Prioritising chemicals for reassessment

We identify and prioritise the chemicals we believe are most in need of review here in New Zealand.

We prioritise the chemicals to be reassessed where we believe there is a risk to human health and the environment. There may be new or emerging information about a chemical.

We use a screening tool, called FRCaST, that evaluates chemicals' potential risks to human health and the environment. We have screened hundreds of chemicals using the tool, and we continue to assess and screen chemicals. The tool is in line with internationally accepted practice.

From the chemicals we screen, we decide which ones to add to the Priority Chemicals List. It is constantly changing and being updated as new information becomes available.

FRCaST screening tool

We gathered information about chemicals from New Zealand, and from our counterpart agencies in Europe, Norway, Canada, Australia and the United States.

We developed a screening tool to evaluate the chemicals' potential risk to human health and to the environment. This tool was peer reviewed by two international regulatory bodies – the National Industrial Chemicals Notification and Assessment Scheme (NICNAS) in Australia and Environment Canada.
