Fig. 2From: Degradation and sorption of the herbicides 2,4-D and quizalofop-P-ethyl and their metabolites in soils from railway tracksDegradation of 2,4-D, 2,4-DCP, and 2,4-DCA in soils from railway tracks and a crushed sand. EB: red, MBS: blue, MR: grey, CS: green. Symbols show measured concentrations, lines are kinetic fits (for 2,4-D, only the slow initial phase was fitted, the following data points are linked by straight lines)Back to article page
