How much is arsenic poisoning and how long will it take to die? Ps: I just want to write detective stories. I have no strange ideas. I hope my writing is rigorous. Thank you o (∩ _ ∩) o.

Arsenic trioxide, chemical name, slightly soluble in water, the toxic dose is 0.005-0.05g and the lethal dose is 0. 1-0.2g at normal temperature and pressure.

If necessary, you can also look at the following paragraph:

Invasion route: inhalation and ingestion.

Health hazard: it mainly affects the permeability of nervous system and capillaries, and has a stimulating effect on skin and mucosa.

Acute poisoning: nausea, vomiting, abdominal pain, sometimes mixed stool, painful spasm of limbs, oliguria, anuria coma, convulsion, respiratory paralysis and death. Peripheral neuropathy may occur within 3 weeks after acute poisoning1-. Toxic myocarditis and hepatitis may occur. A large amount of inhalation can also cause acute poisoning, but the symptoms of digestive tract are mild, and M stripes appear on nails.

Chronic poisoning: digestive system symptoms, liver and kidney damage, skin pigmentation, hyperkeratosis or verrucous hyperplasia, multiple peripheral neuritis. Can lead to lung cancer and skin cancer.

Improper food collocation can cause arsenic trioxide poisoning. For example, when people are enjoying delicious seafood such as crayfish and crabs (according to modern scientific research, these foods are rich in the strongest antioxidants in nature)

Astaxanthin (astaxanthin in English), while eating a lot of foods and drinks rich in vitamin C, such as green peppers, tomatoes, oranges, oranges and tomato juice, orange juice, orange juice and so on.

Vitamin C will reduce the arsenic pentoxide contained in crayfish and crabs. Turn into arsenic trioxide, which will often cause chronic arsenic trioxide poisoning. Therefore, whether it is Chinese medicine or modern healthy diet,

Everyone has always stressed the need to fast vitamin C and foods and drinks rich in vitamin C when eating seafood. It is said that the food rich in vitamin C is a mixture of shrimp and seafood. According to the limit of consumption, it is impossible to cause anxiety

Toxicological data:

Acute toxicity: LD 50: 10 mg/kg (oral) in rats; 20mg/kg (taken orally by mice).

Subacute and chronic toxicity: rats ingested this product at a dose of150mg/(kg d) for 6.5 months, which had a slight effect on the growth and development of animals, and the weight of liver and kidney increased obviously, but the liver and kidney functions and blood routine were normal; Below 30mg/kg, the main organs of animals have no pathological changes.

Mutagenicity: DNA inhibition: human Hela cells 500 μ mol/L. Cytogenetic analysis: human leukocyte1200 nmol/L.

Deformity: The lowest toxic dose inhaled by mice at 9 ~ 9 ~12 days of pregnancy is 28,500 μ g/m (4 hours), which leads to abnormal development of musculoskeletal system. The lowest oral exposure dose of mice at 7 ~ 7 ~ 17d gestation is1650μ g g.

/kg, resulting in abnormal development of central nervous system. The lowest oral exposure dose of 7 ~ 7 ~ 17d pregnant mice is 8250μg/kg, which leads to abnormal development of immune and reticuloendothelial tissue system.

Carcinogenicity: IARC Carcinogenicity Review: G 1, confirming human carcinogens.

Others: The lowest toxic concentration (TCLO) inhaled by mice is 28500μ g/m (4h) (9~ 12d of pregnancy), which causes cytological changes and normal musculoskeletal development.

Hazard characteristics: Highly toxic gas will be produced when exposed to high heat and sublimation.

Combustion (decomposition) product: arsenic oxide.

Ecological data:

Ecological toxicity:

LC50:8.33/L (48h) (salmon); 0.038 mg/L (24 hours) (Daphnia).

Ec50: 31.43 ~ 73.73mg/l (5 15, 30 30 minutes) (photobacterium phosphoreum, Microtox test).

Other harmful effects:

This substance is harmful to the environment, and special attention should be paid to fish and mammals.
