title: [About the conception of "aging" for organic contaminants in soil].
abstract: With the increasing time of contacting with soil particles, organic contaminants decreased their bioavailability apparently, i. e., sequestrated in soil, and aging happened. Relevant studies were carried out extensively, but the conception and connotation of "aging" weren't defined clearly, inducing the discrepancy on its understanding. After summarizing the understandings of relevant researchers at home and abroad, and based on our cognition on bioavailability, the conception and meaning of "aging" for organic contaminants in soil were expounded explicitly, with the other conceptions distinguished, which would be helpful to the studies related, and to those of the environmental chemical behaviors and bioremediation of organic contaminants in soil.
