1 Impairment of respiratory function: Disposable chopsticks must be fumigated with sulfur in the production process, so SO2 will be released when heated, which will corrode respiratory mucosa;

Damage to digestive function: disposable chopsticks are bleached with hydrogen peroxide during the production process, which is corrosive and causes corrosion to the mouth, esophagus and even gastrointestinal tract; If talcum powder is used in the grinding process, if it is not cleaned, it will slowly accumulate in the human body, causing gallstones;

Bacterial infection: the shelf life of sterilized disposable chopsticks is as long as 4 months. Once the shelf life has passed, it is likely to bring staphylococcus aureus, Escherichia coli and hepatitis.

Disposable chopsticks may also have a "greenhouse effect", because the vicious circle, fewer trees, carbon dioxide will increase, the atmosphere will become thicker, and the heat will be difficult to disperse, which will produce a "greenhouse effect."
