Description of key information

A calculated soil adsorption coefficient, log Koc of 1.78 (Koc = 60.3), was taken as representative for 1,2-dichloropropane.

Key value for chemical safety assessment

Additional information

Soil adsorption coefficients (Koc) for 1,2-dichloropropane have been calculated using various equations based on the relationship between Koc and either water solubility or octanol-water partition coefficients. Reported values for Koc range from 46.9 to 299.14. The value calculated using PcKocWIN, a widely accepted quantitative structure activity relationship developed for the U.S. Environmental Protection Agency, was taken as the key parameter (Koc = 60.3; log Koc of 1.78). 1,2-Dichloropropane is not expected to adsorb significantly to organic matter in soil, sediment, or suspended solids in wastewater or surface waters. The low Koc value suggests that 1,2-dichloropropane would be expected to have high mobility in soil.
