英文摘要 | This study investigated the uptake of Cs-134 by Lactuca sativa L., Silybum marianum Gaertn., Centaurea cyanus L., Carthamus tinctorius L. from the Asteraceae, and Beta vulgaris L. var. 'Lutiancai' and Beta vulgaris L. var. 'Hongtiancai' from the Chenopodiaceae grown in two widely-distributed soils (a paddy soil and a red soil) in South China. The results showed that the plants growing on the paddy soil had a relatively high yield and low [Cs-134] while those growing on the red soil showed the opposite trend. The accumulation of Cs-134 was dependent on plant species and soil types. For the paddy soil, mean values for [Cs-134] were higher for the species of the Asteraceae (ranging from 165 to 185 Bq g(-1)) than for those of the Chenopodiaceae (less than 140 Bq g(-1)). For the red soil, S. marianum and C. cyanus of the Asteraceae had high average concentrations of Cs-134 ranging from 340 to 400 Bq g(-1) but L. sativa and C. tinctorius from the same family had low concentrations of Cs-134 ranging from 115 to 200 Bq g(-1) on a dry weight basis. B. vulgaris L. var. 'Lutiancai' and Beta vulgaris L. var. 'Hongtiancai' accumulated from 120 to 231 Bq Cs-134 g(-1) of plant shoot. The transfer factor values of Cs-134 for the studied species were in general higher in red soil than in paddy soil except C. tinctorius. All plant species from the Asteraceae family growing on the paddy soil had higher transfer factors than the B. vulgaris species. S. marianum, and C. cyanus growing on the red soil had TFs > 1, being much higher than the B. vulgaris species. The results therefore showed that the plant species from the Asteraceae could accumulate higher concentrations of radiocesium than the Beta vulgaris that has previously been suggested as a candidate for phytoremediation of radiocesium contaminated soils. |
