text: People who are exposed to PFASs through their jobs typically have higher levels of PFASs in their blood than the general population. While the general population is exposed to PFASs through ingested food and water, occupational exposure includes accidental ingestion, inhalation exposure, and skin contact in settings where PFAS become volatile. The severity of PFAS-associated health effects can vary based on the length of exposure, level of exposure, and health status.
