Arsenic occurs naturally in the environment and is often found within the Earth's crust, extending its presence into soil, water and rock. Arsenic is also forced into the air during certain chemical processes, causing environmental contamination. Arsenic is a poisonous substance, classified as a metalloid.Continue Reading
Because of the location of arsenic in geological formations, the contamination of ground water and drinking water is often a concern. This is especially common in non-urban areas that contain wells for drinking. Arsenic is poisonous to any multi-cellular organism, including humans.
Because of its damaging properties, it is often used in pesticides and poisons to exterminate unwanted pests. Arsenic has other uses, such as being an ingredient in car batteries and the strengthening of copper alloys.
Arsenic is the 53rd most abundant material found within the Earth's crust, and common soil contains roughly 1 to 10 parts per million of arsenic. This metalloid is commercially produced in some countries, such as China, Chile and Morocco. The mass production of arsenic in standardized cultures, such as the United States and Europe, has primarily ceased because of the poisonous effects of the toxin.
Many mystery novels pay an homage to arsenic, as it was widely used as a murder weapon before science was able to detect its traces in a cadaver.Learn more about Chemistry
The five most abundant elements in the Earth's crust are oxygen, silicon, aluminum, iron and calcium, in that order. Sodium, potassium and magnesium are also prevalent in the Earth's crust. Carbon, hydrogen, nitrogen, oxygen, phosphorus and sulfur are abundant elements in biological systems, commonly referenced using the memory device CHNOPS. Air is made mostly of oxygen and nitrogen with small amounts of other gaseous elements, such as carbon dioxide.Full Answer >
Fluorine is found in the minerals fluorapatite, cryolite and fluorspar in the Earth's crust. It is not found as a free element in nature because it is too reactive.Full Answer >
Zinc is the 24th most abundant element located in the Earth's crust. It's also found in oceans, streams and the sun. The largest mineable amounts of zinc are located in Asia, Australia and the United States.Full Answer >
Arsenic deaths most often result from acute poisoning and involve heart failure due to hypovolemic shock. Hypovolemic shock consists of a severe loss of blood and fluids, resulting in a decrease in cardiovascular function.Full Answer >
