Lauramide propyl betaine can promote the rapid penetration of chemical EDT—3Na into skin. When these chemicals are absorbed excessively by the human body, they will combine with calcium and iron to form chelates (a toxic chemical substance). If they stay in subcutaneous tissue for a long time, the barrier function of skin will decrease, and external radiation will increase, which will increase the probability of allergic dermatitis and even cause skin cancer in severe cases.
Concentrated sulfuric acid reacts with concentrated 84 to produce hydrogen chloride, which has a strong stimulating effect on eyes and respiratory mucosa. Acute poisoning: headache, dizziness, nausea, eye pain, cough, blood in sputum, hoarseness, dyspnea, chest tightness, chest pain, etc. In severe cases, pneumonia, pulmonary edema and atelectasis occur. Ulcer or opacity can be seen on the cornea. A large number of miliary red papules can appear in direct contact with the skin, resulting in flushing, pain and fever. Chronic effects: Long-term high-concentration exposure can cause chronic bronchitis, gastrointestinal dysfunction and tooth erosion. Symptoms caused by local action of hydrogen chloride include conjunctivitis, corneal necrosis, skin and mucous membrane damage, resulting in severe painful burns. Inhalation can cause rhinitis, perforation of nasal septum, tooth erosion, laryngitis, bronchitis, pneumonia, headache, palpitation and suffocation. If swallowed, it will irritate the mouth, throat, esophagus and stomach, causing salivation, nausea, vomiting, intestinal perforation, chills, fever, anxiety, shock and nephritis. Long-term exposure to low-concentration hydrogen chloride can dry and turn the skin into soil, and can also cause cough, headache, insomnia, dyspnea, palpitation and severe stomachache. The most obvious symptom of chronic poisoning is that the surface of teeth becomes rough, especially the front teeth produce spots. Patients who inhale hydrogen chloride should immediately move to a well-ventilated and pollution-free area to rest, keep warm and comfortable, and seek medical treatment as soon as possible. When eyes are irritated, wash them with water immediately and seek medical advice. Irritated skin should be washed with water every hour, then washed with soap and coated with magnesium oxide glycerin ointment, or washed with plenty of water and neutralized with 5% sodium bicarbonate solution, and then washed with clear water.
The reaction between ammonia water and hydrogen peroxide is related to its concentration. Because hydrogen peroxide is highly oxidizing, ammonia may be oxidized into nitrogen oxides such as nitrogen, nitric oxide and nitrogen dioxide with different concentrations. Inhaled gas may have no obvious symptoms or symptoms of eye and upper respiratory tract irritation, such as sore throat and dry cough. Delayed pulmonary edema and adult respiratory distress syndrome often occur after 6-7 hours incubation period. Pneumothorax and mediastinal emphysema may be complicated. Delayed bronchiolitis with vaginal obstruction occurred about 2 weeks after pulmonary edema subsided, leading to cough, progressive chest tightness, respiratory distress and cyanosis. A few patients have no obvious symptoms of poisoning after inhaling gas, but the above lesions appear after 2 weeks. Blood gas analysis showed that arterial oxygen partial pressure decreased. Chest X-ray shows pulmonary edema or miliary shadow of both lungs. High concentration of nitric oxide in nitrate gas will lead to methemoglobinemia.
Sodium pyrophosphate is generally crystalline, non-volatile, and not in direct contact, so it is possible.
Ammonia water, cold perm essence, tartaric acid, ferrous sulfate, etc. It is nothing more than irritating the nose, throat and lungs after inhalation, causing cough, shortness of breath and asthma. Or repeated contact with the skin can cause dermatitis, which is characterized by dry, itchy and red skin. If there is a wound on the skin, be sure to avoid touching the wound to prevent infection.
As for male fertility, my knowledge has little influence, but it still has influence. I can't help it I also study chemical engineering, and the influence is inevitable. Just eat more vegetables instead.
That's all I know.
