Description:
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 14C-labeled organic chemicals. Uptake rate constants for the chemicals tested occurred in the following order: captan approximately equals phenol > aniline > ethanol approximately equals indole approximately equals trifluralin approximately equals propanil > 1,2,4-trichlorobenzene(TCB) > nitrobenzene approximately equals atrazine > bromacil > simazine > monuron.
