PFUnDA

Synonyms: Perfluoroundecanoic Acid

CAS Number: 2058-94-8

Sources of exposure:

Food

Drinking water; fluorochemical manufacturing; treated consumer products

Description:

PFUnDA is a long-chain per- and polyfluoroalkyl substance (PFAS). It may originate from fluorochemical manufacturing or form through the environmental breakdown of fluorinated precursor chemicals. Exposure may occur through contaminated food, particularly fish and seafood, as well as drinking water, household dust, and industrial pollution. PFUnDA is extremely persistent and can accumulate in people, wildlife, and food webs. Available studies raise concerns about possible effects on development, reproduction, the liver, and metabolism, but its health effects have not been characterized as extensively as those of PFOA and PFOS. Because this PFAS is environmentally persistent and may remain mobile or bioaccumulative depending on its structure and exposure setting, the glossary applies a precautionary approach where long-term hazard and exposure information is limited.

Health concerns:

No specific health concerns have been flagged for this chemical.

HOW MILLION MARKER SCORES CHEMICALS

Million Marker's Ingredient Hazard Scoring uses multiple chemical databases and a science-backed scoring system to compute hazard scores for thousands of chemicals found in consumer products and listed on ingredient labels.

We identified key chemicals based on a database compiling dozens of authoritative sources, screening tools, and QSAR models.

Hazard scores within 11 different health categories (carcinogens, endocrine disruptors, reproductive toxicants, developmental toxicants, genotoxicity, neurotoxicity, organ system toxicity, immunotoxicity, respiratory toxicity, skin/eye/respiratory irritants, and ecotoxicity).

They are weighted based on several factors, including strength of evidence for adverse impacts in humans, severity, and potential contamination.
