PBT assessment: overall result

PBT status:
the substance is PBT / vPvB
Likely routes of exposure:

Environment:

As the substance is not volatile and poorly water soluble distribution to soil, sediment and sludge is expected if released to environment.

For industrial uses it can be assumed that the first receiving compartment of the substance is freshwater after passing wastewater treatment systems where adsorption to sludge and elimination is expected. Risk management measures are applied. However, the substance is used as stabiliser for polymers for following applications: coatings, plastics, polyurethanes and adhesives. The concentrations in the corresponding end use applications are very low (< 5 %) and emissions to the different environmental compartments from these end uses are negligible as the substance is included in a matrix.

Human exposure:

In the workplace the body may come into contact with the compound. The substance may possibly enter the body by inhalation, by contacting and passingthrough the skin (dermal route), or in rare cases by swallowing (ingestion). For professional and consumer use, the majority of applications contain the substance at concentrations of < 5 %. Since the substance is predominantly included in a matrix in minimal proportions the exposure can be neglected. Provided the worker handles pure substance, masterbatches or formulations with substantial proportions of the substance appropriate risk reduction measures have to be taken into account. By implementation of the RMMs as well as following the recommendation for the duration of activities displayed in the individual exposure scenarios, the worker is not at risk.
