In its standard state arsine is a colorless, denser-than-air gas that is slightly soluble in water (2% at 20 °C) [1] and in many organic solvents as well. [citation needed] Arsine itself is odorless, [5] but it oxidizes in air and this creates a slight garlic or fish-like scent when the compound is present above 0.5 ppm. [6]
Arsenic is a common n-type dopant in semiconductor electronic devices. It is also a component of the III–V compound semiconductor gallium arsenide. Arsenic and its compounds, especially the trioxide, are used in the production of pesticides, treated wood products, herbicides, and insecticides. These applications are declining with the ...
The metals of antiquity are the seven metals which humans had identified and found use for in prehistoric times in Africa, Europe and throughout Asia: [1] gold, silver, copper, tin, lead, iron, and mercury. Zinc, arsenic, and antimony were also known during antiquity, but they were not recognised as distinct metals until later.
Although, the advantages of copper were many, the material was too soft to find large scale usefulness. Through experimentation or by chance, additions to copper lead to increased hardness of a new metal alloy, called bronze. [3] Bronze was originally composed of copper and arsenic, forming arsenic bronze. [4]
A new study finds that honeybees forging across the U.S. ingest local pollutants, including arsenic and lead, which are detected in their honey. More than 260 samples were taken between 2020 and ...
Arsenic, a naturally occurring substance that can be found in air, water and soil but can also be released into the environment by agricultural and industrial processes such as mining and metal ...
Trimethylarsine has been reported only at trace levels (parts per billion) in landfill gas from Germany, Canada, and the U.S.A., and is the major arsenic-containing compound in the gas. [5] [6] [7] Trimethylarsine is pyrophoric due to the exothermic nature of the following reaction, which initiates combustion: AsMe 3 + 1/2 O 2 → OAsMe 3 (TMAO)
Researchers have found that toxic metals such as arsenic and lead, among other contaminants, may be present in several tampon brands in the U.S. and the U.K.
