Why is arsenic toxic

Antimony is toxic for similar reasons, but antimonate ions are much larger and antimony tends to form in the 3+ state so antimony's oxides do not imitate phosphorus as well as arsenic does. This is reflected in antimony's oral LD 50 of $\pu{7000 mg/kg}$ which is 200 times that of arsenic's oral LD 50 of $\pu{14.6 mg/kg}$ Arsenic is an element and is a naturally occurring mineral found widely in the environment. Arsenic exists in four common valence states. Arsenic is widely used commercially, a fact that increases the risk of overexposure. Workers may be overexposed occupationally to arsenic. Inorganic arsenic is generally more toxic than organic arsenic

Why is arsenic toxic to humans? - Chemistry Stack Exchang

Arsenic is highly toxic in its inorganic form. Contaminated water used for drinking, food preparation and irrigation of food crops poses the greatest threat to public health from arsenic. Long-term exposure to arsenic from drinking-water and food can cause cancer and skin lesions Arsenic poisoning, or arsenicosis, occurs after the ingestion or inhalation of high levels of arsenic. Arsenic is a type of carcinogen that's gray, silver, or white in color Arsenic is an element that is extremely toxic to human health. Arsenic poisoning or arsenicosis occurs when someone is exposed to high levels of arsenic, typically by unknowingly ingesting it Inorganic arsenic is generally more toxic than organic arsenic. Forms of arsenic that are more rapidly absorbed are more toxic, while those most rapidly eliminated tend to be less toxic The use of arsenic for this purpose of preserving wood has apparently been diminished, as science revealed how toxic it can be (6, 7). Certainly, as you can see, our exposure to arsenic reaches both far and wide. That is exactly why it is important to monitor your body for arsenic toxicity. Symptoms of Arsenic Toxicit

Arsenic is a chemical element with the symbol As and atomic number 33.

The primary use of arsenic is in alloys of lead (for example, in car. On an atomic level arsenic looks a lot like phosphorus, so enzymes that use phosphor can take arsenic by mistake (like taking a metric screw with an imperial nut), and the resulting product won't work because arsenic has different chemical propert.. Arsenic is toxic at high levels because it can interfere with the way cells produce energy. Some researchers have also expressed concern over arsenic levels found in rice Arsenic is a naturally occurring element widely distributed in the earth's crust. In the environment, arsenic is combined with oxygen, chlorine, and sulfur to form inorganic arsenic compounds. Arsenic in animals and plants combines with carbon and hydrogen to form organic arsenic compounds. Inorganic arsenic compounds are mainly used to preserve wood Arsenic is a toxic substance found in some foods, especially rice and rice-based products.
