Ko te hikoi tonu o te whakaitiiti puta noa i ngā ahumahi—mai i te hanga haurua-haurua ki ngā papa hiko tānga matatau (PCB) me ngā miihini moroiti—kua whakanui ake i te hiahia mō te ine inenga tino tika me te taea te whakahoki. Kei te pūtake o tēnei hurihanga ko te Taputapu Ine Whānui Raina Aunoa, he taputapu nui mō te whakahaere kounga me te arotau tukanga. Ka neke atu ēnei pūnaha matatau i tua atu i te tirotiro whatu ngawari, e whakawhirinaki ana ki ngā pūoko kore-pa atu matatau, ngā rauropi matatau, me te mea tino nui pea, he turanga mō te pumau miihini e kore e kitea: ngā wāhanga miihini karāhe.
Ko te mahi whānui o tētahi taputapu ine tere-teitei, tino tika hoki, he mahi tika nā ōna wāhanga. Ahakoa ko ngā whatu, ngā kāmera, me ngā pūmanawa tukatuka te mea e hopu ana i te aro, ko te pumau o te tūāpapa tūturu—ko te hanganga tonu e pupuri ana i ngā pūoko kia tino tika te tūnga—koinei te mea e whakatau ana i te tino tika ka taea. Koinei te wāhi e tino hira ai te kōwhiringa hangarau o ngā wāhanga miihini o te Taputapu Ine Whānui Raina Aunoa, e ārahi ana i te tini o ngā kaihanga matua ki te whiriwhiri i te karāhe hei rauemi whiriwhiri mō ngā turanga, ngā pou, me ngā wāhanga e mau ana i te hau.
Te Tūranga Hiranga o te Pūmautanga Mīhini i roto i te Ine Tauine
Ko te ine tika i te whānui o te rārangi he maha ngā wā ka uru ki te kimi i ngā inenga i roto i te awhe maikiromita, tae atu ki te awhe iti-maikiromita. I tēnei tauine, ahakoa ngā huringa iti o te taiao, ngā hapa hanganga rānei, ka taea te whakaputa hapa ine kāore e whakaaetia. Ko te wero matua mō tētahi pūnaha aunoa ko te pupuri i te whanaungatanga ā-wāhi i waenga i te pūoko ine (he maha ngā wā he kāmera taumira teitei, he maikiromita taiaho rānei) me te wāhanga e inehia ana. He tino ngoikore tēnei whanaungatanga tairongo ki ētahi āhuatanga ā-tinana: te wiri, te whānui wera, me te nekeneke hanganga.
Ahakoa he kaha ngā rauemi tuku iho pērā i te maitai, te konumohe rānei, he iti noa iho ō rātou herenga ina panaia ki ngā rohe o te tika o te ine. He pai rawa atu ēnei hei kawe i te wera, ā, ka ngāwari ki te horapa tere me te kore taurite o te wera mai i ngā huringa o te pāmahana taiao, i te wera o roto rānei o te mīhini. Heoi anō, he iti noa iho te kaha o te whakamātao, ā, ka taea e rātou te tuku me te pupuri i ngā wiri, ahakoa mai i ngā motuka o roto, i ngā pūwero hau, i ngā mīhini wheketere tata rānei, ka huri hei nekehanga moroiti i te wā o te huringa ine nui.
Karāhe: He Otinga Taiao mō te Tino Tika
Ko te nekehanga ki ngā taputapu ine whānui raina aunoa, arā, ngā wāhanga miihini o te karāhe, he whakatau hangarau āta whakaarohia i runga i te huinga āhuatanga ā-tinana ahurei o te rauemi e waiho ana hei turanga pai mō te ine ine tino tika.
Ko tētahi o ngā painga nui o te karāhe ko tōna tauwehenga whakawhanui wera iti rawa (CTE). Ki te whakatauritea ki te maitai, ka puhoi ake te whakawhanui me te whakawhāiti o te karāhe, ā, he iti ake te tere ina pāngia e ngā rerekētanga pāmahana. He mea nui tēnei pumau wera ā-roto hei pupuri i te whirihoranga āhuahanga pumau o ngā taputapu, kia mau tonu ai te tika o te whakatikatika i mahia i te ata puta noa i te rā, ahakoa te hurihanga o te taiao wheketere.
Hei tāpiritanga, he tino kaha te karāneti ki te whakaiti i te wiri. Ko tōna hanganga tioata tūturu he tino pai ki te mimiti i te kaha miihini. Mā te tere o te whakakore i ngā wiri, ka whakaitihia e te turanga karāneti ngā wiri auau-tiketike e taea ai te whakapōrearea i ngā pānui whatu, te whakararu rānei i te tika o te tūnga o ngā wāhanga nekehanga tere-tiketike e hono ana ki te Taputapu Ine Whānui Raina Aunoa. Mā tēnei āhuatanga whakaiti teitei ka taea e te taputapu te whakatutuki i te tere o te ine me te kore e whakararu i te whakataunga me te tika e hiahiatia ana mō ngā tukanga hanga matatau.
Ko tētahi atu āhuatanga whakamīharo ko te papatahi me te pakari o te karāhe. Mā roto i ngā tukanga whakakī me te whakaoti motuhake, ka taea e te karāhe te whakatutuki i ngā ātete papatahi o te mata i roto i te awhe iti-micrometer, ka waiho hei papa tino pai mō ngā pūnaha kawe hau tika e hiahia ana ki te nekehanga papatahi tino pai. Mā tēnei pakari ā-roto ka whakarite kia ātete te papa e tautoko ana i te tuaka ine ki te piko i raro i ngā kawenga hihiri o ngā wāhanga aunoa, ka whakamana i te pumau o te papa tohutoro i te wā e whakahaerehia ana.
Te Hononga o te Mana Nekehanga me te Granite
I roto i tētahi pūnaha aunoa katoa, me neke te wāhanga mahi me te tere me te tika rawa. Ko te Taputapu Ine Whānui Raina Aunoa e whakawhirinaki ana ki ngā wāhanga matatau pēnei i ngā motuka raina me ngā waehere tika, engari ko te whai huatanga o ēnei wāhanga ko te mata e mahi ana rātou. Hei tauira, ka whakamahia e te atamira hau-karati te pakari me te papatahi o te karati hei whakatutuki i te nekehanga kore-waku, he nekehanga tino taea te whakahoki. Mā te whakamahi i ngā āhuatanga rauemi taiao mō te pumau me te hono atu ki te mana nekehanga matatau mō te tere, ka hangaia e ngā kaihanga he mahi tahi e akiaki ana i te mahi tino pai.
He mara motuhake te hanga hangarau tika o ngā wāhanga o te karāhe. Me kimi e ngā kaihanga te karāhe pango kounga teitei, he maha ngā wā he nui ake te mātotoru me te iti ake te porosity i ētahi atu momo, kātahi ka tukuna ki ngā tukanga miihini tino tika. He maha ngā wā ka mahia ngā wāhanga huri, whakakoi, me te whakakanapa i raro i te mana whakahaere āhuarangi pakari kia tutuki ai te hua whakamutunga i ngā paerewa papatahi me te tapawhā e tika ana mō te ine ine o te ao.
Te Tirohanga ki te Anamata o te Ine Aunoa
I te mea ka haere tonu te whakaiti i ngā āhuahanga hua, ka whakawhāitihia hoki ngā manawanui hanga, ka piki haere tonu ngā tono mō ngā Taputapu Ine Whānui Raina Aunoa. Ko te turanga i whakatakotoria e ngā wāhanga karāhe tika ehara i te mea he kōwhiringa tuku iho noa iho; he mea nui mō te heke mai. Ko te whanaketanga tonu o tēnei hangarau ka kite i te whakaurunga o ngā huinga maha-pūoko kaha ake, ngā whatu whakanui teitei ake, me ngā ara nekehanga uaua haere. I ngā wā katoa, ko te pumau me te kore e memeha e whakaratohia ana e ngā wāhanga miihini karāhe ka noho tonu hei punga mō te mahi tino tika.
Mō tētahi kaihanga e mahi ana i te ao whakataetae o te hanga hangarau teitei, ehara i te mea nui te haumi ki ngā taputapu ine me te matua karāhe pakari, pumau hoki i te wera - he mea nui rautaki kia mau te mana kounga, kia whakaitihia te ngaronga hua, kia mau tonu te painga whakataetae. Ko te kaha marino o te karāhe te mea e taea ai e ngā hikohiko me ngā tirohanga matatau te mahi i tā rātou mahi uaua me te tino tika, me te kore e whakaitihia, e tino waiho ana hei toa rongonui o te ine inenga ā-ahu hou.
