Plastic chairs are common plastic products in our lives, but plastics can't be used. It is reported that the toxic substances contained in general plastics are: hydrogen cyanide, also known as hydrocyanic acid. Inhalation of the respiratory tract can cause poisoning, and misuse can also cause poisoning.
The most common damage caused by benzene-containing compounds to the human nervous system is neurasthenia syndrome, which is characterized by dizziness, headache, fatigue, insomnia or multiple dreams. It can also be toxic to the human hematopoietic system. Benzene has been identified as a chemical that can cause leukemia.
Polyvinyl chloride plastic products can produce hydrogen chloride gas after combustion. People who experience contact can cause coughing, sneezing, shortness of breath, chest tightness, and runny nose and tears. Pulmonary edema can occur when inhaled high concentrations of polyvinyl chloride, and chronic bronchitis can be induced by prolonged exposure.
Toluene diisocyanate (TDI) is a low molecular compound that is widely used in the industrial field, especially in the foam, paint, paint, and plastic industries. Its harm to the human body is mainly caused by adverse effects on the respiratory system, which can cause cough, chest tightness, shortness of breath, asthma and other symptoms.
The phthalate polyvinyl chloride contains a phthalate component. Experts have found that soft plastic toys and children's products containing phthalates may be placed in the mouth by children. The long-term entry of phthalates into the human body can harm the liver and kidneys, and may also cause precocious puberty in children. Studies have shown that phthalates play a similar estrogen-like role in humans and animals, which can interfere with endocrine, reduce men's semen volume and sperm count, low sperm motility, abnormal sperm morphology, and severe testicular cancer. .
Recent studies in bisphenol a have shown that bisphenol a released from old and new plastic bottles containing room temperature water is equal. But when scientists put the bottles in boiling water, the release rate of bisphenol a was 54 times higher than before heating.
Through the above understanding, although there are many toxic substances in plastics, there is no need to worry too much. As long as you purchase qualified and good quality plastic products and use them correctly, you can avoid poisoning.
