In this study, the accumulation of 4-bromodiphenyl ether (BDE-3) by different parts of a live white radish was investigated. Different cultural media (hydroponics, silica sand, and soil) were used to sustain the radish plant during its uptake and in-plant translocation of BDE-3. The results showed that BDE-3 can be translocated from the roots to the aboveground organs and the accumulated levels of BDE-3 in different parts of the white radish followed the order for the three types of cultivation: fibrous roots > peels > main roots > leaves. The results were analyzed by the aid of the partition-limited model for the plant uptake. The relevant partition coefficients (KOCand Kd) and uptake parameters of BDE-3 with plant components (Kptand Klip) were obtained for analyzing the BDE-3 distribution. The partition-limited model offers a significant insight into the uptakes of BDE-3 by the various components of live white radishes. The types of cultivation affected the total sorption level, translocation factors (TFs), extent to equilibrium (αpt), and root concentration factors (RCFs).4-Bromodiphenyl etherPartition-limited modelPlant uptakeQuasi-equilibrium factorWhite radish[SDGs]SDG3[SDGs]SDG15journal article10.1016/j.envpol.2017.01.0092-s2.0-85011263950https://www2.scopus.com/inward/record.uri?eid=2-s2.0-85011263950&doi=10.1016%2fj.envpol.2017.01.009&partnerID=40&md5=fe68ff5e5f7f37af12d3bab0979ceb18
