Why 19th Century Wallpaper Was Actually A Deadly Weapon #historical #toxins #shorts

In the 19th century, a highly fashionable emerald pigment known as Scheele’s Green took the design world by storm, appearing on everything from elegant dresses to household wallpaper. However, the vibrant dye contained massive amounts of toxic copper arsenic, which turned deadly when exposed to moisture. In damp environments, common mold would feed on the wallpaper and convert the solid arsenic into a highly toxic, odorless gas that unsuspecting families breathed in while they slept. This beautiful nightmare is heavily tied to the death of the exiled French Emperor Napoleon Bonaparte, whose damp residence on Saint Helena was covered in this star-patterned green wallpaper; modern analysis of his hair later revealed shockingly high levels of arsenic, confirming that his interior decor likely cut his final days short.
