nonideality.

Two-Site/Two-Region Models for Pesticide Transport and Degradation: Theoretical Development and Analytical Solutions
TL;DR: In this paper, analytical solutions for two convection-dispersion type transport models useful for studying simultaneous pesticide sorption and degradation were presented for the familiar two-site sorption model in which adsorption-desorption proceeds kinetically on one fraction of the sorption sites and at equilibrium on the remaining sites.

Adsorption, Mobility, and Microbial Degradation of Glyphosate in the Soil
TL;DR: Glyphosate [N-(phosphonomethyl)glycine] was readily bound to kaolinite, illite, and bentonite clay and to charcoal and muck but not to ethyl cellulose as mentioned in this paper.
