Kei te piki haere te aro o te marea me te hapori pūtaiao ki tētahi matū e whakamahia whānuitia ana i roto i ngā mara maha o te ahumahi me te oranga o ia rā.
I. 4,4′ – DIHYDROXYDIPHENYLMETHANEHe whānuitia ngā whakamahinga. I roto i te ao ahumahi, ko te 4,4′ – DIHYDROXYDIPHENYLMETHANE he rauemi mata matua mō te hanga kapia epoxy mahi-teitei. He whānuitia te whakamahinga o tēnei momo kapia epoxy i roto i ngā ahumahi hikohiko me ngā taputapu hiko. Hei tauira, i roto i te tukanga hanga o ngā papa ara iahiko tā (PCB), ka taea e ngā kapia epoxy momo 4,4′ – DIHYDROXYDIPHENYLMETHANE, me ō rātou āhuatanga hiko, ātete miihini me te wera pai, te whakarite i te mahi pumau o ngā wāhanga hiko i roto i ngā taiao mahi uaua. I roto i te umanga hanga, he mahi nui anō hoki tā ngā rauemi kei roto ko te 4,4′ – DIHYDROXYDIPHENYLMETHANE. Ka whakamahia ēnei hei hanga paninga me ngā piripiri mahi-teitei, ka taea te whakarato i te roa me te piri pai, ka pai ake te pumau o te hanganga o te whare, ā, ka roa ake te tiaki i te taha o waho o te whare. Hei tāpiri, kei te puta ake hoki te 4,4′ – DIHYDROXYDIPHENYLMETHANE i roto i ngā ahumahi hanga-teitei pēnei i te hanga motuka me te rererangi. Hei tauira, i roto i te tiakitanga paninga o ngā wāhanga motuka me te hononga hanganga o ngā taputapu rererangi, kua whai wāhi te 4,4′ – DIHYDROXYDIPHENYLMETHANE ki te whakapai ake i te mahi a te hua.
II. Ka ara ake ngā āwangawanga mō ngā mōrearea hauora. Heoi, i te hohonu haere o ngā rangahau, kua tīmata te whakaoho i te mataara o te tangata ki ngā mōrearea hauora pea o te 4,4′ – DIHYDROXYDIPHENYLMETHANE. He maha ngā rangahau pūtaiao kua whakaatu he rite tonu ngā āhuatanga endocrine – whakararuraru o te 4,4′ – DIHYDROXYDIPHENYLMETHANE ki te 4,4′ – DIHYDROXYDIPHENYLMETHANE (BPA). Ka taea e ngā mea whakararuraru endocrine te whakararuraru i te pūnaha endocrine tangata, ā, ka pā ki te huna noa me ngā mahi whakahaere o ngā homoni. Kua whakaatuhia e ētahi whakamātautau kararehe ko ngā kararehe whakamātautau e pāngia ana e te taiao 4,4′ – DIHYDROXYDIPHENYLMETHANE tera pea he whanaketanga rerekē o te pūnaha whakaputa uri, he ngoikore o te tairoi me ētahi atu āhuatanga. Ahakoa kāore anō kia kitea he taunakitanga tika mō te tangata i tēnei wā, i runga i ngā āwangawanga hauora i puta mai i te 4,4′ – DIHYDROXYDIPHENYLMETHANE me te ōrite o ngā hanganga matū o te 4,4′ – DIHYDROXYDIPHENYLMETHANE me te 4,4′ – DIHYDROXYDIPHENYLMETHANE, kāore e taea te whakaiti i tēnei mōrearea pea.
III. Te tirotiro me ngā mahi ārai. I runga i ngā tūponotanga hauora pea o te 4,4′DIHYDROXYDIPHENYLMETHANE, kua tīmata ētahi whenua me ngā rohe ki te whakahaere i tēnei. Kei te whakatakoto ngā tari e tika ana i ngā paerewa taiao me ngā paerewa haumaru hua kia kaha ake ai te whakamahi i te 4,4′ – DIHYDROXYDIPHENYLMETHANE i roto i ētahi hua ka pā tata pea ki te tinana tangata. I te taha hinonga, kei te kaha hoki ētahi hinonga matū me ngā hinonga tono i raro iho ki te tūhura i ngā huarahi kē atu i te 4,4′ – DIHYDROXYDIPHENYLMETHANE, inā koa i roto i ngā mara he tino teitei ngā whakaritenga haumaru pērā i te takai kai me ngā hua tamariki. Kei te whai ngā kaimahi R & D ki te kimi rauemi hou ka taea te whakatutuki i ngā whakaritenga mahi hua me te whakarite kia pai ki te hauora tangata me te taiao. He mahi nui tā te 4,4′ – DIHYDROXYDIPHENYLMETHANE i roto i te whanaketanga ahumahi, engari me tino aro atu ki ōna tūponotanga hauora. Mā te hohonu haere tonu o te rangahau pūtaiao me te whakapai haere i ngā tikanga ture, e tūmanakohia ana ka taea te whakaiti i ngā kino ka pā ki te hauora tangata me te taiao, ahakoa te whakamahi i ōna painga.
