Acrylamide is a potential ground‐water contaminant and is a known neurotoxin to man. Thus, information about its fate in soil is desired. The fate of N in acrylamide added to five soils was studied by performing analyses for NH3, NH4+, NO2−, and NO3− after incubation of acrylamide‐treated soils for various times. The results showed that acrylamide‐N is readily hydrolyzed in field‐moist and air‐dried soils under aerobic and waterlogged conditions and that acrylamide‐N is converted to NO2− and NO3− under aerobic conditions. The percentage of acrylamide‐N recovered as inorganic N increased with increasing temperature (10–30°C) and incubation time (2–21 d). After 3 d of incubation at 30°C under aerobic conditions, the percentage of acrylamide‐N recovered as inorganic N ranged from 11% in Clarion soil to 76% in Canisteo soil. The corresponding recovery values after 14 d of incubation were 74% and 94%, respectively. Generally, the results with field‐moist soils were similar to those obtained with air‐dried soils. The recovery of acrylamide‐N after 21 d of incubation under waterlogged conditions at 20°C ranged from 76% in Harps soil to 93% in one sandy (Chelsea) soil. Expressed as percentage of acrylamide‐N added, the NH+‐N produced in Clarion, Fayette, Harps, and Canisteo soils after 7 d of incubation under waterlogged conditions ranged from 18% in Clarion soil to 38% in Canisteo soil. The corresponding vlaues after 21 d of incubation were 81% and 90%, respectively. Significant amounts of NH3 were volatilized from sandy and calcareous soils treated with acrylamide.
