Information on PFBS

“PFBS is associated with aqueous film-forming foam (foams (AFFFs) and used during chrome
electroplating as a mist suppressant. It has also been found in food contact
materials, dust, and source and finished drinking water. Accordingly, oral intake of water and
food, inhalation, and dermal contact are plausible modes of PFBS exposure, with the oral route
being the primary route of exposure. PFBS has been detected in humans, confirming exposure to
this PFAS; however, the magnitude of human exposure likely depends on factors such as
occupation (e.g., processing and/or manufacture of PFBS or PFBS-containing products and
chrome electroplating) and living conditions (e.g., proximity to locations that make or use
PFBS-containing products and nearby well-water use)…”
