acid mist, a mist containing a high concentration of acid or particles of any toxic chemical, such as carbon tetrachloride or silicon tetrachloride. Such chemicals are often used by industry and stored in tanks that may leak their contents into residential areas, becoming especially dangerous if the toxic substance mixes with fog. Inhalation of acid mists may irritate the mucous membranes, the eyes, and the respiratory tract and seriously upset the chemical balances of the body. See also acid rain.
