In order to avoid children being affected by toxic and harmful substances, parents need to pay attention to the following issues when purchasing and using plastic products:

1, parents and teachers should properly guide children in the use of toys or stationery, do not habitually put toys or stationery into the mouth for a long time to bite, so as not to bring toxic and harmful substances into the mouth. If possible, use non-plastic children's products.

2, try to buy qualified plastic products produced by well-known enterprises in regular stores, and check whether the safety logo of plastic products is complete when purchasing.

3, plastic products should be selected according to the use and digital identification of plastic products. Common materials such as polypropylene (PP) are preferred for baby bottles (the middle number of the triangular seat number at the bottom of the container is 7). Baby bottles made of retired polycarbonate (PC) cannot be purchased because BPA may be migrated during use. The pacifier products are made of silicone rubber, and the tableware is made of melamine, polypropylene and other materials.

4. Choose plastic products with good appearance. When purchasing plastic products, it is necessary to see whether the appliance has obvious deformation, color difference, whether the surface is smooth, whether the bottom is uneven, whether the decal pattern is clear, whether there is wrinkles and bubbles. Colored tableware can try to use a white napkin to wipe back and forth to see if there is a phenomenon such as fading.

5. Toys should be disinfected frequently before use. Attention should be paid to disinfection methods, such as toys should avoid using ultraviolet light to disinfect, so as not to accelerate the release of polycyclic aromatic hydrocarbons.

6, plastic products should be replaced in time after a period of use, so as not to bring out harmful substances when plastic aging.

7. Preferentially select supplies with less printing and lighter colors to reduce the possibility of harmful substances such as heavy metals entering the body.
