The Guidelines are intended for use as the basis for regulation and standard setting worldwide. The current recommended limit of
arsenic in drinking-water is 10 μg/L

Who is father of toxicology?
Paracelsus
, pictured here, was a 16
th
century physician and is considered to be the “Father of Toxicology.” Toxicology as a distinct scientific discipline is fairly modern; however, knowledge of poisons and poisoning incidents date back to ancient times.
Who is the father of forensic toxicology?
Mathieu Joseph Bonaventure Orfila
(1787–1853), often called the “Father of Toxicology,” was the first great 19th-century exponent of forensic medicine. Orfila worked to make chemical analysis a routine part of forensic medicine, and made studies of asphyxiation, the decomposition of bodies, and exhumation.
What test was developed to detect arsenic and was the first use of toxicology in a jury trial?
Marsh develops a method for testing the presence of arsenic in human tissue. Using zinc and sulfuric acid to create arsine gas, this test is highly sensitive to even small levels of arsenic.
The Marsh Test
, as it was known, was the first use of toxicology in a jury trial.
