mita hau wai me te kaiwhakauru
Ko te metara oksinita kua wehe me te kaiwhakauru he taputapu whai hua e whakamahia ana hei ine i te kaha o ngā molekīni oksinita kua pouri ki ngā wai. Ko tēnei taputapu hahonu te kaiwhakauru i ngā hangarau whakamātau anō hoki ki te whakarato inenga tika, mōhio e mōhio ana i ngā taumata oksinita ki ngā taiao wai rereke. Ko te tūhononga heke ki ngā waahanga e rua matua: ko tētahi metara mātāpuna e whakaatu ana i ngā inenga me te tukatuka i ngā raraunga, me tētahi kaiwhakauru motuhake e kite ana i ngā molekīni oksinita ki te whakaputanga. Ko te kaiwhakauru e whakamahi ana i te hangarau electrochemical, optical rānei hei ine i ngā taumata oksinita kua wehe, ā, ko ngā putanga hou e whakauru ana i te tautohenga wera hei whakapai ake i te tika. Ka taea e ngā taputapu e ine i te oksinita kua wehe ki te 'parts per million' (ppm) me te ōrau tōtara hoki, e tuku ana i te whakauru mō ngā whakamahinga rereke. Ko te hangarau e whakamahi ana i ngā paparorohia matua e whakaae ana i ngā molekīni oksinita kia tūhono atu kia herea atu ana i ētahi atu mea, e tiakina ai te tika o ngā inenga hoki ki ngā tikanga uaua. Ko ngā whakamahinga e kaweni ana i te maha o ngā umanga, tae atu ki te whakahaere wai parurenga, te tāwhai wai, te whakauru ki te taiao, me te whakaputa rongoā. E whakarato ana ngā metara i ngā raraunga matua hei whakauru i ngā taumata oksinita tino pai ki ngā mahi e kōhikohi ana mai i te whakamātau i te whakaputanga wai ki te whakāhua i te taiao wai. Ko ngā metara oksinita kua wehe hou e whakauru ana i ngā āhua atu pērā i te tāpiri raraunga, te hononga irirangi, me te tūhono ki ngā tūhononga whakauru ake, e hauāngia ai i ngā taputapu matua ki te tariu kounga me te whakapai ake i te mahi.
