Te Rau Whakapū ki ngā Pūkaha—He Hiahia Mō ia Kairangahau Rīti

Tāwai he mea nui o ngā pūtauira hei whakauru i ngā whatu rangahau. Me mārama ki tana tu Tonga, ōna whakamahi me ētahi atu ka whai wā ka whakaaro pai ai ngā hono me te mahi pai o ngā pūtauira.

Ko te uku whakapiri he mea whakatupu i ngā mete me ngā pūnaha iti i te waengaro, ka tupeke mai ka hanga i te hononga i waenganui i rua rānei o ngā pūnaha mete. I kitea te noho ake nei e ngā iwi, inaianei ko ēnei i rohe, ko ngā hokiterangi hoki e mahi ana i te whakarite me te whakawhiti i ngā mea, pērā i ngā reoio.

Tongā me ngā Momotu:

Kei ngā whakawhitinga o te tāwai kaiwhakapuare ka hāngai tonu ki te porowhita o te tin me te lead, heoi anō hēra kē e kore ana i tēnei whakamahinga chemist ko te tin-silver-copper rānui ko te tin-copper. Ki ngā tāwai kaiwhakapuare e rerekē ana, he wā ka whai mātā waimātau aua e tīmata ana ki te pūtake inaianei, nā reira ka taea te mahi i ngā kaiwhakatū matihiko hei whakamahi hoki i ngā whakatatangi mahi nui.

Ngā Whakamahi i roto i ngā Matihiko:

Ki te whakamahi i ngā tāwai kaiwhakapuare noaiho mai ngā āhua matihiko pērā i ngā PCBs, ngā tāwai e hono ana i aua, ā, ngā pūtanga, ka whakauru atu i aua ki te hanga kotahi. Ki te hanga i ngā hononga kaha matihiko, ka taea te whakamana i ngā huataki kaha, nā reira ka whai oranga maha te oranga o ngā rorohiko matihiko, nā te konsumer electronics ki te whakahau whakatere.

Ngā momo whakapuare:

Kia whai kē te mahi tapa hei whakamahi i ngā momo tika. He aha te wero rānei he mea e whakawhiti ana i te pai ki te hanga i te hononga o ngā rauemi e rua; mā te whakawehi i te tīwai ka mōhio ai ia ki te haere i waenganui i ngā wāhanga katoa e hāpai ana i te hononga, nā te whakaroto ātū i te huringa. Ko te pai rawa ka kitea i runga i te mana moemoeā i te whakamahi i ngā momo hanga e whai ake nei i te wā i te mahi i ngā pūtake hoki, pērā i te tapa hurihanga rānei, te tapa paku-whare rānei, heoi anō hoki te tapa matawhenua rānei, hei whai hua pai.

Ngā Whakaaro mō te Taiao me te Haumanu:

Nā te nuinga o ngā whenua kua noho whakatūpato i ngā tapa e noho lead-based ana nā ngā take taiao e pā ana ki a ia, nā reira i whakapakari i ngā tapa kore-lead. Ki te iti i te whakapakari i te whakapakari i ngā hūnga tapa, me whakatauhia ngā tikanga whakawehi me ngā tikanga whakahaere katoa.

Whakakapi:

I te whakamutunga, he mea nui rawa te miro hāpuhia i roto i te whenua o ngā rorohiko, e āwhina ana i te tūpato, te whakaora, me te tirotiro mai i ngā kōmihiti rorohiko. Kua kitea e tātou ngā whakarerekē i waenganui i te wā, nā te meinga o ngā momo hangarau, ko te miro hāpuhia hoki i whakarerekētia - nei ki ngā pūtake me ngā hua e whakamahia ana kia tutuki ngā huringa hiahia mo te mahi pai me ngā kaupapa takitahi. Me whakaae he mea nui te whai i te momo e tika ana o te miro hāpuhia mo ngā hononga pai i runga i te hāpuhanga, ka whai ake he nui ki te oranga roa me te whakamahi pai o enei whakawae.
