Description of key information

According to “ANNEX IX- STANDARD INFORMATION REQUIREMENTS FOR SUBSTANCES MANUFACTURED OR IMPORTED IN QUANTITIES OF 100 TONNES OR MORE , a bioaccumulation study need not be conducted if:

— the substance has a low potential for bioaccumulation (for instance a log Kow ≤ 3) and/or a low potential to cross biological membranes, or — direct and indirect exposure of the aquatic compartment is unlikely.

The estimated Log BCF of S-allyl O-pentyl dithiocarbonate is 1.864 (BCF = 73.06 L/kg wet-wt) This substance has a limited potential to bioaccumulate (based on log Kow used by BCF estimates: 3.33, and predicted bioconcentration factors, log BCF = 1.864 (EPIWIN/BCF Program). The estimated BCF of 73.06 L/kg wet-wt was measured by calculation from EPI SuiteTM v4.1 Program. These values would suggest very low bioaccumulation potential. This is Exposure Assessment Tools and Models made from EPA (Environmental Protection Agency).

Summary Results:

 Log BCF (regression-based estimate): 1.86 (BCF = 73.1 L/kg wet-wt)

 Biotransformation Half-Life (days) : 0.456 (normalized to 10 g fish)

 Log BAF (Arnot-Gobas upper trophic): 2.01 (BAF = 103 L/kg wet-wt)

 

Log Kow (experimental): not available from database

Log Kow used by BCF estimates: 3.33

 

Equation Used to Make BCF estimate:

  Log BCF = 0.6598 log Kow - 0.333 + Correction

 

     Correction(s):                   Value

      No Applicable Correction Factors

 

  Estimated Log BCF = 1.864 (BCF = 73.06 L/kg wet-wt)
