Te mārama ki te Sulfur Dioxide (SO2): Ngā āhuatanga, Whakamahinga, me te Whaitua ki te Taiao

Sulfur dioxide (SO2) ko tētahi o ngā oksīti rino tōrino me te māmā, i te mōhiotia e tana whakaaturanga matū, SO2. Ko tēnei kāhau kāore he tae, he whakapāhunu hoki tana, e whakapāhunu ai i tana arataki ki ngā horonuku hāngai ki te ahumahi. Hei tākarotia ana te rino dioksīti ki te wai, te inu miraka, me te ēteri, e whakapīrangi ai i tana whakahaerenga ki ngā tikanga haukaha me te ahumahi. Nā te nui o tana painga ki te taiao, he tino kaiwhakawehi hoki te rino dioksīti ki te hau noho o te ao.

Ko ngā putanga ake o te taramea (sulfur dioxide) e hāngai ana ki ngā rū whenua, i reira i ngā wā katoa ka whakaputua te nuinga o tēnei kāpua ki te takotoranga. Heoi anō, ko tētahi wāhanga nui o ngā putanga taramea he hononga ki ngā mahi a te tangata, ā, he tino pā ki ngā mahi hāpai. Ko te kaiwhakarewa (combustion) o te hīāhua (coal) me te hinu (oil), e taramea hoki, ka hua mai i te putanga taramea. Ina parurewa ki te wai, ka pāngia te taramea hei hanga i te sulfite (H2SO3), he matua tīmatanga nui ki ngā mea whakaru. Ki te āhua o te paraihe PM2.5, ka taea e te sulfite te oxi (oxidize) marino hei hanga i te haurangi taramea, ko te kaiaro tino o te ua whakaru. Whakatairitea tēnei huringa i ngā aronga taiao e hāngai ana ki te whakamahi i ngā kora hinu taramea.

Ngā Whakamahinga Matua o te Taramea

Ko te taramea he kaiwhakarewa āhua whānui e whai wāhi ana ki ngā tini umanga:

1. Kaiwhakapai Kaiwhakarewa me te Kaitakaro: Ko te raru raihana te kaiwhakapai pai me te kaitakaro raihana, e hāpai ana i te whakapai ake i te maha o ngā hinu whakapai.

2. Whanaketanga Matū: Ko tētahi o ngā whakamahinga matua o te raru raihana ko te whanaketanga o te raru raihana (SO3), te raru raihana (H2SO4), ngā kōaro raru, me ngā thiosulfates. I tua atu, ka whakahaere kaiwhakarupeke, kaiwhakapūmau, kaiwhakamaru, me te kaiwhakaiti.

3. Tari Kai: I Tiamatia, kei te whakaaetia te raru raihana hei kaiwhakaiti whakaputonu, ina hau te rite ki te tukatuka kai. He whakaputonga whakapai ake āna me te whakaiti i ngā eneima oksihana i ngā kai hua parakore. Ko ngā tikanga here here e whakaaetia ana tana whakamahinga ki te whanaketanga wīra me te wīra hua, me te tepe raihana raihana o 0.25 grama ia kilogram me te tohu here here e kaua e nui ake i te 0.05 grama ia kilogram.

4. Ahuwhenua me te Whakapakoko: Kei waho i te ahumahi kai, kei te whakamahia te dioksinita o te kōhuri ki te whakapakupeke i ngā peita, ngā whītau ranei, ngā kairua, me ētahi atu kikorangi hoki.

5. Te Whakahaerenga Karawhiti: Ko tana tūranga hei peita karawhiti me te whakamāmā i ngā pātai hoki e whakapumau ai i te nui o te dioksinita kōhuri ki ngā tāone ahumahi me ngā tāone whakapakoko, e tūhono ana hei taputapu matua mō te whakahaerenga karawhiti.

Whakamutunga

Ahakoa kei te noho pūmau te dioksinita kōhuri (dioksinita kōhuri) ki ngā whakamahinga whakapakoko maha, kāore i te tirohanga ki ana pānga ki te taiao. Mei te kaiwhakauru matua ki te āhua, ki te whakamahinga, ki ngā pānga hoki o te dioksinita kōhuri he mea nui kia mōhio ngā kaitirotiro me ngā tāone e whai whakapakoko ana ki tēnei kikorangi. Me ngā whakatinanaga me ngā whakapai ake kia iti ake ngā pānga taiao kino e hāngai ana ki te dioksinita kōhuri, kia tū tonu ai te aronga ki tana whakamahinga.
