Mākete Waro Whakahohe

I te tau 2020, ko Āhia-Kiwa te whenua i pupuri i te wāhanga nui rawa atu o te mākete waro whakahohe o te ao. Ko Haina me Īnia ngā kaihanga matua e rua o te waro whakahohe o te ao. I Īnia, ko te umanga whakaputa waro whakahohe tētahi o ngā umanga tino tere te tipu. Ko te tipu haere o te ahumahi i tēnei rohe me te pikinga ake o ngā kaupapa a te kāwanatanga ki te rongoā i ngā para ahumahi i akiaki i te kai waro whakahohe. Ko te pikinga ake o te taupori me te nui o te tono mō te whakaputa ahumahi me te ahuwhenua te take o te tukunga o ngā para ki ngā rauemi wai. Nā te pikinga ake o te tono mō te wai i roto i ngā umanga e pā ana ki te whakaputa para, ka kitea te whakamahinga o te umanga maimoatanga wai i Āhia-Kiwa. He nui te whakamahinga o te waro whakahohe mō te purenga wai. E matapaetia ana ka whai wāhi atu tēnei ki te tipu o te mākete i te rohe.

Ka tukuna ngā tukunga mercury mai i ngā tipu hiko waro, ā, he mea kino ki te taiao me te hauora o te tangata. He maha ngā whenua kua whakatakoto ture mō te nui o ngā paitini e tukuna ana mai i ēnei tipu hiko. Kāore anō ngā whenua whakawhanake kia whakatū i ngā anga ture mō te mercury; heoi, ko te whakahaere mercury he mea hanga hei ārai i ngā tukunga kino. Kua mahi a Haina i ngā mahi hei ārai me te whakaiti i te parahanga e te mercury mā roto i ētahi aratohu, ture, me ētahi atu inenga. Ka whakamahia ngā hangarau whakahaere matatau, tae atu ki ngā taputapu me ngā pūmanawa, hei whakaiti i ngā tukunga mercury. Ko te waro whakahohe tētahi o ngā rauemi tino rongonui e whakamahia ana i roto i ngā taputapu o ēnei hangarau hei tātari i te hau. Kua piki ake ngā ture mō te whakahaere i ngā tukunga mercury hei ārai i ngā mate e puta mai ana i te paihana mercury i roto i te maha o ngā whenua. Hei tauira, i whakatinanahia e Hapani ngā kaupapa here pakari mō ngā tukunga mercury nā te mate Minamata i puta mai i te paihana mercury kino. Kua whakatinanahia ngā hangarau auaha, pērā i te Werohanga Waro Whakahohe, hei whakatika i ngā tukunga mercury i roto i ēnei whenua. Nō reira, ko te pikinga ake o ngā ture mō ngā tukunga mercury puta noa i te ao kei te akiaki i te hiahia mō te waro whakahohe.

E ai ki te momo, ka wehea te mākete waro whakahohe ki te paura, te kirikiri, me te kirikiri me ētahi atu. I te tau 2020, ko te wāhanga paura te mea nui rawa atu o te mākete. E mōhiotia ana te waro whakahohe i runga i te paura mō tōna whai huatanga me ōna āhuatanga, pērā i te rahi o te matūriki angiangi, e whakanui ana i te horahanga mata o te mimiti. Ko te rahi o te waro whakahohe paura kei roto i te awhe 5‒150Å. Ko te waro whakahohe paura te mea iti rawa te utu. Ko te pikinga o te kai o te waro whakahohe paura ka piki haere tonu te tono i roto i te wā matapae.

I runga i te tono, kua wehea te mākete waro whakahohe ki te maimoatanga wai, te kai me te inu, te rongoā, te motuka, me ētahi atu. I te tau 2020, ko te wāhanga maimoatanga wai te mea nui rawa atu o te mākete nā te pikinga ake o te ahumahi puta noa i te ao. Kei te whakamahia tonutia te waro whakahohe hei reo tātari wai. Ka poke te wai e whakamahia ana i roto i te hanga, ā, me maimoatanga i mua i te tukunga ki ngā wai. He maha ngā whenua he ture tino pakari mō te maimoatanga wai me te tukunga o te wai poke. Nā te kaha nui o te waro whakahohe i puta mai i tōna porosity me te horahanga mata nui, he whānui te whakamahinga hei tango i ngā poke i roto i te wai.

He maha ngā whenua e whakawhirinaki ana ki ngā kawemai o ēnei rauemi mata hei whakarite i te waro whakahohe, i pāngia e ngā wero nui i te hoko mai i ngā rauemi. Nā tēnei i kati katoa, i kati rānei ngā wāhi hanga waro whakahohe. Heoi, i te mea e whakamahere ana ngā ōhanga ki te whakaora anō i ā rātou mahi, e matapaetia ana ka piki ake te hiahia mō te waro whakahohe puta noa i te ao. Ko te piki haere o te hiahia mō te waro whakahohe me ngā haumitanga nui a ngā kaihanga rongonui ki te whakanui ake i te kaha whakaputa e matapaetia ana ka akiaki i te tipu o te waro whakahohe i roto i te wā matapae.
