Health Hazards
SYMPTOMS: Symptoms associated with compounds of this class may occur weeks to months after an acute exposure to toxic concentrations. Acute and chronic symptoms are similar and include numbness and tingling of the lips, hands and feet; dysarthria, concentric constriction of the visual fields, hearing impairment and ataxia. Clumsiness, speech impairment, slight ptosis, irregular nystagmus on extremes of gaze, "jerky pursuit" and abnormal saccadic movements are common. It can cause chorea, athetosis, tremor and convulsions. Other symptoms may include irritation of the eyes, skin and mucous membranes, and emotional disturbances. Severe intoxication can produce periods of spasticity and jerking movements of the limbs, head or shoulders; bouts of groaning, moaning, shouting or crying; and incontinence. Less frequent symptoms include dizziness, hypersalivation, lacrimation, nausea, vomiting, diarrhea, constipation, kidney damage, dermatitis and skin burns. Damage tends to be irreversible. This type of compound passes through the blood brain barrier and placenta very rapidly.
