Readily oxidized as to be pyrophoric in air [Bretherick 1979. p. 120].
Профиль реактивности
Inorganic reducing agents, such as MERCURY(II) SULFIDE, react with oxidizing agents to generate heat and products that may be flammable, combustible, or otherwise reactive.
Опасность
Highly toxic by ingestion, inhalation, and
skin absorption.
Угроза здоровью
Acute poisoning can result from inhaling dust concentrations of 1.2-8.5 mg/m 3 in air; symptoms include pain and tightness in chest, coughing, and difficulty in breathing. If ingested, toxicity depends on release of t he Hg ++ ion; chronic mercury poisoning can cause kidney, mental, and nervous disturbances. Dust irritates eyes and frequently causes allergic dermatitis; absorption through skin can cause systemic poisoning.
