   Izinketho zokuhlola ezifana ne-AOI noma ukuhlola okusebenzayo kwengeza ezindlekweni zokukhiqiza kodwa kubalulekile ukuze kuqinisekiswe ikhwalithi ye-PCB, ikakhulukazi emikhakheni enokwethenjelwa okuphezulu njengezezimoto nemishini yezokwelapha. Lokhu kuhlola kusiza ukuthola ukukhubazeka okungenzeka kusenesikhathi, kuqinisekiswe ukuthi umkhiqizo wokugcina uhlangabezana nezindinganiso ezidingekayo.
4. Ingabe uku-oda kwenqwaba kwehlisa kakhulu izindleko ngeyunithi ngayinye yama-PCB anohlangothi olulodwa?
   Yebo, uku-oda ngobuningi kunciphisa izindleko ngeyunithi ngayinye ngenxa yesilinganiso somnotho, njengoba izindleko zokusetha, zamathuluzi, nempahla zisatshalaliswa ngenani elikhulu. Ama-oda ngobuningi avumela abakhiqizi ukuthi bathuthukise ukusebenza kahle kokukhiqiza, okwenza ama-PCB anohlangothi olulodwa ayonga kakhulu ngezidingo zevolumu ephezulu.
5. Ngabe inkimbinkimbi yebhodi izithinta kanjani zonke izindleko zokukhiqiza zama-PCB anohlangothi olulodwa?
   Ubunkimbinkimbi bomklamo wesifunda kanye nesakhiwo sebhodi kwandisa izindleko zokukhiqiza, njengoba amaphethini ayinkimbinkimbi adinga umzila onembile, ukunemba okuphezulu ekubholeni, nezinyathelo ezengeziwe zokuhlola. Imiklamo eyenziwe lula isiza ukulawula izindleko, kodwa izakhiwo eziyinkimbinkimbi zingase zibaluleke ezinhlelweni zokusebenza ezinomsebenzi othile noma izithiyo zesikhala.
