The arsenic eaters of Styria, who were supposedly immunized against the toxic effects of arsenic (As 2 O 3), appeared increasingly in scientific and popular literature in the second half of the 19th century.This Essay starts with a depiction of this phenomenon from a detective novel and questions whether the observations and scientific knowledge at that time can confirm this legend.
ABSTRACTThis essay explores how the enhanced sensitivity of chemical tests sometimes produced unforeseen and puzzling problems in nineteenth-century toxicology. It focuses on the earliest uses of the Marsh test for arsenic and the controversy surrounding “normal arsenic”—that is, the existence of traces of arsenic in healthy human bodies.

Siegel PhD, in Fundamentals of Forensic Science (Third Edition), 2015. Summary. Forensic toxicology is a part of the science of pharmacology, which is concerned with the quantities and effects of various drugs and poisons on.
Arsenic contamination of groundwater is a form of groundwater pollution which is often due to naturally occurring high concentrations of arsenic in deeper levels of groundwater.It is a high-profile problem due to the use of deep tubewells for water supply in the Ganges Delta, causing serious arsenic poisoning to large numbers of people. A 2007 study found that over 137 million people in more.
Arsenic poisoning is a global health problem. Chronic exposure to arsenic has been associated with the development of a wide range of diseases and health problems in humans. Arsenic exposure induces the generation of intracellular reactive oxygen species (ROS), which mediate multiple changes to cell behavior by altering signaling pathways and epigenetic modifications, or cause direct oxidative.
