A chemical burn occurs when living tissue is exposed to a corrosive substance (such as a strong acid, base or oxidizer) or a cytotoxic agent (such as mustard gas, lewisite or arsine). Chemical burns follow standard burn classification and may cause extensive tissue damage.
Chemical exposure to the skin is a common workplace injury and may also occur in domestic situations with chemicals such as bleach or drain-cleaners. The exposure of chemicals to the skin most often results in local irritation to the exposed area. [9] In some exposures, the chemical will be absorbed through the skin and will result in poisoning ...
Based on such information, citizens can identify the vulnerable zones in which severe toxic releases could cause harm or even in some cases death. In 1990 the Chemical Safety and Hazard Investigation Board (CSB) was established by the Congress, though it did not become operational until 1998. The Board's mission is to determine the root causes ...

Toxicity is the degree to which a chemical substance or a particular mixture of substances can damage an organism. [1] Toxicity can refer to the effect on a whole organism, such as an animal, bacterium, or plant, as well as the effect on a substructure of the organism, such as a cell (cytotoxicity) or an organ such as the liver (hepatotoxicity).
The strong chemical bonds that hold them together leave very little free chemical energy in the structure; they can be thought of as already corroded. When corrosion does occur, it is almost always a simple dissolution of the material or chemical reaction, rather than an electrochemical process.
Chemical burns are caused by contact with corrosive substances such as acid or alkali. Chemical burns are rarer than most other burns, though there are many chemicals that can damage tissue. The most common chemical-related injuries are those caused by carbon monoxide, ammonia, chlorine, hydrochloric acid, and sulfuric acid.
Acute exposure to cadmium fumes may cause flu-like symptoms including chills, fever, and muscle ache sometimes referred to as "the cadmium blues." Symptoms may resolve after a week if there is no respiratory damage. More severe exposures can cause tracheobronchitis, pneumonitis, and pulmonary edema. Symptoms of inflammation may start hours ...
