I te whakanui ake i te mōhiotanga tiaki taiao i ngā whenua katoa o te ao, ka āta whakapai ake ngā ture me ngā whakaritenga tiaki taiao, inā koa ngā whakaritenga akuaku mō ngā hua kirihou pēnei i te rongoā, te tukatuka kai, ngā mea e hiahiatia ana i ia rā, me ngā kirihou takaro. Ka whakakapia katoatia ngā whakaū mata me te tote cadmium e ngā whakaū PVC kore-paitini. . Ko te hanga o ngā tāpiri kirihou o tāwāhi ka nui te tauine me te motuhake, ka tino whakanuia ngā whakaritenga tiaki taiao, ā, he whai hua, he maha ngā mahi. Kua noho te rangahau me te whakawhanake i ngā whakaū PVC hou e pai ana ki te taiao me te kore-paitini hei ia ahua e kore e taea te karo. Ko te ahunga kore-paitini o ngā whakaū wera PVC e aro nui ana ki ngā āhuatanga e rua o te whakaū wera organotin me te konupūmā-konutea, ā, kua nui te ahunga whakamua i roto i ngā mea e rua. Ko te nuinga o te wā ka kitea i roto i te rangahau angitu me te whakamahinga whānui o ngā whakaū wera organotin e tohuhia ana e te United States, me te rongonui me te tono o ngā whakaū wera konupūmā-konutea kore-paitini e tohuhia ana e te Europe, engari he tino utu nui te utu o te organotin. Ka hangaia e te whakaū wera konupūmā-konutea te pūnaha whakaū PVC kore-paitini ā muri ake nei o ngā whenua katoa o te ao.
