Is Cobalt Chloride A Carcinogen?

Cobalt chloride (CAS No. 7646-79-9) is classified as hazardous: Category 2 carcinogenic substance, with the risk phrase ‘May cause cancer by inhalation’ (T; R49) in HSIS (Safe Work Australia).

Is cobalt chloride harmful?

Effects of long-term or repeated exposure
Repeated or prolonged inhalation may cause asthma. Ingestion may cause effects on the heart, bone marrow and thyroid. This substance is possibly carcinogenic to humans. Animal tests show that this substance possibly causes toxic effects upon human reproduction.

Is cobalt a carcinogen?

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. Cobalt is used in many industries.

Are cobalt salts carcinogenic?

Cobalt metal (without tungsten carbide or other metal alloys) and soluble cobalt(II) salts were classified as probably carcinogenic to humans (Group 2A) on the basis of sufficient evidence for cancer in experimental animals and strong mechanistic evidence (related to key characteristics of carcinogens in human primary

How much cobalt chloride is toxic?

Toxicity Cobalt chloride is only moderately toxic by ingestion although a 19 month-old child died some six hours after allegedly drinking only 30 mL (Jacobziner and Raybin, 1961). In another report a six year-old developed only transient gastrointestinal upset after ingesting 2.5 g (Mucklow et al, 1990).

Why is cobalt harmful to humans?

* Cobalt may cause an asthma-like allergy. Future exposure can cause asthma attacks with shortness of breath, wheezing, cough, and/or chest tightness. * Cobalt may affect the heart, thyroid, liver and kidneys. * Repeated exposure to Cobalt dust can cause scarring of the lungs (fibrosis) even if no symptoms are noticed.

Why cobalt chloride is used?

It is used as an indicator for water in desiccants. It has a role as a two-colour indicator, an allergen, a calcium channel blocker and a sensitiser. It is a cobalt salt and an inorganic chloride. It contains a cobalt(2+).

Which metal is carcinogenic?

Specifically, we focus on the five most prevailing carcinogenic metals: arsenic, nickel, cadmium, chromium, and beryllium, and their potential to drive carcinogenesis in humans.

What level of cobalt is toxic?

Adverse effects related to cobalt toxicity can occur at levels of 7-10 μg/L or more. Previously, cobalt toxicity has been seen in the form of pulmonary disease in those who inhaled cobalt dust while drilling or polishing.

What are carcinogens?

(kar-SIH-noh-jin) Any substance that causes cancer.

Is table salt a carcinogen?

A lesser known fact is that salt can also increase risk for cancer, specifically stomach cancer. The American Institute for Cancer Research (AICR) panel of experts found strong evidence that salt and salt-preserved foods increase the chance of developing stomach cancer.

Is sodium chloride a carcinogen?

Based on the studies, sodium chloride is not classified as a carcinogen.

Is cobalt chloride poison a?

A suspected carcinogen and very toxic. Cobalt chloride attacks the blood, liver, thyroid, lungs and connective tissues. It is an eye and respiratory tract irritant and a skin sensitiser.

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 toxicity reversible?

The symptoms and problems associated with long-term cobalt poisoning are rarely reversible. People who have such poisoning will likely have to take medicine for the rest of their life to control the symptoms.

Can I eat cobalt chloride?

Also, a few varieties of silica gel come coated with cobalt chloride, which is considered toxic. Swallowing a large amount at once is not too dangerous, but it may cause nausea and vomiting. For that reason, experts recommend calling a poison control center if you swallow a “do not eat” packet, just to be safe.

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 does cobalt effect the brain?

The earliest presentation of systemic cobalt toxicity can be neurological including decreased processing and motor speed, memory impairment, fine motor co-ordination and tremor. Recent literature has focused primarily on the local effects of metallosis due to failure of metal-on-metal (MoM) prostheses.

Why is cobalt so controversial?

The DRC supplies about 70 percent of the world’s Cobalt, but 80% of its industrial cobalt mines are owned or financed by Chinese companies. This dynamic has disproportionately favored China and has led to hostility among the Congolese government and its domestic mining companies.

What is the common name of cobalt chloride?

Cobalt chloride (CoCl2)

What happens when cobalt chloride is added to water?

It is an unusual material in the way it changes colour, particularly in the presence of water. Anhydrous cobalt chloride, CoCl₂, is blue in colour. As it absorbs water, it turns pink.
