1. Fireworks
The country has very strict management of thallium, and it is generally difficult to come into contact with it. But you need to be careful during festivals, because fireworks contain thallium, to be precise, thallium compound-thallium nitrate, which can produce green flames when mixed with perchloric acid, mercury chloride and resin. As long as you buy regular fireworks products and wash your hands before eating after setting off, you can avoid thallium poisoning, because thallium mainly enters the human body through the digestive tract.
2. Pesticides
Thallium sulfate was once widely used as insecticides and rodenticides, but due to some obvious side effects, it has been banned by many countries.
3. Red thallium lead ore
Red thallium lead ore is composed of elements such as lead, arsenic and thallium. Arsenic is the main component of arsenic; lead is very common in daily life and is a toxic heavy metal; thallium is the main component of rodenticide. ． ． ． ． ． It is not difficult to see from the composition that it is a proper poison.
4. Mining, metallurgy, and refining industries often come into contact with
There are dozens of thallium compounds, the common ones are: thallium sulfate, thallium nitrate, thallium acetate, thallium carbonate, and thallium phosphate , thallium oxide, thallium chloride, thallium bromide, thallium iodide, thallium hydroxide, thallium formate, thallium acetate, etc., are all highly toxic compounds.
Extended information
Thallium is more toxic to the human body than lead and mercury, and is similar to arsenic. Thallium is a non-essential trace element for the human body. It can enter the human body through drinking water, food, and breathing and be enriched. Thallium compounds are mutagenic, carcinogenic, and teratogenic, leading to various diseases such as esophageal cancer, liver cancer, and colorectal cancer. The occurrence of these diseases poses a great threat to human health.
Thallium can also compete with the Na-K-ATP (adenosine triphosphate) enzyme on the cell membrane surface to enter the cell, bind to the sulfhydryl group on the mitochondrial surface, inhibit its oxidative phosphorylation process, and interfere with the metabolism of sulfur-containing amino acids. Inhibits cell mitosis and hair follicle cuticle growth. At the same time, thallium can interact with vitamin B2 and vitamin B2 auxiliary enzymes, destroying the balance of calcium in the human body.
