Questions & Answers

Q: How does arsenic poisoning affect the body, and why was it a popular poison in history?

Arsenic, when ingested, is absorbed through the small intestine and substitutes for phosphate in necessary enzyme systems, causing various symptoms like paralysis and eventually death. It was popular due to its subtle and hard-to-detect nature.

Q: What makes polonium-210 a deadly poison, and how was it used in a notorious assassination case?

Polonium-210 emits alpha radiation internally, damaging DNA and causing cell death. In the assassination of Alexander Litvinenko, it was cleverly used in tea, with unique energy traits aiding in its identification.
