The statement that the atomic number of this element is 8 1 is wrong, because the atomic number is equal to the number of nuclear charges and protons, so the number of protons is 8 1, not the mass number, so it is wrong.
The causes of thallium poisoning are as follows:
Thallium poisoning can be caused by daily contact with thallium, such as ingestion of soluble thallium salts, thallium vapor and smoke absorbed through respiratory tract or skin. Thallium absorbed into blood does not bind to serum protein, but can be transported in ionic state and quickly distributed to various organs of the whole body, causing damage to the body.
Acute thallium poisoning can occur after taking thallium in a large dose at one time, and symptoms such as tachycardia, progressive hypotension, peripheral cyanosis, urinary retention, arrhythmia, lethargy and respiratory failure can occur within a few minutes.
The symptoms of chronic thallium poisoning are basically the same as those of acute thallium poisoning, but the clinical manifestations are mild. Patients may have headache, dizziness, insomnia, dreaminess, memory loss and other symptoms in the early stage.
To treat thallium poisoning patients, we must first eliminate the source of the poison and reduce thallium absorption. For example, patients with thallium poisoning should be moved to fresh air immediately, and those who pollute their skin should be washed with clear water or soapy water immediately. In case of eye contact, rinse with clear water and induce the patient who is aware of oral poisoning to vomit.
