Detecting Poisons: From Ancient Times to Modern Labs

Detecting poisons has a long history, from ancient trial-and-error to modern analytical chemistry.
Early methods relied on observation and taste, often with deadly risks.
The Marsh test, developed in the 19th century, detected arsenic with chemical precision.
Modern labs use chromatography and mass spectrometry, identifying toxins at tiny concentrations.
Toxicology detects drugs, heavy metals, and plant or animal poisons, saving lives and solving crimes.
Blood, urine, and tissue samples reveal hidden chemicals, even long after exposure.
Environmental samples are tested, tracking pollutants and accidental poisonings.
Forensic chemistry links poison to perpetrators, providing crucial evidence in court.
Advances in sensitivity now detect substances at parts per billion, far beyond ancient methods.
At its core, poison detection transforms invisible danger into actionable knowledge, protecting health and justice.
