E tutuki ana i ngā paerewa taiao o te ao pēnei i te RoHS me te REACH, kāore he kakara, he toenga matū kino rānei; he iti te nui o te tāpiri (0.1%-0.5% hei whakatutuki i ngā hua tino pai), e whakaiti ana i ngā utu ārai-pakeketanga me te whakanui ake i te uara tāpiri hua me te whakarei ake i te whakataetae mākete.
4. Parenga Whānui-Awhe, He pai mō ngā Kirihou Maha-Hotaka
E kapi whānuitia ana ngā āhuatanga tono kirihou, mai i ngā paipa kirihou o waho, ngā ārai rā, me ngā whakaurunga whakangahau ki ngā wāhanga o roto me waho o ngā motuka, ngā anga taputapu kāinga, me ngā kiriata takai kai, e whakarato ana i ngā otinga kotahi-mutu mō ngā hiahia ārai-pakeketanga.
Te Waihanga i ngā Hua Kirihou Kounga-Teitei me Koe
Ko te whiriwhiri i te dibenzoylmethane ehara i te mea ko te tāpiri noa i te mea mimiti hihi ultraviolet, engari ko te werohanga hoki i ngā ira tiaki roa ki roto i te hua — te whakapai ake i te pakari, te whakaiti i ngā mate i muri i te hoko, me te whakarei ake i te whakawhirinaki o ngā kiritaki. Ka whakaratohia e mātou he tauira kore utu, he tautoko hangarau, me ngā mahere tāpiri kua whakaritea kia rite ki tō momo kirihou me tō horopaki tono, hei āwhina i ō hua kia tū motuhake i roto i te mākete kaha!
