Applicant's summary and conclusion

Validity criteria fulfilled:
not applicable
Conclusions:
The calculated BCF of acetylene was 3 based on the log Kow ov 0.37.
Executive summary:

BCFBAF v3.00 (USEPA 2008) calculates a BCF of 3 for acetylene based on the log Kow ov 0.37. This method is considered adquate for assessment
