From a toxicological point of view, sulfur is a low-toxicity chemical, but it still has high toxicity.
The chronic toxicity of dozens of grams of sulfur accumulation is sufficient to damage the liver and kidneys. Studies have confirmed that sulfur damages the renal tubules and glomeruli, causing interstitial nephropathy, renal necrosis, etc., and can lead to renal failure and even death. Sulfur contains a lot of heavy metals. A small amount of consumption will cause certain damage to human internal organs. Long-term consumption will cause interstitial kidney disease, mental decline, and dullness. Especially sulfur dioxide, which occurs when sulfur is oxidized, is highly toxic to the human body. It will react violently when it comes in contact with halogens, metal powders, etc. Sulfur is a poor conductor, it is easy to generate static charge during storage and transportation, which can cause sulfur dust to catch fire. When dust or steam is mixed with air or oxidant, an explosive mixture is formed.
Even if you eat foods made from industrial sulfur, it will cause damage to the human nervous system. In mild cases, symptoms such as dizziness, vertigo, and general fatigue may occur. These heavy metal substances can seriously affect human liver and kidney functions.
Long-term intake of such foods and sulfur will cause chronic poisoning, which means that your body will be damaged unconsciously. Chief physician Hu Manjing of the Department of Traditional Chinese Medicine at Zhongda Hospital of Southeast University told reporters that this heavy metal and other chemical raw materials are very harmful to the blood system. Director Hu said that in clinical practice, there are more and more cases of unexplained hematological diseases at a young age. It is undeniable that this is related to environmental pollution and exposure to carcinogens. The safety issues caused by the addition of harmful chemicals to food cannot be tolerated. Ignore. These toxic substances enter the blood circulation and compete with your red blood cells, which is one of the factors that induce blood diseases.
Sulfur combines with oxygen to form sulfur dioxide, which becomes sulfurous acid when it encounters water. When sulfurous acid enters food, it not only destroys vitamin B1 in the food, but also makes calcium form insoluble substances, which affects the body's absorption of calcium. Free sulfurous acid also has a stimulating effect on human gastrointestinal. If the fumigated food uses industrial sulfur, more serious poisoning will occur after human consumption.
After a sulfur accident occurs, there are generally several situations such as inhalation, ingestion, and absorption through the skin. Because it can partially transform in the intestine

It is absorbed for hydrogen sulfide, so a large amount of oral administration can cause hydrogen sulfide poisoning. The systemic toxic effects of acute hydrogen sulfide poisoning are manifested as central nervous system symptoms, such as headache, dizziness, fatigue, vomiting, and coma. Sulfur can also cause conjunctivitis and skin eczema. It is weakly irritating to the skin.
Sulfur contains a lot of arsenic. The ancient "Pharmacopoeia" contains the method of removing arsenic from tofu from sulfur and the method of oil roasting, but the removal rate is low. With water washing and fine grinding, the removal rate can reach 31% and 42%.
In the event of a sulfur leakage accident, the leakage contaminated area should be isolated, access should be restricted, and the fire source should be cut off. Emergency response personnel should wear self-priming filter dust masks and general work clothes. Personnel should not directly touch the leakage. When there is a small amount of leakage, avoid raising dust, use a clean shovel to collect the leakage in a dry, clean, covered container and transfer it to a safe place. When a large amount of leakage occurs, cover it with plastic sheeting or canvas to reduce scattering, and then use non-sparking tools to collect and recycle or transport to waste disposal sites for disposal.
Employees who come into contact with sulfur generally do not need special protection. They can wear general work protective gloves and general work clothes. When the dust concentration in the air is high, wear a self-priming filter dust mask.
When sulfur poisoning occurs, if it comes in contact with the skin, remove the contaminated clothing and rinse the skin thoroughly with soap and water. If eye contact occurs, rinse with running water or normal saline, and then seek medical attention. If it is inhaled poisoning, let the poisoned person quickly leave the scene to a place with fresh air and keep the respiratory tract unobstructed.
When a fire caused by sulfur occurs, it will smother a small fire with sand. In case of a large fire, water mist can be used to extinguish the fire. Do not shoot the water directly to the molten material, so as to avoid serious fire or violent boiling. Firefighters must wear gas masks and put out the fire in the upwind direction from a safe distance.
The lead, arsenic, and sulfur in sulfur can also cause serious damage to human liver or kidney. If the fumigated food uses industrial sulfur, more serious poisoning will occur after human consumption.
Sulfur dioxide can be produced after burning sulfur, which is also a carcinogen. During production and processing, workers who inhale high concentrations of sulfur dioxide can cause swelling or spasm in the larynx, lungs, and vocal cords, which manifests as decreased speaking ability, difficulty swallowing, and suffocation.
Long-term consumption of food processed by industrial sulfur may cause cancer! ! ! (Usually most of the food treated with sulfur in the market uses industrial sulfur, which is cheap)
