Abstract:
Intact rice roots, ambient air, soil and irrigation water samples were collected from two sites at Baodi and Xinli, Tianjin. The rice roots were separated into nodal roots and lateral roots, which were extracted individually using a three-step sequential extraction procedure to measure the sorbed, strongly sorbed and interior adsorbed fractions. The results show that remarkable difference of PAH contents between the samples from the two sites and relatively higher PAH contents in the lateral roots than those in the nodal roots, around 60% of the total PAHs detected were those absorbed in the root tissues. Specific surface area and lipid content of the roots are main factors influencing PAH contents.
