By the beginning of the school year, there is no greater joy for children than the addition of some stationery. In recent days, is that true? What are the risks hidden behind the market for numerous “floating” stationery
Don't worry, plastic paper doesn't give rise to the risk of early sexual ripening
What is the meaning of the term “pull-the-skin leads to early child sex”? What are you worried about
“many of the paper skins are now plastics, and there are concerns about alkyl compounds, some of which may affect human hormones and thus sexual development.” dr. Lee morning chung, director of the endocrinology metabolism, third hospital, south medical university, was introduced。
Plastic bookskin is the heart of many children. Okay
However, debarment of the dose to talk about toxicity would be scientific. Lee morning bell states that a certain concentration of olefin compounds in need of exposure to influence sexual development has been achieved in a short period of time, and that it is clear that the normal paper skin does not meet this standard, “that high concentrations of olefin compounds will not normally be present without a particularly large heath or abnormal touch, and therefore do not affect sexual development, and that parents do not worry.”
However, this is also a reminder for parents. According to lee, there are many reasons for early sexual preparation, such as the misuse of contraceptives or animal products (such as snow clams, beehive milk, animal sexual organs, etc.), excessive exposure to skins from outside, etc., is one of the major causes of early sexual preparation, and parents need to pay particular attention to their children's diet in their daily lives。
“girls have a second form of sexual development before the age of eight, menstruation before the age of 10, sexual organ development before the age of nine, and second form of sexual development can be considered as early sexual preparation.” the lee morning bell reminds that sexual pre-literacy is classified as central and exterior, that central pre-literacy is associated with the central system, most of which is associated with diseases occurring in the hypothalamus, whereas exercisive pre-literacy is false and timely detection and early intervention is effective。
National standard plus expert advises you to choose the groceries
In fact, there has been much discussion of stationery, which, with the evolution of industrialization and the expansion of market demand, has evolved from a purely functional tool to a more demand-driven tool for paint and functionality。
During the interview, journalists found that there are many different sets of stationery in the stationery store today, and that rubber alone can be filled with a small liner, which, in addition to the most basic rubbers of wiping pencils, is broken down into specialized rubbers such as 2b, 4b and even pens; in addition, there are no considerations in the design of styles, not only “basics” such as squares, but also small animals, amphibians, etc., which are also very colourful。
It's a lot of paper. It's beautiful. It's unique
What risks could such industrial products hide? The director and director of pharmacology, chen wen peng, of the third hospital of the university of south medicine, indicated that these substances required daily attention。
First, plasticizers are widely present in plastics, represented by paper skin and plastic feet, in order to make the product softer, but plasticizers may cause damage to the central nervous system and liver and kidney function in humans. Chen wen zeng recommends parents to avoid choosing pvc (pvc) material for their children and to choose more pe (pvc) or pp (pcp) material。
In addition, attention needs to be paid to stationery with special odor, “for example, aromatic compounds such as phenylsulfonic acid, toluene, and dimethylbenzene, which may have effects on blood-making functions”
Many of these are well-colored and highly visual, while chen wen chong indicates that they often include heavy metals such as lead, copper and mercury, and that excessive exposure to heavy metals can lead to child sleep addiction and low concentration. The other white-added agent, on the other hand, makes the book particularly white and unsuited from a health point of view。
However, there is no need for excessive anxiety when used on a daily basis, and chen wenzeng suggests that avoiding the use of such products on a daily basis and avoiding tooth bites can avoid risk. “putting a stationery is a functional tool in itself, and it is a rational attitude to use it without the need to reverse it, to over-exploit its design and other functions and to return it to its original functions.”
At the national level, standards are already in place. In 2022, the latest edition of the general requirements for the safety of student materials was officially implemented, which set a limited range of school supplies for students under 14 years of age, including 14 years of age, in terms of the amount of transportable elements, the amount of hazardous substances, the brightness (whiteness), and the safety of pens. It was also mentioned that all products covered by the standard needed to indicate the applicable age range, which could provide a reference for parents in their daily selection process。
