But experts say there are steps we can take to limit our exposure. - Australia tej neeg tshawb fawb cia siab tias cov kev teeb txheeb tshiab txog tej roj hmab me me (microplastics) ntawm peb tej dej yuav txhawb nqa kom peb siv tej xub ke txhim kho uas ceev txuag thiab pov puag tau tej ib puag ncig tshaj qub ntxiv. Microplastics ces yog tej roj hmab ntwm tej khoom siv uas xuas roj hmab tsim uas tau tawg me me - uas mus xaus rau ntawm peb tej hiav txwv, tej av thiab tej cua uas peb ua pa tib si.
