اقرأ أكثرThallium is a chemical element with the symbol Tl and atomic number 81. It is a gray post-transition metal that is not found free in nature. When isolated, thallium resembles tin, but discolors when exposed to air.Chemists William Crookes and Claude-Auguste Lamy discovered thallium independently in 1861, in residues of sulfuric acid production. Both used the newly …

اقرأ أكثرThallium poisoning is poisoning that is due to thallium and its compounds, which are often highly toxic. Contact with skin is dangerous and adequate ventilation should be provided when melting this metal. Many thallium compounds are highly soluble in water and are readily absorbed through the skin. Exposure to them should not exceed 0.1 mg per m 2 of skin in an 8 …
اقرأ أكثرINTRODUCTION. Solutions of thallium salts are colorless, tasteless, odorless, and highly toxic, with an estimated lethal dose ranging between 10-15 mg/kg[1-3].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].
اقرأ أكثرThallium is tasteless and odorless and has been used by murderers as a difficult to detect poison. It is found in trace amounts in the earth's crust. Thallium has not been produced in the United States since 1984, but is imported for use in the manufacture of electronics, low temperature thermometers, optical lenses, and imitation precious jewels.

اقرأ أكثرThallium enters the environment primarily from coal-burning and smelting, in which it is a trace contaminant of the raw materials. It stays in the air, water, and soil for a long time and is not broken down. Some thallium compounds are removed from the atmosphere in rain and snow. It's absorbed by plants and enters the food chain.
اقرأ أكثرThallium (Tl) is an extremely harmful metal that is substantially distributed in the environment. It can threaten human health via consumption of food potentially derived from Tl-contaminated agricultural production. Little information is available on how to utilize biochar to remediate Tl contamination in agricultural soils. More efforts are urgently needed to be …
