Our priority chemicals list identifies the chemicals we believe are most in need of review here in New Zealand.

The chemicals on the priority list make up part of the larger screened chemicals list, which were screened using our FRCaST screening tool.

The chemicals on the priority list are categorised as either Group A or Group B chemicals.

Find out about how we identified and categorised the chemicals on our screened chemical list.

We are working on reassessing chemicals on the priority list.

We will not necessarily work through the priority chemicals list in the order it appears on our website. This is for many reasons. It is a ‘living’ list, and may be changed as new information comes to hand, prompting us to reprioritise our focus on chemicals with higher risk profiles.

Note from the Fluoride Action Network:
The following is the table of the 40 priority chemicals. We have highlighted, with links to more information, the chemicals that contain fluorine or fluoride: Bifenthrin, Cyfluthrin, Cyhalothrin, Flocoumafen, Flumioxazin, Lambda-cyhalothrin, and Trifuluralin. Chloropicrin is used as the “inert” in the fumigant Sulfuryl fluoride. This perfluorinated chemical (PFC) is listed: Ammonium pentadecafluorooctanoate (APFO). It is the PFOA derivative of greatest concern and most wide spread use. One call tell it’s a PFC as it is perfused with fluorine (see more PFCs structures):
