Ina whakamahia e tātou te mata tātari mata roera, ina whakamahia mō te wā roa, ka tino paru te mata tātari mata roera, ā, me horoi, nō reira he tokomaha tonu te hunga kāore e mōhio ki te roera. Me pēhea te horoi i te tātari? Me titiro tātou me pēhea te horoi!

He puehu kei te mata o te mata tātari o te pahu, he ngāwari ki te tango i te paru. Ka taea te horoi ki te hopi, ki te horoi ngoikore, ki te wai mahana rānei. Tāpirihia he tapanga me te kiriata ki te mata o te kowiri tira, horoia ki te wai mahana, ki te hopi horoi ngoikore, ki ngā kai whakapiri, ka mirimiri ki te waipiro, ki ngā whakarewa rauropi rānei (ether, benzene). Ko te hinu, te hinu, me te hinu whakahinuhinu kei runga i te mata o te kowiri tira. Horoia ki te kakahu ngohengohe, kātahi ka horoia ki te otinga kūpapa, ki te otinga haukini rānei, ki te horoi motuhake rānei.

Ko ngā rauemi matua o te mata pahu ko te 304, 304L, 316, 316L, me ētahi atu. E whakamahia ana mō te tātari me te tātari i ngā taiao waikawa me te kawakore. E whakamahia ana te umanga hinu hei kupenga paru, e whakamahia ana ngā umanga matū me te muka matū hei mata, ā, e whakamahia ana te umanga whakakikorua hiko hei horoi waikawa.

He mā te wai me ngā waikawa rerekē kei te mata tātari pahu. Horoia tonutia ki te wai, kātahi ka rumakina ki te haukini, ki te wai houra waro koretake rānei, horoia ki te wai horoi koretake, ki te wai mahana rānei.

He āhua āniwaniwa te mata o te mata roera, nā te horoinga, te hinu rānei i puta ai. I muri i te horoinga ki te wai mahana, ka taea te horoi ki te horoinga koretake. Ka taea te horoi i te waikura i puta mai i te paru i runga i te mata o te kowiri tira ki te waikawa hauota 10%, ki ngā mea whakakoi rānei, ki ngā kaihoroi motuhake rānei.

He whānuitia te whakamahinga o te mata tātari pahu mō te tātari taiao nā te mea he ātete ki te wera, ki te waikawa, ki te kawakore, ki te pakū, ki te roa, ki te waikura, ki te roa hoki o te ora. Hei tauira, ka taea e ngā mata tātari kowiri tira e whakamahia ana i roto i ngā whare maimoatanga paru te tātari i ngā kōhatu, ngā paru, te tarutaru, te paru ora me ngā poke o te wai. He ngāwari te horoi i te mata roera, ā, ka taea te whakamahi i muri i te horoinga ki te wai. Nō reira, he rauemi tātari taiao tino pai.
