Antimony : \An"ti*mo*ny\ (?; 112), n. [LL. antimonium, of unknown
origin.] (Chem.)
An elementary substance, resembling a metal in its appearance
and physical properties, but in its chemical relations
belonging to the class of nonmetallic substances. Atomic
weight, 120. Symbol, Sb.
Note: It is of tin-white color, brittle, laminated or
crystalline, fusible, and vaporizable at a rather low
temperature. It is used in some metallic alloys, as
type metal and bell metal, and also for medical
preparations, which are in general emetics or
cathartics. By ancient writers, and some moderns, the
term is applied to native gray ore of antimony, or
stibnite (the stibium of the Romans, and the sti`mmi of
the Greeks, a sulphide of antimony, from which most of
the antimony of commerce is obtained. Cervantite,
senarmontite, and valentinite are native oxides of
antimony.

Atomic weight: 121.75
Element of group 15. Multiple allotropic forms. The stable form of
antimony is a blue-white metal. Yellow and black antimony are unstable
non-metals. Used in flame-proofing, paints, ceramics, enamels, and rubber.
Attacked by oxidizing acids and halogens. First reported by Tholden in
1450.

Antimony : Antimony: A silvery-white earth metal which at high levels can be toxic. Antimony occurs naturally in the earth. Antimony ores are mined and then mixed with other metals to form antimony
alloys or combined with oxygen to form antimony oxide. Antimony breaks easily, but when mixed into alloys, it is used in lead storage batteries, solder, sheet and pipe metal, bearings, castings,
and pewter. Antimony oxide is added to textiles and plastics to prevent them from catching fire and is also used in paints (especially enamels), ceramics, and fireworks.
Antimony is released into the environment from natural sources and industry. In the air, antimony attaches to very small particles that may stay there for many days. Most antimony ends up in soil,
where it attaches strongly to particles that contain iron , manganese, or aluminum. Antimony is found at low levels in some rivers, lakes, and streams.
Because antimony is found naturally in the environment, the general population is exposed to low levels of it every day, primarily in food, drinking water, and air. It may be found in air near
industries that process or release it, such as smelters, coal-fired plants, and refuse incinerators. Workers in industries that process it or use antimony ore may be exposed to higher levels.
Exposure to antimony at high levels can result in a variety of adverse health effects. Breathing high levels for a long time can irritate the eyes and lungs and can cause heart and lung problems,
stomach pain and ulcers, rash on the skin or in the mouth.
Antimony can have beneficial effects. Antimony-containing compounds (meglumine antimoniate and sodium stibogluconate) are the principal medications used to treat parasite .
The NIOSH ) currently recommend the same guidelines for the workplace as OSHA.
