Abstract:

the effects of Cr pollution in the ground water and soil, and absorption and accumulation by the plants, which were nearby an electroplating factory, were studied and analyzed, the results indicated that, the ground water and the soil nearby the electroplating factory are both polluted in different degrees by Cr, the Cr content in the soil is obvious positively related to the Cr(VI) content in the groundwater(R2=0.990 4); Cr content in the plants is significant different in different environments, with the increase of Cr content in soil, Cr content in the plants is also an increasing trend; Conyza canadensis can accumulate Cr, its Bioaccmulation Coefficients of roots reach 0.584 8~0.831 5, its Bioaccumulation Coefficient of root reaches 0.584 8~0.831 5, Bioaccumulation Coefficient of shoot is 0.260 4~0.451 4; Eleusine indica and Rehmannia glutinosa Libosch. have strong abilities to transporting Cr from the root to shoot in plants, their Transfer Coefficients of shoots are respectively up to 1.618 5~2.712 0 and 1.355 6~1.899 1.”
