Ngā kirimi whakama, ngā kopare kanohi, ngā hinu tiaki kiri, ngā tae makawe… I ēnei rā, he whānuitanga o ngā hua whakapaipai kei te mākete, ā, kei te puta haere tonu mai, e tino manakohia ana e te hunga aroha ki ngā mea ataahua. Heoi, i te tīmatanga, ko ngā mea whakapaipai i whakamahia hei tiaki kiri, hei whakapaipai, hei horoi hoki i te tinana tangata. Heoi, ko te haumaru o ngā mea whakapaipai te mea nui ake i te whai huatanga. Ki te kore, ina pā te tinana tangata ki ngā mea whakapaipai ngoikore, ka puta pea ngā tūponotanga tinana me te hinengaro pērā i te mate pāwera, te ngaro o te makawe, te whakapōrearea, me te mate pukupuku.

Nā tēnei, he maha ngā tari R&D me ngā taiwhanga e hono ana ki ngā tari tirotiro kounga o ngā kamupene whakapaipai ka whakamātautau i ngā kai o ngā rauemi mata o ngā hua whakapaipai, ngā rauemi takai, ngā hua haurua-oti, me ngā hua kua oti. I muri i te aromatawai i te kounga me te haumaru i runga i ngā paerewa whakahaere kounga e tika ana ka taea te whakaputa i tētahi tiwhikete tohu hua. Ka kitea ko te tautuhi me te whakamātautau i ngā whakapaipai i roto i te taiwhanga kua waiho hei arai tuatahi ki te tiaki i te hauora me te haumaru o ngā kaihoko.
Nā, he aha ngā kaupapa matua o ngā whakamātautau haumaru whakapaipai?

I roto i tētahi kaihanga whakapaipai noa, he mea noa ake te whakamātautau konganuku taumaha, te whakamātautau moroiti, te whakamātautau tiaki, te whakamātautau ihirangi matū hohe, me ētahi atu matū kua rāhuitia, kua herea hoki i roto i ngā whakamātautau paitini me ngā tūemi tātari paitini. Hei tauira, ko te konukōre konukōre taumaha te konukōre iti: kāore te konukōre, te waikawa konukōre, te konukōre konganuku, me te konukōre hexavalent e kitea tika ana i roto i ngā whakapaipai. Heoi, i roto i te tukanga whakaputa me te whakawhanaketanga o ngā whakapaipai, kei roto i ngā ipu karāhe ngā matū poke kei roto te konukōre, pērā i te Cr6+. Me mahi ngā taiwhanga i te whakatau me te tātari, kātahi ka whakatakoto i ngā otinga.

Heoi, kāore i mutu i konei te haerenga whakamātautau kounga me te haumaru o ngā mea whakapaipai i roto i te taiwhanga.

Ko te arai tuarua e pā ana ki ngā kamupene whakapaipai ko te tirotiro matapōkere a ngā tari tirotiro ā-motu e tika ana i ngā whakapaipai kua horapa hei whakarite i te whanaketanga hauora me te tika o te mākete. Hei tauira, mēnā kei runga ake i te paerewa te mata, te āheniki, te mercury, te maha o ngā koroni huakita, te p-phenylenediamine, ngā tae marara, me ētahi atu i roto i ngā hua whakapaipai, mēnā rānei kei roto i ngā matū kua rāhuitia pērā i te meta-phenylenediamine me te phthalates. I ētahi wā ka tukuna atu ēnei mahi whakamātautau ki ngā taiwhanga o ngā whare whakamātautau tuatoru. Waihoki, me whakaū tēnei mā roto i ngā whakamātautau tauira i mua i te tukunga o te pūrongo tirotiro kounga ki ngā kamupene whakapaipai me ā rātou hua i runga anō i ngā tikanga ture.

Ehara i te mea uaua ki te whakaaro ko te whiwhi i te painga tuatahi i roto i te whakataetae nui o te mākete, i te mea kei te piki haere tonu te auau hou o te rangahau me te whanaketanga o ngā kamupene whakapaipai, ko te tikanga ka piki ake hoki te kawenga mahi o te taiwhanga.

Heoi, ahakoa he taiwhanga o tētahi kamupene whakapaipai, he taiwhanga o tētahi tari kāwanatanga, he taiwhanga whakamātautau tuatoru rānei, he tino uaua te mahi whakamātautau whakapaipai, ā, he mea nui kia whakanuia te maha o ngā taputapu whakamātautau kia pai ake ai te whai huatanga. Ina koa kia tika ai ngā hua o te whakamātautau, me whakatau tuatahi te ma o ngā karāhe i whakamahia i roto i te whakamātautau. I te aroaro o tēnei wero, ko te mahi ahoroi karaihe taiwhangakua nui haere te hiranga. Nā te mea ko tehoroi karaihe aunoae kore e taea anake te whakarato i te horoinga nui, atamai me te tino tika o ngā poke mō ngā oko karaihe taiwhanga, engari he haumaru ake, he pai ake hoki mō te taiao i te wā e whakamahia ana. Ka taea hoki e ngā raraunga e tika ana kua tuhia te āwhina ki te whakarato i tētahi tohutoro whai hua i te wā e whakamātautau ana i te kounga o ngā mea whakapaipai.

Kaua e tukua te atawhai kia whara. Whakakorea te tāpiri turekore o ngā matū kua rāhuitia me ngā matū kua herea, ā, kia whakarite kia pūtaiao, kia pumau, kia whai hua hoki ngā hua whakapaipai. E pā ana tēnei ki ngā tika me te haumaru o ngā kaihoko, ā, koinei te wāhi e tutuki ai i ngā kaihanga me ngā kaiwhakahaere ā rātou herenga me ā rātou kawenga. Ko te kī ki te haumaru o ngā whakapaipai e whakawhirinaki ana ki te tika o ngā hua whakamātautau taiwhanga. Mā te whiwhi i ngā tātaritanga whakamātautau me ngā whakatau tūturu ka taea ai e tātou te whai wāhi pono.
