Accumulation of di-n-butyl phthalate in different genotypes of Brassica Campestris - soil systems

Different genotypes of Brassica Campestris were pot-cultured in paddy soil polluted by di-n-butyl phthalate(DBP), and the distribution of DBP in Brassica Campestris-soil system was studied adopting GC/MS. DBP accumulation of the leaves and roots of different genotypes of Brassica Campestris varied obviously. The contents of DBP in the leaves and roots of Teqing-60 Brassica Campestris and Youqingsijiu Brassica Campestris were all lower, Yashuquannianyoulu Brassica Campestris and Youqing-60 Brassica Campestris were all higher. The contents of DBP in the leaves existed definite positive correlation with the size of leaves areas. The distribution of DBP in different genotypes of Brassica Campestris-soil systems was different obviously. The contents of DBP in Xinxunsiwu Brassica Campestris in leaves and roots and in pot-cultured soil were lower; DBP contents in Teqing-60 Brassica Campestris and Xinxunsijiu Brassica Campestris in leaves and roots were lower, but DBP content in pot-cultured soil was higher; and DBP contents in Youqing-60 Brassica Campestris in leaves and roots were higher, and also higher in pot-cultured soil.
