Manganese (Mn): Mn intoxication is usually due to the oxide or salts of Mn; elemental
Mn exhibits very low toxicity. The dusts and fumes can act as minor irritants to the eyes 
and respiratory tract. Both acute and chronic exposure may adversely affect the 
central nervous system (CNS), but symptoms are more likely occur after at least one or 
two years of prolonged or repeated exposures. Early symptoms may include weakness 
in the lower extremities, sleepiness, salivation, nervousness and apathy. In more 
advanced stages, severe muscular incoordination, impaired speech, spastic walking, 
mask-like facial expressions and uncontrollable laughing may occur. Manganese 
fumes have also been reported to result in metal fume fever, a u-like syndrome 
with symptoms such as dizziness, chills, fever, headache and nausea. An increased 
incidence of pneumonia, bronchitis and pneumonitis has been reported in some 
worker populations exposed to manganese. Animal studies indicate exposure may 
increase susceptibility to bacterial and viral infection.
Chromium (Cr): The toxicity and health hazards of chromium are heavily dependent 
on its oxidation state. The elemental (as in the metals), divalent and trivalent forms are 
of very low toxicity. The hexavale nt form (such as occurs in chromates and chromic 
acids) is very toxic and can produce both acute and chronic effects. Adverse effects 
on the skin may include ulcerations, irritative dermatitis and allergic skin reactions. 
Adverse effects on the respiratory system may include bronchospasms, edema, 
hypersecretion, bronchitis, irritation, allergic asthmatic reactions, and, ulceration and 
perforation of the nasal septum. Respiratory symptoms may include coughing and 
wheezing, shortness of breath and nasal itch. Eye irritation or inammation can also be 
produced. Exposure to some hexavalent chromium compounds has also been shown 
to be associated with an increased risk of lung cancer.
Nickel (Ni): Ni fumes and dust are respiratory irritants and may cause severe 
pneumonitis. Skin contact with nickel and its compounds may cause an allergic 
dermatitis. The resulting skin rash is often referred to as “nickel itch”. Ni and its 
compounds may also produce eye irritation, particularly on the inner surfaces of the 
eyelids (i.e. the conjunctiva). Animal and/or epidemiology studies have linked nickel 
and certain nickel compounds to an increased incidence of cancer of the lungs and 
nasal passages. 
Copper (Cu): Inhalation of copper fume may cause irritation of the eyes and throat 
and a u-like illness called metal fume fever. Signs and symptoms of metal fume fever 
include fever, muscle aches, nausea, chills, dry throat, cough and weakness. Cu fume 
may also produce a metallic or sweet taste. Repeated or prolonged exposure to Cu 
fume may cause discoloration of the skin or hair.
Aluminum (Al): There are no reported known health effects. Aluminum is generally 
considered to be in the nuisance dust category.
