How to eliminate the odor of new books?
This bad smell from new books and newspapers is harmful to human body. In the past, printing was done in type. Heavy metal lead is a toxic substance in the central nervous system, which will do great harm to human body, especially to children's psychological, intellectual and behavioral development. Now the printing industry in China has switched to film printing, so the toxicity of lead has been greatly reduced.
In the past, pure benzene ink gave off a good aromatic smell, but it was toxic and would damage people's hematopoietic system and nervous system. Although the odor emitted by organic solvents such as toluene and xylene is unpleasant, its toxicity is much lighter than that of pure benzene in previous inks, and it will not cause damage to hematopoietic system or ordinary readers, but it is unpleasant.
Extended data:
Now the black ink in the new book contains less chemicals than the color ink, so the black ink is less harmful than the color ink. The smell of new books or magazines is sometimes related to pulp, because the higher the paper quality, the higher the degree of crushing and grinding, and the more complicated the ingredients added in the production process.
However, whether it is ink or paper, its impact on human health depends on the concentration of chemicals such as organic solvents and the length of workers' working hours, which may have some impact on printing workers. But for ordinary readers, when they get books and newspapers, the chemicals in them have almost evaporated, so they don't have to worry about affecting their health.
People's Daily Online-Books and newspapers are tasteless when they are dried in the sun.
