Biological Mechanisms for Association with Organic Components of Soil and Sediment

Biological Mechanisms for Association with Organic Components of Soil and Sediment 

These may involve both the original componnd and its metabolites produced by biological reactions. This mechanism has wide implications, and has been most extensively documented in the terrestrial environment. 

Naphth-l-ol is an established fungal metabolite of naphthalene and may play a role in the association of naphthalene with humic material (Burgos et al. 1996). 

i C-labeled metabolites of 9-[i C])-anthracene including 2-hydroxyanthracene-3-carboxylate and phthalate were not extractable with acetone or dichloromethane, but could be recovered after alkaline hydrolysis (Richnow et al. 1998). 

The results of experiments with i C-labeled pyrene added to a pristine forest soil illustrated a number of important issues (Guthrie and Pfaender 1998)
