He maha ngā āputaputa o ngā puranga witi, ā, he rerekē ngā pūngao o ngā witi rerekē, ka rerekē ai te ātete o ngā paparanga witi rerekē mō ia waeine. Ka pāngia te rere me te tohatoha o te hau i roto i te puranga witi, ka hua ake he rerekētanga. Rangahau mō te horapa me te tohatoha owhanariki pūhaumāotai roto i ngā witi rerekē e tautoko ana i te ārahi i ngā umanga rokiroki ki te whakamahiwhanariki pūhaumāotate whakapūngāwerewere hei whakawhanake i ngā mahere pai ake, whaitake ake hoki, hei whakapai ake i te hua o ngā mahi whakapūngāwerewere, hei whakaiti i te whakamahinga o ngā matū, hei whakatutuki hoki i ngā mātāpono tiaki taiao, ōhanga, akuaku me te whai hua o te rokiroki witi.
E ai ki ngā raraunga e tika ana, i whakaatuhia e ngā whakamātautau i roto i ngā whare putunga witi ki te tonga me te raki, 5-6 hāora i muri i tewhanariki pūhaumāotaI te whakamahana i runga i te mata o ngā puranga witi witi, kua tae te hau ki raro o te puranga witi, ā, 48.5 hāora i muri mai, kua eke te ōritetanga o te kukū ki te 0.61; i te 5.5 hāora i muri i te whakamahana raihi, kāore he hau i kitea i raro, i te 30 hāora i muri i te whakamahana, he nui te kukū i kitea i raro, ā, i te 35 hāora i muri mai, kua eke te ōritetanga o te kukū ki te 0.6; i te 8 hāora i muri i te whakamahana pīni soya, ko te kukū hau i raro o te puranga witi he rite tonu ki te kukū i runga i te mata o te puranga witi, ā, he pai te ōritetanga o te kukū hau i roto i te whare putunga katoa, neke atu i te 0.9.
Nō reira, ko te tere horapa ohau whanariki fluoridei roto i ngā witi rerekē ko te pīni soya>raihi>witi
Me pēhea te pirau o te hau sulfuryl fluoride i roto i ngā puranga witi witi, raihi, me te pīni soya? E ai ki ngā whakamātautau i roto i ngā whare putunga witi i te tonga me te raki, ko te toharitehau whanariki fluorideKo te haurua-ora kukū o ngā puranga witi he 54 hāora; ko te haurua-ora toharite o te raihi he 47 hāora, ā, ko te haurua-ora toharite o te pīni soya he 82.5 hāora.

Ko te hekenga o te kukū hau i roto i te puranga witi ehara i te mea e pā ana ki te ātete hau o te whare putunga anake, engari ki te mimitinga o te hau e ngā momo witi rerekē. Kua pūrongohiawhanariki pūhaumāotaE pā ana te mimiti ki te pāmahana me te nui o te makuku o te witi, ā, ka piki ake i te pikinga ake o te pāmahana me te makuku.
