Abstract
The objective of this study was to conduct a series of batch and miscible-displacement experiments to examine the mobility of atrazine herbicide in stable-manure amended agricultural soil. Agricultural soil with 10% w/w stable-manure amendment were used for the objectives. Laboratory studies showed that the high sorption of atrazine was described by rate-limited, non-linear reversible processes for stable-manure amended agricultural soil. This non-ideal transport behavior was most likely due to the fraction of high organic matter content in soil. Flow interruption tests in the column experiments indicated that the rate-limited desorption of atrazine mainly controlled the non-ideal transport of atrazine. Behavior of atrazine in such soils could have important impacts for risk assessment of atrazine-contaminated soil and should be taken into account in the regulation, management, and remediation of atrazine-contaminated sites.
