Nō nā tata nei, kua tīmata mana te pōtitanga perehitini i Djibouti. Whai muri i te pōti, ka whakaatu whakahīhī ngā kaipōti i ō rātou maihao kua tohua ki te mangumangu pōtitanga—he tirohanga noa engari he mea pārekareka ki ngā teihana pōti puta noa i te motu. Ahakoa te āhua noa, e whakamahia ana tēnei mangumangu motuhake i roto i te neke atu i te 100 whenua o te ao hei tiaki i te pono o ngā pōtitanga. Mā te tohu kotahi noa i te pito o te maihao, ka mau tonu te tika me te mana o ngā pōtitanga manapori.
Ko te waituhi pōtitanga, e mōhiotia ana ko te waituhi pumau, he mea hanga nui mai i te hiriwa nitrate.
Waituhi pōtitanga, e mōhiotia ana ko te waituhi pumau, he hiriwa nitrate te nuinga o te wā.
Kia pania ki te ringaringa, kia kitea hoki ki te hihi ultraviolet, ka waiho he tohu tuturu ki te kiri me ngā maikuku e kore e taea te horoi atu mā te horoi noa. Ka memeha haere te tohu i te mea ka whakahoutia te kiri, ka tupu ake ngā maikuku, he tukanga e roa ana mō ētahi wiki, mō ētahi marama rānei.
Ka mau te tohu mō ngā marama, ā, e kore e memeha.
I te tau 1962 anō i whakamahia tuatahitia ai tēnei momo waituhi i roto i te pōtitanga whānui o Īnia. Nā te National Physical Laboratory o Īnia i whakawhanake, ā, kua kaweakehia inaianei ki ngā whenua neke atu i te 30, ā, kua waiho hei taputapu nui hei ārai i te tinihanga mō ngā pōtitanga.
I ngā teihana pōti, ka pania e ngā kaimahi pōti te mangumangu kia ōrite ki ngā maihao tohu, ki ngā maihao iti rānei o ngā pōti, kia kapi ai te whao me te moenga whao. Mā tēnei ka ārai i te tinihanga pōtitanga pērā i te pōti maha me te pōti māngai.
I whakaratohia e te Kaupapa Whakawhanake o te Kotahitanga o ngā Whenua o te Ao he 113,000 pounamu pōtiwaituhimō te pōtitanga whānui o Myanmar i te tau 2020. Whai muri i te whakamātautau pakari, i tutuki katoa te nui o te hiriwa nitrate i roto i ēnei waituhi i ngā paerewa o te ao. Ahakoa i horoia tonutia ki te hopi me te wai horoi ringa kei roto i te waipiro, i noho mārama tonu ngā tohu, ā, kāore i pakaru.
I whakamahia tuatahitia tēnei waituhi i te pōtitanga whānui o Īnia i te tau 1962.
I te whanaketanga tonu o te hangarau, kua whakahoutia tonutia hoki te waituhi pōti. I ēnei rā, kei te wātea ngā hua e whakaatu ana i ngā tae e kitea ana i raro i te mārama noa, engari he āhuatanga ārai-tītaha hoki.
E kitea mārama ana te tohu i raro i te mārama noa, ā, ina whakamāramahia ki te rama ultraviolet, ka puta he tauira motuhake e whakaatu ana i ngā pānga ārai-tinihanga kua whakarei ake. Kāore he paitini o te waituhi, kāore he kino ki te tinana tangata, ā, he pai ake ki te taiao. Ehara i te mea he taputapu noa iho tēnei pounamu waituhi hei ārai i te tinihanga pōti—he "mētara" anō hoki mō ngā pōti e whakamahi ana i ō rātou mana manapori, e whakaatu ana i ngā wawata a te marea mō te tika me te tika.
Mai i Āhia ki Āwherika, ahakoa i roto i ngā pōtitanga perehitini, i ngā pōtitanga ā-rohe rānei, ka tiakina e te mangumangu pōti te pono o ia pōti nā te mea he māmā, he whai hua, he iti hoki te utu. Ehara i te mea ko taua tohu iti i runga i te pito o te matihao anake e whakaata ana i te mana o te manapori engari he tohu hoki mō te whai a te ao i ngā pōtitanga tika, ka waiho hei tohu whakawhiti-rohe mō te manapori.
E tata ana ki te 20 tau o te wheako motuhake o OBOOC ki te whakarato i te mangumangu pōtitanga.
Hei kaiwhakarato ngaio mō ngā taputapu pōti, ko Aobozmangumangu pōtikua riro i a ia te whakawhirinakitanga whānui o te mākete mō tōna haumaru teitei, tōna pakari kaha me tōna mahi ārai-tītaha pai rawa atu.
Mō ngā wheako tuku, kua neke atu i te 20 tau te waitohu e whai wāhi nui ana ki te umanga me te kaha kua kohia. Kua whakaratohia e ia ngā otinga waituhi ritenga mō ngā pōtitanga nui pēnei i ngā pōtitanga perehitini me ngā pōtitanga kāwana i roto i te neke atu i te 30 whenua puta noa i Āhia me Āwherika, me te whakamanamana i te nui o ngā wheako ratonga mahi.
Mō te mahi a te hua, he tino kitea ngā painga matua: i tētahi taha, ka whakamahia te hangarau matūriki nano-hiriwa, e tino whakapai ake ana i te ōritetanga o te waituhi me te piri o te kiri. He uaua te tango i te tohu mā te whakamahi i ngā kaihoroi noa, ā, he pumau te whanaketanga o te tae, ā, ka roa mō te 3 ki te 30 rā. I tētahi atu taha, he tere te whakamaroke. I muri i te paninga ki te kiri, ki ngā whao rānei, ka maroke i roto i te 10 ki te 20 hēkona noa iho, ā, ka huri hei parauri pouri mārama i muri i te waikura, e kore e ārai noa i te paru me te pōuri o te tohu, engari ka whakaiti hoki i te tūponotanga o te poke whakawhiti.
Ko te waituhi pōtitanga, e mōhiotia ana ko te waituhi pumau, he mea hanga nui mai i te hiriwa nitrate.
