Fecha de publicación: | 2020 | Editor: | Elsevier | Citación: | Science of the Total Environment 704 (2020) 135398 | Resumen: | The differences of PBDE absorption, accumulation, and metabolism in different cultivars of the same crop are rarely explored. This study used C tracing to fully demonstrate the uptake and transformation of soil-borne BDE209 in three rice cultivars, including two indica (HHZ and YD1) and one japonica cultivars (NJ3). Results showed that about 6.9, 17.2, and 17.4% of the applied C-BDE209 were transformed to C-metabolites in soils planted with HHZ, YD1, and NJ3, respectively. The C-BDE209 and its C-metabolites in soil could be absorbed by the rice and gradually transported to its root, stem, leaf, and grain, with the total whole-plant uptake of 8.52, 4.55 and 3.43 nmol for HHZ, YD1, and NJ3, respectively. The cultivar of HHZ had the greatest whole-plant C absorption but the lowest ΣPBDEs residues in its grain, with the ΣPBDEs of 421.8, 454.2 and 967.0 ng g for HHZ, YD1, and NJ3, respectively. BDE-209 accounted for 90%, 31% and 50% of the ΣPBDEs in the grain from HHZ, YD1, and NJ3, respectively. The estimated daily intake (EDI) amounts of ΣPBDEs were 928, 1056, and 2675 ng kg bw d via consuming rice grains from HHZ, YD1, and NJ3, respectively, which were below the safe threshold limits for human consumption. This study proved the different BDE-209 absorption, accumulation and transformation in different rice cultivars, which potentially suggests the need of considering cultivar differences in assessing the dietary risks of PBDEs. | Versión del editor: | http://dx.doi.org/10.1016/j.scitotenv.2019.135398 | URI: | http://hdl.handle.net/10261/216330 | DOI: | 10.1016/j.scitotenv.2019.135398 | Identificadores: | doi: 10.1016/j.scitotenv.2019.135398 issn: 1879-1026 |
