What is Thalli's poisoning?

Thallium (TL) is a silver, soft, metal element found in trace quantities with several other metals and is usually obtained as a by -product of melting lead, copper and zinc. The minute amount of chemical, which naturally occurs in water, is relatively harmless, but Thallium is in larger quantities highly toxic and in humans can fatal up to 0.3 ounces (1 gram). It can be absorbed by skin, inhalation or ingestion orally. The element is odorless, tasteless and soluble in water; The qualities that made him a weapon of selection in several murders in Australia in the 1950s. At that time, there was little known about the risk of thallus poisoning for humans and was used in a number of over -the -counter health applications. The toxic properties of the element made it a popular component of insecticides and rodents. Over time, the research and use of the obvious tklobouk was an element that represented a serious potential danger to the general public, not if it was properly solved. In 1973 the World Health Organization DHe has supported the use of Thallium sulfate in insects and rodents of the Jedy, and most countries followed this recommendation.

The

symptoms of Thall's poisoning include extreme pain, vomiting, diarrhea, weakness and rapid hair loss. The poison is systemic, which means it can affect multiple organs including heart, lungs, kidneys and liver. The person does not have to know that he has been immediately poisoned because it may take several days to show symptoms. A person can live up to two weeks or more even after ingestion of a fatal dose

Thallium dissolves rapidly in liquids, so its presence may not always be detected by blood analysis. The best way to accurately diagnose Thalli's poisoning is to explore hair follicles. Prussian Blue, a dark blue pigment used in colors, is recommended as an antidote if served in time. The dye binds to the metal in the intestines and blocks absorption.

Prohibition of useThalia in domestic products has significantly reduced the likelihood of accidental ingestion, so when indicated by Thalli, it is generally assumed by criminal intention and the enforcement of the right to engage. In 1988, five members of the family in the United States were hospitalized by Thall's poisoning, one of whom died. The chemicals were found in non -alcoholic household drinks, but no product download started because it was an isolated incident. A little later the neighbor was convicted of a crime.

Despite the toxicity of this element, there are some commercial and medical uses for Thalia compounds. It is used to produce specialized glasses, imitation diamonds, photoelectric sensors and infrared detection and transmission devices. The medical field also uses ThalliumV under the heart stress test called myocardial perfusion test. During the treadmill or stationary cyclic stress test, the patient is given a minute dose of Thallia, which is too small to causeThalli poisoning. The patient then lies on the table where the gamma rays are monitored by Thallia through the arteries to detect any obstacles.

New research is carried out to expand the positive use of thallium, including semiconductor and medical applications. The United States continues to use product and drug product, but it has terminated all production at the age of 80. The countries involved in the recovery of Thalia include Belgium, China, Germany, Kazakhstan, Mexico, the Netherlands, Poland and Russia.
