Abstract:
Accidental or intentional subcutaneous or intramuscular injection of metallic mercury is an uncommon form of intoxication. We present the case of a 22 year-old man, who had psychotic disorders and autoaggressive behavior, with a preceding history of self-injection of mercury into the soft tissues of the neck, thorax and abdomen. Clinical examination, radiographs, and computed tomography showed the affected area. Mercury was measured in blood and urine. The mercury was surgically resected from the affected areas. Early detection and removal of mercury from the body by physical removal or chelation is required to prevent short- and long-term toxicity.

Metal-Ligand Bonds
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...

Theory of Metallic Conduction
In this theory, Newton's second law of motion is used to determine the acceleration of an electron in the presence of an applied electric field. Then, its velocity is expressed via this acceleration.
An electron moves through the crystal, containing positive ions,...
