The effects of two earthworm species (Eisenia foetida and Allolobaphora caliginosa) on the bioavailability of Zn or Pb were studied in three soils (Cinnamon soil, Aquic brown soil and Acid brown soil) spiked with 200 mg kg-1 Zn or 400 mg kg-1 Pb, respectively. The results showed that Eisenia foetida and Allolobaphora caliginosa were tolerant to Zn or Pb. but the growth of earthworms was adversely...
Two degradation metabolites of benzo(a)pyrene(BaP), cis-BP4,5-dihydrodiol and cis-BP7,8-dihydrodiol, were identified using high performance liquid chromatography (HPLC) with standards. Both BaP and the two metabolites were well-known toxic compounds. The effect of a nonionic surfactant-Tween80 (TW80) on the degradation of the above three compounds by Bacillus-07, in aqueous phase, was studied. The...
