Cov teeb meem ib puag ncig koom nrog hauv cov txheej txheem tsim khoom PCB yog qhov tshwj xeeb. Lub ntsiab lus ntawm txhuas thiab bromine yog qhov kub tshaj plaws, thiab tsis muaj txhuas thiab halogen-dawb yuav cuam tshuam rau kev loj hlob ntawm PCBs hauv ntau txoj kev. Txawm hais tias qhov kev hloov pauv ntawm cov txheej txheem kho qhov chaw ntawm PCBs tsis loj heev, thiab nws zoo li lawv tseem nyob deb, nws yuav tsum tau muab sau tseg tias kev hloov qeeb qeeb yuav ua rau muaj kev hloov pauv loj. Nrog rau qhov kev thov ntau ntxiv rau kev tiv thaiv ib puag ncig, cov txheej txheem kho saum npoo ntawm PCB yuav hloov pauv ntau yam yav tom ntej.
