1 Introduction. Thallium is an odorless, colorless, and rare heavy metal that occurs in nature, primarily in the form of oxides, halides, sulphates, carbonates, and acetate compounds. Thallium compounds have been widely used for rodenticides; however, due to cases of thallium poisoning, use of these compounds has been banned in many …
Control & Prevention. Rat poison is toxic to humans and can cause internal bleeding, organ failure, paralysis, and coma. The symptoms associated with ingesting, touching, or inhaling it may not appear until hours or even days after exposure. Emergency treatment is needed, as contact with rat poison can lead to death.
Symptoms of thallium toxicity are diverse in both humans and animals. The nervous system as a target organ of thallium is supported by observations from human case reports and animal studies. Relatively high doses of thallium caused neurological symptoms in humans (e.g., paresthesia of the hands and feet, weakness, tremors, coma, and …
The scariest part is that even after patients completed detoxification regiments, thallium continued to show up in their systems. For example, the thallium levels of a 52-year-old ...
Given the findings of unexplained central or peripheral nervous system disease, atrial and ventricular arrhythmias, or rapidly progressing respiratory failure, heavy-metal, especially thallium, intoxication must be considered. ... Acute thallium poisoning: toxicological and morphological studies of the nervous system. Ann Neurol. 1981; 16: 38-42.
[2.] Of the various forms of thallium, only thallium sulfate and thallium nitrate (sub-group I) dissolve in Coca–Cola without changing the appearance of the Coke or ing out of the bottle. [3.] The brown bottle found in Trepal's garage contained (a) thallium, and (b) an oxidizing ion consistent with the presence of a nitrate. [4.]
Acute thallium poisoning can cause severe central nervous system damage. In severe cases, paralysis of the respiratory muscles may occur, even leading to coma. [2,10] Here, we report on a patient in a coma caused by severe thallium poisoning and untimely diagnosis and treatment. After PB and PE treatment, as well as other …
Thallium is the most toxic among heavy metals — more toxic than lead, mercury, cadmium, or arsenic, which generally receive more medical attention. Thallium exerts various physiological effects ...
Abstract. This overview presents the updated physicochemical characteristics of thallium and its stable isotopes (205 Tl/ 203 Tl) in the context of their occurrence and fate in abiotic and biotic systems.This also deals with the thallium behavior in geochemical interactions in and between different environmental compartments and describes its …
Ms. Zhu's 72-year-old mother, Zhu Mingxin, has said she is not willing to give up, despite the authorities' refusal to reopen the investigation. "In the prime of her youth she nearly lost ...
As in humans, animal studies indicate that exposure to large amounts of thallium for brief periods of time can damage the nervous system and heart and can cause death. Animal …
Get the facts about thallium poisoning side effects, health risks and toxicity testing. Learn the metal's characteristic, uses and where it is naturally found. MedicineNet
Thallium (Tl) is released into the environment, where is present at very low levels, from both natural and anthropogenic sources. Tl is considered as one of the most toxic heavy metals; it is a non-essential metal, present in low concentrations in humans. Tl toxicity causes dermatological and gastrointestinal diseases and disorders of the …
Thallium rapidly enters the bloodstream and is transported across the whole organism, which leads to accumulation in bones, kidneys and the nervous system. In consequence, the functioning of several relevant enzymes is disrupted. Stomach and intestinal ulcers, alopecia and polyneuropathy are considered as classic syndromes of …
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 ...

In this sense, the neurological symptoms produced by Tl toxicity, making ...
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 ...
Thallium is a tasteless, odorless, and water-soluble chemical element for which both accidental intoxication and criminal poisoning have been reported. The occupational exposure limit for thallium is 0.1 milligrams (mg) per cubic meter of skin for …
A 24-hour urine thallium concentration is the standard toxicologic method and is assayed by atomic absorption photospectrometry. The normal level is less than 5 mcg/L. A urine spot test can deliver faster results. However, it often gives false-positive results, and it requires the use of 20% nitric acid, which can be dangerous and is usually ...
Symptoms of the nervous system, such as polyneuropathy, comatose, seizures, memory impairment, and mental disturbance may be the first and characterized outcome of acute thallium poisoning [ 4 - 6 ]. Recently, cases of acute thallium poisoning have been reported in developing countries, including China [ 7 - 9 ].
