Toxic Pigments in History: A Hazardous Legacy
- In 1898, Marie and Pierre Curie discovered radium, a glowing green element with restorative properties that was added to various products like toothpaste, medicine, water, and food. However, its harmful radioactive effects were later realized, leading to its decline in usage due to health risks.
- Lead white pigment, used since Ancient Greek times, was made from lead and caused lead poisoning in artists who used it for paint due to toxic dust exposure. Despite its toxicity, it was widely used for its unique qualities until being banned in the 1970s.
- Synthetic green pigments like Scheele's Green and Paris Green, made from cupric hydrogen arsenic, were vibrant but highly toxic, leading to arsenic poisoning in fabric workers and individuals wearing green clothing. The toxicity of these greens was not widely known until the 19th century, and they were later repurposed as insecticides due to their dangerous effects.
