Ka awhi te umanga whakakikorua hiko i te auahatanga hangarau, ka whakanui ake i te tiaki taiao me te whai huatanga

Nō nā tata nei, kua kitea e te umanga whakakikorua hiko he raupapa o ngā auahatanga hangarau, me te whakauru mai o ētahi kamupene i ngā tukanga whakakikorua hiko hou e aro ana ki te taiao, e aro ana ki te whakaiti i te parahanga taiao me te whakapai ake i te pai o te whakaputa. Hei hangarau maimoatanga mata e whakamahia whānuitia ana i roto i ngā ahumahi pēnei i te motuka, te hikohiko, me te rererangi, ko te pai o te whakakikorua hiko te kaupapa matua o te aro nui.

I roto i ngā tukanga whakakikoruatanga hiko tuku iho, ka whakamahia pinepinetia ngā matū paitini pēnei i te cyanides me te hexavalent chromium, e kore anake e tūpono ki te hauora o ngā kaiwhakahaere engari ka puta hoki he parahanga nui ki te taiao. Nā te kaha haere o ngā ture taiao o te ao, kei raro i te pēhanga nui te umanga whakakikoruatanga hiko ki te huri. Hei whakautu, he maha ngā kamupene kua tīmata ki te whakawhanake me te whakatairanga i ngā hangarau hoa-taiao pēnei i te whakakikoruatanga hiko kore-cyanide me te whakakikoruatanga hiko chromium trivalent.

E ai ki ngā pūrongo, i whakarewahia e tētahi kaihanga taputapu whakakikorua hiko rongonui tētahi momo otinga whakakikorua hiko hou kāore he cyanide. Ka whakakapia e tēnei otinga ngā cyanide tuku iho ki ngā matū waro, ka whakaitihia te paitini me te whakapai ake i te ōritetanga me te piri o te paparanga whakakikorua. Hei tāpiri, kei te whakakapi haere te hangarau whakakikorua hiko chromium trivalent i te whakakikorua hiko chromium hexavalent tuku iho. He iti ake te paitini o te chromium trivalent i te chromium hexavalent, ā, he māmā ake te tukatuka wai para, e hangai ana ki ngā whakaritenga taiao o ēnei rā.

Haunga ngā putanga hou o ngā hangarau e pai ana ki te taiao, kua tino kitea hoki te ahunga whakamua o te umanga whakakikorua hiko i roto i te whakaputa atamai. I whakauruhia e tētahi kamupene whakakikorua hiko tētahi raina whakaputa whakakikorua hiko aunoa katoa, e tutuki ai te aunoatanga mai i te maimoatanga o mua ki te whakakikorua hiko me te maimoatanga o muri mā roto i ngā mahi karetao me ngā pūnaha whakahaere atamai. Ehara i te mea ka whakaitihia noa ngā hapa tangata engari ka whakapai ake hoki i te pai o te whakaputa me te whakaiti i ngā utu.

E ai ki te kamupene, "Ehara i te mea ka whakarei ake te whakaputa atamai i te kounga pumau o ngā hua kua whakakikoruatia ki te hiko, engari ka whakaitihia hoki te para o te pūngao me ngā rauemi mata, e hangai ana ki te ariā o te whanaketanga tauwhiro."

I ngā tau tata nei, kua whakaurua e ngā kāwanatanga o te ao ngā kaupapa here e whakatenatena ana i te umanga whakakikorua hiko kia anga whakamua ki te whanaketanga matomato me te mohio ake. Hei tauira, ko te Mahere Tau Rima 14 o Haina mō te Whanaketanga Kakariki Ahumahi e kī ana kia whakatairangahia te whakaputanga ma i roto i te umanga whakakikorua hiko me te whakatairanga i ngā hangarau pēnei i te whakakikorua hiko kore-cyanide me te iti-paitini. Kua whakatakotoria hoki e te Kotahitanga o Ūropi ngā here tino kaha ki te whakamahinga o ngā matū morearea i roto i te umanga whakakikorua hiko mā te ture REACH.

E whakapono ana ngā tāngata o roto i te umanga, nā te whanaketanga tonu o ngā kaupapa here taiao me te ahunga whakamua hangarau, kei te uru te umanga whakakikorua hiko ki tētahi wāhanga whanaketanga matomato me te whai hua. I ngā rā kei te heke mai, ehara i te mea me auaha noa ngā kamupene whakakikorua hiko i te hangarau engari me whakapakari hoki i te mahi tahi puta noa i te mekameka umanga hei whakatairanga tahi i te whanaketanga pumau.

Kei te werohia e ngā auahatanga hangarau i roto i te umanga whakakikorua hiko he kaha hou ki te hanga o te ao. Mā te whakatairanga i ngā tukanga whakakikorua hiko e pai ana ki te taiao me te whakamahi i te whakaputa atamai, ehara i te mea ka āwhina noa i te whakaiti i te parahanga taiao, engari ka whakarei ake hoki i te kounga o te hua me te whai huatanga o te whakaputa. Mā te tautoko kaupapa here me ngā whanaketanga hangarau, kua rite te umanga whakakikorua hiko ki te whakatutuki i te whanaketanga matomato me te atamai ake i te heke mai.
