Section VI – Health Hazard Data cont...

Lead - Acute or long-term excessive inhalation exposures to the fumes or dusts of inorganic lead compounds (such as lead oxide) can adversely affect several organ systems including the nervous systems, the digestive system, the blood and blood-forming system and the renal system. Early effects are characterized by fatigue, constipation, muscle aches, abdominal pains and decreased appetite. Later signs and symptoms can include anemia, pallor, a "lead line" on the gums, and reduced hand-grip strength. Lead colic produces intense abdominal cramping which can be accompanied by constipation, nausea and vomiting. A condition called "Wrist Drop" can develop if the peripheral nervous system is affected. Severe central nervous system effects (referred to as lead encephalopathy) usually only occurs after heavy and rapid lead exposures. Signs and symptoms may include headache, dizziness, convulsions, delirium coma, and possible death. Long-term lead exposures can also produce kidney damage with possible decreased renal function resulting in urine constituents in the blood.

Manganese - Exposure may cause irritation of eyes, nose and throat, metallic taste in the mouth and metal fume fever. Advanced exposure symptoms may include weakness, sleepiness, nervousness, lack of coordination, uncontrollable laughter, mental confusion, speech disturbances and aggressiveness. It may cause bronchitis pneumonitis and central nervous system disturbances.

Molybdenum - It may cause respiratory tract irritation, liver and kidney damage and bone deformity.
