Priority Existing Chemical assessments

A priority existing chemical (PEC) is an industrial chemical that has been identified as requiring an assessment because there are reasonable grounds for believing that manufacturing, handling, storing, using or disposing of the chemical could be a risk to health and/or the environment.

Following a chemical assessment by NICNAS, there could be changes in circumstances that would later require particular aspects of a chemical to be re-assessed. This process is called secondary notification and assessment.

Most PEC assessments are accompanied by an easy-to-understand fact sheet which summarises key recommendations for a non-scientific audience.
