A natural element of the earth's crust, which enters water supplies either through natural deposition or agricultural and industrial pollution. It is said to be carcinogenic and to be harmful to the skin. and circulatory system.
An element used in wood preservatives and pesticides.
Arsenic is a naturally occurring element which, in its pure form, is a silver-grey crystalline solid. In the environment it is usually combined with other elements in a variety of organic and inorganic forms.
An N-type dopant often used to form the buried layer in a bipolar structure. Also used as an implant source in both bipolar and MOS processing. This element has both metallic and non-metallic properties and hence is frequently referred to as a metalloid. Because of its metalloid properties arsenic can be in compounds both in the anionic and the cationic form. Arsenic is extremely poisonous to human beings and to other living beings.
Steel-grey brittle chemical element found in nature in the form of sulfide.
a chemical element often associated with gold deposits
A metalloid occurring naturally in the earth's crust and fossil fuels. It is used in the production of glass, enamels, ceramics, oil, cloth, linoleum, electrical semiconductors, pigments, fireworks, pesticides, fungicides, veterinary pharmaceuticals, and wood preservatives. It is a known human carcinogen, and bioaccumulates to toxic levels.
Sources include natural deposits, use as a pesticidal agent, and from phosphate fertilizers containing arsenic. Measured in mg/L or ppm. The MCL for arsenic is 0.05 mg/L or ppm.
A natural element of the earth's crust, arsenic enters water supplies either through natural deposition or agricultural and industrial pollution. According to the Environmental Protection Agency (EPA), Office of Ground Water and Drinking Water, health effects of arsenic include skin damage, circulatory system problems and an increased risk of various cancers.
Arsenic in its pure form is a deadly poison. However, when used to color glass, it chemically bonds with the glass very tightly, and poses no risk to the wearer at all. A.R.T. Precious & Collectible Jewelry
(refer also Heavy Metals) Wood preservative, Poison. Lethal dose can be as low as 70mg. Chromium is one of a group of chemicals that cannot be added during manufacture if furniture is to be awarded a Good Environmental Choice Australia Ecolabel. IARC caterories it as a Group 1 Carcinogen ie carcinogenic to humans.
a very poisonous metallic element that has three allotropic forms; arsenic and arsenic compounds are used as herbicides and insecticides and various alloys; found in arsenopyrite and orpiment and realgar
a white powdered poisonous trioxide of arsenic; used in manufacturing glass and as a pesticide and weed killer
Arsenic is a basic chemical element, (symbol: As), which can combine with other elements to form various compounds. It appears as the 33rd element on the Periodic Table of the Elements. Arsenic is classified as a "metalloid" element, which means that it has some of the characteristics of both metal and non-metal elements. In its pure elemental form, arsenic is a steel grey, very brittle, crystalline solid. However, arsenic is usually found in nature combined with other elements in the form of mineral compounds, of which, arsenopyrite (FeAsS) is the most common. Arsenic tarnishes easily when exposed to air, and when heated, is rapidly oxidized to form arsenic trioxide (As).
Arsenic is a chemical that occurs naturally and can also be made in industry. Too much arsenic in your drinking water can lead to serious health effects, such as depression and loss of energy. Arsenic is also toxic to your nervous system.
In early modern usage, the term arsenic refers to what we call white arsenic or arsenic trioxide.
Arsenic is a steel grey, brittle metallic element that is found naturally in rocks and soil. Some of its compounds are poisonous and are used as agricultural insecticides and poisons. Arsenic can bioaccumulate in plants and animals.
A solid, poisonous element that is commonly metallic steel-gray, crystalline and brittle, used as an alloy, especially in lead shot and in electrical circuits
The MCL for arsenic is 0.05 mg/L. Arsenic is highly toxic and its prevalence is due to the natural occurrence of this metal and past use of arsenic in pesticides. Arsenic poisoning typically makes people feel tired and depressed and this poisoning is also associated with weight loss, nausea, hair loss, and marked by white lines across your toenails and fingernails. For freshwater the concentration should be less than 0.05 mg/L.
Naturally present at trace levels in a very few groundwater sources. Arsenic is toxic and when present it is removed by specialist water treatment processes. 50 µg/l
A poisonous chemical used to kill weeds and pests. Also used in cancer therapy.
A metal widely distributed in nature and found mostly in water. Industrial contamination is the primary source of airborne arsenic. Active smelters may be a source of high exposure to arsenic fumes and dust. The manufacture of pesticides and other agricultural products is the major source of occupational exposure. Arsenic has been associated with skin cancer, lung cancer, peripheral vascular disease and liver injury. Reproductive effects have been noted in animals.()
A naturally occurring element in the environment. Arsenic in drinking water commonly comes from natural sources in the ground, but some can come from industrial pollution. At high concentrations it can cause cancer.
Arsenic is a steel-grey metallic element that is found naturally in rocks and soil. When it combines with other elements, it can become poisonous, which makes it useful as an agricultural insecticide and poison. Arsenic can bioaccumulate in plants and animals.
Most exposures to the heavy metal arsenic come from wood that is pressure-treated with Chromated Copper Arsenate (CCA), which is found in playgrounds, fences, decks and other constructions. (Manufacturers of CCA wood stopped producing in at the end of 2003, although stores can still sell the wood until the stockpiles are gone). Arsenic is a carcinogen and has been shown to cause lung, skin, bladder, liver, kidney and prostate cancer. Arsenic can also cause blood disorders, cardiovascular diseases, and is a known hormone disruptor that affects metabolism and immune function.
A chemical element typically used as an N-type dopant in various doping, deposition, and ion implant processes.
a highly poisonous metallic element
This poison forms a very tight, chemical bond when it is used to color glass (or to remove unwanted color from glass) which makes it completely safe to wear.
The recommended maximum level is less than 0.010 mg/L. Arsenic in water occurs naturally as well as from industrial activities. Excessive ingestion of arsenic may cause severe poisoning.
atomic symbol, As, arsenic is the 33rd element in the periodic table ( atomic number 33) with an atomic weight of 74.9. Arsenic is a group V element making it a donor in silicon, i.e., makes silicon N-type. Arsenic has the same atomic diameter as silicon and so introduces very little strain into a silicon crystal lattice. Arsenic has a relatively low diffusivity and is widely used to create shallow doped junctions such as source/drains. Arsenic is toxic and carcinogenic.
Arsenic is one of 11 pollutants of concern addressed in the LaMPs. It is an inorganic pollutant which is naturally occurring in the environment as well as being used for the hardening of copper, lead, and alloys. The major use of arsenic in the U.S. is as a wood preservative.
