A comparative study of the relationships between the mobility of alachlor, butylate, and metolachlor in soil and their physicochemical properties



A comparative study of the relationships between the mobility of alachlor, butylate, and metolachlor in soil and their physicochemical properties



Fate of chemicals in the environment Compartmental and multimedia models for predictions: 231-247



These herbicides showed a decreasing order of mobility in columns of various soils as follows: metolachlor > alachlor > butylate. This correlated directly with the water solubilities and inversely with the adsorption coefficients and octanol/water partition coefficients of these compounds. Diffusion of these compounds in soil thin-layers showed the following decreasing order: butylate > alachlor > metolachlor, which correlated directly with the vapor pressures of these compounds.
