摘要: The phytoremediation, with industrial hemp (Cannabis sativa), of a Hawaiian silty clay soil contaminated two polycyclic aromatic hydrocarbons (PAHs), chrysene and benzo[a]pyrene, was studied. Hemp showed very high tolerance to the contaminants. growth rates hemp, compared control, in soils fortified benzo[a]pyrene at concentrations each varying from 25 200 micrograms/g were consistently above 100%. plants grew seed for 45 days PAHs 25, 50, 75 micrograms/g. Controls pots but no plant. levels significantly reduced all (control seeded pots), expect one set concentration chrysene, which may be due uneven spiking. A time course study over 28 done monitor changes microbial count chrysene. Little observed total soil, decreased slightly containing plants. However, those lower than without
