Stas was born in Leuven and trained initially as a physician. He later switched to chemistry and worked at the École Polytechnique in Paris under the direction of Jean-Baptiste Dumas. Stas and Dumas established the atomic weight of carbon by weighing a sample of the pure material, burning it in pure oxygen, and then weighing the carbon dioxide ...
Toxicology is a scientific discipline, overlapping with biology, chemistry, pharmacology, and medicine, that involves the study of the adverse effects of chemical substances on living organisms [1] and the practice of diagnosing and treating exposures to toxins and toxicants. The relationship between dose and its effects on the exposed organism ...
Hippolyte Visart de Bocarmé (Weltevreden, Java 14 June 1818 – Mons, Belgium 19 July 1851) was a Belgian nobleman and convicted murderer. He poisoned his brother-in-law in order to acquire some urgently needed money. In 1851, the chemist Jean Servais Stas proved that Visart de Bocarmé had used nicotine extracted from tobacco leaves as poison.
The leaf extract was a popular pest control method up to the beginning of the 20th century. In 1851, the Belgian chemist Jean Stas documented the use of tobacco extract as a murder poison. The Belgian count Hippolyte Visart de Bocarmé had poisoned his brother-in-law with tobacco leaf extract in order to acquire some urgently needed money.
Marsh test. The Marsh test is a highly sensitive method in the detection of arsenic, especially useful in the field of forensic toxicology when arsenic was used as a poison. It was developed by the chemist James Marsh and first published in 1836. [1] The method continued to be used, with improvements, in forensic toxicology until the 1970s.

Toxicology testing is commonly conducted during preclinical development for a substance intended for human exposure. Stages of in silico, in vitro and in vivo research are conducted to determine safe exposure doses in model organisms. If necessary, the next phase of research involves human toxicology testing during a first-in-man study.
