Applicant's summary and conclusion
- Conclusions:
- Results from the soil transport model indicate that the compound tend to move with the water front with little tendency to adsorb to soil.
- Executive summary:
The movement of DOWANOL PM was examined using the behavior assessment model described by Tillotson. The model includes terms for the processes of volatilization, diffusion in air, diffusion and convection in soil, water, reversible adsorption, and first order degradation. Assumptions in the mode include a) the chemical concentration is below the water solubility and b) linear, equilibrium partitioning of the chemical between the air and solid phases of soil. Chloride was included in the evaluation to serve as a benchmark chemical since previous work has shown that it moves with the water front in soils.
To examine the effect of biodegradation on soil migration, biodegradation half-lives of 2, 10 and 30 days, as well as no degradation, were included in the assessment. Effect of biodegradation on the migration of DOWANOL PM through the soil column were observed at time points 240, 480 and 720 hours. After 720 hours, the center of mass of the DOWANOL PM peak was observed at 98.8 cms regardless of the biodegradation half-life. However, the total mass of DOWANOL PM was observed substantially reduced.
Predicted distribution of DOWANOL PM is:
9.41 % to Air
90.58 % to Water
0.1 % to Sediment
0.01 % to Soil
0.0 % to Biota (Fish)
0.0 % to Suspended Solid in WaterBecause of the typically high water solubility and low vapor pressure of the glycol ethers, the unit word model predicts that the components will partition predominately into the water column with little tendency to volatilize, bioconcentrate in aquatic organisms, or adsorb to soil or sediments. Results from the soil transport model indicate that the compound tend to move with the water front with little tendency to adsorb to soil.
