Tam sim no, tsis muaj tus qauv kev lag luam sib koom ua ke rau cov ntsiab lus halogen hauv cov hnab looj tes nitrile qis-halogen. Cov tuam txhab sib txawv thiab cov lag luam thov feem ntau xa mus rau cov kev txwv hauv qab no: ＜900ppm: Hauv kev lag luam tsim khoom dav dav thiab kev lag luam hluav taws xob, cov ntsiab lus halogen saum npoo av qis dua 900ppm suav tias yog qhov txais tau. Qhov no ua tau raws li qhov yuav tsum tau ua ntawm feem ntau qhov chaw ua haujlwm raug thiab txo qis kev pheej hmoo xeb rau cov khoom siv hluav taws xob. ＜500ppm: Qee lub npe, xws li Lixin, tsim tshwj xeeb 12-nti qis-halogen hnab looj tes nitrile rau 8-nti thiab 12-nti wafer tsim, tswj cov ntsiab lus halogen qis dua qib no kom txo qis kev pheej hmoo ntawm kev ua qias tuaj rau cov khoom rhiab heev. ＜50ppm: Qee cov qauv siab kawg ntawm Cov Hnab looj tes Nitrile Qis-Halogen los ntawm Lixin tswj cov ntsiab lus halogen tag nrho (suav nrog fluorine, chlorine, bromine, thiab iodine) qis dua 50ppm. Qhov no tsis yog tsuas yog ua raws li cov cai ib puag ncig nruj xwb tab sis kuj qhia txog kev cog lus ruaj khov rau kev tiv thaiv ob qho tib si ib puag ncig tsim khoom thiab kev noj qab haus huv ntawm tus neeg siv. Rau cov kev siv tshwj xeeb hauv kev lag luam lossis cov txheej txheem, peb xav kom koj sab laj nrog cov lus qhia txog kev lag luam, cov qauv ntawm cov tuam txhab, lossis ua kev sim tshuaj xyuas kom paub meej tias cov ntsiab lus yuav tsum tau ua raws li qhov yuav tsum tau ua. Qhov no ua kom ntseeg tau tias muaj kev xaiv cov khoom tiv thaiv uas phim zoo.
