PFAS/2023/06

Last updated: 25 September 2025

This is a paper for discussion. This does not represent the views of the Committee and should not be cited.

192.         Members are invited to consider the following questions: 

i). Are there any specific papers that the subgroup would like to review in more detail? 

ii). Recovery is assessed in a minority of studies. Should the N/LOAEL be based on effects seen at the end of treatment or after the recovery period? 

iii). Liver effects seen in developmental studies are presented for dams and offspring. The N/LOAELs are based on effects in the dam only. Does the subgroup agree with excluding effects seen in offspring, which will be reported in subsequent papers?
