SECTION 11. TOXICOLOGICAL INFORMATION

Routes of Entry: Inhalation, Ingestion, Skin, and Eyes.
Health Hazards(Acute and Chronic):
To the best of our knowledge the chemical, physical and toxicological properties of niobium arsenide have not been thoroughly investigated and recorded. Niobium is considered a rare earth metal. These metals are moderately to highly toxic. The symptoms of toxicity of rare earth elements include writhing, ataxia, labored respiration, walking on toes with arched back and sedation. The rare earth elemtns exhibit low toxicity by ingestion exposure. However, the intraperitoneal route is highly toxic while the subcutaneous route is poison to moderately toxic. The production of skin and lung granulomas after exposure to them requires extensive protection to prevent such exposure(Sax, Dangerous Properties of Industrial Materials, eighth edition).
Inorganic arsenic compounds are confirmed human carcinogens producing tumors of the mouth, esophagus, larynx, bladder, and para nasal sinus. A recognized carcinogen of the skin, lungs, and liver. Poisoning from arsenic compounds may be acute or chronic. Acute poisoning usually results from swallowing arsenic compounds, chronic from either swallowing or inhaling(Sax, Dangerous Properties of Industrial Materials, eighth edition).
Acute Effects:
Inhalation: DANGER-POISON. May cause irritation to the respiratorysystem, garlic odor of the breath, pallor, nervousness and depression.
Ingestion: DANGER-POISON. May cause systemic gastrointestinal and skin effects and acute arsenic poisoning.
Skin: May cause irritation and skin abnormalities.
Eye: May cause irritation.
Chronic Effects:
Inhalation: DANGER-POISON. May cause bronchitis, chronic arsenic poisoning, ulceration of the nasal septum, liver damage and cancer/ disease of the blood, kidneys and nervous system.
Ingestion: DANGER-POISON. May cause chronic arsenic poisoning, gastrointestinal disturbances, liver damage and cancer/disease of the blood, kidneys and nervous system.
Skin:May cause irritation, occasional ulceration, spotty pigmentation, dermatitis, skin cancer and keratosis(especially on soles and palms).
Eye: May cause disturbances, such as blurred vision.
Target Organs: May effect the upper respiratory system, eyes, skin, blood, liver, kidneys, skin, lungs and lymphatic system.
Carcinogenicity: NTP: Yes
IARC Monographs: Yes
OSHA Regulated: Yes
Medical Conditions Possibly Aggravated: Pre-existing skin and respiratory disorders.

About Niobium Arsenide

Arsenide IonNiobium Arsenide is a crystalline solid used as a semiconductor and in photo optic applications. An arsenide, an anion with the charge -3, is a rare mineral group consisting of compounds of one or more metals with arsenic (As). Arsenide anions have no existence in solution since they are extremely basic. These solid salts have very high lattice energies and are toxic due to the inherent toxicity of arsenic. Arsenides have applications in semiconductors, laser and light-emitting diodes, quantum dots, and optical and pressure sensors. American Elements produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia) and follows applicable ASTM testing standards. Typical and custom packaging is available. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.

Niobium has the largest magnetic penetration depth of any element and is one of three elemental type-II superconductors (Elemental Niobiumalong with vanadium and technetium). Niobium is found in the minerals pyrochlore, its main commercial source, and columbite. The word Niobium originates from Niobe, daughter of mythical Greek king Tantalus.

Arsenic Bohr ModelThe number of electrons in each of arsenic's shells is 2, 8, 18, 5 and its electron configuration is [Ar] 3d10 4s2 4p3. The arsenic atom has a radius of 119 pm and a Van der Waals radius of 185 pm. Arsenic was discovered in the early Bronze Age, circa 2500 BC. It was first isolated by Albertus Magnus in 1250 AD. In its elemental form, arsenic is a metallic grey, brittle, crystalline, semimetallic solid. Elemental ArsenicArsenic is found in numerous minerals including arsenolite (As2O3), arsenopyrite (FeAsS), loellingite (FeAs2), orpiment (As2S3), and realgar (As4S4).
