In the beginning of the school season, many parents will add new schoolbags, new stationery, and new books to their children. Custom manufacturers of children’s schoolbags suggest that these items should be dried for two days to be safe.
Most of the student schoolbags and stationery sold on the market are made of petroleum-refined chemical fiber materials. In order to achieve the finalizing effect, they are often soaked in formaldehyde. These chemicals are harmful to children. Children with a history of allergies or children who are stimulated by these odors will react more intensely. So after buying a new schoolbag, try not to put it on your child immediately. Drying it in a ventilated place for a few days will reduce the damage to your child. In addition to new school bags and stationery, new books should also be careful not to open them in a hurry. Since the new book ink contains benzene, which is harmful to humans, it is recommended to place it in a ventilated place for two days before reading it. And some brightly colored crayons may contain a lot of lead. After being bitten or sucked unconsciously by a child, it will transfer and deposit in the body, affecting the nervous system and restricting growth and development.
