Are cobalt salts toxic?

Toxicity Cobalt and its salts are relatively non toxic by ingestion. Most cases of cobalt toxicity relate to occupational skin contact or inhalation. Features Topical – Cobalt is a topical irritant and a well recognised cause of occupational contact dermatitis.

What is cobalt sulphate used for?

Cobalt sulphate is an inorganic, divalent cobalt salt of sulfuric acid, represented by the chemical formula, CoSO4. It is used in applications such as electrochemical industry, paints & inks, coloring agents, and storage batteries.

Does cobalt II sulfate have acute toxicity?

GHS Classification (29 CFR 1910.1200): Acute toxicity – oral, category 4, Sensitization – respiratory, category 1, Sensitization – skin, category 1, Carcinogenicity, category 1B, Reproductive toxicity, category 1B.

Is cobalt toxic to humans?

It can harm the eyes, skin, heart, and lungs. Exposure to cobalt may cause cancer. Workers may be harmed from exposure to cobalt and cobalt-containing products. The level of harm depends upon the dose, duration, and work being done.

How much cobalt is toxic?

* Exposure to 20 mg/m3 is immediately dangerous to life and health.

Can cobalt be absorbed through the skin?

Cobalt is mainly absorbed from the pulmonary and the gastrointestinal tracts. Absorption through the skin can occur but is low. Concomitant exposure to tungsten carbide increases the pulmonary absorption rate of cobalt metal.

How long does cobalt stay in the body?

Elevated blood levels of cobalt and chromium ions can persist for at least 1 year after revision, especially in patients with high levels of exposure.

Is cobalt toxic in water?

In higher concentrations, cobalt is toxic to humans and to terrestrial and aquatic animals and plants. At the time of issuing the report, BC MWLAP uses the Ontario guideline for the protection of freshwater aquatic life (0.9 µg cobalt/L) as a working water quality guideline.

Does cobalt contain arsenic?

Cobaltite is a sulfide mineral composed of cobalt, arsenic, and sulfur, CoAsS. Its impurities may contain up to 10% iron and variable amounts of nickel. Structurally, it resembles pyrite (FeS₂) with one of the sulfur atoms replaced by an arsenic atom.

Why is cobalt important to the human body?

Cobalt is a component of vitamin B12, which supports the production of red blood cells. Very small amounts are needed for animals and humans to stay healthy.

What does cobalt do to skin?

Association has been shown between cobalt and the development of contact allergy and eczema through direct contact with the skin as well as airborne particles [19–21]. A significant increase in risk of lung cancer in hard metal workers exposed to cobalt was shown in a group of studies [22–24].

What does cobalt poisoning do in the body?

Systemic toxic effects from excessive levels of cobalt include peripheral neuropathy, sensorineural hearing loss, vision loss, cognitive decline, cardiomyopathy, hypothyroidism, weakness, fatigue and polycythemia.

What is the antidote for cobalt?

[Unithiol, an antidote in cobalt poisoning]

What diseases can cobalt cause?

Cobalt is toxic to the heart muscle. It can cause heart muscle disease (toxic cardiomyopathy) after too much exposure. An increase in red blood cells (polycythemia) may be a symptom of too much cobalt. Not treating this issue can cause congestive heart failure.

Is cobalt a known carcinogen?

Based on the laboratory animal data, the International Agency for Research on Cancer (IARC) has determined that cobalt and cobalt compounds are possibly carcinogenic to humans.

Is cobalt a neurotoxin?

Cobalt exerts well-known and documented toxic effects on the thyroid, heart and the haematopoietic system, in addition to the occupational lung disease, allergic manifestations and a probably carcinogenic action. Cobalt neurotoxicity is reported in isolated cases, and it has never been systematically treated.

Is there cobalt in tap water?

In most drinking water, cobalt levels are less than 1–2 ppb. For most people, food is the largest source of cobalt intake.

Which food contains cobalt?

Good food sources of cobalt include:

• fish.
• nuts.
• green leafy vegetables, such as broccoli and spinach.
• cereals, such as oats.

Can you get cobalt poisoning from knee replacement?
