title: Excised Barley root uptake of several (14)C labeled organic compounds.
abstract: Many organic pollutants potentially are available for uptake by plants and thus bioaccumulation and food contamination. One method of studying uptake is with excised roots, a technique extensively used with plant nutrients. A similar method was developed and used to evaluate uptake patterns of several (14)C-labeled organic chemicals. Uptake rate constants for the chemicals tested occurred in the following order: captan ≃ phenol > aniline > ethanol ≃ indole ≃ trifluralin ≃ propanil > 1,2,4-trichlorobenzene (TCB) > nitrobenzene ≃ atrazine > bromacil > simazine > monuron.
