Acetone is often a solvent for chemicals, paints, dried lacquers, enamels, etc. It is also a solvent for cleaning, delighting water, cellulose acetate, potassium iodide and potassium permanganate.
The most common cause of patients suffering from methanol poisoning is mainly misuse of fake wine or poisoning caused by industrial alcohol. Symptoms of acute poisoning occur after about 18 to 24 hours of incubation of methanol after entering the body.
Human exposure to mercury is mainly caused by industrial pollution, dental patches, inferior Chinese herbal medicines and cosmetics that are produced in rivers and offshore waters. Mercury is also commonly used in batteries, fluorescent lamps, fluorescent lamps, thermometers, and sphygmomanometers.
If the patient has acute arsenic poisoning, the symptoms are abdominal pain, bloody stool, hemolysis, shock, acute hepatitis, renal failure and convulsions; if it is chronic poisoning, the symptoms will be skin rash, gastrointestinal symptoms and peripheral neuritis.
The increase in the concentration of hippuric acid in the urine is important for the assessment of the risk of toluene exposure. Toluene is mainly metabolized to Benzoic acid in the liver, and then forms hippuric acid with Glycine, and is eventually excreted in the urine.
If humans inhale isopropyl alcohol below 400 ppm, the respiratory tract will be slightly irritated. If humans are exposed to high concentrations of isopropyl alcohol, they can cause dizziness and even coma.
Lead exposure may result from the manufacture and use of paint pigments or coatings, glazes, the manufacture and recycling of lead batteries, and the manufacture of plastic or plastic stabilizers. Lead exposure may also come from tin-lead casting, wire and cable, image tube and fluorescent lamp manufacturing, electronic soldering and capacitor tinning, or it may come from air pollution.
Hexavalent chromium is highly toxic and corrosive. If it is acutely poisoned, it will cause skin ulcers of Chrome ulcer, perforation of nasal passages, allergic contact with dermatitis, gastrointestinal hemorrhagic gastroenteritis (lethal 1-2 grams will be fatal), acute renal failure or pulmonary edema. Exposure to hexavalent chromium for a long time may cause asthma, pneumoconiosis, and cancer (lung cancer).
Acute copper poisoning: This condition is mainly caused by food or juice contaminated by copper sulphate or copper food. If you eat a lot of copper, it will cause severe nausea, vomiting with greenish blue, abdominal pain, diarrhea, vomiting blood, degenerative hemoglobin, hematuria and other symptoms.
In animal experiments, aluminum inhibits the enzyme activity of rat nerve cells, thereby causing abnormal brain function. Moreover, aluminum will replace the position of iron in the ferritin, leading to anemia; aluminum will also replace the position of calcium in the bone, causing cartilage.
