Cov nplaim taws retardant tuaj yeem yog cov qauv sib xyaw ntawm ib lossis ob peb cov nplaim hluav taws xob, cov tawv nqaij phosphorant, thiab lwm yam kev ua kom tawv ncauj thiab tawv ntawm cov cua txias ntawm qhov kub tsawg. Feem ntau, qhov xam tau qhov tsawg-kub ntawm plastics ntawm tsawg kub txwv lawv daim ntawv thov nyob rau hauv qis-kub ib puag ncig. Nws yog ib qho tsim nyog los ntxiv qee qhov tsawg-kub tiv thaiv cov neeg sawv cev nruj me me kom hloov cov plastleness ntawm tsawg kub.
