Tetradecane, 1,1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,11,11,12,12-pentacosafluoro-14-iodo-

This is a highly fluorinated industrial chemical used to make fluoropolymers; it is part of the PFAS family. It is extremely persistent and can transform into long‑chain PFAS that build up in people and the environment, so exposure is a concern [1][2].

Where It Comes From

Made and used in fluorochemical and polymer manufacturing; releases can occur via air emissions, wastewater, and spills. Related PFAS can form from this type of precursor [1][2].

How You Are Exposed

Living or working near PFAS production or processing sites, drinking contaminated water, breathing or ingesting dust, or handling it in labs/industry [1][3][6].

Why It Matters

Long‑chain PFAS are linked to higher cholesterol, liver effects, reduced vaccine response, and developmental impacts; PFOA (a related PFAS) is classified as carcinogenic to humans [1][4][5].

Who Is at Risk

Fluorochemical workers, communities with contaminated groundwater, pregnant people, fetuses, and infants (including those fed breast milk when water is contaminated) [1][3][6].

How to Lower Your Exposure

Test private well water; use certified home filters designed to reduce PFAS (activated carbon or reverse osmosis); follow local fish advisories; reduce indoor dust; and follow workplace controls and PPE guidance [2][3][6].
