Q: What is the harm of gasoline to the human body? Is smelling gasoline harmful to the human body

Gasoline is mainly used as a power fuel for transportation. Rubber, paints, dyes, printing, pharmaceuticals, adhesives and other industrial gasoline as solvents. Gasoline is used as a degreaser for the washing and decontamination of machine parts and laundry, as well as for the pre-treatment of electroplating products.

The composition and toxicity of gasoline vary depending on the origin and production method. Gasoline is highly volatile and easily soluble in fats. In the production environment, it is mainly inhaled into the human body in the form of vapor through the respiratory tract, and circulates to the human brain through the blood, causing anesthetic effect.

It also has a toxic effect on the central nervous system and peripheral nerves, and also has an adverse effect on the hematopoietic function of bone marrow. The effect on the bone marrow may be due to the presence of benzene in gasoline. Acute poisoning is mild with anesthetic symptoms, mental confusion, unsteady gait, accompanied by dizziness, nausea, vomiting, conjunctival hyperemia, cough, etc.; Severe cases include coma, convulsions, muscle spasms, dilated pupils, and dull or absent light reflexes after inhaling high-concentration gasoline.

Some cases may include neck stiffness, rapid breathing, fluctuations in blood pressure, and cyanosis of the lips. Check for hepatomegaly, abnormal liver movements, and severe cases may have sequelae such as epilepsy, optic neuritis, and polyneuritis. In special cases, such as the car driver mistakenly inhales gasoline into the lungs with a suction pipe, it can cause bronchitis, chemical pneumonia and pulmonary edema, etc., and the clinical manifestations are fever, severe cough, chest tightness, blood in sputum, frequent and superficial breathing, and cyanosis of the lips.

On examination, leukocytosis may be seen. Gasoline chronic poisoning is mainly manifested by central and autonomic nervous system disorders, dizziness, headache, insomnia, nightmares, fatigue, memory loss and other neurasthenic syndromes muscle weakness, tremor, numbness of hands and feet, high and low blood pressure, excitability, moodiness, irregularity of excitement and inhibition, and some can appear hysterical-like symptoms. Exposure to gasoline** can cause dryness, chapping, and keratotic dermatitis.

Women are sensitive to gasoline, and in addition to the above-mentioned neurological symptoms, they can also have abnormal menstruation, cycle disorders, etc. The precautions are the same as for organic solvents. Patients with atopic dermatitis and pregnant women should not work in contact with high concentrations of gasoline.

The unpleasant smell of gasoline can make pregnant women feel dizzy, nauseous, vomiting, irritability, which will not only affect the appetite but also seriously affect the mental state of the pregnant woman. A large amount of tetraethyl lead is also added to the gasoline used in the transportation industry, and the lead released when the gasoline is burned is discharged into the atmosphere with the exhaust gas, and the exposure to trace amounts of lead during pregnancy can cause obvious inhibition of fetal growth and development, and the nervous system is also affected, and the birth of the baby has a significant weight loss, and the intelligence is far worse than that of the baby born to the mother who has not been exposed to lead. For safety reasons, it is best for pregnant women to stay away from gasoline exhaust environments.

Gasoline contains toxic chemicals such as lead, mercury, and benzene. If these substances are absorbed too much by the body, they can easily lead to blood diseases and liver cancer. If the amount of benzene in the human body is excessive, it will cause aplastic disorders and anemia.

Mao, director of the hematology department of a hospital in the city, told reporters that although sometimes gasoline poisoning does not show symptoms at once, if it slowly accumulates in the body, it will definitely cause some diseases. In particular, the heavy metal elements contained in gasoline are most likely to be deposited in the adipose tissue of the human body, thus causing harm to the human body. In addition, due to individual differences in metabolism, some people are more likely to be poisoned if they have too much gasoline.

Gasoline mainly damages the human nervous system, with tetraethyl lead being the most toxic. According to the national diagnostic criteria, gasoline poisoning can be divided into chronic and acute, both of which are mild, moderate and severe. At first, the symptoms caused by chronic gasoline poisoning were headache, dizziness, memory loss, insomnia, fatigue, palpitations, hyperhidrosis and other neurasthenic syndromes and autonomic nerve dysfunction. Moderate is mainly manifested by weakness of limbs; In severe cases, it manifests as toxic encephalopathy.

Acute poisoning is mainly manifested as emotional instability, crying and laughing, excitement and restlessness, accompanied by mild consciousness disorders, etc., and more serious cases can lead to limb paralysis. In addition, inhaling too much of the gas emitted by gasoline can also lead to aspiration pneumonia.
