It has a stimulating effect on sputum and its compounds. It mainly enters the bloodstream from the respiratory tract and binds to the sulfhydryl group. It interferes with the activity of the enzyme, destroys the intracellular ion balance, causes the cells to be deprived of oxygen, causes metabolic disorders, and causes damage to the nervous system and other organs. Poisoned. Inhalation of excessive sputum can cause acute poisoning, which is characterized by acute onset, vomiting, decreased body temperature, and death within days or even hours of lethal dose. However, sputum poisoning is mostly chronic poisoning, dry throat, gastrointestinal pain when swallowing, vomiting nausea, weakness of limbs, diarrhea, loss of appetite, dizziness, inflammation or ulceration, and some effects on cardiac function. The minimum dose of -325 mesh sputum and its compounds that cause 50% mortality in rats is shown in the table below. Table 锑 and its compounds toxicity Bismuth and its compounds Potassium bismuth tartrate Metal antimony Sb 2 S 3 Sb 2 S 5 Sb 2 O 3 Sb 2 O 5 Minimum dose that causes 50% of deaths in mice (100g body weight) ∕mg 1.1 10.0 100 150.0 325 400 It can be seen that the toxicity of the metal ruthenium is greater than that of the ruthenium compound, the ruthenium sul Industrial hygiene standards stipulate that the maximum allowable concentration of metal ruthenium, ruthenium sulfide, ruthenium oxide and ruthenium halide at the workplace is 0.5mg ∕m 3 (in 锑), the operator should not directly contact strontium or its compounds, the production workshop Good ventilation is required.
