Formaldehyde is everywhere, but poses dangers to our health

Season 2025 Episode 11 | 5m 39s

The chemical formaldehyde is found just about everywhere, including in composite lumber, plastics, paints and glues used in many homes and offices. This past week, an EPA evaluation said it poses “an unreasonable risk” to human health. A ProPublica investigation found that it causes far more cancer than any other airborne pollutant. John Yang speaks with lead reporter Sharon Lerner for more.
