Tab sis Cas Benzenes?
Cov npe kuj yuav zoo ib yam, tab sis benzene TSIS yog tib yam li sodium benzoate lossis benzoic acid, yog li yog tias koj noj cov khoom muaj sodium benzoate ntxiv rau nws, koj tsis raug rau benzene. Nws tseem ceeb heev kom nkag siab tias. Muaj khi nruab nrab ntawm benzoic acid thiab benzene uas ua rau muaj kev haus luam yeeb tsawg kawg nkaus thaum xyoo 2000s.
Tom qab ntawd, qee tus muag muag dej siv cov tshuaj sodium benzoate thiab ascorbic acid (vitamin C) hauv lawv cov qauv. Cov tshuaj no muaj kev nyab xeeb nyob rau hauv ib txwm muaj kev mob, tab sis nrog rau ntau lub cev raug tshav kub, lawv tuaj yeem ua rau daim ntawv benzene. Raug rau cov roj ntau ntawm benzene paub ua kom mob qog nqaij hlav.
Vim tias qhov peev xwm rau benzene tsim muaj, FDA kuaj dua 200 dej qab zib rov qab rau xyoo 2005. Feem ntau muaj tsis muaj benzene kiag li lossis tsawg tshaj li tsib feem ntawm ib npib nyiaj, uas yog tsim kev ruaj ntseg rau tib neeg.
Nws tseem ceeb heev uas yuav tsum nco ntsoov tias kev raug feem ntau yog los ntawm cov hluav taws kub thiab roj av emissions, tsis yog los ntawm cov khoom noj los yog haus dej - txawm tias sodium benzoate thiab ascorbic acid hloov mus rau benzene, cov qib uas pom muaj nyob rau hauv ib lub raj mis soda, thiaj li tau txais kev pab tsis raug phom sij . Txawm li cas los xij, cov khw muag khoom haus cov ntaub ntawv tsim kho lawv cov khoom siv, thiab lub cev tsis muaj benzene tsis yog qhov teeb meem.
