Executive Summary
In order to comply with the European Union’s Registration, Evaluation and Authorisation
of Chemicals (REACH) legislation requirements to perform a persistence,
bioaccumulation and toxicity (PBT) assessment on complex petroleum substances, a
systematic review of the persistence and bioaccumulation properties of petroleum
hydrocarbons was conducted. Those substances deemed potentially to meet the
persistence and bioaccumulation criteria were subsequently assessed for toxicity.
Consistent with REACH technical guidance and Annex XIII criteria, petroleum
hydrocarbons were evaluated using the hydrocarbon block method. Measured data and
model predictions were evaluated for representative structures associated with each block
to develop an evidence-based conclusion regarding PBT properties.
The results of this analysis indicate that higher carbon number blocks tend to fulfill the
persistence criterion while lighter carbon number blocks sometimes met the
bioaccumulative criterion. None of the hydrocarbon blocks were found to meet the very
bioaccumulative criterion. Selected hydrocarbon blocks, namely C16-C18 di-naphthenic
hydrocarbons and C16-C22 poly-naphthenic hydrocarbons were found potentially to
fulfill persistence and bioaccumulation criteria. However, these blocks will not fulfill the
toxicity criteria as they are not soluble enough to pose a chronic aquatic hazard and do
not exhibit health hazard classifications. Therefore, this analysis shows that none of the
hydrocarbon blocks that comprise complex petroleum substances meet the vPvB/PBT
criteria. As part of the TC-NES WG on PBTs, two unique hydrocarbons, namely
anthracene and o-terphenyl, were found to present a PBT concern. However, these
individual substances are not expected to be present in petroleum substances in sufficient
quantity to impact PBT decision-making.
