PBT assessment: overall result

Reference
Name:
Solvent Yellow 124 - boundary comp.
Type of composition:
boundary composition of the substance
State / form:
liquid
Reference substance:
Solvent Yellow 124 - boundary comp.
PBT status:
the substance is not PBT / vPvB
Justification:

The available evidence on degradation, bioaccumulation potential, and toxicity for C.I. Solvent Yellow 124 indicates that the screening criteria for persistence (P) is met, the criteria for bioaccumulation potential (B) is not met, and the screening criteria for toxicity (T) is met. Based on the information described below, the substance is not PBT nor vP/vB.

Persistence assessment:Solvent Yellow 124 was tested for biodegredability. The degradation rate o was <10% after a test duration of 28 days. Based on screening level criteria, the test substance is considered persistent (P).

Bioaccumulation assessment:The predicted log (base 10) of the n-octanol/water partition coefficient for C.I. Solvent Yellow 124 was >6.   The bioaccumulation potential of C.I. Solvent Yellow 124 was assessed by method OECD 305 and the results of this study indicated that the test substance is not bioaccumultive.

Toxicity assessment: The material is classified as Reprotoxic 1B, and STOT RE2 so meets the criteria for T. In addition the long term toxicity testing on aquatic inverterbrates resulted in a NOEC of <0.01mg/L
