Raws li, koj txhais li cas los ntawm polystyrene thiab styrene?

Styrene yog cov kua uas tuaj yeem sib txuas ua ke los tsim polystyrene , uas yog cov khoom yas uas qhia cov khoom sib txawv. Polystyrene yog siv los ua ntau yam khoom lag luam tseem ceeb, xws li cov ntim khoom noj khoom haus, lub ncoo rau kev xa khoom siv hluav taws xob me me, thiab rwb thaiv tsev.

Puas yog polystyrene lom rau tib neeg?

Polystyrene muaj cov tshuaj lom cov tshuaj Styrene thiab Benzene, xav tias muaj carcinogens thiab neurotoxins uas muaj kev phom sij rau tib neeg .
