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