Excised Barley Root Uptake of Several 14C Labeled Organic Compounds

摘要

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.
