Waituhi Ko te puna parahanga nui o te ahumahi tā;kua tae ki te 3 miriona taranata te whakaputanga waituhi o te ao.Ko nga tukunga parahanga parahanga o te ao o te ao (VOC) na te mangumangu kua eke ki nga rau mano taranata.Ka nui ake te kino o te haupapa i te waro, i raro i te ra o te ra ka hanga he waikura me te auahi whakaahua matū, he parahanga kino o te taiao hau, ka pa ki te hauora o te tangata.I tenei wa, ko te matuawaituhi tiaki taiaohe momo e whai ake nei:
1) Waituhi waituhi
Ka whakamahia e te waituhi-wai te wai, kaua ki te whakarewa pararopi, e tino whakaiti ana i nga tukunga VOC me te kore e pa ki te hauora o te tangata.Ehara i te mea ngawari ki te tahu, te waituhi pumau, te tae kanapa, kaore e pakaru te pereti, te mahi ngawari, te utu iti, te pai o te piri i muri i te ta, te kaha o te wai, te whakamaroke tere.Ko te ao mohio rauemi tā tiaki taiao.
2) UV waituhi whakaora
Ko te waituhi UV e pa ana ki te whakamahinga o te rama UV, he rereke nga roangaru me te kaha i raro i te whakamaaramatanga o te UV hei whakaora i te kiriata waituhi.Ma te whakamahi i te uv spectral pūngao, te here waituhi i roto i te polymerization o monomers ki waerau, Na UV waituhi tae kiriata he pai āhuatanga pūkaha me te matū.I tenei wa kua riro te mangumangu UV hei hangarau waituhi pakeke ake, he iti rawa te tukunga parahanga.I tua atu i te kore whakarewa, ko te mangumangu UV ehara i te mea ngawari ki te whakapiri, te ira maamaa, te tae kanapa, te aukati matū pai, te kai, me etahi atu painga.
3) Waituhi-a-Soy
He mea hanga te waituhi mai i te soy ki te hinu soybean kai (he hinu huawhenua maroke ranei, haurua-maroke ranei) i konatunatua ki te poaka, te kapia, te ware pi me etahi atu.Ko tenei waituhi karekau he puhui waro e whakakino ana i te hau, he hongi, he paitini, kei te whakakapi haere i te waituhi hinu kohuke.Ko tona rongonui me te whakatairanga he tino tere i Uropi, Japan me te United State.
4) Waituhi UV-wai
Ko te waituhi UV i runga i te wai kei roto i te waituhi UV kua taapirihia he wai me te 5%tiaki taiaowhakarewa, honoa ki te kapia motuhake i runga i te wai.Na tenei ka mau tonu te mangumangu i nga painga o te waituhi UV te whakaora tere, te penapena hiko, te tapuwae iti, te whakamarumaru o te taiao, engari ki te whakatutuki i te waituhi waituhi, te makuku makuku, kia pai ai nga whakaritenga o te papanga waituhi.Ko tenei mangumangu he aronga rangahau hou i te waahi o te waituhi UV.
5) Waituhi wairewa-waipiro
Ko te waituhi waipiro-wairewa kei runga i te ethanol (waipiro) ko te whakarewa matua, te kore-paitini, te haumaru, te tiaki taiao, te hauora, ko te whakakapi pai o nga hua waituhi kirihou tuku iho.I Korea ki te Tonga, Singapore, kua whakakapihia e te waituhi wairewa waipiro te waituhi toluene.Ko te waituhi wairewa-wairewa te nuinga o te mahiwhakapikohe waituhi-taiao hoki.
