I roto i te ao o ngā pūtake hiko kawe, kua roa ngā pākahiko kawakore e noho hei mea nui nā te mea he pono, he whai hua hoki. Heoi, nā te tipu haere o ngā āwangawanga taiao me ngā ture pakari ake, kua tohu te whanaketanga o ngā pākahiko kawakore kore-mercury me te cadmium i tētahi ahunga whakamua nui ki ngā otinga hiko haumaru ake, pumau ake hoki. Ka rukuhia e tēnei tuhinga ngā painga maha o te tango i ēnei huarahi rerekē e pai ana ki te taiao, me te whakanui i ō rātou painga taiao, hauora, mahi, me te ōhanga.
**Te Oranga Taiao:**
Ko tētahi o ngā painga nui o ngā pākahiko kawakore kore-mercury me te cadmium ko te iti o te pānga ki te taiao. He maha ngā wā kei roto i ngā pākahiko kawakore tuku iho te mercury, he konganuku taumaha paitini, ā, ki te kore e tika te whakakore, ka poke pea i te oneone me ngā awa, ka tū hei mōrearea ki ngā kararehe mohoao me ngā rauropi. Waihoki, ko te cadmium, tētahi atu matū paitini e kitea ana i roto i ētahi pākahiko, he matū carcinogen e mōhiotia ana ka pā kino ki te hauora o te tangata me te taiao. Mā te whakakore i ēnei matū, ka tino whakaitihia e ngā kaihanga te mōrearea o te parahanga me te hono atu ki ngā mahi a te ao ki te hoahoa hua e pai ana ki te taiao.

**Ngā Āhuatanga Mahi Whakapai Ake:**
He rerekē ki ngā āwangawanga tuatahi mō te tango i te mercury ka pā kino ki te mahi a te pākahiko, nā ngā whanaketanga hangarau kua taea e ngā pākahiko kawakore-mercury me te cadmium te pupuri, ki te kore e hipa ake, i ngā taumata mahi a ō rātou mua. He nui te kaha o ēnei pākahiko, e whakarite ana i te roa o te wā e mahi ana mō ngā taputapu e hiahia ana ki te hiko. Nā tō rātou kaha ki te whakarato putanga ngaohiko pumau puta noa i te whānuitanga o ngā pāmahana me ngā kawenga, he pai mō ngā tono maha, mai i ngā mana mamao ki ngā taputapu e tere te mimiti pērā i ngā kāmera mamati. Hei tāpiri, he pai ake te ātete ki te turuturu, e whakarite ana i te haumaru me te roa o te wā o te taputapu.
**Whakatutukitanga ā-Ōhanga me ngā Ture:**
He hua ōhanga anō hoki te whakamahi i ngā pākahiko kawakore kore-mercury me te cadmium. Ahakoa he rite tonu, he paku teitei ake rānei ngā utu hoko tuatahi, ko te roa o te ora o ēnei pākahiko ka iti ake te utu mō ia whakamahinga. Me iti ake te maha o ngā whakakapinga pākahiko a ngā kaiwhakamahi, ka whakaiti i ngā whakapaunga me ngā para. Heoi anō, mā te whai i ngā ture o te ao pērā i te ture RoHS (Restriction of Hazardous Substances) a te EU me ngā ture rite puta noa i te ao ka taea te hokohoko i ngā hua e whakamahi ana i ēnei pākahiko puta noa i te ao me te kore he arai ture, ka whakatuwhera ake i ngā whai wāhitanga arumoni whānui ake.
**Te Whakatairanga i te Hangarua me te Ōhanga Porowhita:**
Ko te nekehanga ki ngā pākahiko kawakore kore-mercury me te cadmium ka akiaki i ngā kaupapa hangarua. I te mea ka pai ake te taiao o ēnei pākahiko, ka haumaru ake, ka māmā ake te hangarua, ka whakatairanga i te ōhanga porowhita ka taea te whakaora me te whakamahi anō i ngā rauemi. Ehara i te mea ka tiakina noa ngā rauemi taiao engari ka whakaitihia hoki te whakawhirinaki ki te tango rauemi mata, ka whai wāhi atu ki ngā whāinga pumau.
Hei whakamutunga, ko te nekehanga ki ngā pākahiko kawakore kore-mercury me te cadmium he taahiraa nui i roto i te whanaketanga o te hiko kawe. Kei roto i ēnei pākahiko he ranunga maeneene o te auahatanga hangarau, te kawenga taiao, te tiaki hauora tūmatanui, me te mahi ōhanga. I a mātou e haere tonu ana ki te whakatere i ngā wero o te whakataurite i ngā hiahia pūngao me te tiaki taiao, ko te whānui o te whakamahinga o ēnei pākahiko hoa-taiao he tohu i tō mātou whakapau kaha ki tētahi heke mai ma, hauora, me te pumau.
