PVC imaze imyaka itari mike yibasiwe cyane kandi yangwa, cyane cyane kubera isano ifitanye na chimie chorine.Bamwe bagiye bavuga ko kubera iri shyirahamwe risanzwe ridashoboka, nubwo ibyinshi muri ibyo bitekerezo byatewe n'amarangamutima aho gushingira ku bushakashatsi bwakozwe na siyansi.Nyamara kuba chlorine itanga urutonde rwibintu byihariye bya tekinike muri PVC itandukanya nizindi polymers nyinshi.Umubare wibi biranga birazwi kandi byanditse, kandi birashoboka ko iyi idasanzwe ituma iba polymer ishimishije kwiga ukurikije ubushobozi bwayo burambye.Biraramba mugukoresha kandi biragoye kumeneka.Uku gutsimbarara kwagize intego kuri bamwe mubakangurambaga, nyamara ibi birashobora kuvugwa ko ari imwe mu mbaraga zayo zikomeye duhereye ku buryo burambye.Raporo ikurikira irasuzuma - hashingiwe ku bumenyi - icyo kuramba bisobanura ku nganda za PVC n'intambwe zikenewe zaba zikenewe kugira ngo polymer irambye rwose.Icyitegererezo cyo gusuzuma cyatanzwe gishingiye kumurongo Kamere (TNS).Urwego rwa TNS ni ibikoresho bikomeye kandi bishingiye kuri siyanse byerekana ibikoresho bisobanura kuramba mu magambo adasobanutse kandi akoreshwa kandi bifasha amashyirahamwe kwishora mubikorwa byiterambere rirambye.By'umwihariko, ubushakashatsi bukubiyemo amateka yimikorere yiterambere rirambye riganisha kuri iri suzuma ririmo abadandaza bakomeye bo mu Bwongereza.
