PBT assessment
Administrative data
PBT assessment: overall result
- PBT status:
- the substance is not PBT / vPvB
- Justification:
Naphthalene is considered to be easily biodegradable, as demonstrated by most of the great entirety of biodegradation studies under aerobic conditions, one standard MITI(I) screening test even indicating ready biodegradability. There is clear evidence of at least inherent biodegradability with no signs of persistence.
Based on experimental evidence, bioaccumulation of naphthalene is low with reliable BCF values in fish below 500.
Robust NOEC/EC10 values from aquatic long-term tests with naphthalene are greater than 0.1 mg/L, not any being equal or lower than the NOEC cut-off limit of 0.01 µg/L for the T-criterion.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
