SIGNS AND SYMPTOMS OF EXPOSURE
The most characteristic symptom of thallium exposure is alopecia
(loss of hair). Cutaneous effects may include dry, scaly skin
and impairment of nail growth often resulting in the appearance
of crescent-shaped strips across fingernails and toenails (Mees'
line). Other symptoms in acute poisoning relate chiefly to the
gastrointestinal tract, nervous system, skin, eyes, and
cardiovascular system. Acute poisoning results in swelling of
the feet and legs, arthralgia, vomiting, insomnia, hyperesthesia
and paresthesia of the hands and feet, mental confusion,
polyneuritis with severe pain in the legs and loins, partial
paralysis of the legs, angina-like pains, nephritis, wasting and
weakness, and lymphocytosis and eosinophilia. In chronic
poisoning, central and peripheral nervous system abnormalities
may persist including ataxia, tremor, incoordination, paralysis
of extremities, endocrine disorders, memory loss, and psychoses
may develop. To the best of our knowledge, the chemical,
physical, and toxicological properties have not been thoroughly
investigated.
ROUTE OF EXPOSURE
Skin Contact: May cause skin irritation.
Eye Contact: May cause eye irritation. Can cause blindness.
Inhalation: Material may be irritating to mucous membranes and
upper respiratory tract.
Multiple Routes: May be fatal if inhaled, swallowed, or absorbed
through skin.
TARGET ORGAN INFORMATION
Nerves. Cardiovascular system. Eyes. Skin. Liver. Kidneys. Male
reproductive system.
CHRONIC EXPOSURE - REPRODUCTIVE HAZARD
Result: Overexposure may cause reproductive disorder(s) based on
tests with laboratory animals.
Species: Rat
Dose: 57 MG/KG
Route of Application: Oral
Exposure Time: (60D MALE)
Result: Paternal Effects: Spermatogenesis (including genetic
material, sperm morphology,motility, and count).
