Thallium (Tl) is one of the most toxic trace metals on Earth and can cause both chronic and acute poisoning. Tl is listed by both the United States Environmental Protection Agency (EPA) and the European Union (EU) as a dangerous pollutant. Tl is also considered a priority pollutant in both the 12th and 13th five-year plans in China.

Thallium is considered a cumulative poison that can cause adverse health effects and degenerative changes in many organs. The effects are the most severe in the nervous system. The exact mechanism of thallium toxicity still remains unknown, although impaired glutathione metabolism, oxidative stress, and disruption of potassium-regulated ...

Exposure to high levels of thallium can result in harmful health effects. A study on workers exposed on the job over several years reported nervous system effects, such as numbness of fingers and toes, from breathing thallium. Studies in people who ingested large amounts of thallium over a short time have reported vomiting, diarrhea, temporary ...

Symptoms of acute thallium poisoning include gastrointestinal complaints and neurological symptoms, including polyneuropathy, but the condition can also be fatal [13,14,15]. Chronic thallium toxicity can occur after long-term low-level thallium exposure, generally presenting with anorexia, headaches, and neurological symptoms [ 10, 16 ].

Thallium levels in more than twenty organs and body fluids ranged from below 1.0 to 178 microgram/gm; concentrations in twenty areas of the nervous system ranged from 29 to 140 microgram/gm. The highest brain levels of thallium were found in gray matter. In the thalamus, 87% of the thallium was present in cell sap.

The neurologic manifestations of thallium poisoning include a severely painful ascending peripheral neuropathy, autonomic dysfunction, cranial nerve abnormalities, and a toxic encephalopathy. ... As the latter mechanism is consistent with many toxin exposures, the concept of a central nervous system reservoir for thallium is often discounted. A ...

Acute thallium poisoning is usually due to ingestion of the salts, while chronic toxicity usually occurs by means of inhalation or skin absorption mostly secondary to chronic occupational exposure. ... The third phase is the elimination phase mainly through the gastrointestinal and renal system which begins 24 h later . The clinical ...

Detecting the Devil: Signs and Symptoms of Thallium Poisoning. Thallium poisoning can present a bewildering array of signs and symptoms, challenging detection and diagnosis. Acute Poisoning: In cases of acute poisoning, symptoms can manifest within one to 12 days of exposure. The affected systems and their respective signs …

This study aimed to describe organs and systems damages in persons after mass poisoning with thallium and show the results of treatment. Methods Forty-four …

Introduction. Thallium, a chemical element with the symbol TI, has an atomic number 81 on the periodic table. Thallium sulfate was once used as an ant and rat poison. [1] [2] [3] The occupational limit for thallium exposure is 0.1 mg/m^3 to the skin for eight hours a day. Levels of 15 mg/m^3 are considered immediately dangerous to one's health.

Thallium adsorption data in Magorian et al. (1974) for a hectorite clay (a rare montmorillonite clay mineral) at pH 8.1 suggest that an adsorption constant for this specific system may be approximately 19 L/g. No other information on the adsorption of thallium by earth materials was located. Thallium may be bioconcentrated by organisms from water.

Thallium (Tl +) is a toxic heavy metal that was accidentally discovered in 1861 by Sir William Crookes by burning the dust from a sulfuric acid industrial plant.He observed a bright green spectral band that quickly disappeared. The new element was named "thallium" (after thallos meaning young shoot) (Galván-Arzate and Santamaría …
