Utu Whakapā: Hangarau Matua ki roto i ngā Pūnaha Rorohiko

Tāwai he mea nui rawa kei roto i te mahi o te hoahoa me te whakatika i ngā waewae rorohiko me ngā momo whare. Ko tēnei iwi ko ngā totohu whakahaere i te paepae hāpori iti, ka whakamahia tonu hei hanga i ngā hononga ā-īra i waenganui i ngā momo hanga papanui. E whakatauhia nei te tuhinga i tana mahi ki roto i ngā pūnaha rorohiko, tana whakauru, ngā momo whakamahi, ā, ngā take taiao hoki.

Whakauru o te Utu Whakapā

Kei te whai i te ngenge rawa o ngā mete ki te hanga o te putake whakapī, pērā i te tin, lead, rautangi me etahi atu flux wāhi. Ko ngā hokohoko āwhina ko te tin-lead (Sn-Pb) me etahi whakaheke kua herehere tin-silver-copper (Sn-Ag-Cu). Kei te whai ake te taupānga o te hokohoko i runga i ngā pūtake pērā i te mata kai, te rangatira kino rānei rānei te ture ā-wāhi.

Nga Tuhinga Whakamahi

Ki te tāpiri i te putake whakapī, me whakamahia he ipu whakapī hei whakarite i tēnā, ka whai ake he waehu e pai ana ki te whakarite i te putake engari kaua e whakapae ana i ngā momo ētita rōpū rōpū. Ka haere te putake ki waenganui i ngā kaihanga rautanga, ka hanga i tētahi hononga kaha me te tauranga electrically conductive me te tauranga mechanically strong i kitea ai he hononga putake. Me whakatauhia he tikanga tika kia noho kaha ngā hononga, kāore i te pā i ngā momo ētita.

Te Uara i roto i ngā Rorohiko

Kei ngā whakahaere me te whakatika i ngā rīpora hiko, ko te take o te tae whakapiri hei whakaaetanga i te mea nui. Nā rātou i whakaiti i ngā āhuatanga katoa ki runga i ngā papa waehu tuhipoka (PCBs), e hanga ana i te tuarua whakamua mō te nuinga o ngā rīpoata hiko o tenei rā. Ki te kore ia, ka ngaro noa te mahi pai o ngā rīpoata hiko, nā te kore e taea te hanga i ngā hononga itiiti.

Ngā Whakaaro mō te Taiao

Nā ngā whakaaro mo te taiao me te hauora, kei te roa atu ngā rohe e whakamahi ana i ngā tohu whakapiri karetao kore. Kei te iti nei te maha o ngā tūtohi i tēnā wā ka whakamahi i te pūoro, nā te mea he kino, ā, kua whakaritea te whakamahi hei wāhanga i ngā tohu kē e ai ki ngā mea kē pērā i ngā kāhua whakamahaki. Nā reira, kei te tautoko i ngā take kē karetao, e whai ana i ngā painga tonu, ēngari e iti ana i te ahuwhenua me te tirotiro hauora i mua i ngā tohu matua.

Ngā Whakamahi me ngā Hono Atawhai

Ki te whakamua ngā hiranga me te hanga, ka hiahia hoki ki ngā huringa hou kia whai i te hiahia mo te mohiotanga matihiko o te taimana. Kei te whakamahia ngā pūnaha SAC (kōwhai-whero-kōwhai-mā) hei whakapai i te whakarite, te whakatika me te whakaae i ngā ture.

Heoi anō, kei te hīrahi tonu te rēwā rāpoi i roto i ngā mahi pūoro, nā tērā e āwhina ana i te hanga me te whakaora i ngā tūtohi pūtaiao i runga i te ao. Ko te whakapūmau me ngā take whakamahi, ko te whakapuaki i ngā take taiao, ka taea ai te whakaatu i te nui o tēnei mahi i te ao hanga o tenei wā me te whakapau whenua. Nā reira, ka whai ake tonu te rēwā rāpoi i te wehewehe i ngā hononga whakapai me te whakahaere i ngā tikanga pai-rawa i roto i te horopaki pūtaiao.
