Where It Comes From
Made for industrial use (dye/drug intermediates; lab reagent); releases can occur during manufacturing, processing, or waste handling. [1][3]
How You Are Exposed
Mostly at work by breathing vapors or dust and through skin contact; it can be absorbed through the skin. Nearby communities may be exposed after spills or emissions. [1]
Why It Matters
Can cause methemoglobinemia (reduced blood oxygen), headache, dizziness, bluish skin, and eye/skin irritation; repeated exposure may affect liver and kidneys. IARC: Group 2B (possible carcinogen). [1][2]
Who Is at Risk
Workers in dye, pharmaceutical, or lab settings using p‑anisidine; people with preexisting blood or breathing conditions may be more sensitive; lack of ventilation or protective gear raises risk. [1]
How to Lower Your Exposure
At work, use closed systems and local exhaust, chemical‑resistant gloves, goggles, and protective clothing; avoid skin contact and wash promptly; follow training and exposure limits. In communities, follow spill advisories and avoid contaminated areas. [1][3]
