He momo papanga kakahu tino pai te papanga ātete-hinu, kāore e ngāwari ki te pania ki te hinu, he ngāwari ki te horoi, ka whakaiti i te utu tiaki mō ngā kaihoko, nō reira he tino rongonui i te mākete kaihoko.

Ka taea e ngā matū warowaihā (PFC), hei whakaotinga mō ngā papanga iti te kaha o te mata, te whakapai ake i ngā āhuatanga ātete wai/ātete hinu o ngā papanga. Ina koa, ko ngā pūmua warowaihā mekameka roa te hua matua i te mākete. Heoi anō, ka pā pea ngā warowaihā ki te hauora o te tangata me te haumaru taiao i te wā e whakamahia ana, ā, kāore e ngāwari te pirau o ō rātou hua taha i roto i te taiao. I aukatia e te Kotahitanga o Ūropi te hoko me te whakamahi i te PFOS me te PFOA i te tau 2008. Nō reira, kua noho te kimi me te whakawhanake i ngā whakakapinga hou hei wāhanga nui o te umanga matū kakahu me te umanga tae kakahu me te whakaotinga puta noa i te ao.

Nō nā tata nei i panuitia ai e Te Whare Wānanga o Columbia tētahi momo kakahu hou e ārai ana i te hinu, kāore e whakamahi i te PFC i roto i tana whakaritenga. Ka tāpirihia e ngā kairangahau he kakano ki te mata o ia muka, ā, ka whakahaere i te matū o te mata o te rauemi muka mā te whakahaere i te rahi me te tawhiti o te kakano, kia tutuki ai tana mahi ārai hinu. I whakaatuhia e ngā hua whakamātautau kāore ngā kakahu i te mākū i te wā i iti iho ai te taumahatanga o te mata ki te 23.9mn/m, ā, he pai te pānga wehe ki te hinu rēpī, te hinu oriwa me te hinu kātoro.

Ko te kaupapa whakarite e whai ake nei: he wai-whakaaro te mata o te papanga i muri i te whakairo plasma. He maha ngā rōpū hydroxyl i hangaia i muri i te waikura o TEOS ka taea te hanga i tētahi paparanga tauhohenga ki runga i te papanga. I muri i te whakamaroke, ka taea te hanga i tētahi hanganga micro-nano me te taratara. I tua atu, i muri i te rumakina ki roto i te otinga silanol, ka taea e te nui o ngā rōpū silanol i runga i te mata o te papanga te tauhohe ki te siloxane o te 1, 3-dichlorotetrachloromethyldisiloxane, ā, ka whakaitihia tōna kaha mata. I raro i te pānga tahi o te hanganga taratara me te kaha mata iti, he āhuatanga ātete hinu tō te papanga.

Hei tāpiritanga, nā te hononga honohono i waenga i te mata o te rauemi me te muka, ka taea e ia te noho pumau ahakoa te horoi, te kakahu rānei, ā, ka mau tonu tōna pakari ki tētahi taumata. Ka whakaratohia e tēnei rangahau he tohutohu mō te whakatairanga i te whanaketanga pumau o ngā hua kakahu whai hua.
