SUMMARY:

This work aimed to propose a simplified methodology to evaluate the decay profile of the total concentration of hydrocarbons in soil samples contaminated with commercial gasoline. Samples from five types of soils were contaminated in vials and analyzed in subsequent periods of 24h using HS-GC-FID. The data obtained were fitted by an exponential model such as y = α e^-βt for which R² values were between 0.94 and 0.98. Total concentration data differ for soil types and indicate matrix-analyte interaction effects. Virgin soil samples were characterized by TG and DRX/FRX.
