Inventory Multi-tiered Assessment and Prioritisation (IMAP)


The National Industrial Chemicals Notification and Assessment Scheme (NICNAS) is assessing the human health and environmental impacts of previously unassessed industrial chemicals listed on the Australian Inventory of Chemical Substances (AICS). NICNAS has implemented an innovative framework, Inventory Multi-tiered Assessment and Prioritisation (IMAP), to accelerate the assessment of these chemicals.

In July 2012, NICNAS started assessing around 3,000 existing chemicals identified as Stage One Chemicals on the AICS using the IMAP framework.
