Anonymous users2024-02-06When a person ingests 1g of sulfite a day, there will be no obvious harm, and the intake of 4 6g can cause gastrointestinal disorders and sodium sulfite.
Ingestion causes severe diarrhea, chronic poisoning, can cause headaches, kidney disorders, red blood cells and hemoglobin.
Reduction of other symptoms. In addition, because sulfur contains lead, arsenic, thallium, etc., these toxic substances can enter food during fumigation.
Sulfites can cause damage to chromosomes and DNA. Sodium bisulfite.
The biological solution of sodium sulfite (1:3) could induce a significant increase in the frequency of chromosomal aberrations (CA) in Chinese hamster pulmonary fibroblasts (CHL), and there was a clear dose-response relationship. At low concentrations, chromatidal aberrations are mainly induced, and at high concentrations, chromatidal aberrations can be caused by both chromatidal and chromosomal aberrations.
Sodium sulfite characteristics and storage attention.
Sodium sulfite physicochemical properties: it is white or yellowish-white crystal, with sulfur dioxide.
The odor is unstable in the air, slowly oxidized into sulfate and sulfur dioxide, and will decompose after being heated enough, and produce sulfur dioxide when it is decomposed by Wuchang old machine acid. It is easy to enter water, and the pH of 1% aqueous solution is strong.
Sodium sulfite needs to be stored in a cool, ventilated warehouse. Keep away from fire and heat sources. Protect from direct sunlight.
Check the tightness of the package. It should be stored separately from oxidants, acids and alkalis, and it is forbidden to mix with other dangerous goods. Prevents dust release into the workshop air.

1. **Contact.
Contaminated clothing should be removed and rinsed with plenty of running water.
2. Eye contact.
Lift the eyelids, rinse with running water or saline, and seek medical attention promptly.

Anonymous users2024-01-29Detrimental. The potassium metabisulfite in red wine is used to protect the flavor of red wine by using the sulfite in it. By detecting the content of sulfite, we can know whether there is any abnormality, which is still harmful to the human body.
Imported wines are generally sulfur dioxide with no potassium metabisulfite, because of the antioxidant effect, that is, the time to increase the shelf life;
Sulphur dioxide is partly produced during the winemaking process, and partly added later, which acts as an antioxidant, allowing the wine to stay in the bottle for a longer period of time and make the wine more stable. However, potassium metabisulfite is not significantly harmful to the population when ingesting 1g of sulfite per day, and ingestion of 4 6g can cause gastrointestinal disorders and cause severe diarrhea.
Chronic poisoning, which can cause symptoms such as headaches, kidney disorders, and a decrease in red blood cells and hemoglobin. In addition, because sulfur contains lead, arsenic, thallium, etc., these toxic substances can enter food during fumigation.
Sulfite hazard experiments.
The results showed that the development of rats was inhibited when they were fed with NaHSO3-containing diet for 2 years. Rats were fed with Na2SO3-containing diet for 2 years, and the rats developed neuritis, bone marrow atrophy and other diseases. After sulfite enters the body, it is easy to form sulfur trioxide anion radical (SO3-) through one-electron oxidation, and SO3- can react rapidly with O2 to form superoxide anion radical O2-.
When mice were injected intraperitoneally with sodium bisulfite and sodium sulfite (1:3) bioassay, it was found that the DNA of their hippocampal neuronal cells was damaged. When the concentration was , the damaged cells of male mice reached a high degree of defeat, and the length of cell DNA migration was as high, while the degree of DNA damage of hippocampal neuronal cells of female mice reached.
The cellular DNA migration length was also reached. Even at lower concentrations, cellular DNA migration length increases significantly.

National standard: In the 80s, the state once formulated a relatively loose standard, that is, the sulfur dioxide residue can reach 2% to 2% In 2003, the national standard was changed and changed to, but many companies can't do this, because if you don't add so much sodium metabisulfite, then in the end it is easy to rot and mold, so you have to add so much. Later, after coordination, it finally became, but this standard, many enterprises cannot meet it. >>>More

The outside world said it was no problem. But one of my classmates is from the Second Military Medical University, and she said that when they donated blood voluntarily, the teachers never donated anything, and the school treated teachers very well after voluntary blood donation, but no one donated it. So she told me she still felt a little bit of a problem. >>>More
