Scheele's Green, a vibrant green pigment invented by Swedish chemist Carl Wilhelm Scheele in 1778, was widely used in Victorian England. It was found in wallpapers, clothing, toys, and even food decorations. However, this pigment was made using arsenic, a highly toxic substance. Exposure to arsenic can cause a range of health problems. In the short term, it can lead to nausea, vomiting, diarrhea, and abdominal cramps. High doses can cause severe gastrointestinal symptoms, low blood pressure, heart arrhythmias, and even death due to fluid loss and cardiovascular collapse. Long-term exposure to arsenic is linked to various cancers, including skin, lung, and bladder cancer. It can also cause non-cancerous health issues such as hypertension, diabetes, and neurological problems. In Victorian England, many people suffered from these health issues without knowing the cause. The dangers of Scheele's Green became widely recognized after several deaths and illnesses were traced back to it. By the late 19th century, safer dyes were developed, and the use of arsenic-laden pigments declined.
