Sicherheit & Vorschriften

Regulatorische InformationenThe New Jersey Worker and Community Right to Know Act requires public and private employers to provide information about hazardous substances at their workplaces. (N.J.S.A. 34:5A-1 et. seq.)
DOT-KennzeichnungPoison
BrandgefahrenExcerpt from ERG Guide 151 [Substances - Toxic (Non-Combustible)]:· Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes.
GesundheitsgefahrenExcerpt from ERG Guide 151 [Substances - Toxic (Non-Combustible)]:· Highly toxic, may be fatal if inhaled, ingested or absorbed through skin.
GefahrenübersichtCauses somnolence, dyspnea, and diarrhea in lethal-dose studies of rats and mice (dermal, intraperitoneal, and oral administration)Causes CNS effects, ulceration of stomach, and diffuse hepatitis in 20-day intermittent oral study of rats[RTECS] See Arsenic and the linked occupational diseases.

Reaktive GruppeSalts, Basic
Reactivity ProfileZINC ARSENITE has only weak oxidizing or reducing powers. Redox reactions can however still occur. The majority of compounds in this class are slightly soluble or insoluble in water. If soluble in water, then the solutions are usually neither strongly acidic nor strongly basic. These compounds are not water-reactive.
Air and Water ReactionsInsoluble in water.

TreatmentZinc poisoning is treated symptomatically, often by administering fluids such as water or milk, or with gastric lavage. Arsenic poisoning can be treated by chelation therapy, using chelating agents such as dimercaprol, EDTA or DMSA. Charcoal tablets may also be used for less severe cases. In addition, maintaining a diet high in sulfur helps eliminate arsenic from the body. (L20, L49)
Gesundheitliche AuswirkungenChronic exposure to zinc causes anemia, atazia, lethargy, and decreases the level of good cholesterol in the body. It is also believed to cause pancreatic and reproductive damage. Arsenic poisoning can lead to death from multi-system organ failure, probably from necrotic cell death, not apoptosis. Arsenic is also a known carcinogen, esepcially in skin, liver, bladder and lung cancers. (T1, L20, L49)

ToxizitätsübersichtAnaemia results from the excessive absorption of zinc suppressing copper and iron absorption, most likely through competitive binding of intestinal mucosal cells. Unbalanced levels of copper and zinc binding to Cu,Zn-superoxide dismutase has been linked to amyotrophic lateral sclerosis (ALS). Stomach acid dissolves metallic zinc to give corrosive zinc chloride, which can cause damage to the stomach lining. Metal fume fever is thought to be an immune response to inhaled zinc. Arsenic and its metabolites disrupt ATP production through several mechanisms. At the level of the citric acid cycle, arsenic inhibits pyruvate dehydrogenase and by competing with phosphate it uncouples oxidative phosphorylation, thus inhibiting energy-linked reduction of NAD+, mitochondrial respiration, and ATP synthesis. Hydrogen peroxide production is also increased, which might form reactive oxygen species and oxidative stress. Arsenic's carginogenicity is influenced by the arsenical binding of tubulin, which results in aneuploidy, polyploidy and mitotic arrests. The binding of other arsenic protein targets may also cause altered DNA repair enzyme activity, altered DNA methylation patterns and cell proliferation. (T1, A17, L48, L49, A49)
Signs and SymptomsIngestion of large doses of zinc causes stomach cramps, nausea, and vomiting. Acute inhalation of large amounts of zinc causes metal fume fever, which is characterized by chills, fever, headache, weakness, dryness of the nose and throat, chest pain, and coughing. Dermal contact with zinc results in skin irritation. Exposure to lower levels of arsenic can cause nausea and vomiting, decreased production of red and white blood cells, abnormal heart rhythm, damage to blood vessels, and a sensation of
