Metribuzine has been used extensively for controlling wide range of broadleaf weeds and grasses, which can lead to severe contamination of soil and groundwater. Wildfires are an important process in environment, which can be severe for many areas and could have a significant impact on the properties of the soil. The objective of this study was to investigate the effect of wildfires for the fate and transport of atrazine for agricultural soil. Miscible displacement experiments were used for the objectives. Results showed that the average distribution coefficient (Kd) obtained from metribuzine was 0.28 and 0.13 L/Kg for soils prior to and after wildfire, respectively. Results indicate that organic matter content of soil has most likely played major role on sorption of metribuzine and exhibited rate-limited sorption-desorption. In addition, sorption of metribuzine onto soil after wildfire was significantly lower which could lead to more contamination risk of groundwater resources. The results from the present study would also help in designing of effective herbicide management strategies for contaminated sites.
