Children's picture books can't be bought casually

Picture books refer to a type of books that focus on painting and have few texts attached. Picture books are not only for telling stories and learning knowledge, but also to help children construct their spiritual world and cultivate multiple intelligences.

In order to attract children's interest in reading and capture children's attention, the packaging and printing of picture books are generally gorgeous and exquisite. In addition to increasing the cost of product packaging and the use of paper materials, manufacturers will increase the use of printing inks, solvent additives, and adhesives in order to make the colors rich and colorful. Packaging and beautifully printed paper prints often have a more pungent smell when they are just opened. Many times it is related to these raw materials, which may be mainly derived from the volatile organic compounds. The use of inks and adhesives often increases the risk of excessive volatile organic compounds and heavy metals in the product to a certain extent.

What are the possible risks of children's picture books?

01 Potential hazards of solvent residues

The production process of children’s picture books requires dozens of processes from paper to finished product. Almost every process is inseparable from the use of chemicals. Common chemicals involved include ink, fountain solution, car wash water, binding glue, Developers, etc., the use of these chemicals is a source of potential hazards for paper printed products. The taste of printed products and its impact on human health have always been the focus of people's attention.

Some compounds are toxic and harmful substances and are volatile. They are the main source of the pungent smell of children's picture books and the potential harm to the human body.

Soluble heavy metal elements

02 Potential harm to the human body

As one of the products that come into direct contact with children, children's picture books contain soluble elements that may cause potential harm to the body. The pigment particles of printed matter are very small and have strong adsorption capacity. They contain heavy metal elements such as lead, chromium, cadmium, mercury, etc., all of which are toxic. Take lead as an example. When the lead in the body accumulates to a certain level, chronic poisoning symptoms such as mental disorders, nightmares, insomnia, headaches, etc. will appear. In severe cases, fatigue, loss of appetite, nausea, abdominal distension, abdominal pain, diarrhea, etc. will appear. Lead can also enter the brain tissue through the blood, causing brain damage. According to research, children's absorption of lead is several times higher than that of adults, and lead poisoning has a greater impact on children's intelligence.
