Toxicological Data
Nickel carbonate and basic nickel carbonate
The national toxicology program has listed nickel carbonate as reasonably anticipated to be a
carcinogen based on the production of injection-site tumors. However, there is reason to believe
that the compound actually tested was a basic nickel carbonate.
Sinonasal cancer has been reported in a worker employed in an operation where a nickel-copper
carbonate (formula unspecified) was decomposed to nickel-copper oxide.
Inhalation of dust may be irritating to the respiratory tract. Prolonged contact may irritate the skin and
mucous membranes. Eye contact may cause eye irritation. Chemical alleged to be nickel carbonate
but which was probably a basic nickel carbonate and dried crystalline nickel hydroxide
caused tumors at the site of injection in rodents.

Basic nickel carbonate (NiC03-Ni(OH)2 to 2Nic03-3Ni(OH)2 has a relatively low oral toxicity; its oral
rat LD5O is 1044 mg/kg. The national institute for occupational safety and health (NiOSH) concluded
that nickel and its inorganic compounds are not carcinogenic when ingested.
Refer to the toxicology of nickel.
Cobalt Carbonate
Specific information on cobalt carbonate was not found in the literature. Refer to the toxicology of
Inco cobalt.
Copper Carbonates
Material Little information specific to copper carbonate was to be found in the literature. Sources did disclose
that verdigris, formed by atmospheric corrosion of the surface of metallic copper and presumably
composed of copper carbonates and oxides, causes immediate irritation and conjunctival
inflammation when accidentally dropped or dusted on the eyes of patients but the reaction subsides
without permanent damage soon after the eye is cleansed by irrigation.
Safety Calcium carbonate calcium carbonate is considered nontoxic. Inhalation of particulates could cause
mild irritation of the respiratory tract. Although it is used as an antacid, ingestion of large amounts
could lead to intestinal blockage. Calcium carbonate is listed by the american conference of
Data governmental industrial hygienists as a nuisance particulate.
Silica
it is not known whether the silica present is amorphous or crystalline.
Sheet The international agency for research on cancer (iarc) has concluded there is limited evidence that
crystalline silica and inadequate evidence that amorphous silica causes carcinogenicity in humans.
Iarc has also concluded there is sufficient evidence that crystalline silica and inadequate evidence
that amorphous silica causes carcinogenicity in animals.
Silica is rated moderate as an acute irritating dust.
Prolonged inhalation of dusts containing free silica may result in the development of a disabling
pulmonary fibrosis known as silicosis, characterized by shortness of breath, decreased chest
expansion, lessened capacity for work, absence of fever, increased susceptibility to tuberculosis and
characteristic x-ray findings.
Amorphous silica is considered much less toxic than crystalline forms. The amorphous form does not
cause silicosis.
In some animal studies, amorphous silica has been shown to be fibrogenic, resulting in reduced lung
function.
In human studies, amorphous silica (diatomaceous earth, fused, precipitated and gel) seems to have
little adverse effect on lungs when exposures are reasonably controlled. There is not nough industrial
experience to indicate the degree of hazard for amorphous silica.
IARC states that a number of studies have shown that persons diagnosed as having silicosis after
exposure to dust containing crystalline silica have an increased risk of dying from lung cancer.
Silicosis (a pneumoconiosis of the lung) begins with symptoms of coughing, dyspnea, wheezing and
repeated non-specific chest illnesses. Impairment of pulmonary function may be progressive.
Iron III arsenate
Arsenic compounds can be absorbed by inhalation or ingestion.

Acute arsenic poisonings can be fatal. Fatal poisonings begin with symptoms of abdominal pain and
vomiting, usually within an hour of ingestion. In some cases, dermatitis and peripheral neuritis
follow recovery from acute symptoms. Acute dermatitis starts with erythema associated with burning
and itching, giving the skin a mottled appearance. If the dermatitis is on the face, swelling may
occur followed by eruptions of the skin.
The international agency for research on cancer (IARC) concluded that there was sufficient evidence
that arsenic and arsenic compounds, as a group but not necessarily as individual chemicals, were
carcinogenic to humans. An association between exposure to arsenic through contaminated drinking
Inco water and skin cancer has been observed and confirmed. Two cases of bladder cancer were also
confirmed. U.S. smelter workers exposed to inorganic arsenic have been shown to have significant
and consistent increases in lung cancer.
Material Chronic skin lesions caused by exposure to arsenic compounds are characterized by cracking,
thickening and drying of the skin, warts and excessive sweating. Dermatitis of the face and eyelids
can be accompanied by conjunctivitis with redness, swelling and pain.
Nickel
Safety the national toxicology program has listed nickel as reasonably anticipated to be a carcinogen based
on the production of injection-site tumors.
Data The international agency for research on cancer (iarc) found there was inadequate evidence that
metallic nickel is carcinogenic to humans but since there was sufficient evidence that it s carcinogenic
to animals, iarc concluded that metallic nickel is possibly carcinogenic to humans. Epidemiological
studies of workers exposed to nickel powder and to dust and fume generated in the production of
nickel alloys and of stainless steel have not indicated the presence of a significant respiratory cancer
Sheet hazard.
The inhalation of nickel powder has not resulted in an increased incidence of malignant lung tumors
in rodents.
Repeated intratracheal instillation of nickel powder produced an increased incidence of malignant
lung tumors in rats. Repeated intratracheal instillation of nickel powder did not produce an increased
incidence of malignant lung tumors in hamsters when administered at the maximum tolerated dose.
Single intratracheal instillations of nickel powder in hamsters at doses near the ld50 produced an
increased incidence of fibrosarcomas, mesotheliomas and rhabdomyosarcomas. Inhalation of nickel
powder at concentrations 15 times the exposure limit irritated the respiratory tract in rodents.
Repeated contact with metallic nickel can cause nickel sensitivity and allergic skin rashes.
Nickel metal powder has caused tumors at the site of injection in rodents. However, studies do not
suggest a significant risk for humans from nickel-containing prostheses.
The U.S. National Institute For Occupational Safety and Health (NIOSH) concluded that nickel and its
inorganic compounds are not carcinogenic when ingested. The u.s. food and drug administration
has affirmed that nickel is generally recognized as safe (GRAS) as a direct human food ingredient.
Cobalt
Asthmatic symptoms and pulmonary fibrosis occurring in the tungsten carbide industry may be
related to the inhalation of metallic cobalt dust. Evidence of polycythemia, an increase in the total red
cell mass of the blood in the body, and altered thyroid, kidney and liver function have also been
found. Excessive doses of metallic cobalt have produced cardiac changes in miniature swine.
Repeated contact with metallic cobalt can cause sensitivity resulting in allergic skin rashes or
asthma. Cobalt powders have caused tumors at the site of injection in rodents. However, studies of
cobalt-containing prostheses do not suggest a significant risk for humans.
