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 ]
This unstable allotrope, being molecular, is the most volatile, least dense, and most toxic. Solid yellow arsenic is produced by rapid cooling of arsenic vapor, As 4. It is rapidly transformed into grey arsenic by light. The yellow form has a density of 1.97 g/cm 3. [23] Black arsenic is similar in structure to black phosphorus. [23]
The first breakthrough in the detection of arsenic poisoning was in 1775 when Carl Wilhelm Scheele discovered a way to change arsenic trioxide to garlic-smelling arsine gas (AsH 3), by treating it with nitric acid (HNO 3) and combining it with zinc. [3] As 2 O 3 + 6 Zn + 12 HNO 3 → 2 AsH 3 + 6 Zn(NO 3) 2 + 3 H 2 O
Bottom left: Black arsenic, orthorhombic structure. Right: Yellow arsenic, tetrahedral configuration. [1] Arsenic in the solid state can be found as gray, black, or yellow allotropes. These various forms feature diverse structural motifs, with yellow arsenic enabling the widest range of reactivity.
Nearly 10,000 cases of apple juice have been recalled at Walmart for containing elevated levels of arsenic. Refresco Beverages issued the voluntary recall on August 15, but the FDA recently ...
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 ...
Inorganic arsenic, the type of arsenic involved in Walmart apple juice recall, is a toxic heavy metal. It is more toxic than organic arsenic and is a known carcinogen (meaning it can cause cancer ...
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 ...
