Ko te kaha nui me te ahurei o te hangarua o te PVC e tohu ana me tīmata ngā hōhipera ki te PVC mō ngā kaupapa hangarua taputapu hauora kirihou. Tata ki te 30% o ngā taputapu hauora kirihou he mea hanga ki te PVC, ā, koinei te rauemi e whakamahia whānuitia ana mō te hanga putea, ngongo, kopare me ētahi atu taputapu hauora whakakorekore.
Ka wehea te toenga o te hea ki roto i ngā momo polymer e 10. Koinei tētahi o ngā kitenga matua o tētahi rangahau mākete hou i whakahaerehia e tētahi kamupene rangahau mākete me te kaitohutohu whakahaere o te ao. E matapaetia ana hoki e te rangahau ka mau tonu te PVC i tōna tūranga nama tuatahi tae noa ki te tau 2027 pea.
He ngāwari te hangarua i te PVC, ā, he whānuitia hoki ōna whakamahinga. Ko ngā taputapu e hiahia ana ki ngā wāhanga ngohengohe, pakari hoki, ka taea te hanga katoa i te kotahi polymer - koinei te kī ki te angitu o te hangarua kirihou. Ko te kaha teitei me te ahurei o te hangarua o te PVC e tohu ana me tīmata ngā hōhipera ki tēnei rauemi kirihou ina whakaarohia ana ngā mahere hangarua mō ngā para kirihou hauora.
I kōrero ngā kaimahi e pā ana ki ngā kitenga hou: "Kua whakaatuhia e te mate urutā te mahi nui a ngā taputapu hauora kirihou whakakorekore ki te aukati me te whakahaere i ngā mate urutā hōhipera. Ko te pānga kino o tēnei angitu ko te pikinga ake o te maha o ngā para kirihou hōhipera. Ki tā mātou whakaaro ko te hangarua he Wāhanga o te otinga. Waimarie, ko te kirihou e whakamahia nuitia ana i roto i te hauora koia hoki te kirihou tino hangarua, nō reira ka akiaki mātou i ngā hōhipera kia tīmata te whakamahi i te PVC mō ngā mahi hangarua."
Tae noa mai ki tēnei wā, ko te noho o ngā matū CMR (carcinogenic, mutagenic, reproductive toxicity) i roto i ētahi taputapu PVC he arai ki te hangarua PVC hauora. E kīia ana kua whakatauhia tēnei wero: "Mō te nuinga o ngā tono, kei te wātea, kei te whakamahia hoki ngā plasticizer rerekē mō te PVC. E whā o ēnei kua whakarārangihia inaianei ki te European Pharmacopoeia, he hua hauora i Ūropi me ētahi atu rohe. Kua whakawhanakehia ngā aratohu haumaru me te kounga."
