Industrial production; also occurs naturally in crude oil and coal tar, and in smoke from cigarettes and fires [1].

Breathing workplace air; tobacco smoke or secondhand smoke; living near industrial or waste sites; contaminated water; skin contact with products that use pyridine [1][3].

Short-term exposure can cause headache, dizziness, nausea, and irritation; higher exposures can damage liver and kidneys. Cancer data are inadequate; IARC: not classifiable [1][2][3].

Workers in chemical manufacturing or labs; people who smoke or breathe secondhand smoke; residents near contaminated sites [1][3].

Don’t smoke; minimize smoke indoors; follow workplace ventilation and PPE; check local water reports; use certified VOC-removing filters if contamination is found; seek care if symptoms occur [1][3].
