Imikhiqizo ye-PVC inomthelela ojulile futhi oyinkimbinkimbi empilweni yabantu, futhi ingena ekuphileni kwethu kwansuku zonke ngezindlela eziningi.
Okokuqala, imikhiqizo ye-PVC isetshenziswa kabanzi emikhakheni eminingi ngenxa yokuqina kwayo, ukwakheka kwepulasitiki kanye nezindleko eziphansi, ngaleyo ndlela kuthuthukisa kakhulu ukulula kokuphila kwabantu. Emkhakheni wokwakha, izinto ze-PVC zisetshenziselwa ukwenza amapayipi, izivikelo zocingo kanye nezitezi, okuhlinzeka ngesisekelo esihlala isikhathi eside nesiqinile sezakhiwo zesimanje. Emkhakheni wokupakisha, izikhwama ze-PVC kanye nezitsha zisinikeza indlela ephumelelayo yokugcina nokuthutha ukudla, imithi kanye neminye imikhiqizo. Emkhakheni wezokwelapha, i-PVC isetshenziselwa ukwenza ama-catheter, amagilavu kanye nezinsimbi zokuhlinza, okuhlinzeka ngokusekelwa okubalulekile embonini yezokwelapha.
Kodwa-ke, ukuthandwa kwemikhiqizo ye-PVC nakho kulethe imiphumela emibi. Izinto eziyingozi, njenge-vinyl chloride monomer kanye nezithasiselo, zingase zikhiqizwe ngesikhathi sokukhiqizwa kwe-PVC, okungase kube yingozi empilweni yabantu kanye nasemvelweni.
Ngakho-ke, sidinga ukuqaphela ukuthi imikhiqizo ye-PVC inethonya elikabili empilweni yomuntu. Ngenkathi sijabulela ukulula okulethwa yi-PVC, kufanele futhi sinake izingozi zempilo nezemvelo ezingase zilethwe yiyo.
