PCB ntim khoom yog cov khoom siv hluav taws xob tiag tiag, nti thiab lwm yam tsis (xws li qhov loj me ntawm cov khoom, qhov ntev thiab dav, ncaj ncaj, thaj, ncoo loj, tus pin ntev thiab dav, tus pin sib nrug, thiab lwm yam) hauv cov duab sawv cev, yog li nws tuaj yeem raug hu thaum kos duab daim duab PCB.

1) PCB ntim tau muab faib ua cov khoom siv sib txuas, cov khoom siv sib txuas, cov khoom sib xyaw (ob qho sib txuas thiab ntsaws-nyob ua ke tib lub sijhawm) thiab cov cuab yeej tshwj xeeb raws li hom kev teeb tsa. Cov cuab yeej tshwj xeeb feem ntau xa mus rau cov cuab yeej phaj phaj.

2) PCB ntim tuaj yeem faib ua pawg hauv qab no raws li kev ua haujlwm thiab cov khoom siv zoo li:
