2. Kev Taw Qhia rau PAHs

Polycyclic aromatic hydrocarbons yog PAHs, uas yog lus Askiv abbreviation ntawm polycyclic aromatic.

hydrocarbons. Polycyclic aromatic hydrocarbons (PAHs) yog cov tshuaj carcinogenic heev. Lub teb chaws Yelemees muaj

tau tshaj tawm txoj cai hais tias polycyclic aromatic hydrocarbons (PAHs) yog cov tshuaj carcinogenic heev. Hluav taws xob

cov cuab yeej muag hauv Tebchaws Yelemees yuav tsum raug kuaj kom tsis pub muaj PAH ntau dhau ua ntej lawv tuaj yeem muag hauv khw. Cov

Qhov siab tshaj plaws tso cai txwv ntawm tag nrho cov nyiaj ntawm PAHs yog 10mg / kg.
