THALLIUM Meaning and
Definition
-
Thallium is a chemical element with the symbol Tl and atomic number 81. It is a grayish-white metal that is highly toxic and occurs naturally in small amounts in the Earth's crust. Thallium was first discovered in 1861 by Sir William Crookes and named after the Greek word "thallos" meaning "green twig" due to the green spectral line in its emission spectrum.
In its pure form, thallium possesses a bright, silvery appearance but quickly tarnishes when exposed to air. It is a soft and malleable metal that can easily be cut with a knife. Thallium has various applications in the field of electronics, including semiconductor materials, infrared detectors, and optical fibers. It is also used in the production of glass and in certain medical imaging techniques.
However, thallium's primary usage has been in the past, as a rodenticide and pesticide, although its use has been greatly restricted due to its toxic nature. Thallium poisoning can occur through ingestion, inhalation, or skin exposure and can have severe health effects, including damage to the nervous system, digestive system, and kidneys. Symptoms of thallium poisoning may include gastrointestinal disorders, neurological abnormalities, hair loss, and even death in severe cases. Due to its toxic nature, the handling and disposal of thallium require extreme caution.
