In the case of the fire at Map Ta Phut Tank Terminal Company Limited, the source of the fire was found to be a pyrolysis gas tank containing VOCs or volatile organic compounds. Much was burned. All this directly affects health.
Volatile organic compounds Or commonly known as VOC, it refers to a group of organic compounds that evaporate easily. It can be dispersed in the air at normal temperature and pressure. The main components of the substance are carbon and hydrogen atoms, and other elements include oxygen, fluoride, chloride, bromide, sulfur and nitrogen.
“Pyrolysis gasoline” is a mixture that is toxic to the body system. Dangerous nerve compression!
dangerous! Microplastics and nanoplastics accumulate in arterial walls.
Volatile organic compounds (VOCs) in the atmosphere are classified as toxic air. In our daily life we receive this kind of substances from many products, such as rental, house paints, cigarette smoke, bleach, printing solvents. Auto Paint Store Industrial Plants, Dry Cleaning Fluids, Hair Dye Fluids and Perms Pesticides Substances that result from combustion and contaminate air, drinking water, food and beverages. Commonly used in industrial plants using solvents, such as plastic factories, refineries, petrochemicals, gray carpet factories, furniture, automobile assembly plants.
VOCs cause high levels of ozone to be released into the atmosphere near Earth. And this ozone will cause harm to humans, such as fever, malaise, sore throat, difficulty breathing, irritation of eyes, cornea, nose, throat, chest, cough and headache.
Effects of volatile organic compounds
Acute toxicity
- Exposure to benzene at high levels of concentration Breathing causes depression of the central nervous system. Arrhythmia Causes lethargy, dizziness, dizziness, rapid breathing, headache, heart palpitations, dizziness, loss of consciousness and death from failure of the respiratory system.
chronic toxicity
- Toxicity from prolonged exposure to low concentrations of benzene. It will stimulate the decrease of blood products such as red blood cells, white blood cells or platelets. The immune system is weakened. You may also experience a mild headache, nausea, loss of appetite, and abdominal discomfort. If there is severe toxicity Fatigue may occur. blurred vision and difficulty breathing
Effects on immunity
Causes disturbance or destruction of the immune system. The potential for protection from infectious diseases is reduced. For example, from a population study using blood tests. and the skin of people near toxic chemical waste dumps. The substance was found to be more present in the blood of those who were further away. The longer you stay in that area, Additionally, the white blood cells of the populations closest to the toxic waste had fewer white blood cells than those of the populations farther away.
Effects on the nervous system
Exposure to volatile organic compounds can cause many sedative symptoms, such as drowsiness, dizziness, depression or loss of consciousness, which will increase the effect.
Reproductive toxicity
Women exposed to benzene by inhalation at high concentrations May affect the reproductive system. It causes reproductive defects in women, including irregular menstruation due to shrinkage in the size of the ovaries and difficulty conceiving due to injury to the reproductive organs. However, the study is rather limited.
Harmful effects on other aspects of health
Volatile organic compounds It may impact other health systems, including the genetic system, the hormonal system, which can cause some types of cancer, and reproductive system diseases such as infertility, childhood disabilities, gender changes, etc.
Volatile organic compounds It has more or less health effects depending on the properties of the chemicals and the quantity received. The biological condition of the body and other factors, substances
- If received in large quantities Causes damage to the central nervous system. that is, to depress the central nervous system, symptoms may occur immediately may cause loss of consciousness and in
- In case of exposure VOC small amount It will cause chronic problems for a long time. It can cause cancer and can also cause tissue degeneration in internal organs
Prevent the danger deriving from volatile organic compounds.
- Reduce and avoid the use of products with high VOCs, for example by purchasing new products that do not contain VOCs
- Avoid foam, plastic containers and heating food in the microwave.
- Stop smoking
- Open the house for ventilation
- Use an air purifier
- Avoid heavy traffic as much as possible.
People who are at greater risk of harm from volatile organic compounds than the general public. These are people who have respiratory problems, such as people with asthma, young children, the elderly and people who are highly sensitive to chemicals. Furthermore, people in general who carry out work activities and those who live near sources of volatile organic compounds are also at risk.
