Ezweni elihlala livela lokukhiqiza izinto zikagesi, ukulawulwa kwekhwalithi yamabhodi esekethe aphrintiwe (ama-PCB) kubalulekile. Into evame ukunganakwa enomthelela omkhulu kukhwalithi ye-PCB ukusetshenziswa kwezingxenye zegwadle enqubweni yokukhiqiza. Yaziwa ngokuqina nokuzinza kwayo, i-granite idlala indima ebalulekile ekuqinisekiseni ukunemba nokunemba ekukhiqizweni kwe-PCB.
Izingxenye ze-Granite, ezifana namatafula okuhlola namajigi, zihlinzeka ngendawo ezinzile neyisicaba ebaluleke kakhulu ekuhleleni nasekuhlanganiseni ama-PCB. Izakhiwo ze-Granite ezingokwemvelo, ezihlanganisa ukumelana kwayo nokwanda kokushisayo nokudlidliza, zinomthelela endaweni yokukhiqiza engaguquki. Lokhu kuzinza kubalulekile ukuze kugcinwe ukubekezelelana okuqinile okudingekile emishinini kagesi yesimanje, njengoba ngisho nokuchezuka okuncane kungaholela ezinkingeni zokusebenza noma ukwehluleka komkhiqizo.
Ukwengeza, ukusebenzisa i-granite kunqubo yokulawula ikhwalithi kuthuthukisa ukunemba kwezilinganiso ezithathwe ngesikhathi sokuhlolwa. Amathuluzi okulinganisa anembe kakhulu, uma ebekwe endaweni engaphezulu yegwadle, anciphisa amaphutha adalwa ukungahambi kahle kwendawo. Lokhu kubangela idatha ethembeke kakhulu, okuvumela abakhiqizi ukuthi babone amaphutha kusenesikhathi emjikelezweni wokukhiqiza futhi basebenzise izinyathelo zokulungisa ngesikhathi esifanele.
Ukwengeza, izingxenye ze-granite kulula ukuzihlanza nokuzinakekela, okubalulekile endaweni yokukhiqiza lapho ukungcola kungathinta ikhwalithi ye-PCB. Imvelo engeyona i-porous ye-granite ivimbela ukumuncwa kothuli namakhemikhali, iqinisekisa ukuthi ubuso buhlala buhlanzekile futhi buvumela ukukhiqizwa kwekhwalithi ephezulu.
Sengiphetha, umthelela wezingxenye zegwadle ekulawuleni ikhwalithi ye-PCB awukwazi ukubukelwa phansi. Ngokuhlinzeka ngendawo ezinzile, enembile nehlanzekile yokukhiqiza nokuhlolwa, igwadle idlala indima ebalulekile ekuthuthukiseni ikhwalithi iyonke yama-PCB. Njengoba isidingo semikhiqizo ye-elekthronikhi esebenza kahle kakhulu siqhubeka sikhula, ukutshala imali kuzixazululo ezisekelwe kugwadule kubalulekile kubakhiqizi abahlose ukugcina inzuzo yokuncintisana nokuqinisekisa ukwethembeka komkhiqizo.
