Abstract
Aging behaviour of polycyclic aromatic hydrocarbons (PAHs) phenanthrene and anthracene in organo-mineral aggregates from black soil were studied under laboratory incubation. Changes in their extractability and aging rate in different fractions of organo-mineral aggregates were determined through extraction by dichloromethane. After incubation for 90 days, the extractability of phenanthrene and anthracene were seen to be decreased about 10% and 30%, respectively. In clay fractions, the aging rate in the first period (from 0 to 15 days) appeared highest, while in the other three fractions, the higher aging rates existed basically in the period from 15 to 28 days.
