内容記述 | To compare the uptake and translocation of hydrophobic organic chemicals by plant species, the authors performed uptake experiments with β-1,2,3,4,5,6-hexachlorocyclohexane (β-HCH) and 1,2,3,4,10,10-Hexachloro-6,7-epoxy-1,4,4a,5,6,7,8,8a-octahydro-endo-1,4-exo-5,8-dimethanonaphthalene (dieldrin) using 5 species: Hordeum vulgare, Glycine max, Solanum lycopersicum, Brassica oleracea, and Cucurbita pepo. The present study evaluated uptake ability using root concentration factor (RCF) and translocation ability by transpiration stream concentration factor (TSCF). The RCFs of β-HCH and dieldrin did not differ remarkably among species, except that the RCF of β-HCH in B. oleracea was high. The TSCFs of β-HCH and dieldrin were high in C. pepo, which was not superior in uptake as estimated by RCF. The TSCF of dieldrin in C. pepo was decreased in darkness and was markedly decreased by heating of roots. These results support the hypothesis that transport proteins produced in the root contribute to dieldrin translocation. In contrast, TSCF of β-HCH was not decreased by these treatments. Therefore, translocation of β-HCH might not need the contribution of transport proteins. It is possible that C. pepo has a certain function to transport hydrophobic organic chemicals smoothly in root tissues. | |||||
