Description of key information

Tetramethylthiuram disulfide shows potential for adsorption to the soil

Key value for chemical safety assessment

Additional information

The adsorption/desorption potential of tetramethylthiuram disulfide (CAS No. 137-26-8) was investigated in a study. This test was conducted according to OECD Guideline No.106: Adsorption/Desorption using a Batch Equilibrium Method (2000) and EPA’s Pesticide Assessment Guidelines, CFR 40, Subdivision 163-1 (1982) under GLP conditions.14C-thiram was tested in 4 soil types obtaining log Koc values of 3.3 (sandy loam), 4.4 (loamy sand), 3.8 (silt loam) and 4.1 mL/g (loam).

 

Considering this information, it can be concluded that tetramethylthiuram disulfide shows potential for adsorption to the soil.
