Ko te Formaldehyde (HCHO) he matū waro kore tae, he kaha te kanga, he hau e memeha ana i te pāmahana rūma, ā, he ngāwari ki te wairewa i roto i te wai. He takawaenga nui i roto i te maha o ngā mahi whakaputa ahumahi me ngā tukanga pākia koiora, e whakamahia whānuitia ana i roto i ngā mara e whai ake nei: ngā kapia hangai (pēnei i ngā kapia urea formaldehyde, ngā kapia phenolic), ngā piripiri, ngā kirihou, ngā kaihoko whakaoti kakahu, me ētahi atu.
E ai ki te World Health Organization (WHO) me te International Agency for Research on Cancer (IARC), kua whakarōpūtia te Formaldehyde hei matū whakaputa mate pukupuku Rōpū 1 (he tino kitea te kaha whakaputa mate pukupuku ki te tangata), ā, ko ōna tūponotanga ka kitea nuitia i roto i:
①Te pānga poto:
Te riri: Ka puta te whero me te pupuhi o ngā kanohi mēnā ka pā tika atu ki te kiri, te wera o te korokoro, te mate pāwera kiri, me ētahi atu.
Ngā tohu manawa: ka maremare, ka kikī te uma, ka kaha ake te mate huango, me ētahi atu.
②Te pānga roa:
Mōrearea mate pukupuku: Ka pā mai pea te mate pukupuku i te waha o te ihu, te leukemia, me ētahi atu i te manawa roa o te formaldehyde.
Te paitini mau tonu: ka kino te pūnaha ārai mate, te pūnaha io, ā, he tino kino ki ngā wāhine hāpu, ki ngā tamariki me ngā kaumātua.
Ka whakamahia tā mātou Aldehyde Scavenger hei tango i ngā toenga formaldehyde me te acetaldehyde mai i ngā polymers,he tino pai mō te tango i te acetaldehyde mai i te PET hei whakatutuki i ngā whakaritenga o te takai kai me te inuHe pai hoki mō te tango i te formaldehyde me te acetaldehyde mai i ngā kapia acetate, ngā piripiri, me ngā paninga peita.
He rauemi e whakamahia whānuitia ana te PET (polyethylene terephthalate) mō ngā pounamu inu. I roto i te ariā, kāore he formaldehyde i roto i te PET parakore, engari ko ngā āhuatanga e whai ake nei ka hua ake he iti noa te formaldehyde kei roto:
① Tērā pea ka pirau te PET i te wā e tukatukahia ana i te pāmahana teitei (pērā i te whakarewatanga rewa), ka puta he iti noa iho o te formaldehyde.
② Ko ngā whakakorikori whakarewa e whakamahia ana i roto i te hanga PET, pērā i ngā matū antimony, ka whakatairanga i ngā tauhohenga taha me te whakaputa formaldehyde.
③ Tērā pea ka pirau, ka tukuna hoki te formaldehyde e ētahi tae, ngā taputapu tukatuka rānei i raro i te pāmahana teitei, i te mārama rānei.
Whakapā mai! Ka whakautu mātou i roto i ngā hāora 48.
