Question

What are the exposure-response functions (ERF) of perfluorinated alkyl substances (PFAS) on several health endpoints?

Rationale

Data

ERF of PFAS(-)

Obs	Exposure agent	Response	Exposure	Exposure unit	ER function	Scaling	Threshold	ERF	Description
1	PFAS	PFAS TWI	Maternal exposure via ingestion	ng /kg /wk	TWI	BW	0	4.4	EFSA 2020
2	PFAS	Immunosuppression	Maternal ingested intake	ng /kg /wk	ERS	BW	0	0.0227	Converted from the row above assuming linearity and steady state
3	PFAS	Cholesterol increase	Ingestion	ng /kg /wk	ERS	BW	0	0	EFSA?
4	PFAS	Decreased birth weight	Ingestion	ng /kg /wk	ERS	BW	0	0	EFSA?
5	PFAS	Increased ALT	Ingestion	ng /kg /wk	ERS	BW	0	0	EFSA?
