Nonylphenol

Nonylphenol is a toxic industrial chemical used to make detergents and other surfactants. It forms when nonylphenol ethoxylates break down; it can mimic estrogen in wildlife and harms aquatic life, raising concerns for human health [1][2][3].

Where It Comes From

Production/use of nonylphenol ethoxylate surfactants in detergents, textile and paper processing, and industrial cleaning; releases to wastewater and sediments [1][2].

How You Are Exposed

Low levels in drinking water, indoor dust, and some foods; higher exposure from contaminated fish/shellfish and on-the-job contact in cleaning, textiles, or pulp and paper [1][3].

Why It Matters

Highly toxic to aquatic organisms; persists and builds up in sediments; endocrine-disrupting activity seen in animals; human data are limited but hormonal and reproductive effects are a concern [1][2][3].

Who Is at Risk

Industrial and commercial cleaners, textile and paper workers; people near wastewater discharges; frequent consumers of locally caught fish; infants and children [1][2][3].

How to Lower Your Exposure

Choose products labeled NPE-free/nonylphenol-free; follow local fish advisories; use gloves and ventilation for industrial cleaners; wash hands and reduce dust [1][2][3].
