7.2.1. Predicted No-Effect Concentration A Predicted No-Effect Concentration (PNEC) was not calculated as no ecotoxicological data were submitted and there will be very low potential for aquatic exposure. 7.3. Environmental Risk Assessment A Risk Quotient (RQ = PEC/PNEC) is unable to be quantified as a PEC and PNEC were not calculated. There is no significant aquatic release of the notified polymer anticipated based on the reported use pattern. Moreover, after curing, the majority of the imported quantity of notified polymer will be incorporated into the adhesive matrix and is not expected to be mobile, bioavailable nor readily biodegradable. The notified polymer contains functionality that may slowly degrade over extended periods of time to form potentially persistent and/or bioaccumulative highly halogenated fragments. However, based on the incorporation of the notified polymer into the adhesive matrix and the expected limited environmental exposure and mobility of the articles formed using the notified polymer, the potential release of highly hydrogenated fragments is expected to be limited. On the basis of the assessed use pattern, the notified polymer is not considered to pose an unreasonable short-term risk to the environment. However, due to the potential release of possibly persistent and/or bioaccumulative highly halogenated fragments, the long-term environmental implications are unknown.
