Arsenic poisoning. Arsenic poisoning (or arsenicosis) is a medical condition that occurs due to elevated levels of arsenic in the body. [ 4] If arsenic poisoning occurs over a brief period of time, symptoms may include vomiting, abdominal pain, encephalopathy, and watery diarrhea that contains blood. [ 1]
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.
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 tube wells for water supply in the Ganges Delta, causing serious arsenic poisoning to large numbers of people.
[12] [13] However, arsenic poisoning occurs in multicellular life if quantities are larger than needed. Arsenic contamination of groundwater is a problem that affects millions of people across the world. The United States' Environmental Protection Agency states that all forms of arsenic are a serious risk to human health. [14]
In reality, having trace amounts of arsenic in your blood does not necessarily translate to arsenic poisoning. According to the Agency for Toxic Substances and Disease Registry, the estimated ...
In 1858 a batch of sweets in Bradford, England, was accidentally adulterated with poisonous arsenic trioxide. About five pounds (two kilograms) of sweets were sold to the public, leading to around 20 deaths and over 200 people suffering the effects of arsenic poisoning . The adulteration of food had been practised in Britain since before the ...
Infobox references. The arsenate is an ion with the chemical formula AsO3− 4. [ 1] Bonding in arsenate consists of a central arsenic atom, with oxidation state +5, double bonded to one oxygen atom and single bonded to a further three oxygen atoms. [ 2] The four oxygen atoms orient around the arsenic atom in a tetrahedral geometry. [ 2]
Chronic arsenic poisoning is known as arsenicosis. This disorder affects workers in smelters, in populations whose drinking water contains high levels of arsenic (0.3–0.4 ppm), and in patients treated for long periods with arsenic-based pharmaceuticals. Long-term ingestion of arsenic trioxide either in drinking water or as a medical treatment ...
