Volatilization of Dieldrin from Fallow Soil as Affected by Different Soil Water Regimes¹

ABSTRACT

Dieldrin was surface applied at a rate of 782 g/plot to 3 15.2- by 22.9-m plots [10 ppm based on a 2 x 10⁶ lb soil/acre 15.2 cm (6 inches)]. Immediately after application, 1 of 3 soil water regimes (flooded, moist, nonflooded) was imposed on each plot. An air sampling system was used to measure the atmospheric concentration gradient of dieldrin between 10 and 30 cm above each plot. Calculations based on the aerodynamic method indicated that approximately 18% of the applied dieldrin volatilized from the moist plot in 5 months, whereas only 2 and 7% volatilized from the flooded and nonflooded plots, respectively. Multiple regression analysis indicated that of the climatic variables measured, temperature had the greatest effect on dieldrin volatilization. There was no apparent dieldrin degradation in any of the plots.

Key Words: turbulent transfer • dieldrin degradation
