PBT assessment: overall result

Reference
Name:
Monomethyltin tris (2-ethylhexyl thioglycolate)
Type of composition:
legal entity composition of the substance
State / form:
liquid
Reference substance:
Composition 1
PBT status:
the substance is not PBT / vPvB
Justification:

Based on results derived from OECD 301F test for biodegradability MMT[EHTG] is not considered persistent [not P]. As MMT[EHTG] can be regarded as “not P, not vP”, further assessments of B/vB and T are not required. Taken together, the BCFBAF and Base-line BCF models are indicative of a low potential for bioaccumulation of MMT[EHTG] [not B]. The toxicity data indicates that MMT[EHTG] is toxic [T]. It can be concluded however that because MMT[EHTG] is not “P”, and not “B” that MMT[EHTG] is not a PBT or vPvB substance. MMT[EHTG] does not meet the “PBT” criteria and is not classified as a PBT chemical. MMT[EHTG] not meet the “vPvB” criteria and is not classified as a vPvB chemical.

Likely routes of exposure:

MMT[EHTG] does not meet the criteria to be classified as either PBT or vPvB and so no emission characterisation is required.
