【Exposure Effects】

May be fatal if inhaled, swallowed, or absorbed through skin. May cause allergic respiratory and skin reactions. Target organs: kidneys, lungs, central nervous system, blood. Large doses of lithium ion have caused dizziness and prostration, and can cause kidney damage if sodium intake is limited. Dehydration, weight loss, dermatological effects, and thyroid disturbances have been reported. Central nervous system effects that include slurred speech, blurred vision, sensory loss, ataxia, and convulsions may occur. Diarrhea, vomiting, and neuromuscular effects such as tremor, clonus, and hyperactive reflexes may occur as a result of repeated exposure to lithium ion. Inhalation of dichromate dusts can cause ulceration and perforation of the nasal septum. Contact with breaks in the skin can cause ulceration (chrome sores). Other symptoms of exposure include erosion and discoloration of the teeth, nephritis, epigastric pain (inflammation and ulceration of the gastrointestinal tract).
