Assimilation and Metabolism of Polycyclic Aromatic Hydrocarbons by Vegetation: An Approach to This Controversial Issue and Suggestions for Future Research

摘要

Anthracene (ANTH), smaller and more water-soluble, was assimilated and translocated in bean plants more readily than benzanthracene (BaA), but ANTH was much more readily transformed than BaA. Both ANTH and BaA were translocated, however, 79% of the extractable sup 14 C compounds were found in stems and leaves were water-soluble metabolites produced in the roots. Bean plants assimilated and translocated much more readily from nutrient solution than from soil. 24 refs., 5 figs., 3 tabs. (ERA citation 11:001444)
